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!

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.

Protecting the Bay from Pesticides

Executive Director Cathy Ramsdell served for nearly a year on a task force to help the city develop the ordinance.

We are delighted to share that in January 2018, the City of Portland passed one of the strongest ordinances in the state to restrict pesticide use.

Executive Director Cathy Ramsdell served for nearly a year on a task force to help the city develop the ordinance. She often found herself a fulcrum of the group, reminding everyone of their common purpose to protect Casco Bay. The ordinance is similar to one that South Portland passed in 2016, also thanks in part to Friends of Casco Bay’s advocacy. While state and federal authorities have been slow to protect our waters from these toxic chemicals, we are heartened to see local communities take action.

Why restricting pesticide use is important for the health of the Bay: We have long been concerned about the possible impacts of lawn chemicals—pesticides and fertilizers—on the environmental health of Casco Bay. Our monitoring efforts revealed that the lawn chemicals we are putting on yards can end up in the Bay. Between 2001 and 2009, we collected rain water flowing into the Bay and analyzed the samples for a suite of pesticides. Lab results identified 9 different pesticides in 14 locations all around the Bay. Pesticides do not belong in the Bay, as they have the potential to harm lobsters, fish, and vital habitat.

 

The looming question for the future— How is Casco Bay changing?

We see water itself as fundamental habitat. When water quality deteriorates, eelgrass, plankton, clams, and other marine creatures suffer. Thanks to our 25-year data set on water quality in Casco Bay, we now have a better overall understanding of the health of the Bay. We understand when and which areas of the Bay are likely to exhibit challenged water quality conditions.

Armed with this baseline data, we can now begin to address the question How is the Bay changing?—thus, the establishment last year of our first automated Continuous Monitoring Station. We will also continue to monitor selected sites at the surface, to supplement the historical data set compiled by our Citizen Stewards Program. And, we will look more intensively, using surface-to-bottom transects, at those regions of the Bay which present challenged conditions. New data and observations may help us begin to understand how climate change, excess nitrogen, and the changing chemistry of Casco Bay may be impacting the ocean food web.

Our Nabbing Nitrogen event in 2016 signaled to us that there is a huge reservoir of goodwill from people who want to help protect the health of the Bay and are willing to do that in short bursts of data collection efforts. We foresee new volunteer opportunities in this type of data collection, as well as in expanding other community service projects, such as coastal clean-ups, storm drain stenciling efforts, and issue-education events to inspire Champions for the Bay.

Citizen Steward volunteers will continue to be key to our organization as they help us move into this next phase of work to improve and protect the environmental health of Casco Bay. Casco Bay belongs to all of us, and this Bay is fortunate to have so many Friends.
