Calculation of UV attenuation and colored dissolved organic matter absorption spectra from measurements of ocean color
(American Geophysical Union, Washington, DC, 2003-09)No abstract available. -
The carbon budget of the North Sea
(2005)A carbon budget has been established for the North Sea, a shelf sea on the NW European continental shelf. The carbon exchange fluxes with the North Atlantic Ocean dominate the gross carbon budget. The net carbon budget ... -
Carbon cycle research after Kyoto
(1999-04)Recent progress in research of the global carbon cycle is reviewed and research needs for the immediate future are discussed, in light of the challenge posed to society to come to grips with the problem of man-made climate ... -
Carbon cycling in the Arctic Archipelago: the export of Pacific carbon to the North Atlantic
(European Geosciences Union, 2009-01)The Arctic Ocean is expected to be disproportionately sensitive to climatic changes, and is thought to be an area where such changes might be detected. The Arctic hydrological cycle is influenced by: runoff and precipitation, ... -
Carbon disulfide in the North Atlantic and Pacific Oceans
(American Geophysical Union, Washington, DC, 1999-03)No abstract available. -
Changes in buoyancy and chemical composition during growth of a coastal marine diatom: Ecological and biogeochemical consequences
(1995)Growth and sinking of the coastal marine diatom Thalassiosira weissflogii was studied during experiments in a 2.1 m tall water column. Under nutrient-replete conditions, T. weissflogii grew rapidly in the upper layer of ... -
Composite global emissions of reactive chlorine from anthropogenic and natural sources: Reactive Chlorine Emissions Inventory
(1999-04)Emission inventories for major reactive tropospheric Cl species (particulate Cl, HCl, ClNO2, CH3Cl, CHCl3, CH3CCl3, C2Cl4, C2HCl3, CH2Cl2 and CHClF2) were integrated across source types (terrestrial biogenic and oceanic ... -
The continent-ocean crustal transition across the southwest Greenland margin
(1994-05/10)The complete crustal transition across the nonvolcanic, southwest Greenland continental margin of the Labrador Sea is examined using wide-angle and coincident vertical-incidence seismic profiles. Six ocean bottom seismometers ... -
Contrasting biogeochemistry of nitrogen in the Atlantic and Pacific Oxygen Minimum Zones
(2012)We present new data for the stable isotope ratio of inorganic nitrogen species from the contrasting oxygen minimum zones (OMZs) of the Eastern Tropical North Atlantic, south of Cape Verde, and the Eastern Tropical South ... -
Controls of the surface water partial pressure of CO2 in the North Sea
(2005)The seasonal variability of the partial pressure of CO2 (pCO(2)) has been investigated in the North Sea, a northwest European shelf sea. Based on a seasonal and high spatial resolution data set the main controlling factors ... -
Crustal structure of the Labrador Sea conjugate margin and implications for the formation of nonvolcanic continental margins
(1995-12)Wide-angle seismic studies have determined the detailed velocity structure along a 350-km-long profile across the Labrador margin. Combination of this model with a previously published cross section for the southwestern ... -
Crustal structure of the northern Nova Scotia rifted continental margin (eastern Canada)
(2004-09)[ 1] The Nova Scotia continental margin off eastern Canada marks a transition from a volcanic to a nonvolcanic style of rifting. The northern ( nonvolcanic) segment of the margin was studied by a 490-km-long refraction ... -
Crustal structure of the ocean-continent transition at Flemish Cap: Seismic refraction results
(2003-11)[1] We conducted a seismic refraction experiment across Flemish Cap and into the deep basin east of Newfoundland, Canada, and developed a velocity model for the crust and mantle from forward and inverse modeling of data ... -
Current CaCO3 dissolution at the seafloor caused by anthropogenic CO2
(PNAS, 2018-10-29)Oceanic uptake of anthropogenic CO2 leads to decreased pH, carbonate ion concentration, and saturation state with respect to CaCO3 minerals, causing increased dissolution of these minerals at the deep seafloor. This ... -
Deep structure of the ocean-continent transition in the southern Iberia Abyssal Plain from seismic refraction profiles: Ocean Drilling Program (Legs 149 and 173) transect
(1999-04)We present a wide-angle seismic refraction study of an 80x40 km region of the southern Iberia Abyssal Plain, south of Galicia Bank. An intersecting grid of two E-W and four NS wide-angle reflection/refraction profiles is ... -
Deep structure of the ocean-continent transition in the southern Iberia Abyssal Plain from seismic refraction profiles: The IAM-9 transect at 40 degrees 20 ' N
(2000-03)We present a crust and mantle velocity structure for the West Iberia passive continental margin derived from a 320-km-long wide-angle seismic profile acquired in the southern Iberia Abyssal Plain. We observe a 170-km-wide ... -
A description of water types on the Mackenzie Shelf of the Beaufort Sea during winter
(1992)For a number of years during the 1980s, observations of the physical and chemical properties of seawater in the southeastern Beaufort Sea have been acquired in late winter. The most complete data set, from 1987, has been ... -

The detection of coastal-trapped waves
(1991-02/15)The authors outline a simple method for estimating the cross-spectral matrix of coastal-trapped wave amplitudes, A, from a set of oceanographic observations. Specifically, they propose that A may be estimated by ... -
Dichloromethane in North Atlantic waters
(2004-09)[1] Dichloromethane is an atmospheric trace gas that has a tropospheric lifetime on the order of 5 months and has major anthropogenic sources. Evidence has been presented for an oceanic source. This paper reports measurements ...
