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 ... -
Controls on Dissolved Silicon Isotopes Along the U.S. GEOTRACES Eastern Pacific Zonal Transect (GP16)
(Global Biogeochemical Cycles, 2020)The distribution of dissolved silicon isotopes (δ30Si) was examined along the U.S. GEOTRACES East Pacific Zonal Transect (GP16) extending from Peru to Tahiti (10°S and 15°S latitude). Surface waters in the subtropical gyre ... -
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 ... -
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 ... -
The Transpolar Drift Influence on the Arctic Ocean Silicon Cycle
(Journal of Geophysical Research: Oceans, 2021-11-03)During most of the year, diatom production in the ice‐covered Central Arctic Ocean (CAO) is limited by light availability and nutrient supply. Therefore, biological production is thought to be generally low, with higher ... -
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 ...
