Trace Metal Dynamics in Shallow Hydrothermal Plumes at the Kermadec Arc Open
Hydrothermal vents are a source of many trace metals to the oceans. Compared to mid-ocean ridges, hydrothermal vent systems at arcs occur in shallower water depth and are much more diverse in fluid composition, resulting in highly variable…

The distribution of Fe across the shelf of the Western Antarctic Peninsula at the start of the phytoplankton growing season Open
The Western Antarctic Peninsula (WAP) is a rapidly changing region with receding sea-ice cover. This region generally has increased phytoplankton productivity on the continental slope with a decrease observed in off-shelf waters located fu…

Dissolved Cd, Co, Cu, Fe, Mn, Ni, and Zn in the Arctic Ocean Open
During the Polarstern (PS94) expedition, summer 2015, part of the international GEOTRACES program, sources and sinks of dissolved (D) Cd, Co, Cu, Fe, Mn, Ni, and Zn were studied in the central Arctic Ocean. In the Polar Surface Water in wh…

Submarine Hydrothermal Discharge and Fluxes of Dissolved Fe and Mn, and He Isotopes at Brothers Volcano Based on Radium Isotopes Open
Hydrothermal venting is an important transfer process of energy and elements between the Earth’s solid material and the oceans. Compared to mid-ocean-ridge hydrothermal vent fields, those at intra-oceanic island arcs are typically in shall…

Dissolved Trace Metals in the Ross Sea Open
The dissolved (D) trace metals zinc (Zn), cadmium (Cd), cobalt (Co), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), titanium (Ti), lanthanum (La), yttrium (Y), and lead (Pb) were analyzed via ICPMS in samples from the Ross Sea obtain…

Trace metals Ross Sea Phantastic 01 Open
The dissolved trace metals Zn, Cd, Co, Cu, Fe, Mn, Ni, Ti, La, Y and Pb were analysed via ICPMS in samples from the Ross Sea obtained during a cruise between 20 December 2013 and 5 January 2014. The dissolved concentrations of Zn, Cd, Co, …

Effects of iron and light availability on phytoplankton photosynthetic properties in the Ross Sea Open
Waters of the Southern Ocean are characterized by high macronutrient concentrations but limited availability of trace metals and light, often making it difficult for phytoplankton to achieve maximum growth rates. One strategy employed by S…

Evidences of strong sources of DFe and DMn in Ryder Bay, Western Antarctic Peninsula Open
The spatial distribution, biogeochemical cycling and external sources of dissolved iron and dissolved manganese (DFe and DMn) were investigated in Ryder Bay, a small coastal embayment of the West Antarctic Peninsula, during Austral summer …

Fe-Binding Dissolved Organic Ligands in the Oxic and Suboxic Waters of the Black Sea Open
In the oxygen-rich layer of the Black Sea, above the permanent halocline, the Fe and nitrate concentrations are low where fluorescence is relatively high, indicating uptake by phytoplankton. In this study we used ligand exchange adsorptive…
