DOWNLOADING DATA VIA FTP

Data can be downloaded through a Web browser or command line via FTP. When using a Web browser, the FTP link first directs you to an Optional Registration Form that if filled out, will allow you to receive notifications about updates or processing changes related to that specific data set. After completing the Optional Registration Form, the FTP directory becomes available. For additional help downloading data through an FTP client, go to the How to access data using an FTP client support page.

NSIDC-0326

Ablation Rates of Taylor Glacier, Antarctica, Version 1

This data set provides glacier surface ablation rates for a network of approximately 250 sites on Taylor Glacier, spanning a period from 2003 to 2011. Here sublimation is the dominant ablation mechanism, though a few sites have accumulation. Ablation data are provided in meters water equivalent per year.

Data are available via FTP in space-delimited ASCII format.

Year Description
2003 Ablation poles were installed and measured for the first time during the 2002-03 season.
2004 All ablation poles were remeasured during the 2003-04 season.
L4 73 poles along the center line of the glacier were remeasured at the end of the 2003/04 season, for a summer ablation rate. (File is named *04_L4.txt)
2006 4 poles were measured by Hassan Basagic during the 2005/06 season.
2007 A selection of 163 poles were measured by Hassan Basagic during the 2006/07 season.
2010 10 poles were measured by Daniel Baggenstos during the 2009/10 season.
2011 17 poles were measured by Vasilii Petrenko during the 2010/11 season.

Data Acquisition Methods

Data were acquired using the traditional pole-height measurement technique. Aluminum conduit poles were initially emplaced 2 meters into the ice. Ablation rate is the difference between initial exposure and exposure approximately one year later, divided by the time interval between measurements. Initial measurements were in December 2002 and January 2003, and then again periodically between 2003 and 2011.
