Vertical ocean heat transport near Antarctic ice shelves: data and processing code

Antarctic ice shelves, or the floating extension of terrestrial glaciers, help limit Antarctica’s contribution to global sea level rise by slowing the export of grounded ice into the Southern Ocean. Identifying the distribution of meltwater from the ocean-driven melt of these ice shelves helps determine where and at what rate they are thinning, providing insight into how quickly their buttressing effect is diminishing. In regions with rapid ice shelf melt, the resulting freshwater flux into the coastal ocean contains enough buoyancy forcing to reshape coastal currents and alter ocean stratification up to thousands of kilometers from the meltwater’s source. Global circulation models are employed to help understand how ice shelf meltwater modifies the Southern Ocean and are extended forward in time to attempt to predict the consequences of a future with increased ice melt. However, because they are unable to efficiently resolve small scale turbulent mixing, these models make assumptions r..., In Chapter 2, ship-based conductivity-temperature-depth (CTD) and lowered acoustic Doppler current profiler (LADCP) data was collected via in situ profiling aboard the Research Vessel Ice Breaker (RVIB) Araon. Seafloor bathymetry data was as produced by multi-beam sonar aboard the research cruise. Glider CTD and MicroRider (MR) data was collected in situ across two missions. Ice shelf bathymetry data is from Dow et al. (2018). Sea ice data was derived from Moderate Resolution Imaging Spectroradiometer (MODIS) imagery via the National Aeronautics and Space Administration (NASA) Worldview platform. Wind data were recorded by Automatic Weather Station (AWS) Manuela, part of the University of Wisconsin-Madison AWS Program.
In Chapter 3 and Chapter 4, ship-based vertical microstructure profiler data (VMP), again along with CTD and LADCP data, were collected via in situ profiling aboard the RVIB Araon. Glider-based CTD data were collected in situ across a single mission. Historical CTD and LA..., , # **Vertical Ocean Heat Transport near Antarctic Ice Shelves: Data and Processing Code**

## **Overview**

The goal of this collection of files is to allow for the replication of the MATLAB data processing and figure creation found in Vertical Ocean Heat Transport near Antarctic Ice Shelves. The entirety of these files and codes are designed to be run in MATLB version 2024b. Seven folders are provided across this data repository:

* *data*: all of the raw and processed data
* *ch1*: MATLAB scripts for recreating the figures in Chapter 1
* *ch2*: MATLAB scripts for processing Chapter 2 data and recreating the Chapter 2 figures
* *ch3*: MATLAB scripts for processing Chapter 3 data and recreating the Chapter 3 figures
* *ch4*: MATLAB scripts for processing Chapter 4 data and recreating the Chapter 4 figures
* *apxC*: MATLAB scripts for processing Appendix C data and recreating the Appendix C figures
