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: Discrete samples (300 ml) from Niskin bottle casts preserved with 200 ul saturated HgCl2 solution, sealed and returned to the lab for analyses. Sampling, storage and analytical protocols\nfollow the WOCE-JGOFS recommendations (Dickson and Goyet, 1994; Knap et al., 1994). The analyses are calibrated using standards provided by Andrew Dickson\n(http://andrew.ucsd.edu/co2qc/index.html).\n\nFrom 1993-2002, samples were analyzed at the University of Hawaii by David Karl and Chris Carillo (Carrillo et al., 2004). The 2003-2004 samples were collected by Hugh Ducklow and analyzed at Lamont-Doherty by Taro Takahashi and John Goddard. Samples after 2004 are analyzed in the Ducklow lab.\n\nThe average standard deviation for replicate samples (two separate samples drawn from the same Niskin bottle) was 0.15% for 2003-2007. The analytical error for replicate analyses of the same sample was 0.06%.\n\nCarrillo, C.J., Smith, R.C., Karl, D.M., 2004.

attribute	NC_GLOBAL	summary	String	Dissolved inorganic carbon and alkalinity of discrete water column samples, collected aboard Palmer LTER annual cruises of the Western Antarctic Peninsula, 1993 - 2018. There is a temporal uncoupling between Antarctic phytoplankton and bacterial processes. This affects the coastal ecosystem carbon cycle. Our sampling strategy and experiments are designed to evaluate the hypotheses that this uncoupling is caused by:1) dissolved organic carbon - bacterial interactions,2) temperature effects, and 3) direct competition and chemical antagonism.
