Curious 🧐 how much the salinity in EGP changes after a cut❓These maps 🗾show bottom salinity 🧂 levels before the cut on 6/9/25 and salinity levels 2 week after the cut ✂️on 6/23/25. The pond had an average salinity increase 👆of 7.89 ppt after 2 weeks of mixing!

MV CYANO is in full swing! As you enjoy the pond 💧make sure to keep an eye 👁️ for 🦠green stuff! The BOH have issued a red🔴advisory in the northern most ponds of TGP. This means that in addition to not letting your pets🐕 play in the water, the BOH advise against a fishing 🎣 and/or eating catch from, or wading or swimming 🏊‍♀️ until conditions change for the better. 

Visit our MV CYANO page for a closer look at other maps from this week! 🔗 in bio!

✂️CUT CHECK: The Edgartown Great Pond 💧 cut closed 🚫 on Monday June, 16th. On this closure day the elevation was at 0.90 ft above NAVD88 (1.28 ft above local mean sea level). The pond was open to the ocean 🌊 for 7 days almost reaching the 9-11 day cut opening target 🎯. Although not optimal, this cut still had a positive ⭐️impact on the pond! 

➡️As of 6/18 the pond elevation 📈was at 1.062 ft above NAVD88 (1.442 ft above local mean sea level). 

➡️Stay tuned for more recent elevation data and salinity 🧂levels after the Pond’s had a week to mix!

We were grateful ☺️ to be able to discuss water💧 quality and explore coastal pond ecosystems with the 3rd grade students at the Edgartown School. 

On the last day of this 3-day program the students learned about our science 🔬 equipment, what a healthy pond ecosystem looks like, and ways to keep our coastal ponds thriving. To end the day the students built their own pond ecosystems in a jar🫙 ! Thank you 👏to the 3rd grade students for joining us and sharing your knowledge 🧠and enthusiasm 🤩about our ponds!

CUT CHECK: The cut of Edgartown Great Pond remains open. As of 3pm on Monday, June 9th, the Pond was draining to the Atlantic Ocean 🌊. The breach was large and the weather calm. Let’s all hope for an excellent tidal exchange. Our thanks to the Town of Edgartown and Shellfish 🦪 Constable Rob Morrison for cutting the Pond when it needed it most. Pre-cut salinity🧂 was ~14 ppt (eelgrass prefers >20 ppt, but can still thrive >15 ppt). Going into the warm season with a cool, clean, and salty pond is the best way to ensure the ecosystem’s resilience this season. Stay tuned, more updates and data 📈 to come. Should you have cut photos and videos, please send them our way via Instagram tags or by emailing science@greatpondfoundation.org. #greatpondfoundation #marthasvineyard #water #science #edgartowngreatpond #capeandislands #edgartown #waterquality #summer #beach #barrierbeqch #ocean #atlanticocean #southshore #sand #saltlife #islandlife #tide #drain #tidal #tidalflush
