Trichocera maculipennis (Diptera)—an invasive species in Maritime Antarctica [PDF]

open access: yesPeerJ, 2018
Antarctica, with its severe conditions, is poor in terrestrial fauna species. However, an increase in human presence together with climate change may cause an influx of non-native species. Here we report a significant increase in colonized area of one of

King George Island spatial data model [PDF]

open access: yesGeo-spatial Information Science, 2001
Distribution, interoperability, interactivity, component are four main features of distributed GIS. Based on the principle of hypermap, hypermedia and distributed database, the paper comes up with a kind of distributed spatial data model which is in accordance with those features of distributed GIS.

Surface velocity and ice discharge of the ice cap on King George Island, Antarctica [PDF]

open access: yes, 2013
Glaciers on King George Island, Antarctica, have shown retreat and surface lowering in recent decades, concurrent with increasing air temperatures. A large portion of the glacier perimeter is ocean-terminating, suggesting possible large mass losses due ...
