Imaging thermocline microstructure in 2D with swaths traced by wave-pumped χpods: dataset and code

Associated paper submitted to J. Geophys. Res. Oceans

Dataset summary

Location: 0°N, 140°W
Depth: 120 m
Period: 16-Sep-2014 to 19-Oct-2015

This data archive contains two types of data files:
data_yymmdd.mat
grid_yymmdd.mat
Each file contains 24 hours of data. There are 394 of each type.

Arrays in data_yymmdd.mat are single precision (except the 'time' array) to keep file sizes small.

Contents of the data files

Each Matlab file contains a single struct. These structs include readmes, which are reproduced in the full PDF readme (chipod_swaths_readme.pdf).

Files are grouped into months and zipped (yymm.zip) to ease downloading.

Reading the data file with Python

Example code to read the files into Python as dictionaries is given in the full PDF readme (chipod_swaths_readme.pdf).

Matlab code to produce the processed data

The code to read in raw chipod data and process them is primarily contained in the file 'swaths_paper_data_preparation.m'. This file calls three other files ('raw_load_chipod.m', 'deglitch.m', and 'bin.m'). All of these files are provided for completeness, but we are only archiving the processed outputs (not the raw voltage signals). Please email if more information is needed.

Matlab code for the convolutional neural network
