Abstract:

Euphausia superba standard lengths (SL) were measured at grid stations on the annual LTER cruises along the western Antarctic Peninsula (WAP). Krill were collected with a 2x2 meter, 700um mesh net fitted with a flow meter and towed obliquely to 120m.

Description:

Zooplankton net tows were conducted at Palmer LTER grid stations. Tows were double oblique with a 2x2-m square mouth (700-um stretch mesh) Metro net to 120 m. Density (#/1000 m3), in 1 millimeter size bins, was determined for Euphausia superba. Data includes tow location, north/south region, offshore gradient, and volume of water filtered by the net. This data complements the zooplankton data sets knb-lter-pal.199 and knb-lter-pal.212.

Abstract:

The Palmer, Antarctica, Long-Term Ecological Research (LTER) project is a member site of the Long-Term Ecological Research program, a network of sites investigating diverse biomes. The Palmer LTER sire has been in operation since 1990. The 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, and how the marine ecosystem west of the Antarctica peninsula is responding to a climate that is changing as rapidly as any place on the Earth. 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. The importance of the attenuated microbial food web and the roles of whales as a major predatyor in the seasonal sea ice zone ecosystem are also key focuses of the PAL-LTER. PAL studies these ecosystems annually over a regional scale grid of oceanographic stations and seasonally at Palmer Station. Cutting edge technologies such as autonomous underwater (and possibly airborne) vehicles, seafloor moorings, and numerical modeling, coupled with annual oceanographic cruises, and weekly environmental sampling, enables the Palmer Antarctica LTER to expand and bridge the time and space scales needed to assess climatic impacts. Palmer Station is located on Anvers Island west of the Antarctic Peninsula. 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.
