Abstract
This Deep ICE (DICE) radar dataset is from the pulse-chirp depth sounding radar system on board the IcePod while deployed with the ROSETTA-Ice Project during the austral summers of November 2015 - December 2017. DICE data was collected along the ROSETTA-Ice Survey grid where possible. More detailed information is included in the ReadMe, including flight lines with data loss. DICE is a dual channel sensor with pulse-chirp rate of 1us and 3us, which means the data can be processed in four pulse/channel configurations: 1usCh1, 3usCh1, 1usCh2, and 3usCh2. The included dataset is 3usCh1 DICE, which is the preferred configuration. The preferred configuration is 3usCh1, which is included in this dataset. This data was processed at Lamont-Doherty Earth Observatory using MATLAB scripts developed in-house by Tejendra Dhakal and Nicholas Frearson, with CReSIS 2014 MCoRDS scripts as a foundation. As such, all processed levels of this data product are Matfiles. Included in this dataset are the following: * DICE level2a data Matfiles, separated by ROSETTA-Ice Survey Grid Line Number; * DICE long-line images at 300dpi (PNGs) for easy data viewing rendered in MATLAB from level2 data; * DICE Ice Base digitization picks, rendered manually using MATLAB picking script; * DICE digitization frame images (picked and un-picked) as JPGs output from picking process
