CARIACO - Carbon Retention in a Colored Ocean

Program Description: Since November 1995, the CARIACO (CArbon Retention In A Colored Ocean) Ocean Time Series program has been studying the relationship between surface primary production (carbon fixation rates by photosynthesis of planktonic algae), regional hydrography, physical forcing variables (such as the wind), and the settling flux of particulate organic carbon in the Cariaco Basin. This tectonic depression, located on the continental shelf of Venezuela (Map), shows marked seasonal and interannual variation in hydrography and primary production induced in part by the regular migration of the Intertropical Convergence Zone (ITCZ).

Year Started: 1995.

Organization Description: This long tern ocean time series joint effort has involved five major Venezuelan institutions and three universities in the U.S. The infrastructure is also a contribution to the International Geosphere-Biosphere Programme (IGBP), Land-Ocean Interactions in the Coastal Zone Program (LOICZ). Collaborators include scientists from South Africa, Denmark, and elsewhere.

Data Description: A CTD (conductivity-temperature-depth meter) is used to measure oxygen, and chlorophyll-a estimates. Data are read out real-time on a computer screen on board the ship as we lower the rosette ensemble to approximately 1,380 m, the bottom of the Cariaco Basin. Water samples are analyzed for various parameters including phytoplankton biomass, dissolved and particulate nutrient and carbon concentration, and primary productivity rates. We also measure total bacterial production. Winds are measured at Santiago Mariño airport (10.9°N 63.96°W) and at the Meteorological station of La Salle (10.54°N, 64.06°W, height 3m).
