What is it about?

Ostracoda (crustacea) are an important part of the Mediterranean benthic fauna. In the fossil record, several ostracod associations and species have been recognised as typical of CO2 rich marine environments. We have studied bottom sediment samples from a pockmark area and from an area just outside it, to check if there were some differences. We have found out that the high CO2 level is a crucial threshold for ostracods life.

Why is it important?

It is the first time that a study compares ostracod communities inside and outside a pockmark area


Further studies in seepage and gas rich areas are important to correctly understand the adaptation mechanisms of these crustaceans but also to correctly interpret the paleontological record.
