A new lungworm in muskoxen: an exploration in Arctic parasitology.
Ruminants are vital elements of the Holarctic ecosystem. Little is known, however, of the structure or biology of their parasite fauna, particularly in North America. Global warming, coupled with increasing human activity in the Arctic, requires enhanced international interdisciplinary efforts to better understand the many factors, including parasites, that influence the population health of ca...
متن کاملToward extraplanetary under-ice exploration: Robotic steps in the Arctic
This paper describes the design and use of two new autonomous underwater vehicles, Jaguar and Puma, which were deployed in the summer of 2007 at sites at 85◦N latitude in the ice-covered Arctic Ocean to search for hydrothermal vents. These robots are the first to be deployed and recovered through ice to the deep ocean (> 3500m) for scientific research. We examine the mechanical design, software...
متن کاملLong-term recovery patterns of arctic tundra after winter seismic exploration.
In response to the increasing global demand for energy, oil exploration and development are expanding into frontier areas of the Arctic, where slow-growing tundra vegetation and the underlying permafrost soils are very sensitive to disturbance. The creation of vehicle trails on the tundra from seismic exploration for oil has accelerated in the past decade, and the cumulative impact represents a...
متن کاملOffshore Exploration in the Arctic: Can Shell’s Oil-Spill Response Plans Keep Up?
Shell must cease drilling well before the water freezes over lest a late-season blowout cause oil to accumulate under the ice through the winter.
