We investigate ice shelf rift propagation using a … combination of GPS and seismic measurements near the … tip of an active rift in the Amery Ice Shelf. These … measurements reveal that propagation occurs in episodic … bursts…
Simulated sea ice thickness in the ORCA2-LIM coupled sea ice–ocean model is … compared with thicknesses from the Antarctic Sea Ice Processes and Climate (ASPeCt) database. We find a qualitative agreement of the large-scale patterns of ice thickness … distribution.
Creative remediation schemes have been implemented with success at petroleum-contaminated sites … in Alaska and Canada during the past decade. Contaminated media have been landfarmed, amended with fertilizers, augmented with microbial products, and manipulated with engineered systems.
Unmodelled sub-daily periodic signals can propagate … into time series of daily geodetic coordinates and tropospheric … estimates at various different frequencies. Geophysical … interpretations of geodetic products, particularly at seasonal … timescales…
This paper is an extension of the paper by King et al. (2000), where two techniques were described to … process GPS data collected on a floating Antarctic ice shelf. King et al. (2000)…
Although guidelines exist for approaches to Weddell seals (Leptonychotes weddellii) in … Antarctica, there has been no scientific assessment of the effectiveness of these guidelines in … minimising disturbance to the seals.
Micro-organisms are an important part of the Antarctic ecosystem contributing to the biogeochemical cycling of nutrients.
