Heinrich Stadial 1 (HS1; ~17.5-15 thousand years before present) was characterized by a weakening of the Atlantic Meridional Overturning Circulation (AMOC) that resulted in large hydroclimate changes across the global […]
A coupled modeling framework is often used to forecast the near-Earth solar wind conditions. This consists of a coronal model for close to the Sun and a heliospheric model for […]
The last deglaciation, ca. 17,000–11,000 years before present (yr BP), marks the most recent period of large-scale climate reorganization on Earth. However, the timing and spatial patterns of the initial […]
Central to improving our knowledge of ocean temperature change on Antarctica’s continental shelf is a better understanding of how ocean circulation drives the onshore flux of warm deep waters across […]
Sea ice in the Southern Ocean substantially modifies atmosphere–ice–ocean fluxes of energy, freshwater, carbon, nutrients, and other important properties. It redistributes these quantities in space and time, modifies water masses […]
At the Antarctic coast, ice shelves flow from the ice sheet and are vulnerable to future changes in sub-surface ocean temperatures at the southern margins. A better understanding of how […]
A unifying feature of the deciduous and evergreen shrubs contributing to the greening of the Arctic landmass—the process known as shrubification—is that their roots consistently form ectomycorrhizal or ericoid mycorrhizal […]
Plasmaspheric hiss is an incoherent, broadband, whistler-mode emission that is found primarily in the Earth’s dense plasmasphere and is believed to be largely responsible for the formation of the slot […]
During the last glacial period, the iconic Greenland ice-core records provide evidence of interstadial warmings with various durations ranging from a century to millennia. However, whether differences in interstadial duration […]
The phylum Echinodermata is a familiar constituent of almost every marine environment and a predominant portion of the fauna in some regions. As with most marine taxa, the clade is […]
Microplastic release in Antarctica is an issue of increasing concern, despite the limited human presence in the region. This study estimates the annual release of microplastics from the wastewaters of […]
In this study, we have investigated short-period ( 1 hr) atmospheric gravity waves (AGWs) in the Arctic mesosphere-lower thermosphere (MLT) region during January of 2014, 2015, and 2016. We used […]
