Local estuary programs partner for their 5th annual celebration of estuaries-the special places where rivers meet the sea.

Estuaries are bodies of water at the intersection of rivers and the ocean – where freshwater and saltwater meet and mix. Because of their unique chemistry and characteristics, they are hugely important ecosystems that provide food, shelter, and nursery grounds for countless species of plants and animals. Many, like the Long Island Sound estuary, are also close to major cities and help support local economies through tourism, transportation of goods, and more.

National Estuaries Week (September 17 -24, 2022) celebrates these unique ecosystems, brings awareness to their importance, and encourages their conservation.

This year, Long Island’s estuary programs – the Long Island Sound Study national estuary program, the Peconic Estuary Partnership (PEP), and the South Shore Estuary Reserve – are celebrating by sharing a National Estuaries Week 2022 Map. The interactive map highlightings upcoming September opportunities to head outside and engage in coastal cleanups, educational events, and more.

National Estuaries Week kicks off Saturday, September 17 with International Coastal Cleanup Day. Hosted in New York by the American Littoral Society and by Save the Sound in Connecticut, the cleanups bring thousands of volunteers to the shore annually to help pick up debris and collect valuable data on the types of trash found on beaches. Interested volunteers can access the map to find a cleanup near them, or even organize their own beach clean-up anytime from September through to December.

In addition to the events map, the local estuary programs will also be attending several of the upcoming highlighted events to share information about their respective estuaries. Find Long Island Sound Study’s booth at Setauket Harbor Day, the Women’s Fishing Expo, Family Fun Day, the Oyster Festival, Viva la Sound, and more.

Happy National Estuaries Week!

Diamondback terrapins (Malaclemys terrapin) are the only aquatic turtle that lives in brackish waters (a mix of fresh and saltwater). Special glands around its eyes let it flush out excess salt from its body, similarly to sea turtles. While their main habitat is brackish water, they are able to venture out into freshwater and saltwater and can survive in a wide range of salinity levels, a useful adaptation for life in a constantly-changing estuary.

There are seven subspecies of diamondback terrapin; the one that calls Long Island Sound home is the Northern diamondback terrapin which can be found all the way from Cape Cod in Massachusetts down to Cape Hatteras in North Carolina. Other subspecies can be found all along the eastern coast south to Florida and around the Gulf Coast through Texas.

Diamondback terrapins owe their name to the diamond-like rings on the scutes (plates) of their shell. Their scutes are made of keratin (like our fingernails) and each terrapin’s ring pattern is unique to them (like our fingerprints are to us). Females tend to be larger and have shorter tails than males, with a male’s carapace (shell) growing up to 5 1/2 inches long and a female’s up to 9 inches.

Terrapins can live 25 to 40 years in the wild, making them one of the longest-living animals in our region. They live most of their life in water, only leaving it to bask or to nest. They can be spotted poking their heads out of the water in tidal marshes or basking in the sun near mud flats and creek banks.

Diamondback terrapins mate during the early spring months and females come ashore to lay their eggs in sandy areas like beaches and dunes between May and July. They can travel quite a way inland in search for the perfect location to dig their nest, crossing streets in coastal areas (so remember to drive especially carefully around coastal zones during the summer months).

Once a terrapin has found a location for its nest, it will dig a hole around 4 to 8 inches deep using its hind legs, lay its eggs (4-15) and cover the nest with debris and pebbles.

Like in most turtle species, a diamondback terrapin’s sex is determined by the temperature of its nest. Cooler nests tend to have more males while warmer nests produce more females.


Back in the day, these turtles were plentiful and a common item in everyday diet for many people in the East and South Coast of the US. Around the 18th and 19th century, their popularity boomed as terrapin soup became a widespread culinary delicacy, and their numbers plummeted. Fortunately, because sherry was one of the main ingredients in terrapin soup, people mostly stopped eating it during the Prohibition in 1920 – 1933, which helped terrapin populations bounce back. Check out this article from NPR to learn more.

Harvesting terrapins is no longer legal in most of the US, including New York and Connecticut, and many protections are in place to protect them. However, terrapins still face threats.

Highly developed coastlines mean terrapins have less nesting habitat, forcing females to cross dangerous roads in their search. Nests are also predated on by raccoons, foxes, and skunks, and hatchlings are often predated by birds on their way to the water. Diamondback terrapins are also threatened by collisions with boats and by getting trapped in crab cages and drowning.

What You Can Do

  • Drive your boat carefully around tidal marshes, where terrapins might be swimming near the surface, and keep your eyes peeled for their heads peeking from the water.
  • Drive your car carefully along coastal roads, especially during the summer months when females might be around! If you spot a terrapin crossing the road, grab it carefully by the carapace (shell) and move it to the side of the road where it was headed.
  • If you spot a female nesting, stay away. Spooking a nesting female by getting too close may drive her to abandon her nest.
  • Help monitor for terrapins and identify potentially dangerous crossing zones by reporting any sightings! You can do so for Long Island through Terrapin Watch and in Connecticut through Terrapin Tracker or the iNaturalist app.

The spring 2022 issue of Sound Update focuses on Long Island Sound Study’s Year in Review of 2021. Various clean water, habitat restoration, education, and science projects from Connecticut and New York are highlighted, including the new Long Island Sound Marine Debris Action Plan, Community Science Long Island 2021, and the latest findings on hypoxia in the Sound.

STONY BROOK AND QUEENS, NY (March 7, 2022): On a chilly October morning in 2019, teachers Amy Olander and Veronica Morabito-Weeks excitedly set up oyster tanks and put model-making materials like aluminum trays and sponges over tables at the Cedar Beach Nature Center in Mount Sinai. They were getting ready to host their very first Mentor Teacher Workshop on nitrogen pollution, where they would later share with fellow teachers some of the interactive activities, games, and lessons they used in their own classrooms to teach their students about Long Island Sound. The weekend after that, educators Hildur Palsdottir and Leah Master held their workshop on plot studies at the Sands Point Nature Preserve, where they led fellow teachers on a walking tour of the grounds, tested the sand for microplastics, and tried out different kinds of portable microscopes together. These fun workshops would be the last of their kind in a while for the Long Island Sound (LIS) Mentor Teacher Program, which like many other in-person programs had to take a hiatus during the height of the coronavirus pandemic in 2020 and 2021. 

This year, the LIS Mentor Teacher Program is back and accepting applications from 5th to 12th-grade educators interested in leading workshops for 2022! — see our “Call for Mentor Teachers” (pdf).

Hosted by New York Sea Grant and the Long Island Sound Study national estuary program, the LIS Mentor Teacher Program provides technical and financial support to selected pairs of teachers to organize professional development workshops for their peers. The hands-on interdisciplinary workshops include a field component and center around Long Island Sound topics, with past workshops covering geology, water quality, marine debris, and more.  

The 2022 LIS Mentor Teacher Program is encouraging topics centered around climate change adaptations, sea-level rise, and ecological health. Three pairs of educators will be selected to conduct one workshop per team and will be given a $1,200 stipend per teacher, a travel budget, and a workshop budget to cover materials, location, etc. New York teachers across Queens, the Bronx, Westchester, and Long Island are encouraged to apply! 

Teachers can look forward to joining these workshops in the Fall. Ultimately, the lessons, activities, and programs shared during these workshops will help inspire students throughout New York to explore, understand, and take care of the amazing resources Long Island Sound has to offer.

Islip, NY (June 15, 2021)- The Long Island Coastal Bioblitz is an event to engage the Long Island community in exploring all of the island’s incredible habitats and species diversity. Hosted in partnership with Seatuck Environmental Association, Long Island Sound Study, Peconic Estuary Partnership, South Shore Estuary Reserve, New York Sea Grant, and the Long Island Invasive Species Management Area, one of the main goals of the bioblitz is to better understand the ecological community and biodiversity around Long Island. This information can guide environmental groups in better preserving important habitats and wildlife.

A bioblitz is a community science effort to record as many species as possible within a designated location and time period. The Long Island Coastal Bioblitz will be held “virtually,” allowing participants to record their observations using the iNaturalist app. All a participant would need to do is take a picture of any species they are looking at, plant or animal, load it into the iNaturalist app, and the species will automatically be added to the Long Island Coastal Bioblitz!

A training webinar will be provided on June 23rd at 7:00 pm to introduce participants to the iNaturalist app and the bioblitz format. Attendance is not mandatory to participate in the bioblitz but it is highly recommended. Registration for this webinar is required, and participants can register here: https://zoom.us/webinar/register/WN_McuA6dGjRWe3q0YV0SIPcA. The Long Island Coastal Bioblitz will then take place from June 26th to July 3rd. Anyone can participate using the iNaturalist app and by logging into the Long Island Coastal Bioblitz iNaturalist project page (https://www.inaturalist.org/projects/li-coastal-bioblitz). A map of suggested locations to observe wildlife, as well as a list of habitats and species you may observe in those locations, will be provided to bioblitz participants. There will also be prizes for participants who log the most observations over the week-long event!

The spring 2021 issue of Sound Update focuses on Long Island Sound Study’s Year in Review of 2020. Various clean water, habitat restoration, education, and science projects from Connecticut and New York are highlighted.

Earth Day was founded 51 years ago today. Thousands of people across the nation came together to demand clean air and water and a healthy environment in a movement that by the end of 1970, led to the creation of the US Environmental Protection Agency and a host of environmental laws. In 1990, Earth Day then became an international celebration when 200 million people across 141 countries spoke up together about global environmental issues. To celebrate the week of the 51st Earth Day, below is a list of environmental events happening around the Sound.

STONY BROOK, NY (February 16, 2021): Years ago, during the cold winter months of February and March, streams and rivers around Long Island Sound would be “painted silver” with the arrival of millions of river herring making their way upstream. River herring are diadromous fish, meaning they spend part of their life cycle in saltwater and part in freshwater. Similar to the salmon’s well-known trek upstream, river herrings journey from the ocean into freshwater bodies to reproduce. However, unlike salmon, river herring are not particularly skilled jumpers. So, as Long Island became more urbanized and dams and culverts were constructed in the area, river herring found their path upstream obstructed. This occurrence, in addition to other factors such as pollution and being caught as bycatch, led populations of this ecologically important fish to decline.

To address this issue, the Long Island Sound Study (LISS) and other local environmental management programs have been working for decades to re-open river miles. They do so by collaborating with local stakeholders and landowners to identify dams and culverts for potential removal or by helping fund the construction of “fish ladders,” structures that allow fish to swim over the dam. As of 2006, this work also includes conducting an annual fish survey to identify new potential streams to re-open and to find out if alewives are returning to the 415 river miles that LISS has re-opened in New York and Connecticut since 1998.

Volunteers participate in the survey and help monitor some of these rivers and streams after receiving basic training. This year, amidst Covid-19 restrictions, LISS and its partners are offering their annual monitoring training sessions virtually. The first webinar, open to volunteers in all regions of Long Island, will take place on February 25th at 5:30 pm as part of Community Science LI, an educational webinar series aimed at highlighting local volunteer monitoring efforts and their links to management and research. Volunteers will learn about the ecological importance of river herring, how to identify these traveling fish, and how monitoring makes a difference in local conservation. Additional training webinars are set to occur by region:

The monitoring program is a partnership between LISS, the Peconic Estuary Partnership, the South Shore Estuary Reserve, and the Seatuck Environmental Association.

Estuaries, ecosystems where freshwater and saltwater meet, play very important roles in supporting the ecological, recreational, and economic needs of the communities that surround them. In celebration of these ecosystems, Long Island’s three estuary programs—the Long Island Sound Study, the Peconic Estuary Partnership, and the South Shore Estuary Reserve—partnered to host the third annual Estuary Day event on September 25, 2020.

Estuary Day takes place during National Estuaries Week, which this year ran from September 19-26. Last year, the local outreach event was celebrated at Theodore Roosevelt Park in Oyster Bay, NY, and included informational sessions and booths hosted by local environmental organizations, and a variety of fun educational activities including beach seining and crafts.

This year, Estuary Day went digital with the partnering estuary programs offering webinars to showcase Long Island’s three estuaries, the work being done to protect them, and how the public can get involved in local conservation efforts.

Recording of the LISS webinar Discover LISS: A virtual tour of treasures to explore. Watch on YouTube and click on the video description to access the timestamps and jump to specific parts of the recording.

Long Island Sound Study’s webinar, titled Discover Long Island Sound: A virtual tour of treasures to explore, included a virtual visit to five Stewardship Sites along the North Shore. The tour was led by LISS New York Outreach Coordinator Jimena Perez-Viscasillas (NYSG) and was followed by a Q&A session with LISS Habitat Restoration and Stewardship Coordinator Victoria O’Neill (NYSDEC) and LISS Coordinator Casey Personius (NYSDEC).

The Peconic Estuary Partnership’s and the South Shore Estuary Reserve’s webinars focused on highlighting some of the groups’ current conservation projects in their respective watersheds and on ways for the public to get involved. For access to the video on the South Shore Estuary, contact SSER at [email protected].
