What’s green, microscopic, and makes half of the oxygen we breathe? Phytoplankton, the tiny algae at the base of the food chain, that’s what!
Measurements of chlorophyll — the green pigment that enables plants and algae to photosynthesize — provide an estimate of how much phytoplankton are in our coastal waters.
In this third edition of Mike’s Field Notes, Staff Scientist Mike Doan shares what he sees when he looks at our Continuous Monitoring Station’s most recent chlorophyll data. You can watch the three-minute video below.
In case you missed them, here are links to the first two videos of Mike’s Field Notes:
Let’s walk down Memory Lane together to recall our most popular stories of the year, based on your visits to our website and our social media interactions:
You answered the call when Casco Bay needed your voice
We asked our supporters to let legislators know they are concerned about climate change and the health of Casco Bay. You urged the Maine Legislature’s Committee on Marine Resources to support a bill to create a Climate Change and Ocean Acidification Commission. Your voices were heard as our bill was incorporated into the Governor’s comprehensive climate change bill, An Act to Promote Clean Energy Jobs and to Establish the Maine Climate Council, which was passed with strong bipartisan support.
Maine takes a BIG step forward to address climate change
Friends of Casco Bay fervently supported Governor Mills’ bill to establish the Maine Climate Council because it focuses on the root causes of climate change and recognizes that we must act now to remediate and adapt to inevitable change. Our Casco Baykeeper Ivy Frignoca has been appointed to the Coastal and Marine Working Group of the Climate Council.
Casco Bay Temperature Extremes
Research Associate Mike Doan is often asked, “What were the highest and the lowest water temperatures this year?” Thanks to our Continuous Monitoring Station, Mike is able to share those data with confidence. He can tell you what water conditions in the Bay are on an hourly, daily, weekly, seasonal, or yearly basis in far more detail than ever before.
Our new pumpout boat is taking care of business
On June 10, more than 100 friends cheered the christening and launch of Headmaster, the new pumpout boat specially built for Friends of Casco Bay. It transports raw sewage from the holding tanks of recreational boats to shoreside treatment. The name Headmaster is a play on the word for a marine toilet — “head” — and gives a nod to the educational and ambassadorial role of the pumpout service.
Have you seen this fin?
It’s not a shark! Several boaters on the Bay encountered Mola mola, or ocean sunfish, this summer. Its bulbous body is not designed for speed, but it can plunge down hundreds of feet in search of its favorite food: jellyfish. It then floats on its side at the ocean surface to warm up after its chilly dive.
Casco Bay Matters
In March and April, 380 people attended our first-ever Casco Bay Matters series, held at three venues around the Bay. They heard Casco Baykeeper Ivy Frignoca, Research Associate Mike Doan, and Executive Director Cathy Ramsdell speak on Climate Change, Ocean Acidification and You in Portland, South Portland, and Brunswick. By the last presentation, in Brunswick, it was standing room only. If you missed our Casco Bay Matters presentations, you can see the series of three videos on our YouTube channel.
BEE a BayScaper!
We were proud to see a BayScaper sign on the lawn of Friends of Casco Bay’s volunteer Jane Benesch. Her South Portland yard is bedecked with flower beds, vegetable patches, and wood chip-lined paths — and just a little turf. Her yard attracts butterflies and bees — and neighbors who stop to admire her winged visitors.
Keep pet waste out of the Bay!
While we were examining a pollution incident in Cumberland, we came across several dog poop bags at the outfall of a storm drain. When folks toss poop bags into a storm drain, they are not doing the Bay any favors. Storm drains often lead directly to Casco Bay. So after bagging it, deposit pet waste in a trash can or flush the contents down the toilet and throw the plastic bag in the trash.
Water Reporters report in about #sealevelrise
Volunteer Water Reporters were out taking photos of the high tides to document flooded streets, eroding coastlines, and tide levels encroaching where we don’t normally see them. Water Reporter provides a two-way conversation platform about protecting Casco Bay.
We look forward to keeping you updated in the New year. Make sure you stay on top of news about Casco Bay in 2020!
Every hour and every day, the Continuous Monitoring Station—a.k.a our “Cage of Science”—is building a more complete picture of the seasons beneath the Bay. Thanks to support from Casco Bay Estuary Partnership and generous donors, the Station collects measurements of temperature, salinity, pH, dissolved oxygen, carbon dioxide, and chlorophyll fluorescence year-round. Every other week, Research Associate Mike Doan cleans and calibrates the equipment, and downloads and graphs the data to track conditions in the Bay.
