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.\n\ncdm_data_type = Trajectory\nVARIABLES:\nstudy_name (Study)\ntime (seconds since 1970-01-01T00:00:00Z)\ndepth (m)\nlatitude (degrees_north)\nlongitude (degrees_east)\nevent\nstation\nbottle\neub_16s_gene_copies (L-1)\naob_165_gene_copies (L-1)\narchaea_16s_gene_copies (L-1)\ncren_16s_gene_copies (L-1)\n...

Data on the species encountered (including marine mammals), their abundance, distribution and behavior. Data collected aboard cruises off the coast of the Western Antarctic Penninsula, 1993, 1999 and 2001. The objectives of the LTER seabird component during the 92-93 season cruises were similar.  These objectives included 1) determining the pelagic abundance and distribution of Adelie Penguins, 2) examining how the physical and biological characteristics of the marine environment influence these parameters and, 3) using these data to identify foraging areas that may be important to Adelie populations being studied as part of land-based  work at Palmer Station.  Secondary objectives included documenting the abundance and distribution of other seabirds and marine mammals within the LTER study area.  The focus of the January cruise was the nearshore foraging habitat,which required sampling at smaller scales.  All seabird censuses were thus conducted within approximately 100 kms of Palmer Station while traversing a sampling grid with stations at 10km intervals.  The first two days (18-20 January) of this cruise were spent covering the selected grid as rapidly as possible resulting in 45 transects spaced at 45-60 minute intervals.  There were no stops at the 10km stations during this Fast Grid phase.  Upon completion of the Fast Grid, a force 12 gale suspended data collection for 24 hours.  From January 22-25 the grid direction was reversed and the grid repeated.  During this Slow Grid phase, 2-M net tows were done at 10km intervals and BOPS and 1-M and 2-M net tows every 20 km.  All seabird censusesduring the cruise were done using the procedures outlined in theprevious paragraph.\n\ncdm_data_type = Trajectory\nVARIABLES:\nevent\ncruise_id\nstudy_name (Study)\ndepth (m)\nlatitude (degrees_north)\nlongitude (degrees_east)\ntime (seconds since 1970-01-01T00:00:00Z)\nstation\ngrid_line (km)\ngrid_station (km)\nsea_state\nsalinity (Sea Water Practical Salinity, 1)\n...

Dissolved inorganic nutrients including 5 macro nutrients: silicate, phosphate, nitrate, nitrite, and ammonium from water column bottle samples collected during annual cruise along western Antarctic Peninsula, 1991 - 2019. The inorganic plant macronutrients dissolved phosphate, silicate, nitrate, nitrite and ammonium are the major sources of nutrition for phytoplankton growth in seawater (with sunlight and inorganic carbon). Macronutrient distributions reflect the large-scale circulation patterns in the oceans and are useful properties to delineate water masses. Dissolved inorganic nutrients samples are typically collected in every Conductivity, Temperature, Depth (CTD)/Rosette cast performed on the annual LTER cruises along the western Antarctic Peninsula. Water samples are analyzed for dissolved nutrients with recognized standard oceanographic protocols for nutrient autoanalyzers (continuous flow analyzers). In Antarctic waters, dissolved inorganic macronutrients are seldom depleted to limiting concentrations except during heavy prolonged phytoplankton blooms. This is due to the fact that phytoplankton growth is more often limited by light or iron, and to the short growing season. .The inorganic plant macronutrients dissolved phosphate, silicate, nitrate, nitrite and ammonium are the major sources of nutrition for phytoplankton growth in seawater (with sunlight and inorganic carbon).

We rely on signatures of naturally occurring carbon (13C/12C, δ13C) and nitrogen (15N/14N, δ15N) stable isotopes (SI) as integrated proxies of penguin trophic foraging and food-web structure. Each season, study nests, where pairs of adults were present, were individually marked and chosen before the onset of egg-laying, and consistently monitored. When study nests were found at the one-egg stage, both adults were captured to obtain blood samples used for molecular sexing and stable isotope analyses, and measurements of structural size and body mass. At the time of capture, each adult penguin was quickly blood sampled (~1 ml) from the brachial vein. After handling, individuals at study nests were further monitored to ensure the pair reached clutch completion, i.e., two eggs. At approximate an average nest age of five and 15 days, offspring from study nests were captured and quickly blood sampled (<= ~500 µl for day five chicks, and <= ~1 ml for day 15 chicks) from the tarsus vein using a sterile needle and heparinized capillary tubes for day five chicks, and a sterile 3 ml syringe and heparinized infusion needle for day 15 chicks, again to obtain blood tissue for SI analyses. Study nests were monitored for chick survival to 25 days. At five weeks into chick-rearing, older crèched chicks of all three species were captured and quickly blood sampled from study rookeries near Anvers Island. Handling of crèched chicks occurred over a one or two day period, which varied seasonally and by species depending on nest initiation dates. Adélie penguin chicks at Avian Island were sampled on the same day Anvers Island Adélie penguin chicks were sampled. Adélie penguin chicks at Charcot Island, sampled during one season only on 25 January 2010, were handled three days after Anvers Island and Avian Island Adélie penguin chicks were sampled that year, i.e., 22 January 2010. Blood samples from crèched chicks (~1 ml) were taken from the brachial vein using a sterile 3 ml syringe and heparinized infusion needle following sampling procedures used for adult penguins to obtain blood tissue for SI analyses.

Cruise PD94-01 not included in time series for lack of samples Particulate organic carbon and nitrogen measurements from water column sample bottles, collected aboard Palmer LTER annual cruises off the Western Antarctic Peninsula, 1991 - 2018. Cruise PD94-01 not included in time series for lack of samples. All organisms are composed of organic matter. Organic matter is synthesized from dissolved inorganic carbon (dissolved CO2) and inorganic nutrients by phytoplankton photosynthesis, and consumed (oxidized) by respiration by heterotrophs (zooplankton and bacteria). The organic matter in seawater is a variable mixture of dissolved and particulate organic matter (DOM and Princeton Ocean Model (POM)). Typically DOM predominates over POM by an order of magnitude, but the relative amount of POM can be highly enhanced during large phytoplankton blooms. The principal elemental components of POM include organic carbon (POC), organic nitrogen (PN), there is no particulate inorganic N) and phosphorus (POP). These elements exist in a relatively stable, characteristic ratio of 106:6:1 (C:N:P) in seawater, known as the Redfield Ratio. Marine particulate matter is a complex mixture of live and dead plankton and detritus, and of carbohydrates, proteins, lipids and nucleic acids. POC and PN are enhanced in the euphoric zone, reflecting their origin by photosynthesis. The particulate pool is also a complex assemblage of particles of different sizes, shapes and densities. A simplified scheme divides the particles into large, rapidly sinking particles (10s - 100s of meters per day) and smaller, suspended particles. The transition between small particles and dissolved organic matter is typically specified by filtration through GF/F filters. POC and PN are analyzed for samples in the upper 100 meters on all regular grid samples.\n\ncdm_data_type = Trajectory\nVARIABLES:\nstudy_name (Study)\ntime (seconds since 1970-01-01T00:00:00Z)\nlatitude (degrees_north)\nlongitude (degrees_east)\ndepth (m)\ngrid_line\nstation (u2)\ncast_number\nbottle\n...
