Our sampling program addresses multiple spatial scales within one regional scale grid of ~50 regularly occupied oceanographic stations at which core measurements are conducted permitting repeated sampling on both seasonal and annual time scales, covering short and long-term ecological phenomena, and specific mechanistic studies. The sampling grid adds a unique strength to both the field and modeling programs by unifying measurements across all field components and facilitating data integration.
The Palmer LTER nominal sampling grid occupies a region ~200 km in cross-shelf width running ~1000 km along the western Antarctic Peninsula. The station locations in the sampling grid lie upon cross-shelf sample lines or grid lines spaced 100 km apart and grid stations on these lines spaced 20 km apart. Our focus is confined to the 200-600 lines, lines with the longest consistent sampling over the first 10 years of LTER data.
