“Working with CIOR is rewarding because of the involvement and interaction with members of a diverse and multigenerational community. Working together on the boat or on the shore fosters a great team spirit and a feeling of personally making a difference in creating a better environment.”
Ellen Grace and Russell Heath, Eco-volunteers
“As the Scoutmaster of Scouting America Troop 211 on City Island, I have found the City Island Oyster Reef to be an amazing sponsor. Through them, our Scouts have been afforded many opportunities for community service, while also learning about science, ecology, and the environment. Our kids get to work out on the water and be part of a team that is much bigger than themselves and that will have a positive impact on Long Island Sound and our entire ecosystem for years to come.”
Greg Clancy, Scoutmaster
Internships
Join the CIOR Team!
Our internship program plays a crucial role in training the next generation of environmental professionals. Interns are actively involved in various aspects of our work, including water-quality monitoring, shell collection, dive surveys, and data analysis from our oyster research stations. These young professionals gain hands-on experience in environmental science, contributing to our restoration efforts while developing valuable skills in marine conservation, public speaking, and advocacy.
