Humans emitted millions of tons of the toxic element lead (Pb) into the atmosphere. The North Atlantic Ocean has been strongly affected by atmospheric Pb deposition, however the role of […]
During the late Paleozoic glacial ice extended from Antarctica across most of the Australian part of Gondwana. Maximum ice thickness over Antarctica was ∼5400–8000 m and over central Australia 2700–4000 […]
Methane seepage at the seafloor can form gas hydrate and sustain chemosynthetic communities of deep-sea animals. Most known hydrate seeps occur shallower than 2000 m on continental slopes, whereas hydrothermal […]
Peracarida is a large group containing twelve orders of brooding crustaceans, including the large orders Amphipoda, Isopoda, Tanaidacea and Cumacea, and a series of smaller orders, some restricted to isolated […]
The rapid expansion of glacial lakes in high-mountain regions, both in number and area, increases the risk of Glacial Lake Outburst Floods (GLOFs) to downstream communities. Optical remote sensing is […]
In this study, we report the response of migrating diurnal tides (DW1) in the mesosphere and lower thermosphere (MLT) region to the Madden‒Julian oscillation (MJO). The DW1 amplitudes are decomposed […]
Understanding how an ice sheet slips at its base is an important part of ice sheet models; this requires knowledge of the geological materials underlying the ice. Controlled-source seismic surveys […]
Emissions-driven (prognostic CO2) simulations are essential for representing two-way carbon-climate feedback in Earth System Models. We present an emissions-driven land–atmosphere coupled biogeochemistry (BGC) configuration (BGCLNDATM_progCO2) in version 2.1 of the […]
This project is intended to build time series of E. superba abundance and demography patterns related to hydrography and abundance and distribution patterns of E. superba predators, in the South […]
Sedimentary records can illuminate relationships between the climate, topography, and glaciation of West Antarctica by revealing its Cenozoic topographic and paleoenvironmental history. Eocene fluvial drainage patterns have previously been inferred […]
Antarctic Bottom Water (AABW) is derived from dense water that sinks from the Antarctic continental shelf to the deep ocean. The sinking of AABW is balanced by a return flow […]
Dotson Ice Shelf (DIS) is located in the Amundsen Sea sector of Antarctica, an area of rapid glacial mass loss due to ocean-driven basal melting. Here, warm Circumpolar Deep Water […]
