Marine Biology Société Jersiaise

Since 1949 the Marine Biology Section (MBS) of the Société Jersiaise has been making practical studies of Jersey’s seashore.


This is no easy task as the island has a 12 metre tidal range which, at low water, can increase the area of the island by over a third.


The MBS is a small group of marine life enthusiasts who enjoy making causal and scientific studies along Jersey’s magnificent seashore. As well as practical things such as rock pooling and diving, we also have a series of projects which collect data that helps us to better understand our marine envrionment and, in some cases, argue for its conservation.


The MBS is a mix of people which inlcudes everyone from professional marine biologists to casual beachcombers. We are always keen to hear from anyone with an interest in Jersey’s marine environment.
