2. Trace metal data Regenerating chemical database Load data from CSIR Durban
3. Regular data loading: Surface weather data CTD 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.
