Description

Data source is ETOP05 &/or (the world data base) with a spatial resolution of roughly 5' (5 nautical miles) with depths given in feet. Largest grid section includes oceanic regions surrounding the LTER site including the eastern Bellingshausen Sea, Drake Passage and the Antarctic Peninsual (55S to 70S latitude, 55W to 80W longitude). The LTER Grid is an area west of the Antarctic Peninsula and covers an area of 900 km (roughly parallel to the peninsual) by 200 km (on to off-shore). Within this grid, cardinal lines spaced every 100 km along the peninsula and cardinal points spaced every 20 km on to off-shore comprise the basic LTER sampling stations.

Bottom Topography

Data source as above. The Palmer Grid is within the small box shown to the south east of Anvers Island. Fine-scale sampling positions near Palmer Station were selected to provide a set of fixed station locations within the Zodiac boating range of the station with some selected to be along the normal in/out access route of research vessels visiting the station (For more detail on the sampling grids, see Waters & Smith, 1991).
