The rate and extent of global biodiversity change is surpassing our ability to measure, monitor and forecast trends. We propose an interconnected worldwide system of observation networks — a global biodiversity observing system (GBiOS)…
In late winter-early spring 2012, the second Sea Ice Physics and Ecosystems Experiment (SIPEX II) was conducted off Wilkes Land, East Antarctica, onboard R/V Aurora Australis. The sea-ice conditions were characterized by significantly thick first-year ice and snow…
Between March 15-19, 2022, East Antarctica experienced an exceptional heatwave with widespread 30-40° C temperature anomalies across the ice sheet. This record-shattering event saw numerous monthly temperature records being broken including a new all-time temperature record of -9.
Between March 15-19, 2022, East Antarctica experienced an exceptional heatwave with widespread 30-40° C temperature anomalies across the ice sheet. In Part I, we assessed the meteorological drivers that generated an intense atmospheric river (AR)…
An extraordinary sea ice tongue developed near 85E over a period of 30 days in … April–May 2002. The ice tongue extended to the north more than 800 km from the … surrounding ice edge and covered an area greater than 200,000 km2.
Previous studies of Antarctic mosses … employing RAPDs have reported extraordinarily … high levels of genetic variation, even within a single … clump of moss. This is unexpected given their … extreme isolation in Antarctica and lack of sexual … reproduction. We offer an alternative explanation:
The capacity of the polar flora to adapt is of increasing concern given current and predicted … environmental change in these regions. Previous genetic studies of Antarctic mosses have been of limited … value due to a lack of variation in the markers or non-specificity of the methods used.
Summary … 1. Previous studies of Antarctic clonal moss populations using RAPD markers have reported … extraordinarily high levels of genetic variation. This has been claimed to reflect somatic mutation, possibly resulting from elevated UV-B radiation. 2.
Airgun ‘shots’ from seismic surveys are powerful enough to be heard across ocean basins. At … close range, though, there is extraordinarily little understanding of the potential for these intense … sounds to cause temporary or permanent hearing threshold shifts (TTS/PTS) in marine … mammals.
