Hydrography of chromophoric dissolved organic matter in the North Atlantic
The distribution and optical absorption characteristics of chromophoric dissolved organic matter (CDOM) were systematically investigated along three meridional transects in the North Atlantic Ocean and Caribbean Sea conducted as part of the 2003 US CLIVAR/CO2 Repeat Hydrography survey. Hydrographic transects covered in aggregate a latitudinal range of 51 to 621 north along longitudes 201W (line...
متن کاملDissolved Organic Carbon in the North Atlantic Meridional Overturning Circulation
The quantitative role of the Atlantic Meridional Overturning Circulation (AMOC) in dissolved organic carbon (DOC) export is evaluated by combining DOC measurements with observed water mass transports. In the eastern subpolar North Atlantic, both upper and lower limbs of the AMOC transport high-DOC waters. Deep water formation that connects the two limbs of the AMOC results in a high downward ex...
متن کاملDissolved organic carbon in sediments from the eastern North Atlantic
Profiles of dissolved organic carbon (DOC) were measured in the pore water of sediments from 1000, 2000 and 3500 m water depth in the eastern North Atlantic. A net DOC accumulation in the pore waters was observed, which followed closely the zonation of microbial respiration in these sediments. The concentration of pore water DOC in the zone of oxic respiration was elevated relative to that in t...
متن کاملEast-West Distribution of Nutrients and Dissolved Inorganic Carbon in the Northern North Pacific in Autumn
We measured nutrient and dissolved inorganic carbon (DIC) concentrations from west to east across the northern North Pacific Ocean from station K2 to Ocean Station Papa during September and October 2005. At 2000 m depth, silicate levels increased and dissolved oxygen levels decreased from west to east. This trend was attributed to seawater in the layer flowing from west to east in the northern ...
متن کاملNutrient Salts, Inorganic and Organic Carbon Contents in the Waters of the Persian Gulf and the Gulf of Oman
Sea water samples were collected from 32 stations in the southern part of the Persian Gulf and the Gulf of Oman during winter of 1987. Surface water of the Persian Gulf exhibited wide range and higher values of salinity (37.15-43.95, mean 40.02%) compared with lower values and narrow range (36.58-36.95, mean 36.74%) in the Gulf of Oman. Surface salinity did not reflect any significant relations...
