Current ice flow directions (black solid arrows) show flow has been diverted northward into Horseshoe Glacier (HSG).
All but one of the sites displays lineated bedforms aligned with the current ice flow, which are typical of features found on palaeo-ice-stream beds25,26,27,28,29,30(Fig. 2).
It also shows the location of blue-ice areas, drawn-out medial moraines between the MH and IH massifs, and current ice flow directions (black arrows).
Such conditions, depending on the time of year, include, but are not limited to: extreme cold, freezing spray, snow, extended periods of low light, strong winds, dense fog, sea ice, strong currents, and dangerous sea states.
These studies have focused on ice movements, currents, and the behavior of whales and other animals.
It's the hovercraft that makes the setup truly unique: Using SABVABAA, the researchers can travel up to 100 kilometers from their floating base, assessing ice properties, currents, and water temperatures.
It took a week to reach Elephant Island, the ice and currents inhibiting progress.
"From an Arctic perspective it's not only about an increase in temperature, it's a complete change in the ecosystem - salinity, ice melt, flow, currents - all of these together will have an impact".
According to ICE's current immigration enforcement policies, immigrants convicted of a felony are most at-risk for deportation.
