Arnone and her colleagues report the concentrations and conditional stability constants of dissolved copper-binding ligands in the Arctic Ocean…
Mete and colleagues used machine learning to predict the global distribution of oceanic barium…
Smith and colleagues determined iodine-129, chlorofluorocarbons and sulfur hexafluoride during three GEOTRACES cruises in the Arctic Ocean.
Using helium and neon as tracers for subglacial meltwater, Krisch and colleagues found that subglacial discharge is a source of dissolved lead.
New research is now shining a light on mercury cycling on the Arctic shelf.
Extensive description of particle concentrations and chlorophyll-a fluorescence distribution along Arctic GEOTRACES sections.
Krisch and colleagues present a flux budget for micronutrient exchange between the Arctic and the North Atlantic Ocean.
They provide an updated mass balance of the Arctic land and ocean mercury cycle.
They synthesized what controls the barium distribution in the Arctic Ocean.
Their findings highlight the importance of the Transpolar Drift in delivering dissolved silica and iron to feed low diatom primary production in the central Arctic Ocean.
This study challenges the paradigm that dissolved aluminium in the bottom waters of the Arctic basins could result from a top-down process.
Earth’s Ice Sheets are known to release significant quantities of lithogenic particles into the ocean every year, but how does this material affect trace metal availability in the ocean?
Brzezinski and his colleagues report on a comprehensive study of the Arctic Ocean silicic acid concentrations and silicon isotopic composition…
The findings demonstrate that glacial retreat and loss of ice-shelves may potentially result in increases in dissolved iron supply to surface waters downstream of large marine terminating glaciers in future.
This study provides one of the first mechanistic explanations for Last Glacial Maximum deep ocean deoxygenation.
Authors demonstrate that the later hypothesis is likely explaining thorium-230-depletion in intermediate layers of the Amundsen basin.
Researchers from the SCRIPPS, the Stockholm Natural Museum and the Mediterranean Institute of Oceanography show the importance of sea ice composition on methylmercury budgets
Whitmore and co-workers demonstrate that the dissolved gallium distribution provide a better water source deconvolution than the nutrient tracers
Using new observations acquired during GEOTRACES Arctic cruises, a refined arctic mercury budget has been established
The spatial distributions and biogeochemical cycling of dissolved Fe (dFe) and dissolved manganese (dMn) across the Arctic Ocean were established during summer and fall 2015. The Canadian GEOTRACES transect extended […]
In the ocean, the residence time of mercury (Hg), is largely driven by two removal mechanisms: evasion to the atmosphere and downward export flux with settling particles. The later was […]
A new study found that freshwater runoff from rivers and continental shelf sediments are bringing significant quantities of carbon and trace elements into parts of the Arctic Ocean
Combining a multiparametric analysis, biogenic and dissolved silicon (Si) isotope data (30Si-bSiO2 and δ30Si-DSi, respectively) in the Arctic Ocean, Liguori and co-workers (2020, see reference below) could unravel the influence […]
A complete review of published and new water column profiles of thorium-230 (230Th) and protactinium-231 (231Pa) concentrations and neodymium (Nd) isotopic compositions collected in the Amerasian Basin of the Arctic […]
Three articles from three cruises highlighted here! Atlantic waters have been recently recognized to play an increasing role in reducing sea-ice extent in the Arctic Ocean at a rate now […]
Data collected during the US Arctic GEOTRACES expedition in 2015 (along GEOTRACES section GN01) were used to estimate the mean residence time of dissolved trace elements (iron-Fe, manganese-Mn, nickel-Ni, cadmium-Cd, […]
Mercury (Hg) concentrations in Canadian Arctic marine mammals were monitored during the last four decades and found to be highly elevated, frequently exceeding toxicity thresholds. Mercury concentrations in marine biota […]
Radium-228 increase in the central Arctic (2007 to 2015), is attributed to stronger wave action on shelves due to a longer ice-free season.
Measurements of radium-228 (228Ra) in the framework of the 2015 U.S. GEOTRACES Arctic Transect (GN01), revealed that the surface water content of this tracer has almost doubled over the last […]
Georgi Laukert and co-workers (2017, see reference below) provide new insights into the sources, distribution and mixing of water masses passing the Fram Strait, the gateway between the Arctic Ocean […]
