Long Duration Underwater Glider Dataset: Indian Ocean From Perth, Australia To Mirissa, Sri Lanka

This data was collected using an underwater research vehicle, Slocum glider. The glider is an autonomous robot that is able to measure several water properties from surface to 1000 m depth. The duration of missions for underwater gliders are on the order of 1 month to over a year. Detailed here is the live satellite telemetered dataset as transmitted during mission.Dataset includes positional data, vehicle engineering, attitude, temperature, salinity, and depth averaged currents. Raw data as well as some derived variables from the raw data are included in this dataset. This data is transmitted every couple hours and comprises of a subset of the data stored on the vehicle's internal memory.The data is returned in segmented files which comprises of an underwater segment bookended by GPS positions. Because most analysis require longer time series, effort has been taken to conglomerate the segment datasets into a single continuous dataset stitching together the segments. The platform chosen for this is currently MATLAB.This data can provide the community with an example dataset of underwater glider data pertinent to a long duration and low energy glider mission. It also includes ocean measurements of temperature, salinity, and ocean currents. Built into the dataset object are various functions designed to help the user navigate and display a glider's collected data.The effort is being made to serve future datasets, 2017 and onward, via ERDAPP at the following location: http://slocum-data.marine.rutgers.edu/erddap/index.htmlAnalyzed by the Applied Ocean Research article: Modeling for the Performance of Navigation, Control and Data Post-Processing of Underwater Gliders where it is used for flight efficiency analysis as well as ocean model comparisons.
