GLACIER REGIONS

Index dataset: GTN-G Glacier Regions

Scientific data identifier for version 2017: 10.5904/gtng-glacreg-2017-07

Creator: Global Terrestrial Network for Glaciers (GTN-G)

Title: GTN-G Glacier Regions (GlacReg)

Publisher: Global Terrestrial Network for Glaciers (GTN-G)

Publication year: 2017

Release date: 2017-07-10

Citation: GTN-G (2017): GTN-G Glacier Regions. Global Terrestrial Network for Glaciers. DOI: 10.5904/gtng-glacreg-2017-07. Online access: https://dx.doi.org/10.5904/gtng-glacreg-2017-07.

Description: Glacier regions are useful for regional assessments of glacier change and other parameters (WGMS 1989, Dyurgerov 2002, Radić and Hock 2010, Pfeffer et al. 2014). This dataset defines 19 first-order glacier regions and more than 90 second-order regions encompassing all of earth’s glaciers and ice caps. It is an update of the RGI dataset 5.0 (Arendt et al., 2015) with some small modifications from the WGMS (2016) glacier regions. Both of these datasets derive ultimately from glacier regions defined by the GLIMS project around the year 2000 and from Radić and Hock (2010).

This GTN-G Glacier Regions dataset is a joint set of regions recommended by the Global Terrestrial Network for Glaciers (GTN-G) Advisory Board, the Global Land Ice Measurements from Space initiative (GLIMS), the Randolph Glacier Inventory (RGI) Working Group of the International Association of Cryospheric Sciences (IACS), and the World Glacier Monitoring Service (WGMS). These glacier regions are implemented in RGI 6.0 (RGI Consortium, 2017) and in the Global Glacier Change Bulletin (WGMS 2017).

Details of how the GTN-G glacier regions differs from RGI 5.0 (Arendt et al. 2015) are listed below:

  1. A) Order 1 regions:
    (1) Northern boundary of region 2 (Western Canada and USA) is moved south to exclude Melville Island glacier subregion 02-01 (shrinking the region);
    (2) Western boundary of region 3 (Arctic Canda North) is moved west to include Melville Island subregion (expanding the region);
    (3) Extra box tacked onto region 10 to include Japanese “glaciers” (expanding the region).
  2. B) Order 2 regions:
    (4) Subregion 02-01 Melville Island is moved to region 3 (Arctic Canada North)
    (5) New sub-region 10-07 for the expansion that covers Japan
    (6) Subregion 19-31 renamed (from Antarctic Ice Sheet) to “Antarctic Mainland” in order to cover glaciers such as on the Antarctic Peninsula or in the Dry Valleys.
