CAVASSOO database: surface pCO2 in the Atlantic ocean

1
CAVASSOO database surface pCO2 in the Atlantic
ocean

• 204 cruises
• 450,000 pCO2 measurements
• Other parameters temperature, salinity, TCO2,
  alkalinity, pH, oxygen, wind, nitrate, nitrite,
  phosphate, silicate (surface measurements)
• And CFCs, NH4 for bottle measurements

• R/V Nuka Arctica (Bergen), M/V Falstaff (Kiel),
• R/V Hesperides (Vigo),
• M/V Santa Lucia-M/V Santa Maria (UEA)
• pCO2 underway, SST, S, nutrients
• AMT cruises 2003-2006, twice a year, research
  cruises
• RRS James Clark Ross (previous AMT 1995-2000)
• pCO2 , SST, S underway

Relational database

• Information stored
• cruise information (dates, track, vessel, status
  of data, comments)
• investigators
• underway and bottle data
• Access
• Commands using Structured Query Language (SQL)
• Development of a web interface for online access
• Public data sent to British Oceanographic Data
  Centre (BODC) at the end of CAVASSOO (2003) and
  AMT.
