Pressure and temperature records from the proximity of the Rainbow hydrothermal site.  The record spans from 8th to 26th May 2022. Data were acquired with an RBR Duet pressure sensor lent by PNIO. The pressure sensors was deployed on a broad band OBS (BBOBS) from the INSU national OBS parc at IPGP. Datafiles includes the full raw data file, and a file with only the record at the seafloor, after removing the ascent and the descent of the instrument, attached to the BBOBS) The seafloor position of the OBSs is: 36.23544°N, 36.91036°W, 2505 m waterdepth (~2538 m average depth recorded in this record). Important Note: This submission has been initially submitted to SEAscieNtific 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.

Current meter Nortek Aquadopp data. Data for 2 current meter deployments of NORTEK Aquadopp instruments at the Rainbow Massif. Instruments where kindly provided by the Parc National d'Instrumentation Océanographique de l'INSU. Data is provided in 2 sets of files, corresponding to deployments AES_C01 and AES_C02. The instruments where installed in a broadband OBS (BBOBS) from the INSU OBS National Park.  Deployment AES_C02 includes two lowerings (see information below, indicated as deployments AES_C02A and AES_C02B). AES_C01 with current meter serial number : A6L6094 (head) AQD11097 (Hardware), deployed on BB03 with deployment AES_B01_BB3. Bottom position: 36.23544°N, 33.91036°W, 2505 m waterdepth. AES_C02_A with current meter serial number : A6L6127 (head) AQD11247 (Hardware), deployed on BB02, deployment AES_B03_BB02. Bottom position: 36.22233°N, 33.87996°W, 1950m waterdepth. AES_C02_B with current meter serial number : A6L6127 (head) AQD11247 (Hardware), deployed on BB02, deployment AES_B06_BB02. Bottom position: 36.2020833°N, 33.8118833°W, 2557m waterdepth.
