(1993-12)The biogeochemical properties of an extensive bloom (∼250,000 km2) of the coccolithophore, Emiliania huxleyi, in the north east Atlantic Ocean were investigated in June 1991. Satellite (NOAA‐AVHRR) imagery showed that the ...
-
(1993-03)Detailed and accurate emissions inventories are essential for reliable computer dispersion model simulation of the behavior of chemically and radiatively important atmospheric species. Currently, model simulations of the ...
-
(1990-09)Aerosol optical depths and values for the Angstrom exponent, alpha, were retrieved from carefully calibrated sunphotometer measurements which were made during the Global Change Expedition (GCE) of the NOAA ship Mt. Mitchell ...
-
(1987-12)Filter pack and aethalometer systems were successfully used aboard the National Oceanic and Atmospheric Administration WP‐3D and King Air aircraft during the January 1986 intensive field investigation of the Western Atlantic ...
-
(1994-06)The role of the ocean as a sink for anthropogenic carbon dioxide is a subject of intensive investigation and debate. Interest in this process is driven by the need to predict the rate of future increase of atmospheric ...
-
(1993-12)Alkalinity and salinity are linearly correlated in the waters of the most western part of the Mediterranean Sea. Nevertheless, the specific alkalinity of the saltier Mediterranean waters is higher than that of the less ...
-
(1990-09)During the course of the Global Change Expedition/Coordinated Air‐Sea Experiment/Western Atlantic Ocean Experiment, we collected 77 aerosol and 20 precipitation samples over the North Atlantic Ocean; we speciated and ...
-
(1991-06)A simple model is used to examine the way phytoplankton growth influences carbon dioxide concentration in the surface waters of the ocean. The model consists of a one‐dimensional system of two layers, a mixed layer and a ...
-
(1993-03)Conceptual and mathematical models show that annual cycles of phytoplankton biomass are different within different regions of the ocean. The purpose of this manuscript is to use coastal zone color scanner chlorophyll imagery ...
-
(1993-03)In this paper we approach the problem of the origin of organic‐carbon‐rich sediments by using an integrated isotopic and organic geochemical study of the annual productivity/eutrophication cycle in the water column of Lake ...
-
(1993-03)We took measurements of up to 30 gases in Arctic haze and in clean Arctic air. These data were obtained from some 500 flask samples taken on three expeditions of the Arctic Gas and Aerosol Sampling Program (AGASP 1, 2, and ...
-
A seasonal three‐dimensional ecosystem model of nitrogen cycling in the North Atlantic Euphotic Zone(1993-06)A seven‐component upper ocean ecosystem model of nitrogen cycling calibrated with observations at Bermuda Station “S” has been coupled to a three‐dimensional seasonal general circulation model (GCM) of the North Atlantic ...
-
(1993-03)As soils are a likely candidate for the so called missing carbon sink, we explore the possible impact of CO2 fertilization on the global humus inventory. For any given greening‐induced enhancement of plant growth, the ...
-
(1994-06)We conducted an experiment to test explicitly the accuracy of upper ocean sediment trap fluxes using the particle‐reactive radionuclide 234Th (t1/2 = 24.1 days). Two independent VERTEX‐style multitrap arrays were used for ...
-
(1989-03)Overall budgets for nutrient and humus are described for the Baltic Sea as well as for the subsystems, i.e., the Baltic proper, the Bothnian Bay and the Bothnian Sea. The residence times for total phosphorus, total nitrogen, ...
-
(1991-06)As part of the Asian Dust Inputs to the Ocean System (ADIOS) project, atmospheric dust fluxes and primary productivity were monitored during the dusty season (spring) of 1986 at 26°N, 155°W, in the North Pacific Ocean. The ...
-
(1995-06)Dymond et al. (1992) have recently proposed an algorithm to reconstruct paleoproductivity from biogenic Ba (bio‐Ba) accumulation rates in sediments. Their equation is based on sediment trap data which indicate that Corg/bio‐Ba ...
-
(1988-06)Sediment traps deployed at two sites in the equatorial Pacific during and following the 1982‐1983 El Niño southern oscillation (ENSO) demonstrate the biological effects of this event. Biogenic particle fluxes for a site ...
-
(1993-06)The exchange of trace gases and aerosols between the atmosphere and the ocean is an important process in the biogeochemical cycling of both biologically important elements and radiatively important compounds. This exchange ...
-
(1987-12)During the Western Atlantic Ocean Experiment 1986, the National Oceanic and Atmospheric Administration WP‐3D aircraft collected meteorological data and samples of atmospheric gases and aerosols during approximately 40 hours ...
