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 taken from Go-Flo bottles and analyzed with HPLC for photosynthetic pigments. Samples were filtered onto GF/F filters and frozen at -60 degrees Celsius for a minimum of 24 hours. Pigments were then extracted in 90% acetone for 24 hours at -60 degrees Celsius. Samples were then injected onto a Waters C18 300mm column and separated by HPLC using a method adapted from Wright and Jeffrey, 1991. Peaks were identified by diode array spectrum analysis and integrated using Hitachi's D-6500 system; concentrations were calculated based on external standard curves in Microsoft Excel.\n\n0607 Season: Samples were filtered onto GF/F filters and frozen in liquid nitrogen for a minimum of 24 hours. Filters were extracted in 90% acetone for 24 hours at -60 degrees Celsius. Samples were then injected onto a C8 150mm column and separated by HPLC using a method adapted from Zapata et al, 2000. Peaks were identified by diode array spectrum analysis and by retention times of standards obtained from DHI Water & Environment and integrated using Hewlett Packard's 1100 Series system; concentrations were calculated based on external standard curves in Microsoft Excel.\n\n0708 Season: No season sampling conducted\n\n0809 Season: Samples were collected at various depths using GoFlow bottles. Filtration was done under low light using GFF filters. Filters were immediately stored in liquid nitrogen for no more than 3 months. Pigment extraction and HPLC methods employed followed Wright et al. 1991.

attribute	NC_GLOBAL	summary	String	Phytoplankton pigment sampling was led by Prezelin from the 1991-1992 season through the 1993-1994 season, and then by Vernet from the 1994-1995 season through the 2006-2007 season. Schofield is the third, and current lead, beginning in the 2008-2009 season. Methods have been kept consistent as much as possible over the full time series and different Principal Investigators. Phytoplankton have a suite of accessory pigments in addition to Chlorophyll a, including other Chlorophyll's (e.g. Chlorophyll b), Xanthophylls, and Carotenes. These accessory pigments can be used as chemotaxonomic markers to assess the composition and distribution of the phytoplankton community. For example, Fucoxanthin is a marker pigment of Diatoms, whereas Alloxanthin is a marker pigment of Cryptophytes. Accessory pigments also assist in photoacclimation and photoprotective processes. Water samples are collected throughout the water column at stations within the Palmer LTER region (primarily B and E, to 50m and 65m respectively). Water samples are filtered onto GF/F filters, and filters kept frozen at -80C until analysis. HPLC analysis is completed following Wright et al (1991). Following the guidelines set by NASA SeaHARRE, we use an internal standard and replicate injects on the HPLC to track recovery and replicability of the pigment extraction methods. Data is unavailable for the Palmer 2009-2010 season due to instrumentation problems and for the Palmer 2011-2012 season due to a freezer failure which resulted in the loss of samples. \n
