Title of dataset | Nutrient data collected during the ABRACOS 1 and 2 surveys performed along the northeast Brazilian continental shelf, slope and open ocean |
Narrative summary of dataset | Samples were collected during the “Acoustics along the BRAzilian COaSt (ABRACOS)” oceanographic campaigns, carried out in Austral spring (30 August - 20 September of 2015 - ABRAÇOS1; Bertrand, 2015) and fall (9 April - 9 May of 2017 - ABRAÇOS 2; Bertrand, 2017) on board the French R/V ANTEA. Spring 2015 and fall 2017 are representative of canonical spring and fall conditions in terms of thermohaline structure and currents dynamics (Assunção et al., 2020; Dossa et al., 2021). Nutrients (nitrite NO2, nitrate NO3, phosphate PO4 and silicate Si(OH)4) have been determined on seawater samples collected using Niskin bottles at different depths during the cruise. Up to 12 samples were collected at each station, depending on the station depth. Samples were collected and "pasteurised" (ie heated at 80C for 2h30 in an oven) to ensure their stability until the analysis was performed at the laboratory. The nutrients analysis has been achieved using the classical colorimetric method (Technicon analyzer). 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. |
