Long Island Sound: What lives between the tides?

Our GEMS grade five marine scientists explored the sandy and rocky beaches of Long Island Sound during the past week to investigate what life lives between the tides! Students donned waders and safety gear and used a 30-foot seine net to collect specimens and observe them in a beach laboratory set-up by teachers and then release most of the specimens back into the sea.

In addition students had the opportunity to use ipads to collect images of the coastline environment. Students also sifted beach samples using special geologist tools to make observations and record what makes up the beach at Hammonasset State Park.

Most exciting was the almost 1,000 crabs collected during the day on the rocky beach! Students became experts at measuring sizes, assigning gender, sorting and counting an invasive species, the Asian or Japanese Shore crab. Data will be compared to crab data collected over the past several years and will be used to assess any changes when GEMS student scientists return to Hammonasset in the spring!
