2019/10/28
Scientists working on the ROSETTA-Ice project, a three-year, multi-institution survey of the Ross Ice Shelf in Antarctica, have assembled an unprecedented view of the seafloor beneath the ice sheet.In...
Scientists Report Large-Scale Surface Melting Event in Antarctica during 2015-16 El Nino
Scientists Large-Scale Surface Melting Event Antarctica 2015-16 El Nino
2017/7/21
The West Antarctic Ice Sheet, a landbound mass of ice larger than Mexico, experienced substantial surface melt through the austral summer of 2015-2016 during one of the largest El Niño events of ...
Melting Ice:What is Happening to Arctic Sea Ice,and What Does It Mean for Us?
Melting Ice Arctic Sea Ice What Does It Mean for Us
2015/7/16
Sea ice has emerged as the canary in the coal mine of climate change. Its summer extent in the Arctic has decreased by about 50% over the past decade, and the Arctic Ocean has undergone a regime shift...
Biological- and physical-induced oxygen dynamics in melting sea ice of the Fram Strait
Biological- and physical-induced oxygen dynamics melting sea ice Fram Strait
2014/7/10
We investigated the production, consumption, and exchange of O2 in melting sea ice to assess the biological- and physical-induced O2 turnover. The underside of the ice was covered with 5–20 cm3 large,...
Melting history of the Patagonian Ice Sheet during Termination I inferred from marine sediments
Patagonian Ice Sheet Termination I melting history Al2O3 flux marine sediments
2017/4/11
To investigate the melting history of the Patagonian Ice Sheet (PIS) during the last deglaciation, we reconstructed
Al2O3 flux in sediments from the Magellanes fjord (53°S) and southern Patagonia (55...
We consider the melting of ice in cold water vertically stratified with salt. The study extends previous investigations of ice melting in cold water at uniform salinity and in warm water with a salini...
Melting of Ice in Sea Water：A Primitive Model with Application to the Antarctic Ice Shelf and Icebergs
Sea Water Icebergs Antarctic Ice Shelf
2009/2/11
Steady-state conditions are assumed to exist everywhere in the case of melting of the underside of an infinite slab of ice floating in sea water. Basic transfer equations for heat and salt are establi...
Ice-Seawater Turbulent Boundary Layer Interaction with Melting or Freezing
Ice-Seawater Turbulent Boundary Layer
2009/1/13
A second-moment, turbulence closure model is applied to the problem of the dynamic and thermodynamic interaction of sea ice and the ocean surface mixed layer. In the case of ice moving over a warm, oc...
A Mathematical Model of the Ocean Boundary Layer under Drifting Melting ice
Mathematical Model Ocean Boundary Layer Drifting Melting ice
2008/12/27
A mathematical model of the ocean boundary layer under drifting melting ice is formulated, verified, and applied. The model is based on the conservation equations for heat, salt, and momentum and uses...
Ice melts when it is in contact with ocean waters that have temperatures above the in situ freezing point. The product is a mixture of meltwater and seawater having properties intermediate between tho...
Mantle Melting Beneath Mid-Ocean Ridges
Plate tectonics the earth's surface the magma oceanic crust
2015/7/22
The plate-tectonic revolution was initially "kinematic"—a description of plate motions across Earth's surface. Plate tectonics is now recognized as the surface manifestation of a greater process—circu...

The formation of basaltic crust at mid-ocean ridges and ocean islands provides a window into the compositional and thermal state
of the Earth’s upper mantle. But the interpretation of geochemical and...
