Description

The data are comprised of a spreadsheet with locations (latitude and longitude) of the centres of moss bed quadrats and labels for the quadrats. The quadrats are located at two sites: Antarctic Specially Protected Area 135 near Casey and on Robinson Ridge south of Casey.

The letter in the quadrat label indicates the vegetation community type: B for Bryophyte, T for Transitional and L for Lichen. The numeral indicates the transect number.

The latitudes and longitudes were obtained by Diana King, PhD candidate, School of Biological Sciences, University of Wollongong on 29 October 2014. See the Quality section of this record for the procedure used.
The locations are shown in maps 14450 and 14451 in the SCAR Map Catalogue (see Related URLs).
These locations supersede the quadrat locations which are a subset of the data described by the metadata record 'Moss beds at Casey: detailed map of experimental sites', Entry ID: ASAC_1313_Casey_Moss_Map_2003.

Quality

The starting point was point data with the locations of small metal tags glued to rocks near the quadrats. The tags act as markers for the quadrats. This point data was collected by Dr Arko Lucieer of the University of Tasmania in January 2010 using Leica 1200 dual frequency RTK GPS with a local base station. See the metadata record 'High resolution mapping of moss beds at ASPA 135, Robinson Ridge and near the Red Shed at Casey, January 2010' with Entry ID AAS_3130_moss_beds_2010.

The points were edited by Diana King on 29 October 2014 to move them to the centres of the quadrats using orthophotos of the two areas as a reference. The orthophotos were created from aerial photographs captured in February 2011 using a multi-rotor unmanned aircraft system (refer to the metadata record 'Unmanned Aircraft Systems (UAS) remote sensing datasets for ASPA135, Robinson Ridge, and Red Shed', Entry ID: AAS_4046_UAS).

Maps 14450 and 14451 in the SCAR Map Catalogue show the quadrat locations and the orthophotos (see Related URLs).
