Example data files for shipgrav, from TN400 and SR2312

This repository contains an archive of data files used in example calculations for the Python package shipgrav. The shipgrav software is created and maintained by the Potential Field Pool Equipment facility (PFPE) and is designed for reading and processing marine gravimeter data from UNOLS vessels.

TN400 on R/V Thompson was a transit under Chief Scientist Robert Kamphaus (UW)SR2312 on R/V Ride was under Chief Scientist Rob Harris (OSU)More data from both of these cruises can be found at Rolling Deck to Repository (R2R, rvdata.org)

The data contained in this repository are:

TN400 DGS raw and laptop data

SR2312 DGS raw data

R/V Ride DGS meter and Hydrins metadata

satellite-derived FAA tracks for comparison to shipboard data

an example file for RMBA calculation

The satellite-derived FAA values come from the V32.1 Global Gravity grid developed at Scripps Institution of Oceanography-University of California San Diego. This grid contains data from SIO, NOAA, and NGA.
