Last week we had the opportunity to meet with students from the Charter School to talk about how we measure abiotic🧂🌡️🌊 water quality parameters when we monitor the ponds💧. Students explored our most used field 🛶and lab 🥼 equipment and collected their own data📊! Thank you @mv_public_charter_school for joining us and sharing your curiosity and enthusiasm‼️ #science #learning #greatpondfoundation #students #waterquality #charter #school #explore #equipement #secchi #fish #fun #outside #sunny #vandornsampler #ysi #lab

THAT’S A WRAP✅! 

Our last sampling run on Edgartown Great Pond 💧marks the end of another great field season. Stay tuned for off-season updates and winter ❄️ logger deployments!

Nutrient day always brings smiles😁! This week the team sampled 📍Edgartown Great Pond and 📍Chilmark Pond for our regular water quality monitoring and our once a month nutrient samples💧. This run marked our last nutrient run for the field season, it’s a bittersweet feeling. We bring the nutrient samples over the @mblwoodshole for filtering and processing to find out the NITROGEN & PHOSPHORUS concentrations in the ponds. ✴️Nutrient data results get back to us later in the off-season, we will keep you updated 😉 Cheers to the last nutrient day of the 2025 field season👏! #greatpondfoundation #edgartowngreatpond #chilmarkpond #nutrients #feild #boat #row #science #lab #water #happy #smile #fun #outdoors #team

‼️THIS WEEK ON THE PONDS‼️

Another science packed week for the GPF team 💪We sampled 5️⃣ ponds….

 ➡️Edgartown Great Pond
 ➡️Chilmark Pond 
 ➡️Crackatuxet 
 ➡️Tisbury Great Pond 
 ➡️Watcha Pond 

⭐️We also did some much needed logger maintenance 🧼on the Chilmark Pond bottom feeders and elevation 📈logger. 

✴️Next week we will be diving into nutrient sampling, let’s hope for a day of good weather 🤞

Last week our team installed a digital rain 🌧️ gauge near Jobs Neck Cove on Edgartown Great Pond. This is our second rain gauge on the Island. Our first, joined with @chilmarkpondfoundation was installed in 2023 along the eastern shoreline of Chilmark Pond. 

➡️These digital rain ☔️ gauges record rain accumulation per hour⏳in 1/100th inch intervals. This provides us with precipitation accumulation, rate of accumulation, and a timeline of precipitation events. 

👉This data will help us better understand the impact of rain 💧and groundwater influx patterns in the Edgartown Great Pond ecosystem. 

⭐️Thank you to the landowner who allowed us to install this device on their property!
