(2024) "Shallow Ice Radar (SIR) Dataset from Ross Ice Shelf, Antarctica (ROSETTA-Ice)" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/None. Abstract This Shallow Ice Radar (SIR) dataset is from the Frequency Modulated Continuous Wave (LFMCW) radar system on board the IcePod while deployed with the ROSETTA-Ice project during the austral summers of November 2015 - December 2017. SIR data was collected along the ROSETTA-Ice Survey Grid where possible. More detailed information is included in the ReadMe. This data was processed at Lamont-Doherty Earth Observatory using MATLAB scripts developed in-house by Tejendra Dhakal and Nicholas Frearson, using CReSIS 2013/14 MCoRDS scripts as a foundation. All levels of processed data are Matfiles as a result. Included in this dataset are the following: * SIR level1a Matfiles separated by ROSETTA-Ice Survey Grid Line Number; * SIR long-line images at 300dpi (PNGs) for easy data viewing, rendered in MATLAB from level1 data; * SIR internal reflector digitization picks (CSV), rendered manually using MATLAB picking scripts; * SIR digitization frame images (picked and un-picked) as JPGs output from picking process Creator(s): Cordero, Isabel; Frearson, Nicholas; Dhakal, Tejendra; Bertinato, Christopher; Chu, Winnie; Keeshin, Skye; Wearing, Martin; Spergel, Julian; Packard, Sarah; Dong, LingLing; Das, Indrani; Bell, Robin Date Created: 2024-05-22 Repository: USAP-DC (current) License: Creative Commons Attribution Only v4.0 Generic [CC BY 4.0] Spatial Extent(s) West: 161, East: -150, South: -86, North: -77 Temporal Extent(s) Start: 2015-11-09 - End: 2017-12-19 Award(s) NSF 0958658 NSF 1443534 NSF 1444690 Version: 1 Related Project(s) Development of an Ice Imaging System for Monitoring Changing Ice Sheets Mounted on the NYANG LC-130 Collaborative Research: Uncovering the Ross Ocean and Ice Shelf Environment and Tectonic setting Through Aerogeophysical Surveys and Modeling (ROSETTA-ICE) References Tinto, K.J., Padman, L., Siddoway, C.S. et al.
