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	summary	String	The collection of biopsy samples from cetaceans within the near-shore waters of the Western Antarctic Peninsula (WAP) has been led by Dr. Ari Friedlaender starting in 2010. The Friedlaender group just recently joined the Palmer LTER in 2015, but prior collection of samples was leveraged from previous National Science Foundation (NSF) support and existing collaborations with Antarctic tour operations. Collection methods have been kept consistent, as the research group attempts to sample every whale encountered. Our current data set consists of three targeted species for collection, the humpback whale (Megaptera novaeangliae), Antarctic minke whale (Balaenoptera bonaerensis), and killer whales (Orcinus orca). Sample are kept frozen at -80°C until analysis following the completion of annual field work. Collection of these samples is still ongoing. The biopsy ID is the unique identifier for each collected sample and is used as the common field among the different analyses that are conducted on the sample to look at population and individual level demographic information. From these tissue samples, we can extract nuclear and mitochondrial DNA which provides us with information on the genetic sex, genotype (gene fingerprint), as well as haplotype of the individuals sampled. Additionally, from the blubber layer of the biopsy sample, our group can now successfully detect and quantify sex-steroid hormones, one of which is progesterone, that allows us to make inference on the pregnancy status of sampled individuals. Lastly, more recent work has begun to assess the microbial communities on the skin layer of the biopsy samples. Combined, these biological analyses provide an in depth understanding of the current population demographics and dynamics in these recovering marine species. \n
