Title:Terminus lines of the Marr Piedmont Glacier at Palmer Station, Antarctica, from 1963 to 2023.
Alternate Identifier:DOI PLACE HOLDER
Abstract:

The Marr Piedmont glacier behind Palmer Station, on Anvers Island, Antarctica, has been in retreat for several decades. Since 1963, the terminus of the glacier has been intermittently mapped, initially with arial imagery, and then with GPS surveys. Annual mappings have occurred from 2017 onwards. This dataset includes both point and line GeoPackage spatial vector files, each of which includes the mapped terminus lines from each available year as individual layers.

Methods and protocols used in the collection of this data package
Description:

The location of the glacier terminus was determined using multiple methods. Terminus lines prior to 1987 (n=4) were obtained from historical aerial imagery. After 1987 (n=20), data were collected sporadically, generally every one to five years until 2017 when data was collected annually. A continuous GPS base station named PALM was installed in 1997 by the U.S. Geological Survey (USGS). Glacier terminus lines between 1997 and 2006 were recorded with an Ashtech Z-12. The PALM station was upgraded to a continuous Global Navigation Satellite System (GNSS) base station (Trimble NetR8 base receiver) named PAL2 by the University NAVSTAR Consortium (UNAVCO) in 2006. Measurements from 2006 to 2023 were made by walking the glacial melt boundary using either a Post Processed Kinematic survey or a Real-Time Kinematic survey with a backpack mounted Trimble R7, Pacific Crest RFM96W radio, and TSC2. Most surveys were conducted during the peak of the austral summer between January and March when the terrain is generally snow free.

The measured data points are available (in projected coordinates) in the "point" GeoPackage file. Some of the lines in the "line" GeoPackage file have been lightly edited to remove extraneous points and to extrapolate the glacier's boundary to the coast for analysis.

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.
