Ice shelves affect the stability of ice sheets by supporting the mass balance of ice upstream of the grounding line. Marine ice, formed from supercooled water freezing at the base of ice shelves, contributes to mass gain and affects ice dynamics.
Understanding basal processes across ice-sheet grounding lines is crucial in accurately modeling ice-sheet dynamics and estimating global sea-level rise. The grounding line, which demarcates the specific boundary between a grounded ice sheet and a floating ice shelf…
Ocean alkalinity enhancement is a potential strategy for gigatonne-scale atmospheric carbon dioxide removal. It uses alkaline substances to convert seawater carbon dioxide into (bi)carbonate, enabling uptake of additional carbon dioxide from the atmosphere.
Introduction: This document updates the research bibliography of SC/66b/SAN01 presented in 2016. The Southern Ocean Sanctuary (SOS) was established by the Commission in 1994. The area covered by the SOS in combination with the complementary Indian Ocean Sanctuary (IOS) is shown in Figure 1.
Carbon monoxide (CO) is a naturally occurring atmospheric trace gas, a regulated pollutant, and one of the main components determining the oxidative capacity of the atmosphere. Evaluating climate…
The diet of free-living pinnipeds is most frequently estimated through identification of otoliths, squid mouth-parts and exoskeletons … of prey in scats. This is because, although important prey types may not always be detected, sample collection is non-invasive and … analysis is easy.
This paper outlines work at La Trobe University on the development of a “fully digital” radar for space weather … investigations. The new radar will enhance the existing Tasman International Geospace Environment Radar … (TIGER) that probes beyond the horizon…
Fan-Beam and Pencil-Beam Radar Scaterrometers on many satellites in polar orbits, e.g. ERS-1/2, ADEOS-1/2 and QuikSCAT, have been designed primarily for estimation of vector winds over the … global oceans. However, these scatterometers…
A common technique for comparing the in situ microbial potential for mineralisation of petroleum hydrocarbons in different environments or under different remediation strategies, is by use of radiolabelled tracer studies.
Snow accumulation rates at the summit of Law Dome are examined on three different … timescales. For the full record covering the last ~ 90,000 years accumulation rate is … determined as an output of the model used for ice core dating.
Thorium-234 is increasingly used as a tracer of ocean particle flux, primarily as a means to estimate particulate organic carbon … export from the surface ocean. This requires determination of both the 234Th activity distribution (in order to calculate 234Th fluxes)…
