The National Aeronautics and Space Administration/ Goddard Flight Center's Nimbus Project Office, in collaboration with the NASA/GSFC Data Computing Division, Laboratory for Oceans University of Miami/Rosenstiel School Marine Atmospheric Science, have undertaken to process all data acquired by Coastal Zone Color Scanner (CZCS) Earth‐gridded geophysical values provide ready access products [ Esaias et al ., 1986]. An end‐to‐end system utilizing recent advances base management both digital...
Large areas of elevated phytoplankton pigment concentrations were observed using CZCS satellite data in the Weddell Sea marginal ice zone and adjacent regions during austral summer‐autumn transition. The study was made conjunction with situ observations levels derived from passive microwave observations. area investigation includes eastern western parts part Antarctic Peninsula. Phytoplankton blooms, about 200 km wide extending several hundred kilometers along edge, observed. Higher values...
The number of diatom valves and fragments per gram surface sediment in the Atlantic Ocean accurately reflects abundance overlying waters, without any evidence significant lateral drift during settling to sea bottom. distribution pattern resting spores is similar that for whole fragmented valves. Fresh water diatoms opal phytoliths are abundant sediments off west coast Africa where they have been deposited by Trade Winds. Despite relatively small core tops analyzed, patterns exhibit striking...
Abstract The equatorial North Atlantic Ocean (NAO) is a nutrient‐limited ecosystem that relies on the deposition of long‐range transported iron (Fe)‐containing aerosols to stimulate primary productivity. Using microscopy, we characterized supermicron and supercoarse mode African western NAO in boreal winter/spring. We detected three particle types including dust, biological aerosol particles, freshwater diatoms (FDs). FDs contained 4% Fe by weight due surficial dust inclusions may be...
Coastal Zone Color Scanner (CZCS) images of the eastern Bering Sea between April 27 and July 22, 1980, were analyzed in a study biological response system to 1000‐km retreat ice edge across shelf subsequent establishment highly stratified water column characteristic spring early summer. Images from Norton Sound area showed seasonal changes both an bloom near sound Yukon River sediment plume inside sound. Three revealed details several stages classic development over which typically begins...
The Barents Sea is a productive, shallow, high-latitude marine ecosystem with complex hydrographic conditions. Zonal bands defined by coastal current. North Atlantic Water, the Polar Front, and seasonally variable marginal ice edge zone create meridional zonation of during spring-summer transition. features reveal themselves in satellite imagery high-resolution (vertical horizontal) physical-optical-biological sampling. Surprisingly, long-term (7-year) mean Coastal Zone Color Scanner (CZCS)...
Nimbus-7 Coastal Zone Color Scanner (CZCS) data were used to compute spatial distribution of surface phytoplankton pigments in coastal and offshore waters near Iceland April 1979. The standard CZCS processing algorithms applied a limited evaluation their accuracy was conducted. This utilized situ measurements from cruise the area clear water radiance concept. Initial results appear confirm that at these moderately high latitudes exhibit similar validation studies conducted mid Atlantic bight.
