attribute	NC_GLOBAL	comment	String	The Palmer, Antarctica, Long-Term Ecological Research project is a member site of the Long-Term Ecological Research program, a network of sites investigating diverse biomes. A team of researchers seeks to understand the structure and function of the Western Antarctic Peninsula's marine and terrestrial ecosystems in the context of seasonal-to-interannual atmospheric and sea ice dynamics, as well as long-term climate change. The PAL measurement system (or grid) is designed to study marine and terrestrial food webs consisting principally of diatom primary producers, the dominant herbivore Antarctic krill, and the apex predator Adelie penguin. An attenuated microbial food web is also a focus. PAL studies these ecosystems annually over a regional scale grid of oceanographic stations and seasonally at Palmer Station. \n\nPalmer Station is located on Anvers Island west of the Antarctic Peninula. The peninsula runs perpendicular to a strong climatic gradient between the cold, dry continental regime to the south, characteristic of the Antarctic interior, and the warm, moist, maritime regime to the north. North-south shifts in the gradient give rise to large environmental variability to climate change. Sea ice extent and variability affects ecosystem changes at all trophic levels. In addition to the long-term field and research activities, information management, graduate student training, education and outreach are an integral part of the program.

attribute	NC_GLOBAL	methods	String	General Methods: Samples (1.2-L) were collected from Niskin bottles on Palmer LTER cruises and immediately transferred to clear polycarbonate bottles. Samples were then spiked with 1.2 micromoles 15-NO3. Samples were incubated in an incubator maintained at seasurface temperature with flow-through seawater. Individual bottles were screened with a mesh screening to light levels of 100% surface irradiance, 33% irradiance, or 10% irradiance. After incubation, samples were filtered through a pre-combusted 25-mm GF/F filter and frozen at -80C. Filters were later thawed, acidified, and cut in half before being analyzed by mass spec at the UC Davis Analytical Facility. 15NO3 uptake was calculated from final PN del15N, [PN], and concentration ambient using the equations in Dugdale & Wilkerson (1986)\n
