Operation IceBridge Flight Paths - Antarctica Fall 2010 Campaign

Operation IceBridge — a NASA airborne mission to observe changes in Earth's rapidly changing polar land ice and sea ice — is soon to embark on its fourth field season in October. The mission is now paralleled by a campaign to bring data to researchers as quickly as possible and to accelerate the analysis of those changes and how they may affect people and climate systems.

Data from campaigns flown prior to the inception of IceBridge will also be archived at NSIDC. These include data from the Airborne Topographic Mapper (ATM) instrument; mountain glacier data from the University of Alaska Fairbanks; and deep radar bedmap data from University of Kansas radar instruments. Combined with NSIDC's existing complete archive of data from the Geoscience Laser Altimeter System (GLAS) instrument aboard ICESat, researchers will be able to access a rich repository of complementary measurements.

IceBridge, a six-year NASA mission, is the largest airborne survey of Earth's polar ice ever flown. It will yield an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice. These flights will provide a yearly, multi-instrument look at the behavior of the rapidly changing features of the Greenland and Antarctic ice.

Data collected during IceBridge will help scientists bridge the gap in polar observations between NASA's ICESat — in orbit since 2003 — and ICESat-2, planned for late 2015. ICESat stopped collecting science data in 2009, making IceBridge critical for ensuring a continuous series of observations.

NASA DC-8 Flight Path
Terra and Aqua/MODIS/MODIS Mosaic of Antarctica (MOA) Image Map also referred to as: MOA
Mosaic - National Snow and Ice Data Center (NSIDC) and the University of New Hampshire
Staff from the National Snow and Ice Data Center (NSIDC) and the University of New Hampshire have assembled two digital image maps of surface morphology and optical snow grain size that cover the Antarctic continent and its surrounding islands. The MODIS Mosaic of Antarctica (MOA) image maps are derived from composites of 260 MODIS (Moderate-resolution Imaging Spectroradiometer) orbit swaths acquired between 20 November 2003 and 29 February 2004. The MOA provides a cloud-free view of the ice sheet, ice shelves, and land surfaces, and a quantitative measure of optical snow grain size for snow- or ice-covered areas. All land areas larger than a few hundred meters that are south of 60° S are included in the mosaic, as well as persistent fast ice regions and some grounded icebergs present near the coast in the 2003-2004 austral summer. The MOA surface morphology image map is derived from digitally processed MODIS Band 1 data. The optical snow grain size image is compiled using a normalized ratio of atmospherically corrected, calibrated band radiance data from Bands 1 and 2.
Landsat-7/ETM+/Landsat Image Mosaic of Antarctica also referred to as: LIMA
Mosaic - NASA/GSFC, British Antarctic Survey, USGS EROS Data Center
Mosaicing to avoid clouds produced a high quality, nearly cloud-free benchmark data set of Antarctica for the International Polar Year from images collected primarily during 1999-2003.
Note: While we identify the data sets used in these visualizations, we do not store any further details nor the data sets themselves on our site.
