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.
Want to get outside, take photos that may help protect the health of Casco Bay, and connect with other community members?
We invite you to join our new volunteer Observing Network, Water Reporter, an exciting way to share what yousee around the Bay.
In 2016 and 2017, we saw a concerning increase in the number and extent of nuisance and harmful algal blooms in Casco Bay. Large mats of algae covered tidal flats, smothering animals underneath the mats, preventing juvenile clams from settling, and increasing the acidity of the sediment.
This summer and fall, we continue to be on the lookout for nuisance, green algal outbreaks—and we need your help!
For this project we are asking you to take photos of the Bay to document algal bloom events, water pollution and trash, shoreline erosion, and marine wildlife sightings. Through the Water Reporter app, your photos will be shared with Friends of Casco Bay, as well as with other observers. You will be able to see and comment on others’ posts and get an idea of what is going on around the Bay.
Each submission is displayed on a map and posted to individual, organization, and watershed feeds. To keep you in the loop, you will receive email notifications every time someone comments or takes action on your report.
In order to be a Water Reporter volunteer:
You will need a smartphone (iPhone or Android) or a tablet (iPad or Android tablet).
Create an account on the Water Reporter app and join the Friends of Casco Bay group.
Be willing to take photos of the Bay and share them on the app along with their location.
What you need to know:
Each photo you submit will provide a better understanding of conditions in the Bay.
Friends of Casco Bay is especially interested in tracking algal blooms as they occur, so if you come across one, be sure to share a photo along with the hashtag #algae.
For other reports please use hashtags like #trash #erosion #pollutionreport or #wildlife in the photo caption to improve search and categorization of your report for the community and Friends of Casco Bay.
What’s the big deal with green algae?
In the marine environment, nitrogen jumpstarts the growth of algae and phytoplankton, tiny plants that form the base of the ocean food chain, which in turn nurture zooplankton, clams, oysters, crabs, lobsters, fish, and whales. But too much nitrogen may trigger large blooms of nuisance algae or “green slime,” which can reduce water clarity and lower oxygen levels, making life harder for marine organisms. These nuisance algal blooms may be triggered by excess nitrogen from fertilizers, sewage, pet wastes, and emissions from tailpipes and smokestacks. For more information on excess nitrogen and green algae visit https://www.cascobay.org/our-work/science/nuisance-algal-bloom-tracking/.
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.
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.
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.
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.
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.
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.
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.
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.
Advance tickets for our Wild & Scenic Film Festival are sold out, but you still have the opportunity to buy tickets and attend the event! We will have a limited number of tickets available on Saturday, November 3, the day of the event. Tickets will be sold first come, first served. Doors will open at 3 p.m.
More than 125 volunteers and supporters of Friends of Casco Bay came to the Volunteer Appreciation Celebration on January 23, to recognize those who give their time to monitor the water quality of the Bay, clean up shorelines, stencil storm drains, participate in community outreach events, and serve on its Board.
At the event, ten Citizen Stewards received recognition for milestones in Water Quality Monitoring. Sarah Lyman, Community Engagement Coordinator for Friends of Casco Bay, recognized each of the honorees, remarking, “There is so much power and synergy in being able to connect data and connect people.”
Those recognized for their milestones in service:
Erno Bonebakker (25 Years)
Erno has been volunteering since 1993, the first full year of the Friends of Casco Bay’s water quality monitoring program. He and his family moved here from California in 1988, and within a week, Erno attended a meeting about the health of Casco Bay. His passion for Casco Bay has only deepened as he continues to explore, study, and care for it. He divides his time between Chebeague Island and Portland.
Dick Stevens (15 Years)
Dick Stevens has been active in the Gulf of Maine Ocean Racing Association and the Portland Yacht Club–winning a few trophies along the way. Sailing the coast and kayaking the lakes and rivers of Maine has given Dick a closer appreciation of the delicate nature of this rugged environment. This inspired him to volunteer as a Citizen Steward for Friends of Casco Bay.
Sheila McDonald and Debora Price (10 Years)
Sheila MacDonald and Debora Price have shared a sampling site at Mere Point Boat Launch in Brunswick, where they have found enthusiastic support whenever they explained why they were sampling the water quality of Casco Bay. Sheila serves as deputy director of the Maine State Museum. Debora is retired after teaching, owning a local real estate business, and co-founding an eldercare service, Neighbors, Inc.
Michelle Brown (5 Years)
Michelle has a professional background in wildlife management and natural resource conservation. Throughout her career, she has witnessed the power of volunteers and volunteering, so when she and her husband moved to Peaks Island, she was delighted to find out about the Friends of Casco Bay Citizen Stewards Program and how the data that volunteers collect provide important information about the Bay.
Craig Burnell (5 Years)
Craig always knew he wanted to become involved in the sciences, studying and learning about our environment. He works at Bigelow Laboratory for Ocean Sciences as a Research Associate in the Bigelow Analytical Services facility. When not working, he is likely to be training for his next bike race, which will include a race across the country this summer.
John Todd (5 Years)
John and his wife Cathie have summered in Phippsburg since the 1960s. They finally moved there full time in 2005 after John retired from a career in international development. They love living on The Basin, where they enjoy swimming and kayaking, especially with their grandchildren.
Jan Flinterman (5 Years)
Jan has shared coverage of a water quality site at The Basin, a saltwater inlet on the New Meadows River in Phippsburg, with John Todd and Jim Sidel. Data collected by Citizen Stewards helped convince the Maine Legislature to upgrade this popular anchorage to the highest level of water quality protection, Class SA.
Rob Sellin and Natalie West (5 Years)
Rob and Natalie spent many years sailing the world before arriving in Maine in 2011 aboard S/V Wilhelm, their 44-foot steel cutter. They settled in South Portland and have been sampling water quality at the pier at Southern Maine Community College since 2012. They sail the coast of Maine every summer, exploring the extraordinary bays and offshore islands of our state, often accompanied by their adult children and their grandchildren.
Casco Bay, like ocean water around the world, is changing and changing quickly.
We want you to know that we have changed our volunteer Citizen Stewards Program and our staff-led Water Quality Monitoring efforts in order to stay on top of the science of how the Bay may be changing.
When our organization started in 1989, no one knew the health of the Bay. That was the question we were asked—“How healthy is Casco Bay”—and that is what our first quarter-century of monitoring has enabled us to address.
Thanks to the data that hundreds of our volunteer Citizen Stewards have helped us collect over the past 25 years, in addition to data collected by our staff, we can identify where regions of the Bay are challenged, and where, generally speaking, the Bay is healthy. The snapshots of data volunteers collected are a key aspect of our Casco Bay Health Index and have been vital to our advocacy efforts. This 25-year data set has provided us with a solid foundation from which to launch this next phase of data collection.
Looking forward, our monitoring goals are to:
Understand how Casco Bay is changing with respect to climate change, ocean and coastal acidification, sea level rise, and other stressors
Conduct more intense data collection efforts in challenged regions of the Bay to try to understand why water quality is so poor, in places such as Portland Harbor and the mouth of the Harraseeket River
Involve more volunteers in our efforts to keep Casco Bay blue. While we are utilizing more technology to help us achieve our first two goals, technology will never replace the connections, energy, visibility, and goodwill that volunteers like you provide as ambassadors for the Bay.
In order to meet these goals, we are now monitoring Casco Bay through these four ways:
Our Continuous Monitoring Station collects hourly data to help us address the question “How is Casco Bay changing?” We launched this station more than a year ago, and we are excited about how much we have learned about the Bay in a short time. We intend to keep this Station operating in perpetuity.
Using data sonde technology, our staff will continue to collect data at 12 legacy volunteer Citizen Steward sites—these sites were chosen as representative of regions around the Bay and include healthy sites, challenged sites, and those in between. We think of this monitoring as “the Bay getting a checkup.” How are regions of the Bay doing? Are healthy areas remaining healthy? Are challenged areas continuing to show problems, or might they be improving?
Using our Baykeeper boat, our staff will conduct more intensive efforts in challenged regions of the Bay. If you have seen our Health Index, you have seen that there are “red dot” areas. We are looking closer at those red dot areas and asking, “what may be causing the trouble?” We began this work in 2017, as we conducted transects, from surface to bottom, and across regions, in Portland Harbor and in the Harraseeket River. We will continue to look intensively at these regions.
Using volunteer citizen scientists, we will engage the community to help us collect data and observations on a changing Casco Bay. Our volunteer program is going through a large transition. We are significantly changing the time commitments required to become a citizen scientist, and we are changing the parameters that volunteers collect. We will be asking Citizen Steward Volunteers to collect new kinds of data and record observations on changes in Casco Bay.
In 2016, you may remember that we organized a citizen science “flash mob to Nab Nitrogen.” The event was an incredible success, signaling 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 learned that we can count on our community to help us grab vast amounts of data if we make sampling easier and reduce the time commitment.
For example, we are piloting having volunteers measure the color of our waters as a biological indicator. The general public often considers blue water to indicate healthy oceans and dirty-brown water to indicate polluted water. In fact, scientists attest to color being an excellent indicator of what is happening in our oceans. For more than a century, marine scientists have used the Forel-Ule scale to document the color of oceans and lakes.
The color of our water, measured by this scale, can be an excellent environmental indicator. By using a specially designed smartphone app and a secchi disk, volunteers can help us collect scientific data on the color and clarity of our waters. The protocols for this data collection are easy to follow, and the data helps address a question we often hear: “How is the Bay changing?”
We will also ask volunteers to help us observe and keep track of nuisance and harmful algal outbreaks, which have plagued our waters these past two summers.
By revamping our volunteer monitoring efforts, we have the opportunity to broaden our network of knowledgeable ambassadors for our coastal waters—and make strides in our understanding of the Bay.
In our experience, our volunteers are some of the most active, outspoken, and well-spoken members of our community. We look forward to engaging more volunteers than ever this year. The commitment of these volunteers will send ripple effects through towns around the Bay.
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.
Since 1992, more than 650 volunteers have gotten their hands wet in our Citizen Stewards Water Quality Monitoring Program, complementing the work of our staff scientists in assessing the environmental health of Casco Bay. This science is the foundation of much of our community engagement and advocacy efforts.
Volunteer Citizen Stewards measured dissolved oxygen, temperature, salinity, water clarity, and pH at nearly 40 shoreside sites on the same date and time on ten Saturdays from April through October, to create a simultaneous snapshot of surface conditions around the Bay.
Our staff scientists have monitored offshore at 10 stations, from surface to sea floor, aboard our research vessel, every month of the year.
The data allowed us to address these questions:
How healthy is the Bay?
Where are problem areas?
What influences the health of the Bay?
What we have learned
Casco Bay is generally healthy, compared with other estuaries.
Year after year, our data has identified Portland Harbor, the New Meadows embayment, and the mouth of the Harraseeket River as the most environmentally challenged areas in Casco Bay.
The healthiest regions of the Bay are Broad Sound, Maquoit and Middle bays, and the offshore waters near Halfway Rock.
By sampling both along the shore and offshore, we determined that land-based origins contribute significant sources of excess nitrogen.
The bottom water of the Bay has become more acidic, a worrying trend that mirrors what is happening worldwide.
Summer is lasting longer beneath Casco Bay. Water temperatures are staying warmer into the fall.
In order to better understand how the Bay is changing, we are increasing the frequency of data collection.
Covered with sea squirts, sea stars, and other marine hitchhikers, the newest member of our monitoring team looks like an abandoned lobster trap. It may be homely, but we are pretty impressed with what it does, collecting water quality data hourly, 24 hours a day, 365 days a year. It is our Continuous Monitoring Station, which will help us answer the question “How are our coastal waters changing over time?” Research Associate Mike Doan calls it “the cage of science.”
It has been just over a year since we placed a carbon dioxide sensor and a data sonde—an electronic device that records temperature, pH, and other characteristics of water quality—inside this modified lobster trap and moored it in healthy waters near the center of Casco Bay off Cousins Island in Yarmouth.
After one full year, we have over 8,760 hours of data on oxygen levels, carbon dioxide, pH (the level of acidity of the water), salinity, temperature, chlorophyll fluorescence (estimated phytoplankton abundance), water clarity, and water depth.
Thanks to our 26-year data set on water quality in Casco Bay, we understand when and which areas of the Bay are likely to exhibit challenged water quality conditions that require further study. Armed with this baseline data, we can now consider how to address the question, How is the Bay changing?
The steady flow of data from the Station already is helping us detect and document how climate change and emerging coastal stressors may be affecting the Bay. Hourly data helps us identify daily, seasonal,
and annual trends to better understand the extent to which ocean acidification may be impacting the water chemistry of Casco Bay. In future years, we hope to deploy two more “cages of science,” one in challenged waters in Portland Harbor and one near Harpswell to help detect the influence the Kennebec River has on Eastern Casco Bay.
What is a data sonde?
A data sonde, such as the one being used by Research Associate Mike Doan, is an oceanographic
monitoring instrument that takes multiple measurements of water quality simultaneously. In
addition to being used as part of our Continuous Monitoring Station, data sondes are used by
staff scientists in other water quality monitoring efforts from shore and by boat. The data is
downloaded to a computer and analyzed to provide a long-term picture of water quality over
time. We thank Casco Bay Estuary Partnership and our generous members for helping fund
our Continuous Monitoring Station’s first year.
Early on in our history, Friends of Casco Bay confronted the fact that millions of gallons of raw sewage emptied into Casco Bay each year from overflowing sewer pipes. Sewage from boats was also a concern, leading us to establish a marine toilet pumpout service for recreational boats. Our advocacy for regulations to prevent cruise ships from discharging polluted water right at the dock helped make Casco Bay one of the most protected bays in the nation from vessel sewage and other wastewater.
We battled pollution on many fronts, all while building an organization based on scientific credibility and a “work with” approach. By pushing to enforce existing environmental regulations, we helped to eliminate the biggest source of pollution to Casco Bay—pulp wastes from the Westbrook paper mill. This wastewater sucked the oxygen from the Presumpscot River and delivered toxic water to Casco Bay.
As one of the busiest oil delivery ports on the East Coast, Portland needed to prepare for the very real possibility of an oil spill. Friends of Casco Bay lobbied for more training and cleanup equipment. This preparation enabled responders to recover 78% of the 180,000 gallons of oil spilled when the Julie N tanker hit the Casco Bay Bridge in 1996.
NOW—Nitrogen pollution, ocean acidification, and sinking oil—threats we didn’t even think about a generation ago
Today, Casco Bay faces new challenges. Our research shows that parts of Casco Bay are acidic enough to dissolve juvenile clams. The cause? Carbon dioxide from emissions from tailpipes and smokestacks and nitrogen pollution from sewage discharges, fertilizers, and stormwater runoff. Excess nitrogen triggers algae blooms that result in more carbon dioxide and less oxygen in seawater.
We are again warning that Portland Harbor needs to be better prepared for an oil spill, including spills of heavy crude oils, which may sink to the bottom of the Bay, making our current cleanup tools ineffective.
We often say, “Think local, act local”, a mantra that we find ourselves using more and more, as local communities become the change agents for environmental activism/progress to combat pollution and climate change. We help municipalities craft ordinances on pesticides, plastics, stormwater pollution, and other issues that later are adopted by neighboring cities and towns.
While our focus remains Casco Bay, we recognize that global climate change threatens every water body, and indeed, every individual on the planet. The impact of rising seas, warming water, and acidifying oceans is truly a game changer, creating environmental and social challenges faster than anyone anticipated.
