Distribution of COz species, estimates of net community production, and air-sea COz exchange in the Ross Sea polynya
Measurements of surface total carbon dioxide (TCO2) , alkalinity, and calculated pCO2, along with water column nutrients and hydrography, were made on two cruises to the Ross Sea polynya (NBP 94-6, November-December 1994 and NBP 95-8, December 1995 to January 1996). The polynya experiences an intense phytoplankton bloom during a short period of open water conditions from mid-December to midFebr...
متن کاملNet community production in the northeastern Chukchi Sea
and particulate organic carbon (POC) and particulate organic nitrogen (PON) were measured during the spring and summer of 2004 and compared to similar observations taken in 2002. Distinctive differences in hydrographic conditions were observed between these two years, allowing us to consider several factors that could impact NCP and carbon cycling in both the Chukchi Shelf and the adjacent Cana...
متن کاملBiogeochemical regimes, net community production and carbon export in the Ross Sea, Antarctica
The net community production (NCP) of the Ross Sea, from the early austral spring (mid-October) to the austral summer (mid-February), has been estimated from the seasonal drawdown of CO 2 concentrations integrated over the top 100m of the water column. The de"cits in nutrients and CO 2 indicate three distinct biogeochemical regimes. The regime in the southwestern Ross Sea (Region I) had relativ...
متن کاملOcean carbon cycling in the Indian Ocean: 2. Estimates of net community production
[1] The spatiotemporal variability of ocean carbon cycling and air-sea CO2 exchange in the Indian Ocean was examined using inorganic carbon data collected as part of the World Ocean Circulation Experiment (WOCE) cruises in 1995. Several carbon mass balance approaches were used to estimate rates of net community production (NCP) in the Indian Ocean. Carbon transports into and out of the Indian O...
متن کاملEvaluation of satellite and reanalysis‐based global net surface energy flux and uncertainty estimates
The net surface energy flux is central to the climate system yet observational limitations lead to substantial uncertainty. A combination of satellite-derived radiative fluxes at the top of atmosphere adjusted using the latest estimation of the net heat uptake of the Earth system, and the atmospheric energy tendencies and transports from the ERA-Interim reanalysis are used to estimate surface e...
