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: A 1.4 m2 frame, 500-μm mesh Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) was used to collect meso- and macrozooplankton in discrete depth intervals during 2009-2017. Paired day and night MOCNESS tows were conducted at each PAL LTER process study station on annual research cruises. Eight discrete depth intervals were typically sampled during the upcast as follows: 500-400, 400-300, 300-250, 250-200, 200-150, 150-100, 100-50, and 50-0 m. Occasionally, the deeper intervals were not sampled when towing in waters shallower than the deep target depths or depth intervals were combined due to net sampling errors. A pair of day and night tows reaching a maximum depth of 1000 m was also carried out over the continental slope in 2017. Tow-yo casts were conducted at one station in 2009, such that intervals from 150-0 m were each sampled twice on a single MOCNESS cast. Volume filtered for each depth interval was estimated using a flow meter mounted on the MOCNESS. All euphausiids and salps collected in MOCNESS tows were identified and quantified at sea. Samples were then preserved in sodium borate-buffered 4% formaldehyde for later taxonomic analysis of non-euphausiid and salp taxa. Samples were size-fractionated using a 5-mm mesh, with all individuals in this larger size fraction identified and counted. At least 1/64 of the < 5-mm size-fraction was counted under a stereo dissecting microscope after dividing the sample with a Folsom plankton splitter. A minimum of 100 individuals of the most abundant taxon was enumerated in this smaller size fraction. Further description is available in the following paper: Conroy, J. A., D. K. Steinberg, P. S. Thibodeau, O. Schofield. Zooplankton diel vertical migration during Antarctic summer. Deep-Sea Research Part I. 2020. https://doi.org/10.1016/j.dsr.2020.103324 (external link). Abundance (individuals m-3) was determined for common taxa. Data includes tow location, time, depth, and volume of water filtered by the net. Taxa include: Lhelicina = Limacina helicina antarctica; Gymnosomata = gymnosome pteropods; Tomopteris = Tomopteris spp. polychaetes; Chaetognatha = Chaetognatha; Mgerlachei = Metridia gerlachei; Cacutus = Calanoides acutus; Cpropinquus = Calanus propinquus; Rgigas = Rhincalanus gigas; Pantarctica = Paraeuchaeta antarctica; Ostracoda = Ostracoda; Amphipoda = Amphipoda; Ecrystal = Euphausia crystallorophias; Tmacrura = Thysanoessa macrura; Sthompsoni = Salpa thompsoni. NA abundance values indicate the sample was not quantitatively analyzed for that taxonomic group.

attribute NC_GLOBAL summary String Zooplankton are a morphologically and taxonomically diverse group of animals. Many zooplankton feed on phytoplankton in surface waters and thus provide a link between primary producers and higher trophic levels. Other zooplankton reside in the mesopelagic zone and feed on detritus or on other animals. Depth-discrete density of zooplankton taxa was determined at process study stations on the annual Palmer LTER cruises along the western Antarctic Peninsula. Samples were collected with a 1.4-m2 frame, 500-μm mesh Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) towed obliquely to the surface from a depth of typically 500 m. MOCNESS tows were conducted in consecutive day-night pairs at each process study station. Zooplankton depth distributions vary between day and night as these animals conduct diel vertical migrations. Depth distributions also vary among zooplankton taxa based on species feeding ecology and life history traits. Zooplankton diel vertical migration contributes to the export of carbon and nutrients from the surface ocean to the mesopelagic zone.
