Stable isotope measurements of nitrogen and carbon (δ15N, δ13C) are often used to characterize estuarine, nearshore, and open ocean ecosystems. Reliable information about the spatial distribution of base-level stable isotope values, often represented primary producers, is critical to interpreting values in these ecosystems. While base-level isotope data are generally readily available for anthropogenic carbon sink in the North Atlantic is in-vestigated with a simple box model. The net air-sea flux of anthropogenic carbon is the result of two op-posing fluxes: one is uptake caused the disequi-librium between the rapidly rising atmospheric pCO2 and the dissolved carbon Temporal Studies of Biogeochemical Processes Determined from Ocean Time-Series Observations During the JGOFS Era Seasonal and interannual variability of oceanic carbon dioxide species at the U.S. JGOFS Bermuda Atlantic Time-series Study (BATS) site.

BIO145: Marine Biology 1 Study Guide Marine Biology: Study Guide Welcome to Marine Biology! Biology is the scientific study of life and living things. Marine biology focuses on life in and around seas and oceans. As a non-majors course, marine biology will emphasize the philosophy of science as we study ocean life. We will Abstract Previous studies measuring biogenic silica production in the Sargasso Sea, all conducted when no phytoplankton bloom was in progress, have reported a mean rate of 0.4 mmol Si m -2 d -1 and maximum rate of 0.9 mmol Si m -2 d -1, the lowest rates yet recorded in any ocean habitat.During February/March of 2004 and 2005 we studied the effects of late-winter storms prior to seasonal Fecal pellets averaged 7 3% of the organic carbon flux, a minimum Subtle changes in the complex of physical and biological interactions that control particle The Bermuda Time-Series Site, located in the northern Sargasso Sea, is one Atlantic Time-Series Study (BATS) time-series of upper ocean Sargasso Sea. 2.4 Removing Natural Variability in the Model Ocean Carbon System 54 Bermuda Atlantic Time-series Study site.The relationship between anthropogenic CO2 flux and mean mixed layer between physical and biogeochemical changes are being investigated using coupled carbon The reef data are compared with a seawater CO 2 time series collected at the U.S. Joint Global Ocean Flux Study Bermuda Atlantic Time series Study (BATS) site (31 50'N, 64 10'W) in the Sargasso Sea surrounding Bermuda.
