And how is your summer going?

Summer is going swimmingly here at Friends of Casco Bay, and we have a lot of good news to share:

  • Our priority legislative bill to create a state-level Climate Change and Ocean Acidification Council was incorporated nearly word-for-word into the Governor’s comprehensive Climate Change Council bill. An Act to Promote Clean Energy Jobs and to Establish the Maine Climate Council passed with strong bipartisan support. In recognition of her yeoman’s work on this issue, Casco Baykeeper Ivy Frignoca was invited to attend the bill signing by Governor Janet Mills on June 26th.

 

  • Our water quality sampling season is well underway, as we continue to add to our long-term dataset at 22 shoreside and deepwater sites around the Bay. You may see Research Associate Mike Doan and Casco Baykeeper Ivy making the rounds by land and by sea every few weeks from April through October.

    Since early June, Executive Director Cathy Ramsdell has been attending bi-weekly meetings of the South Portland Fertilizer Working Group to assist the City in drafting a fertilizer ordinance.

 

  • July 20 marks the third anniversary of the launch of our Continuous Monitoring Station in Yarmouth. Our Monitoring Station is fondly nicknamed the “Cage of Science” because its high-tech sensors are housed inside a transformed lobster trap. The instruments measure temperature, salinity, oxygen, pH, and carbon dioxide.

    Together, they collect data once an hour, every hour, year round.  At this time of year, Mike has to scrape off a new array of marine hitchhikers whenever he hauls up the Cage of Science to download data.

 

  • ‘Tis the season to think about what not to put on your lawn! With five workshops behind her, Associate Director Mary Cerullo has scheduled another five BayScaping presentations for August and beyond. She is happy to talk with neighborhood groups about green yards and a blue Bay.

 

  • There has been such a demand by community groups to volunteer for coastal cleanups and storm drain stenciling projects that Community Engagement Coordinator Sarah Lyman and summer intern Alexis Burns have been very busy. They already have hosted seven events with 106 participants who collected an estimated 238 lbs. of trash and stenciled 238 storm drains!

    Our new pumpout boat, Headmaster, was launched on June 10th to pump raw sewage from the marine toilets of recreational boats. Captain Jim Splude, our congenial pumpout boat coordinator, can go about his business more efficiently now with a new boat that has more than twice the holding capacity of the old one.

 

  • Our Water Reporter volunteer project is expanding as we hoped and planned. Nearly 40 enthusiastic volunteers attended our Water Reporter training on June 24. Volunteers continue to sign up to keep watch over specific areas of the Bay.
    July 10 was the first anniversary of Friends of Casco Bay’s launch of the Water Reporter app. To date, 162 volunteers in this observing network have made more than 500 posts. We call that a great start!

Maine takes a BIG step forward to address climate change

We have good news to share: on June 19, 2019, the Maine Legislature passed LD 1679, Governor Janet Mills’ bill to establish the Maine Climate Council.

We fervently supported the Governor’s bill because it focuses on the root causes of climate change and recognizes that we must act now to remediate and adapt to inevitable change. The Governor’s bill incorporates many elements of a bipartisan bill that Friends of Casco Bay and the Maine Ocean and Coastal Acidification (MOCA) partnership championed: LD 1284: An Act To Create a Science and Policy Advisory Council on the Impacts of Climate Change on Maine’s Marine Species. Many Friends like you contacted the Legislature in support of that bill.

Ivy Frignoca, Casco Baykeeper and the coordinator of MOCA, says, “We could not be more excited about the Governor’s Climate Council bill. It takes on the herculean but necessary task of drastically reducing carbon emissions while setting up a council with subgroups of experts to help us address and adapt to inevitable changes. As the voice of Casco Bay, we strongly commend those portions of the bill that address the impacts of climate change — including ocean acidification — on Maine’s iconic marine resources.”

The Governor’s bill establishes six working groups, including a Coastal and Marine Working Group and a Scientific and Technical Working Group. We anticipate that many of the aspects of our collective efforts to address coastal and ocean acidification will be addressed by these groups. To aid that process, Friends of Casco Bay, as coordinator of MOCA, will meet with other partnership members this summer to create a marine climate change action plan. We look forward to sharing that plan with the Governor’s Council and will stand ready to serve as a resource to the Council.

Aquaculturists, resource harvesters, and lobstermen supported passage of this legislation. Bill Mook, owner of Mook Sea Farm, says “For those of us whose livelihoods are so tightly linked to a healthy environment, the passage of Governor Mill’s climate bill has rekindled hope. We must now show the rest of America how the path to a clean energy future will not only lead us to a healthier environment, but it will also take us to a vibrant, inclusive, and healthy economic future.”

Richard Nelson from Friendship, Maine, applauds the positive approach the state is taking on climate change, “As a lobsterman and, at times, spokesman for climate’s ill effects on the ocean’s realm, I would readily shed that position as harbinger and turn instead to being a participant in the real actions to combat it, as put forth in the Governor’s bill.”

The comprehensive bill sets tough goals to reduce Maine’s carbon footprint. It provides that by 2050, Maine must reduce our greenhouse gas emissions by 80% and get 100% of our electricity from renewable sources. The bill sets a pathway for achieving the goals in a statewide plan in order to turn these targets into actions. At a time when the federal administration is resistant to exploring mitigation and resiliency efforts, Maine is joining a growing number of states taking the lead to address climate change to collectively make a difference.

Governor Mills is expected to have a signing ceremony for the bill soon, and the Climate Council will likely begin its work this fall.

Casco Bay Matters: Advancing the conversation—and action—on climate change

Mike and Ivy on the Boat

Living close to the ocean, Casco Bay residents are witnessing the effects of climate change happening here now: warming water temperatures, increasing ocean acidity, and more severe storms. We too are seeing the changes in our data and when we are out on the Bay.

From April through October, our Research Associate Mike Doan and Casco Baykeeper Ivy Frignoca are on the Bay frequently to monitor water quality, follow up on pollution reports, or meet with partners on issues best understood from the water. Their vigilance gives them a firsthand view of changes happening in our coastal waters.

Mike, Ivy, and Executive Director Cathy Ramsdell shared these and other observations in our first-ever Casco Bay Matters series. Nearly 400 people attended Ocean Acidification, Climate Change and You presentations about what we are learning about a changing Casco Bay.

They shared how Mainers are working together to shape policies and actions to respond to these threats. Ivy is coordinating the Maine Ocean and Coastal Acidification partnership, a diverse coalition of scientists, lawmakers, aquaculturalists, and seafood harvesters, who collaborate on research and strategies to confront the threats that climate change and acidification pose to Maine’s marine resources. We also are working with legislators to pass a bill to create a state-sponsored Science and Policy Advisory Council on the Impact of Climate Change on Maine’s Marine Species.

Casco Bay Matters Intro Video

If you missed our Casco Bay Matters presentations of Ocean Acidification, Climate Change and You, you are in luck — our stalwart volunteer Deb Dawson recorded and edited videos of our South Portland (March 25, 2019) event. See the series of three videos on our YouTube channel.

Highlights from Casco Bay Matters:

Warmer waters: Friends of Casco Bay has been tracking water temperatures for over a quarter century. On average, water temperatures in Casco Bay have risen 2.5°F (1.4°C) since 1993. The growth, reproduction, and survival of marine life are influenced by temperature.

Rising Water Temperatures in Casco Bay

More carbon dioxide in our coastal waters from air and from land: We know that burning fossil fuels adds carbon dioxide to the atmosphere, trapping heat and warming the planet. Nearly 30% of atmospheric carbon dioxide is absorbed by the ocean. Carbon dioxide mixes with water to form carbonic acid, making the water more acidic. This is ocean acidification.

Maine’s nearshore waters are also at risk from coastal acidification. Excess nitrogen from sewage treatment plants, polluted stormwater, and fertilizers can stimulate massive algal growth. When the algal blooms die, decomposition depletes the area of lifegiving oxygen and releases carbon dioxide, further acidifying the water.

Threats to the ocean food web: More carbon dioxide in our waters means less shell-building material (calcium carbonate) for clams, mussels, and planktonic creatures that support the ocean food chain. Data from our Continuous Monitoring Station enable us to calculate the calcium carbonate saturation state — what scientists term omega aragonite — which can tell us whether, at any given time, enough calcium carbonate is readily available to shell-building creatures. Shell formation becomes more difficult for some species when the amount of available calcium carbonate falls below a 1.5 aragonite saturation state.

Our data indicate that for part of the year, levels of calcium carbonate in Casco Bay fall below the threshold for optimal shell-building for some species.

Sea level rise: As water warms, it expands, and the seas encroach on our coastline. Coastal observers and property owners are reporting more erosion.

Increasing precipitation: Maine has seen a six-inch rise in average annual precipitation since 1895, further threatening coastal properties. Torrential rains intensify erosion and flush overloads of nitrogen, pollutants, and sediments into coastal waters.

Those who depend upon the sea can attest to the fast pace of change. What do these changes mean for Casco Bay?

  • As oceans become more acidic, we can anticipate more pitting or thinning of the shells of many commercially viable species in Casco Bay, such as clams, mussels, and oysters.
  • Voracious green crabs — which eat juvenile shellfish — thrive in warming waters.
  • Rising water temperatures are linked with shell disease in crustaceans, directly impacting Maine’s iconic lobster fishery.
  • Scientists and lobstermen are documenting lobster populations shifting north and east.
  • Copepods, tiny crustaceans that are the main food source for juvenile lobsters, may not be as plump as they once were. In laboratory experiments that simulate climate changes now happening in the Gulf of Maine, copepods were less fatty. With a less nutritious diet, young lobsters must divert energy from growth and resisting disease to finding enough food to survive.

Testimony in support (with amendments) of LD 1679: An Act To Establish the Maine Climate Change Council To Assist Maine To Mitigate, Prepare for and Adapt to Climate Change (Governor’s bill)

Re: Friends of Casco Bay and Maine Ocean and Coastal Acidification (MOCA) Steering Committee testimony in support (with amendments) of LD 1679: An Act To Establish the Maine Climate Change Council To Assist Maine To Mitigate, Prepare for and Adapt to Climate Change (Governor’s bill)

Dear Senator Carson, Representative Tucker, and Distinguished Members of the Environment and Natural Resources Committee,

Introduction to Support for Bill with Amendments:
Friends of Casco Bay and the Steering Committee of the Maine Ocean and Coastal Acidification (MOCA) partnership submit the below testimony in support of LD 1679, An Act To Establish the Maine Climate Change Council To Assist Maine To Mitigate, Prepare for and Adapt to Climate Change (Governor’s bill). We support the bill but recommend four amendments to better address the impacts of climate change to Maine’s marine species and habitats. These amendments are set forth in the attached track-changes document and below:

  • Amend Section 11 (38 MRSA § 578) – which requires the Council or Department to provide evaluation reports to this Committee and the Energy, Utilities and Technology (EUT) Committee – to also require reports to the Marine Resources Committee (MRC) and to authorize the MRC to make recommendations to this Committee.
  • Amend Section 10 (38 MRSA §577-A) (8) to include recommendations for scientific monitoring and research to fill data gaps needed to spur action or evaluate remediation and adaptation strategies.
  • Amend Section 10 (38 MRSA §577-A) (6) to specify that the Scientific Subcommittee should provide technical support to the working groups and should contemplate creating subgroups of experts to support the working groups.
  • Amend Section 10 (38 MRSA §577-A) (1) to include representation by a fisherman and by an aquaculturist.

Who We are:
Friends of Casco Bay is a nonprofit marine stewardship organization dedicated to improving and protecting the environmental health of Casco Bay. We scientifically monitor and assess water quality, including parameters indicative of climate change and ocean acidification. We employ a Casco Baykeeper, who serves as the lead advocate, or eyes, ears and voice of the Bay. We engage in significant public outreach including citizen science and other actions to engage our members and volunteers in our work to improve the health of the Bay.1

Maine Ocean and Coastal Acidification (MOCA) is a voluntary partnership formed to implement recommendations of the Ocean Acidification Study Commission authorized by the 126th Legislature (see study commission’s report).2
Friends of Casco Bay, the Island Institute, and Maine Sea Grant convened MOCA when the State failed to establish an on-going council to implement the Study Commission’s recommendations. Friends of Casco Bay has served on the MOCA Steering Committee since its inception and as its Coordinator for the last two years. MOCA has been most effective as an interim forum for coordinating and sharing research among public and private entities and as an information exchange.

Testimony on the Marine Aspects of LD 1679:
We support the overall concept of working across sectors to mitigate and adapt to climate change. Because our expertise is with respect to the health of marine waters, we will confine our testimony to those aspects of the bill.

To paraphrase Governor Mills’ inaugural address, we must act now. Climate change is already impacting Maine’s fisheries and habitats:

  • About a third of all carbon dioxide emitted into the atmosphere is absorbed by the ocean, where it mixes with sea water to form carbonic acid and lower pH. This process is known as ocean acidification. In Casco Bay, pH has dropped from 8 to almost 7.8 from 2000-2012. The pH scale is logarithmic, meaning that a decrease of an integer value changes the concentration by tenfold. Lower pH (more acidic water) can cause mollusk shells—including clams, oysters, and mussels—to pit and dissolve.
  • Annual precipitation in Maine has increased six inches since 1895, and we are experiencing more intense storms that deliver excess nitrogen to marine waters. The nitrogen fuels algal and phytoplankton blooms. The blooms have immediate negative impacts on marine species. For example, we have seen thick mats of nuisance algae smother clams. In addition, as blooms die, they release carbon dioxide which mixes with sea water to form carbonic acid. This process is known as coastal acidification and also lowers the pH of our coastal waters.
  • The temperature of Casco Bay rose about 1 degree Celsius (2.5 degrees Fahrenheit) from 1993 to 2018. Warmer ocean temperatures mean that green crabs are not dying back over the winter. The higher populations of green crabs prey on soft-shelled clams and other mollusks. They also demolish eelgrass beds, a critical marine habitat. Rising ocean temperatures also cause shifts in species and can contribute to an increase in lobster shell disease.
  • In 2016, we began measuring the amount of calcium carbonate available for mollusks and other organisms to build their shells. We learned that for most of the year, there is not enough calcium carbonate in the water for shell-building.

Prior to news that Governor Mills would introduce her comprehensive Climate Change Council bill, Representative Lydia Blume worked with MOCA to draft LD 1284: An Act To Create the Science and Policy Advisory Council on the Impact of Climate Change on Maine’s Marine Species. The MRC held a hearing on that bill on April 2, about a month before the Governor’s bill was printed.

135 people from Friends of Casco Bay, MOCA, and other entities submitted testimony in support of LD 1284. No one testified against the bill. The Environmental Priorities Coalition selected the bill as a priority; industry leaders such as Mook Sea Farm and the Maine Aquaculture Association supported the bill; and leading marine research institutes, including Gulf of Maine Research Institute, Island Institute, Downeast Institute, and University of Maine, offered their support. The Ocean Conservancy‘s CEO sent a letter of support and separately authorized retired Congressman Tom Allen to appear and testify on their behalf.3

Commissioner Keliher testified and asked the MRC to delay further consideration of LD 1284 because the Governor intended to incorporate it into her bill. The MRC honored that request. We have reviewed and support LD 1679; it incorporates most of the intent of LD 1284 but fails to require progress reports to the MRC and afford opportunities for the MRC to make recommendations to this Committee.

We respectfully request that you amend the bill in that respect, and consider and address the other suggested amendments and comments on the attached track-changes document. Thank you for your attention to our testimony.

Sincerely,
Ivy Frignoca
Casco Baykeeper
Friends of Casco Bay

A call to action before Tuesday: make your voice heard

Photograph by Kevin Morris

Casco Bay needs your help! Please take a few minutes to let legislators know you are concerned about climate change and the health of Casco Bay.

On Tuesday, April 2, at 1 p.m., the Committee on Marine Resources of the Maine Legislature is holding a public hearing on a bill we strongly support: LD 1284, “An Act to Create the Science and Policy Council on the Impact of Climate Change on Maine’s Marine Species.”

The bill will establish a council made up of legislators, scientists, resource harvesters, and other stakeholders, with a mission to evaluate the impacts of climate change on Maine’s marine species and to make statewide policy recommendations.

This bill moves Maine to action on addressing and adapting to climate change, ocean acidification, sea level rise, and other threats to the health of our coastal waters. We believe Maine must act now to protect coastal habitats and marine species.

We ask you to urge the Committee on Marine Resources to vote in favor of LD 1284. Let them know you are concerned about climate change and its impacts on Casco Bay and on all of Maine’s marine resources.

Please email the committee by Tuesday morning, April 2.

Here are suggested talking points for your email — we strongly recommend that you put these in your own words. Links below provide more information.

Dear Senator Miramant, Representative McCreight, and Members of the Committee on Marine Resources:

I am writing to you to urge you to vote in favor of LD 1284, “An Act to Create the Science and Policy Council on the Impact of Climate Change on Maine’s Marine Species.”

Maine’s coastal waters are changing and changing quickly. Friends of Casco Bay has been tracking water temperatures for over 25 years. On average, the data show a 2.5° F increase in water temperatures since 1993.

About 30% of the carbon dioxide released into the atmosphere is being absorbed by the ocean. This is increasing the acidity of our marine waters and reducing the availability of the material (calcium carbonate) that clams, mussels, and other shellfish need to build their shells. Recent data indicate that for nearly half the year, levels of calcium carbonate in Casco Bay are not sufficient for shell-building.

Our marine heritage and economy depend upon healthy coastal waters. The Science and Policy Council that LD 1284 will create will help move Maine forward on addressing and adapting to changes that threaten our marine resources.

Thank you for your time and service to Maine.

Sincerely,

–Your name and town you live in

Once you have emailed the committee, please let us know by emailing me back at keeper@cascobay.org. I will be testifying at the hearing on Tuesday, and it would be great to know that we have your support.

Thank you for making your voice heard for Casco Bay!

 

More information:

We have a wealth of information about the impacts of climate change on Casco Bay: https://www.cascobay.org/climate-change-ocean-acidification-and-you/

LD 1284 was proposed by Representative Lydia Blume (York), who is a member of the Committee on Marine Resources. You can read the official language of the bill here.

LD 1284 has been selected by the Environmental Priorities Coalitiona group of 34 environmental organizations, as one of its five priority bills to address climate change in Maine.

As we shared with you at our Casco Bay Matters event, Governor Mills has proposed an all-encompassing Climate Change Council. Her proposal, which will be considered in separate legislation, will likely incorporate the council created by LD 1284 into a subcommittee of her omnibus council. We support the Governor’s plan and want to be sure that there is adequate focus on the marine environment — which is why it is so important that you make your voice heard on this issue.

Climate Change, Ocean Acidification, and You

Climate Change Science and Data

  • The climate is changing faster than expected. Greenhouse gases, such as carbon dioxide and methane, are the culprits. The burning of fossil fuels for homes, industry, and transportation releases almost 10,000 million metric tons of carbon dioxide into the atmosphere every year. 1
  • Carbon dioxide is changing not only our climate, but also the chemistry of the ocean. About 30% of the carbon dioxide we release into the atmosphere is absorbed by the ocean. 2 In marine water, carbon dioxide decreases pH and increases acidity through a process known as ocean acidification.
  • Excess nitrogen from sewage treatment plants, polluted stormwater, and fertilizers, is also adding carbon dioxide into nearshore waters through a process known as coastal acidification. 3
  • Nitrogen can fertilize massive algal growth in our waters. When the algal blooms die, decomposition depletes the area of life-giving oxygen and releases carbon dioxide, acidifying the water.

The impacts of climate change are evident right here in Casco Bay

Warmer Waters

Friends of Casco Bay has been tracking water temperatures for over 25 years. On average, our data show a 2.5° F increase in water temperatures since 1993.

Sea Level Rise

As water warms, it expands, and the sea encroaches on our coastline. Coastal observers and property owners are reporting an increase in erosion.

Increasing Precipitation

Maine has seen a six-inch average increase in annual precipitation since 1895, further threatening coastal properties. 4

Threats to the Ocean Food Web

More carbon dioxide in our waters means there is less shell-building material (calcium carbonate) for clams, mussels and oysters, as well as for tiny critters at the base of the ocean food chain. The saturation state of calcium carbonate is a key measurement of shell-building material for many organisms. Shell formation becomes more difficult when the amount of available calcium carbonate falls below a 1.5 saturation state. 5 Our recent data indicate that for nearly half the year, levels of calcium carbonate in Casco Bay are not sufficient for shell-building.

What do these changes mean for Casco Bay?

  • Research Associate Mike Doan with our Continuous Monitoring Station. The Station houses a number of instruments that collect data on carbon dioxide, temperature, salinity, oxygen, chlorophyll, and pH, hourly, 365 days a year. This large quantity of data is necessary to accurately track changes in the Bay from climate change, including ocean and coastal acidification.

    As marine waters become more acidic, we can anticipate more pitting or dissolution of the shells of many commercially viable species in Casco Bay.

  • Rising water temperatures are linked with shell disease, directly impacting our lobster fishery and tourism industries.
  • Climate change is bad news for clams because green crabs — which eat juvenile shellfish — thrive in warming waters. 6
  • The distribution and populations of marine species in the Gulf of Maine are shifting. Scientists and lobstermen are documenting the shift in distribution of Maine’s iconic lobsters north and east.
  • Copepods are tiny crustaceans that are the main food source for juvenile lobsters. In laboratory experiments, copepods raised in conditions that simulate the climate changes occurring in the Gulf of Maine were less fatty. With a less healthful diet, young lobsters must divert energy from growth and resisting disease to finding enough food to survive. 7

What is Friends of Casco Bay doing?

  • We helped form the Maine Ocean and Coastal Acidification Partnership (MOCA) to coordinate climate change research and policy change work. MOCA is a diverse coalition of researchers, policy experts, lawmakers, aquaculturalists, and seafood harvesters. We are working to create an action plan for Maine to protect the health of our coastal waters.
  • LD 1284 has been selected by the Environmental Priorities Coalition, a group of 34 environmental organizations, as one of its five priority bills to address climate change in Maine.
  • Our Water Reporter volunteers are recording observations of how the Bay is changing. These observations strengthen our advocacy efforts as these reports are shared with regulators, legislators, and other decision makers, alerting them to conditions in the Bay.

What can you do?

  • Tell your legislators to support LD 1284 to create a science and policy advisory council to address the impacts of climate change on Maine’s marine species.
  • Join Water Reporter. Your observations combined with those of other volunteers around the Bay will provide a better understanding of changing conditions.

Ocean Acidification, Climate Change, and You: A Casco Bay Matters Event

Climate change is affecting the health of Casco Bay faster than anyone could have predicted. Warming temperatures and increasing acidity threaten the ocean and the livelihoods of those who depend on the sea. Research is showing that changes in our coastal waters from climate change are putting lobstering, clamming, and aquaculture at risk.

Friends of Casco Bay invites you to attend Ocean Acidification, Climate Change, and You, a free event, open to all.

Staff scientist Mike Doan will talk about the warning signs we see in our monitoring data. Casco Baykeeper Ivy Frignoca will share some of the impacts to our marine species and how Mainers are working together to respond to these threats. They look forward to your questions following the presentation.

Healthy marine waters are vital to Maine’s economy and quality of life.This is such an important issue that we are hosting this presentation at three locations in the coming weeks: Portland, South Portland, and Brunswick.

On July 20, 2016, our Continuous Monitoring Station began recording data hourly, 365 days a year. We are excited to share the first two and half years of data, collected at our water quality monitoring site in Yarmouth, near the coastal midpoint of Casco Bay. We will update these graphs monthly, so come back often and see for yourself how Casco Bay is changing.

See the data

See sea critters and our Cage of Science

Watch this short video about the Cage of Science!

You may know that Friends of Casco Bay’s Continuous Monitoring Station—AKA our “Cage of Science”—gives us vital data about the health of the Bay. But did you also know that observations of what sea life is growing on and hanging out in the station also give us important information about conditions of our waters? In this video, Research Associate Mike Doan shows us some of the sea critters that visited the Cage of Science in August.

Thanks to support from Casco Bay Estuary Partnership and generous donors, our Continuous Monitoring Station collects data once an hour, every hour, year round.

Out and About with the Casco Baykeeper

Out and About with the Casco Baykeeper

As always, Casco Baykeeper Ivy Frignoca has been on the move, working across Casco Bay, the state—and the nation—on efforts to protect the environmental health of Casco Bay.

A peek into her appointment calendar shows some of the highlights so far this year, as she continued to track Legislative issues and to comment on proposed wastewater and stormwater discharge permits that the Department of Environmental Protection issues to municipalities.

January

I became coordinator of the Maine Ocean and Coastal Acidification Partnership (MOCA) for 2018.

I will help coordinate research and advocacy on ocean acidification with a strong statewide network of policy makers, fishermen, shellfish growers, and scientists. This year-long role supports our work examining coastal acidification and excess nitrogen.

February

I invited Portland’s Water Resources Manager, Nancy Gallinaro, and Portland Water District’s Director of Wastewater Services, Scott Firmin, to travel with me to meet the new Environmental Protection Agency (EPA) Region 1 Administrator, Alexandra Dapolito Dunn. We highlighted our joint efforts to reduce nitrogen pollution, combined sewer overflows, and stormwater pollution to Casco Bay. I shared our data showing the impacts of climate change on Casco Bay.

Our Casco Baykeeper meets EPA Administrator Alex Dunn.

 

Administrator Dunn accepted our invitation to come to Maine in June to attend a meeting of the Maine Nutrient Council, a group convened by Casco Bay Estuary Partnership. Afterward, Administrator Dunn will tour the Bay on our Baykeeper boat, a great opportunity for a close-up view of issues that threaten the water quality of Casco Bay.

March

Senator Angus King greets fellow Mainers Bill Mook, Hattie Train, Ivy Frignoca, and Richard Nelson.

I traveled to Washington, DC, at the invitation of Ocean Conservancy, to meet with our Congressional delegation and ask for full funding for the National Oceanic and Atmospheric Administration and the EPA. The measures we pressed for passed in the omnibus budget!

Back in Maine, I submitted comments opposing offshore drilling and then attended a meeting hosted by the Bureau of Ocean and Energy Management, to voice Friends of Casco Bay’s opposition to offshore drilling. I supported a resolve that was passed unanimously by our state legislature expressing its opposition to offshore drilling.

April

I testified at a public hearing as we worked to swiftly defeat a bill that would have practically eliminated the ability of municipalities to pass pesticide ordinances. If you contacted legislators after receiving our email alert about this issue, thank you! The bill was defeated!

I traveled to New Hampshire to attend a meeting of experts concerned about the rise in harmful algal blooms throughout the region, so we could learn more about new species appearing in Casco Bay.

May

I attended a meeting in West Bath, which drew together people who live and work along the New Meadows River, to discuss how expanding efforts in aquaculture may figure into the many uses of the estuary.

Research Associate Mike Doan gave Kate Simpson and Kayla McMurray, staffers for Senator Susan Collins, a ride to our Continuous Monitoring Station in Yarmouth. I met them at our “Cage of Science” as we demonstrated how we use technology to monitor the Bay hourly, 365 days a year. We explained that though we do not receive funding directly from the EPA, the Agency has a vital role in advising state regulators on strategies to reduce pollution, funding other research, and enforcing the Clean Water Act. This work helps us all protect the environmental health of Casco Bay.

June

The Portland Water District (PWD) hosted a ribbon-cutting ceremony to celebrate the completion of the massive, $12 million project that upgraded the aeration system at the East End Wastewater Treatment Facility. This improvement could ultimately reduce nitrogen in the treated sewage released into the Bay by up to 1000 lbs. a day! PWD’s General Manager Carrie Lewis recognized our contribution “to understanding the issues affecting Casco Bay and make positive contributions towards collaborative solutions.”

The Maine Ocean and Coastal Acidification Partnership (MOCA) is a volunteer partnership that seeks to coordinate the work of governmental agencies and private organizations and citizens who are studying and implementing means to reduce the impacts of or help adapt to ocean and coastal acidification.

The Maine Ocean and Coastal Acidification Partnership (MOCA) is a volunteer partnership that seeks to coordinate the work of governmental agencies and private organizations and citizens who are studying and implementing means to reduce the impacts of or help adapt to ocean and coastal acidification.

With my colleagues in the MOCA Partnership, I hosted a workshop for nearly 60 scientists, harvesters, policy makers, and advocates on What We Know about Ocean Acidification and Maine’s Lobsters. The event at Bowdoin College featured current research on the effects of climate change on lobsters and emphasized the need for ecosystem-level, long-term studies.

As the year progresses, I look forward to continuing to keep you updated on the biggest issues affecting the health of the waters we all love.
