Description

The dataset contains 7 observational subsets collected in the South Atlantic Basin (45S~0N), including 4 cruise/float individual profiles datasets and 2 gridded datasets. Specifically:

(1) cruise/float individual profiles datasets
•    SAMBA-MSM60 cruises (Filename: SAMBA-MSM60.zip)
•    SAMBA-west (SAM02-SAM18) cruises (Filename: SAMBA-West.zip)
•    GO-SHIP A09, A10 cruises (Filename: GO-SHIP.zip)
•     South Atlantic Individual Argo profiles (Filename: Argo_T_S_float.zip)

•     GoodHope cruises (Filename: GoodHope.zip)

•     SAMBA-East cruises (Filename: SAMBA-East.zip)

(2) Gridded products
•    South Atlantic IAP monthly gridded products (0-6000m)  (Filename: IAP_gridded_product.zip)
•    South Atlantic SIO Argo gridded products (0-2000m) (Filename: SIO-Argo.zip)

The README file could be found in each subset.

This dataset is affiliated with the Delivery 5.3 (D5.3) of the EU OCEAN:ICE project.
