2. Trace metal dataRegenerating chemical databaseLoad data from CSIR Durban

3. Regular data loading:Surface weather dataCTD data (Namibia, MCM, France,

Germany)GODAR data (WDC-Oceanography)AWS data (MCM)ADCP (ACEP)Ship-borne currents (CSIR)

4. Possible expansions: Plankton data (BCLME) Involvement with SAEON Satellite data of suitable format

(BCLME/SAEON) Production of environmental indices (BCLME)

– indices to indicate the status of certain parameters (within a geographical area, depth interval, using algorithms defined by a user community)

– Can be computed at given time intervals (e.g. quarterly), or for given cruises, etc.
