<p>Understanding the subglacial bed topography of the Antarctic ice sheet is important for the boundary conditions of ice sheet modelling and the assessment of basal hydrological conditions. Moreover, inferring landscape evolution from the geomorphology can also provide insight into ice sheet inception and history. We utilise radio-echo sounding data from the BAS GRADES-IMAGE and TORUS radar surveys to geomorphologically interpret the bed topography in the Evans-Rutford Region of Antarctica, between the Ellsworth mountains and the southern Antarctic Peninsula. The GRADES-IMAGE survey is a legacy radar survey that has not yet been examined in detail in terms of subglacial bed topography and consists of 11,500 line kilometres of data along 22 lines. We have updated the subglacial bed picks to develop a new Digital Elevation Model of the region. Here we report preliminary results of the mapped subglacial landscape, with potential interpretations of the topographic patterns and landscape evolution. Geomorphological observations of the key features include identification of flat plateau surfaces at similar elevations, sitting between deep incised glacial troughs, some of which have potential tectonic controls.</p>
Patient stress is the biggest barrier between nurses and patients. It can make effective nursing techniques ineffective and slow the rate of recovery from illness and injury. Patient stress is a problem that can, however, be improved by any nursing team with the correct frame of mind and influence on the rest of the practice staff.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
