Dissolved gallium in the open ocean

  title={Dissolved gallium in the open ocean},
  author={Kristin J. Orians and Kenneth W. Bruland},
Greater understanding of the distributions and biogeochemical cycling of trace metals in the oceans has recently been attained due largely to advances in analytical chemistry and in trace metal sampling. We present here the first oceanographically consistent distribution of dissolved gallium in the open ocean, with concentrations 1–2 orders of magnitude lower than those reported previously1–3. The distribution of dissolved gallium is complex, indicating multiple sources and removal by… Expand
Dissolved titanium in the open ocean
VERY little is known about the marine geochemistry of dissolved titanium, mainly because of the difficulties involved in the analysis of this highly refractory element at the extremely low levelsExpand
The marine geochemistry of dissolved gallium: A comparison with dissolved aluminum
Abstract Dissolved Ga concentrations in the Pacific Ocean range from 2 to 30 picomolar: they are low in surface waters (2–12 pM), with a subsurface maximum at 150–300 m (6–17 pM), a mid-depth minimumExpand
Distribution patterns of the elements in the ocean: A synthesis
The observed partition patterns of elements between a marine solid phase (e.g., pelagic clays, deep sea manganese nodules, seamount manganese crusts, and plankton) and seawater can be, to the firstExpand
A fresh look at element distribution in the North Pacific Ocean
Several excellent and thoughtful reviews on the chemical composition of seawater were published in the early 1980s. In particular, Bruland (1983) discussed speciation of various elements, BroeckerExpand
Vertical mercury distributions in the oceans
The vertical distribution of mercury (Hg) was determined at coastal and open ocean sites in the northwest Atlantic and Pacific Oceans. Reliable and diagnostic Hg distributions were obtained,Expand
Dissolved gallium in the Atlantic Ocean
Abstract Gallium is geochemically similar to aluminum, though less reactive. As such, gallium is potentially useful to resolve questions about the aluminum distribution. Dissolved gallium data fromExpand
Dissolved gallium in the northwest Pacific and the south and central Atlantic Oceans: Implications for aeolian Fe input and a reconsideration of profiles
The distribution of dissolved gallium, a less-reactive analogue of aluminum, has the potential to reveal information about the averaged dust input to the surface ocean and to complement studies usingExpand
The effect of surface reactions on the relative abundances of trace metals in deep-ocean water
Abstract An improved general approach for estimating the relative abundances of trace metals in aquatic systems is introduced. It is proposed that the relative concentrations of trace metals inExpand
Dissolved gallium in the Beaufort Sea of the Western Arctic Ocean: A GEOTRACES cruise in the International Polar Year
Abstract Dissolved gallium (Ga) concentrations are presented from the Beaufort Sea, representing the first reported values of Ga in the Arctic Ocean. Profiles of dissolved Ga in this region reflectExpand
Reactive trace metals in the stratified central North Pacific
Abstract Vertical concentration profiles of the dissolved and suspended particulate phases were determined for a suite of reactive trace metals, Al, Fe, Mn, Zn, and Cd, during summertime at a stationExpand


The distribution of dissolved copper in the eastern Atlantic Ocean
Abstract Dissolved copper concentrations at five stations in the eastern Atlantic between 20 and 24°N are presented. The metal is depleted in surface waters with concentrations ranging from 1.1 toExpand

The distribution of dissolved aluminum in open ocean waters is probably controlled by the solution of aluminum from atmospherically derived particles and bottom sediments balanced against scavengingExpand
The biogeochemistry of aluminum in the Pacific Ocean
Abstract Vertical distributions and horizontal surface transects of dissolved and particulate Al at several locations in the Pacific Ocean are presented here. Concentrations of dissolved Al in theExpand
The contrasting biogeochemistry of iron and manganese in the Pacific Ocean
Abstract Vertical and horizontal distributions of dissolved and suspended particulate Fe and Mn, and vertical fluxes of these metals (obtained with sediment traps) were determined throughout theExpand
The distribution of dissolved copper in the Pacific
Abstract The general form of Cu-depth profiles is unique. In the central North Pacific, values decrease from a surface maximum of about 3 nmol/kg to 1.5 nmol/kg in the upper thermocline. Below aboutExpand
Lead concentrations in the northeast Pacific: evidence for global anthropogenic perturbations
Lead concentrations were determined by isotope dilution mass spectrometry in 34 surface- and deep-water samples collected in the northeast Pacific between Hawaii and California and off the CaliforniaExpand
Dissolved aluminium in the central North Pacific
Aluminium is the most abundant metallic element in the Earth's crust (8.23% by weight)1, yet little is known about its oceanic distribution. Published data sets concerning aluminium in sea-water2 areExpand
The distribution of iron in the Northwest Atlantic
Abstract Samples from eleven stations in the Sargasso Sea, Slope Water, and continental shelf water of the Northwest Atlantic have been analyzed for total iron by atomic absorption spectrophotometry.Expand
Oceanographic distributions of cadmium, zinc, nickel, and copper in the North Pacific
Abstract Vertical profiles of Cd, Zn, Ni, and Cu have been determined at three stations in the North Pacific and in the surface waters on a transect from Hawaii to Monterey, California. TheExpand
Distribution of Be, Al, Se and Bi in the surface waters of the western North Atlantic and Caribbean
Abstract The mixed layer distributions of several trace elements have been determined along a detailed transect from Rhode Island to the Panama Canal. When taken together with a new and existingExpand
