Welcome to Cedar Island Marina Research Laboratory! 

Please Click Here for Our Summer Camp Program
Marine Biology Education Program

Cedar Island Marina Research Laboratory, a private marine research lab founded by Cedar Island Marina, Inc. in 1988, addresses marine issues in Clinton Harbor and the remainder of Long Island Sound. We regularly perform research studies including water quality, aquaculture, finfish, invertebrate and invasive species ecology. Specific study organisms include, but are not limited to: the Northern Star Coral (Astrangia poculata), Winter Flounder (Pseudopleuronectes americanus), Asian Shore Crab (Hemigrapsus sanguineus), Green Crab (Carcinus maenas) and Blue Crab (Callinectes sapidus).

We have been recognized not only for our scientific research at conferences around the country, but also for our environmental educational programs which have reached over 55,000 children and adults. We offer both Guided Field Explorations at Hammonasset State Park and Traveling Touch Tanks where we bring Long Island Sound to you!

Cedar Island Marina Research Laboratory has collaborated, and authored studies, with organizations such as the Department of Agriculture Bureau of Aquaculture, National Marine Fisheries Service, U.S. Fish and Wildlife Service, Connecticut Department of Environmental and Energy Protection, Southern Connecticut State University, University of Connecticut Sea Grant, as well as many other public and private entities.

2017 Marine Biology Summer Program

We are excited to announce the details to our 2017 Marine Biology Summer Program! 

The program will run from June 19th to August 25th and will be $400 per camper per week. The program will run from 9-3 daily. 

What's New?

In addition to the number of marine science activities that are done throughout our program, this year participants will assist in real research! CIM Research Lab will be conducting a small scale bio-assessment of the marina by collecting, identifying, and quantifying different types of plankton by looking through a compund microscope and chambered slide.

We are hoping to make this our best year yet and invite you to join us! Register by clicking on the "Marine Biology Camp" tab followed by the "Camp Registration" tab.

See you this summer! 

  • Summer 2018 Marine Biology Educational Program Dates

  • January 12, 2018

  • Is It Summer Yet? 

    The animals in Long Island Sound are here to stay all year round, and so are we! Our team has been working hard to reflect over the past summer and prepare for the next one. We are happy to annouce our Marine Biology Summer Program dates for 2018! Although last year's experiences with our programs will be difficult to top, we added some new components for participants to look forward to! We will be taking a closer look into the seaweed species of Long Island Sound, believe it or not, they are quite beautiful! We will also be continuing with our biodiversity studies that participants will help with!

    Check out our page here for information on dates, prices, and more! 

    See you this season!
