Actively evolving subglacial conduits and eskers initiate ice shelf channels at an Antarctic grounding line

The formation mechanisms of ice-shelf channels remain poorly understood. Here, using ice-penetrating radar data, the authors propose that ice-shelf channel morphology in the Roi Baudouin Ice Shelf, East Antarctica, is seeded by esker ridges, indenting the ice from below.

Glacial terminations as southern warmings without northern control

The timing and mechanisms of the transition from a glacial to an interglacial state are controversial. An analysis of Antarctic ice-core records indicates that glacial terminations may begin as millennial-scale warmings in the southern hemisphere that, unlike previous events, are not reversed by abrupt warming in the northern hemisphere.

Constraints on soluble aerosol iron flux to the Southern Ocean at the Last Glacial Maximum

Elevated deposition of bioavailable atmospheric iron may have enhanced carbon storage in the glacial Southern Ocean. Conwayet al. apply a novel rapid-filtration technique to iron trapped in Antarctic ice cores and show that glacial soluble iron deposition was an order of magnitude greater than the modern.

MBTPS2 mutations cause defective regulated intramembrane proteolysis in X-linked osteogenesis imperfecta

Osteogenesis imperfecta (OI) is genetically linked to autosomal dominant or autosomal recessive mutations. Here, Marini et al. describe two families with X-chromosome-linked OI with mutations in MBTPS2 that alter regulated intramembrane proteolysis and subsequent defects in collagen crosslinking and osteoblast function.

Southern Ocean sea-ice extent, productivity and iron flux over the past eight glacial cycles

Data from the Southern Ocean sea-ice extent, the biological productivity of the ocean, and atmospheric iron flux over the past eight glacial cycles indicate that during glacial terminations, changes in Patagonia apparently preceded Antarctic sea-ice reduction — showing that multiple mechanisms may be responsible for different phases of CO₂ increase during glacial terminations.
