Shackleton Ice Shelf News Today

Mass loss of the Antarctic Ice Sheet has been driven primarily by the thinning of the floating ice shelves that fringe the ice sheet1, reducing their buttressing potential and causing land ice to accelerate into the ocean2. Observations of ice-shelf thickness change by satellite altimetry stretch back only to 1992 (refs. 1,3–5) and previous information about thinning remains unquantified. However, extending the record of ice-shelf thickness change is possible by proxy, by me...

Abstract. Antarctic ice shelves provide buttressing support to the ice sheet, stabilising the flow of grounded ice and its contribution to global sea levels. Over the past 50 years, satellite observations have shown ice shelves collapse, thin, and retreat; however, there are few measurements of the Antarctic-wide change in ice shelf area. Here, we use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice...

Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade, whereas the steady-state approach would estimate substantial ice loss over the same period, demonstrating the importance of using time-variable calving flux observations to measure change.

The area and volume of surface meltwater lakes are highly variable year over year, finds a first-ever study looking at surface meltwater lakes near the East Antarctic Ice Sheet over seven years.

The Getz Ice Shelf in Antarctica. (Jeremy Harbeck/NASA via AP) (CN) — The worst-case scenario is always on the horizon. It holds our attention, but even the deer caught in the headlights has a chance to act. That’s why researchers at the University of Reading in the U.K. stress the risk of a catastrophic Antarctic ice shelf collapse and sea level rise due to climate change in a study published Thursday in the journal Geophysical Research Letters. The study evaluated the effects of global te...
