TC - Change in Antarctic ice shelf area from 2009 to 2019

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 shelves in Antarctica from 2009 to 2019. Over the last decade, a reduction in the area on the Antarctic Peninsula (6693 km2) and West Antarctica (5563 km2) has been outweighed by area growth in East Antarctica (3532 km2) and the large Ross and Ronne–Filchner ice shelves (14 028 km2). The largest retreat was observed on the Larsen C Ice Shelf, where 5917 km2 of ice was lost during an individual calving event in 2017, and the largest area increase was observed on Ronne Ice Shelf in

Antarctic Ice Shelves Growing • Watts Up With That?

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.

Maori may have been first to explore Antarctica: study

Maori might have been the first to discover Antarctica, with connections to the icy continent and its surrounding oceans stretching back to the seventh century, researchers say. A new paper by University of Otago combines literature and oral histories, and concludes that Maori were likely the first people to explore Antarctica’s surrounding waters and possibly the continent in the distance. They write that Maori and Polynesian journeys to the deep south have been occurring for a long time, perhaps as far back as the 7th century, and are recorded in a variety of oral traditions. The oral histories of Maori groups Ngti Rrua
