Influence of Sea-Ice Anomalies on Antarctic Precipitation Using Source Attribution in the Community Earth System Model [PDF]
We conduct sensitivity experiments using a general circulation model that has an explicit water source tagging capability forced by prescribed composites of pre-industrial sea-ice concentrations (SICs) and corresponding sea surface temperatures (SSTs) to

Abstract Fossil micrometeorites (MMs) recovered from lithified sedimentary rocks, particularly iron‐rich (I‐type) cosmic spherules (CSs) provide valuable insights into past dust‐forming events. Their abundances, when combined with estimates of local sedimentation rates can be used to reconstruct the flux of extraterrestrial dust.

Changes in Antarctic bottom water off the Wilkes Land coast in the Australian-Antarctic Basin
Long-term changes in Antarctic Bottom Water (AABW) off the Wilkes Land coast, East Antarctica, were investigated using historical hydrographic surveys and data from Deep Argo floats. Since the 1980s at the latest, AABW has contracted by approximately 11–14 m yr-1 and undergone isothermal freshening by approximately –0.6 × 10-3 yr-1. The contraction and

Expert opinions regarding the concept of blue carbon in seaweed systems
SUMMARY A collection of expert opinions critically evaluates the role of seaweed in blue carbon strategies for climate change mitigation. While the concept of fast‐growing seaweed to capture atmospheric carbon is appealing, the experts largely agree that its potential for direct, long‐term carbon sequestration is currently overstated and faces ...

Centric diatom communities found in the Antarctic sea ice
It has been generally accepted that the ice algal communities are dominated by pennate diatoms in the Arctic and Antarctic seas. However, two ice algal communities found near the Antarctic Continent were dominated by centric diatoms.

Rapid submarine ice melting in the grounding zones of ice shelves in West Antarctica. [PDF]
Enhanced submarine ice-shelf melting strongly controls ice loss in the Amundsen Sea embayment (ASE) of West Antarctica, but its magnitude is not well known in the critical grounding zones of the ASE's major glaciers.

Impact of Weddell Sea shelf progradation on Antarctic bottom water formation during the Miocene
The Weddell Sea is a main location of bottom water formation and, thus, an important component of global ocean circulation. In this study we examine the ocean and climatic responses to a shelf progradation induced by ice sheet advance and glacially ...

Recruitment, growth and mortality of an Antarctic hexactinellid sponge, Anoxycalyx joubini. [PDF]
Polar ecosystems are sensitive to climate forcing, and we often lack baselines to evaluate changes. Here we report a nearly 50-year study in which a sudden shift in the population dynamics of an ecologically important, structure-forming hexactinellid ...
