AMT30 (DY157) CTD profiles (pressure, temperature, salinity, potential temperature, density, fluorescence, attenuation, transmittance, downwelling and upwelling PAR, dissolved oxygen concentration) calibrated and binned to 1 dbar, from the Atlantic Meridional Transect between February-March 2023.

This dataset consists of 57 CTD profiles collected during the Atlantic Meridional Transect programme cruise 30 (AMT30 DY157) between 20th February 2023 and 30th March 2023. The cruise track between the Falkland Islands and the UK via Cape Verde, passed through both north and south Atlantic gyres. This dataset contributes to the AMT time-series of core oceanographic measurements along a north-south transect of the Atlantic Ocean. The profile down casts were processed on-board and binned to 1 dbar. Calibrations were applied to salinity as described in the post cruise report. Fluorescence has not been calibrated for this dataset.
