==Glaciology== Summer temperature and salinity measurements from 1994 to 2010 show the shelf is subject to more changeable oceanic forcing than other Antarctic shelves. Beneath cold surface waters, the [[thermocline]] was ~200 m shallower in 2007 than in 2000, indicative of shifting access of deep water to the continental shelf and ice shelf base. The calculated area-average basal melt rates was between 1.1 and 4.1 m of ice per year, making Getz the largest source of meltwater to the Southern Ocean.<ref>{{cite journal |title=Getz Ice Shelf melting response to changes in ocean forcing|doi=10.1002/jgrc.20298 |eissn=2169-9291 |year=2013 |volume=118 |issue = 9|journal=Journal of Geophysical Research: Oceans |pages=4152β4168 | last1 = Jacobs | first1 = S.|url=https://escholarship.org/content/qt5dh788mw/qt5dh788mw.pdf?t=nv19co |doi-access=free }}</ref> In February 2021, it was reported that the fourteen glaciers forming the shelf had all speeded up, and had lost 315 [[gigatonnes]] of ice since 1994. The cause of the speed up has been posited as "ocean forcing", a process where relatively warm deep ocean water melts the glaciers from below.<ref>{{cite web |url=https://www.bbc.co.uk/news/science-environment-56171302 |title=Climate change: West Antarctica's Getz glaciers flowing faster |last=Amos |first=Jonathan |date=23 February 2021 |work=BBC News |access-date=23 February 2021}}</ref> <gallery mode=packed heights=220> File:C74130s5 Ant.Map Grant Island.jpg|Shepard and Grant island File:C74126s1 Ant.Dean Island.jpg|Dean Island File:C74112s5 Ant.Map Martin Peninsula.jpg|Wright Island and Martin Peninsula in the east </gallery>
