Location of Palmer Station, AntarcticaCoordinates: -64.01000000043538, -64.7819999957808
Significance of Site
Air temperature data collected by the US Antarctic Program (USAP) document that the Antarctic Peninsula is among the fastest warming areas on Earth. Palmer station, one of three permanent USAP Antarctic facilities serves as a focal point for the monitoring and study of a variety of marine and terrestrial Antarctic processes.
Palmer Station is located on the Antarctic Peninsula.
Center Coordinate: Latitude 64° 46′ 27″ S, Longitude 64° 3′ 11″ W
Date of Time Series
June 21, 2004 - January 27, 2009.
The research site centers on a ~180,000 km2(~ 69,500 mi2) region surrounding Palmer Station. Elevations range from 10 m (32.8 ft) on land to 2,000 m (6,562 ft) below the sea surface. A 900 km (559 mi) long oceanic sampling grid stretches along shore roughly parallel to the Peninsula. Investigations at LTER Palmer site include:
- Physical forcing (solar, atmospheric, oceanic and sea ice) with emphasis on ecological consequences of annual and inter-annual variation
- Ecology and population biology of marine bacteria and archaeal, phytoplankton, zooplankton and seabirds
- Biogeochemical cycling of carbon and nitrogen
- Ecosystem responses to climate migration
- Physical/chemical/biological modeling linking ecosystem processes to environmental forcing
Lessons Learned from Analysis of Imagery Time Series
Here, land surface features, such as glaciers, are rapidly decreasing in area and thickness. This directly impacts both the terrestrial and marine ecosystems.
Importance of Time Series
In 1990, the National Science Foundation designated the Palmer Long Term Ecological Research (LTER) site as a Southern Hemisphere polar biome LTER site. Research focuses on the Antarctic coastal and open ocean marine ecosystem, terrestrial sea-bird nesting sites and regional oceanography along the Western Antarctic Peninsula. A primary research objective is to understand this marine ecosystem’s natural variability in order to discover and define long- and short-period natural cycles as well as the changes brought about by human activities. The time series documents changes in the LTER’s glaciers and adjacent landcover. Providing this high resolution time series to the international science community emphasizes the importance of sustaining ecological research and encourages collaboration at institutions all over the world.
