Creator:: Palma, Elbio D., Matano, Ricardo P., and Piola, Alberto R.
Abstract:: This article discusses the results of a suite of numerical simulations of the oceanic circulation in the Southwestern Atlantic Shelf region that are aimed to characterize its mean circulation and seasonal variability and to determine the dynamical mechanisms controlling them. Our experiments indicate that south of 40°S the mean circulation...

Creator:: Gonzalez-Pinzon, Ricardo, Haggerty, Roy, and Myrold, David D.
Abstract:: The use of smart tracers to study hydrologic systems is becoming more widespread. Smart tracers are compounds that irreversibly react in the presence of a process or condition under investigation. Resazurin (Raz) is a smart tracer that undergoes an irreversible reduction to resorufin (Rru) in the presence of cellular metabolic...

Creator:: Sakamoto, Carole M., Karl, David M., Jannasch, Hans W., Bidigare, Robert R., Letelier, Ricardo M., Walz, Peter M., Ryan, John P., Polito, Paulo S., and Johnson, Kenneth S.
Abstract:: Nitrate concentrations, chlorophyll a (Chl a) fluorescence, radiance, salinity, and temperature were measured on the Hawaii Air-Sea Logging Experiment, A Long-Term Oligotrophic Habitat Assessment (HALE ALOHA) mooring located near the Hawaii Ocean Time-Series (HOT) Program’s Station ALOHA (22°45’N; 158°W). Nitrate concentrations were determined with OsmoAnalyzers deployed at depths of 120...

Abstract:: During austral summer 1997, satellite imagery revealed enhanced chlorophyll associated with the Antarctic Polar Front at 170°W. Phytoplankton growth conditions during the early stages of the spring increase were investigated on the Antarctic Environment and Southern Ocean Process Study Survey I cruise using flow cytometry (FCM) and microscopy to characterize...

Creator:: Fetter, Antonio F. and Mantano, Richard P.
Abstract:: This article investigates the origins of the variability of the Malvinas Current (MC) transport using the results of an eddy-permitting ocean general circulation model. First, the dynamical links between the variabilities of the MC and the Antarctic Circumpolar Current (ACC) transports at the Drake Passage are established. Time series analyses...

Creator:: Moore, J. Keith and Abbott, Mark R.
Abstract:: Satellite ocean color data from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) were used to examine distributions of chlorophyll concentration within the Southern Ocean for the period of October 1997 through September 1998. Over most of the Southern Ocean, mean chlorophyll concentrations remained quite low (<0.3-0.4 mg m¯³). Phytoplankton blooms where...
