Peatlands are important global carbon sinks but face increasing fire vulnerability under projected warmer and CO2-rich climate conditions. Past high-CO2 periods in Earth’s history serve as an important prospect to […]
Glaciers in Antarctica’s Amundsen Sea sector are retreating and thinning due to warm ocean inflow beneath ice shelves that buttress (restrain) glacier flow, but their future trajectory and implications for […]
Cetacean strandings provide early warning of emerging concerns regarding animal, ocean, and human health and allow insights into local cetacean population, density, distribution and mortality, and thus offer significant conservation […]
Provenance data from sediment delivered to the marine environment by icebergs can trace past ice sheet dynamics and help constrain the ice sheet models used in sea level projections. This […]
Sporadic mass strandings of the hydrozoan, Velella velella, along the US West Coast fascinate beachcombers and perplex oceanographers. Velella often arrive to the coast in the spring concurrent with a […]
Subglacial sedimentary basins in Antarctica are hypothesized to modulate ice flow and biogeochemical cycles via groundwater and geothermal feedbacks, yet their properties remain poorly constrained. Here, we present a joint […]
Emperor penguins are threatened by climate change and their population is predicted to decline rapidly this century due to changes in Antarctic sea ice. Remote sensing is a key tool […]
Multimodal satellite imagery provides complementary information for Earth Observation, but accurately combining heterogeneous sensors remains challenging in dynamic environments. Fast-changing regions, such as the Antarctic marginal ice zone, cannot fully […]
Extreme precipitation is a major contributor to the total precipitation over Antarctica and its variability. However, it remains poorly understood whether Antarctic extreme precipitation has undergone recent changes and, if […]
Over the last few decades, ice keels have intermittently bumped against the bedrock underneath Pine Island Ice Shelf. In general, it is thought that this process, termed regrounding, could enhance […]
Reconstructions of the opening of the Scotia Sea and the Drake Passage oceanic gateway have traditionally been based on considerations of ocean spreading and rifting between crustal blocks, and geological […]
Snow and rain are increasing in the Arctic. Climate model projections indicate a 50% increase in precipitation by the end of the century. This increase is driven by increased local […]
