Environmental risk of nickel in aquatic Arctic ecosystems ...
In marine environments, median Ni concentrations in snow, water, and sediment samples were 0.19 μg L −1, 0.26 μg L −1, and 40 mg Ni kg −1 respectively, with relatively small variation across the Arctic . Overall, literature data provided no evidence of elevated Ni exposure in Arctic marine environments.

Sea-ice microbial communities in the central Arctic
2021-6-14 · The Arctic Ocean is more susceptible to ocean acidi fication than other marine environments due to its weaker buffering capacity, while its cold surface water with relatively low salinity promotes atmospheric CO 2 uptake. We studied how sea-ice microbial communities in the central Arctic Ocean may be affected by changes in the carbonate

2021-10-15 · The ICE6 sediment is characterized by inter-bedding of dark brownish and yellowish layers, indicative of interglacial/glacial environments in the central Arctic Ocean (Polyak et al., 2009; Stein et al., 2010). Samples were taken at 2-cm intervals from the total core length of 426 cm for further analysis.

As with most global NWP models, the MetUM does not have a prognostic aerosol/cloud scheme but uses a constant CCN concentration of 100 cm −3 over all marine environments. It is therefore unable to represent the low CCN number concentrations and the rapid variations in concentration frequently observed in the central Arctic during late summer.

2021-11-8 · Cloud liquid water path (LWP) is an important control on cloud radiative properties, particularly in the Arctic, where clouds play a central role in the surface energy budget. Therefore, understanding how aerosols may alter cloud LWP is important, especially as aerosol sources such as industry and shipping move further north in a warming Arctic.
