Arctic – Atlantic Exchange of the Dissolved Micronutrients Iron, Manganese, Cobalt, Nickel, Copper and Zinc With a Focus on Fram Strait
; ; ; ; ; ; ; ; ; ; ; ; (Global Biogeochemical Cycles, 2022-05-16)
The Arctic Ocean is considered a source of micronutrients to the Nordic Seas and the North Atlantic Ocean through the gateway of Fram Strait (FS). However, there is a paucity of trace element data from across the Arctic ... -
Authigenic Formation of Clay Minerals in the Abyssal North Pacific
; ; ; ; ; ; ; ; ; ; (Global Biogeochemical Cycles, 2022-11-10)
Present estimates of the biogeochemical cycles of calcium, strontium, and potassium in the ocean reveal large imbalances between known input and output fluxes. Using pore fluid, incubation, and solid sediment data from ... -
Constraining Global Marine Iron Sources and Ligand‐Mediated Scavenging Fluxes With GEOTRACES Dissolved Iron Measurements in an Ocean Biogeochemical Model
; ; ; ; ; ; ; ; (Global Biogeochemical Cycles, 2021-08-09)
Iron is a key micronutrient controlling phytoplankton growth in vast regions of the global ocean. Despite its importance, uncertainties remain high regarding external iron source fluxes and internal cycling on a global ... -
Dissolved, Labile, and Total Particulate Trace Metal Dynamics on the Northeast Greenland Shelf
;; ; ; ; ; ; ; (Global Biogeochemical Cycles, 2022-11-28)
We present high‐resolution profiles of dissolved, labile, and total particulate trace metals (TMs) on the Northeast Greenland shelf from GEOTRACES cruise GN05 in August 2016. Combined with radium isotopes, stable oxygen ... -
El Niño-Driven Oxygenation Impacts Peruvian Shelf Iron Supply to the South Pacific Ocean
; ; ; ; ; ; (Geophysical Research Letters, 2020)
Upwelling ocean currents associated with oxygen minimum zones (OMZs) supply nutrients fuelling intense marine productivity. Perturbations in the extent and intensity of OMZs are projected in the future, but it is currently ... -
Quantifying Ice‐Sheet Derived Lead (Pb) Fluxes to the Ocean; A Case Study at Nioghalvfjerdsbræ
; ; ; ; ; (Geophysical Research Letters, 2022-11-07)
Concentrations of the toxic element lead (Pb) are elevated in seawater due to historical emissions. While anthropogenic atmospheric emissions are the dominant source of dissolved Pb (dPb) to the Atlantic Ocean, evidence ... -
Sediment Release in the Benguela Upwelling System Dominates Trace Metal Input to the Shelf and Eastern South Atlantic Ocean
; ; ; ; ; (Global Biogeochemical Cycles, 2022-09-25)
Upwelling of subsurface waters injects macronutrients (fixed N, P, and Si) and micronutrient trace metals (TMs) into surface waters supporting elevated primary production in Eastern Boundary Upwelling Regions. The eastern ... -
Trace Element Biogeochemistry in the High‐Latitude North Atlantic Ocean: Seasonal Variations and Volcanic Inputs
; Steigenberger, Sebastian; ; ; ; ; ; ; ; ; Moore, C. Mark (Global Biogeochemical Cycles, 2021-03-15)
We present dissolved and total dissolvable trace elements for spring and summer cruises in 2010 in the high‐latitude North Atlantic. Surface and full depth data are provided for Al, Cd, Co, Cu, Mn, Ni, Pb, and Zn in the ... -
Variability in the Concentration of Lithium in the Indo‐Pacific Ocean
; ; ; ; ; ; (Global Biogeochemical Cycles, 2022-06-22)
Lithium has limited biological activity and can readily replace aluminium, magnesium and iron ions in aluminosilicates, making it a proxy for the inorganic silicate cycle and its potential link to the carbon cycle. Data ...
