DOI: 10.1029/2019gl084012
Abstract: Structural glaci‐geological processes can entrain basal sediment into ice, leading to its transportation and deposition downstream. Sediments potentially rich in essential nutrients, like silica and iron, can thus be transferred from continental sources to the… read more here.

DOI: 10.1029/2020gl091835
Abstract: The Southern Ocean plays an important role in the uptake of atmospheric CO2. In seasonally ice‐covered regions, estimates of air‐sea exchange remain uncertain in part because of a lack of observations outside the summer season.… read more here.

DOI: 10.1029/2020jg006227
Abstract: The ocean coastal-shelf-slope ecosystem west of the Antarctic Peninsula (WAP) is a biologically productive region that could potentially act as a large sink of atmospheric carbon dioxide. The durat... read more here.

DOI: 10.1098/rsta.2017.0171
Abstract: Palmer Deep (PD) is one of several regional hotspots of biological productivity along the inner shelf of the West Antarctic Peninsula. The proximity of hotspots to shelf-crossing deep troughs has led to the ‘canyon hypothesis’,… read more here.

DOI: 10.3389/fmars.2017.00356
Abstract: Recent genetic investigations have uncovered a high proportion of cryptic species within Antarctic polychaetes. It is likely that these evolved in isolation during periods of glaciation, and it is possible that cryptic populations would have… read more here.
