Field trips have been conducted from February 2019 to May 2020 in Poe lagoon (South Province - New Caledonia) to characterize its hydrodynamic processes and functionning. This shallow lagoon belongs to a wider area which has been registered at the UNESCO World Natural Heritage list in 2008 and has experienced recently beaching of seaweed (ulva sp.). A dedicated project (ELADE) has been launched to investigate paths of enrichment of this lagoon. This dataset belongs to the Hydrodynamics Task of this multidisciplinary project. Several moorings (~ 15) have been placed for observations of currents, temperature, pressure and  salinity dynamics during 2 legs (Feb. to May 2019 ; July-August 2019). During this field period, one major atmospheric event happened in February 2019 : OMA cyclone. From september 2019 to may 2020, a single station (temperature, salinity, pressure) has been kept in the area of maximum ulva biomass.

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).
