Demographic data of hydrothermal vent Rimicaris shrimp populations collected on the Mid Atlantic Ridge during the BICOSE 2 cruise (2018)

During the BICOSE 2 cruise in 2018 on board RV Pourquoi Pas ? (Cambon-Bonavita 2018, https://doi.org/10.17600/18000004), alvinocaridid shrimps were sampled at two deep-sea hydrothermal vent fields: TAG and Snake Pit (Mid-Atlantic Ridge). Size, sex, developmental stage and brooding status of 5214 individuals belonging to Rimicaris exoculata and Rimicaris chacei were determined. Samples were preserved in ethanol or in formalin (followed by water washing and storage in ethanol) on board, then brought back to the laboratory for processing. They were analysed at the LEP (Laboratoire Environnement Profond, Ifremer, Centre de Bretagne, France; https://doi.org/10.1101/2021.06.27.450074, and are under review for Marine Ecology Progress Series. The dataset consists of two files: one containing the data itself, and one describing all used terms (measurements or metadata). Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.
