This work was done in part at the Jet Propulsion Laboratory, California Institute of Technology under a contract from NASA. The Argo float data were collected and made freely available by the International Argo Program and the national programs that contribute to it (https://argo.ucsd.edu,https://www.ocean-ops.org). The Argo Program is part of the Global Ocean Observing System. ECCO is supported by NASA’s Physical Oceanography, Modeling Analysis and Prediction, and Cryosphere programs. We thank John Toole, Magdalena Andres, and the many other scientists and mariners who went to sea to collect the in situ observational data, particularly through the Line W program.

Coordinate Information

The following table shows information about the dataset coordinates in the standardised version, including coordinate name remapping from the original, if any:

Coordinate	Description	Units	Size	Min Value	Max Value	Missing %
depth → DEPTH	Depth: Depth below surface of the water	m	(560,)	0.00	5590.00	0.0%
pressure → PRESSURE	No description available	unknown	(560,)	0.00	4757.83	0.0%
date → TIME	Time: Time of each observation in datetime format	seconds since 1970-01-01T00:00:00Z	(120,)	2004-05-16	2014-04-17	0.0%
time → TIME_FRACTION	Time in year.fraction of year: Time of each observation which starts with the year and is followed by the fraction of the year that has passed at the time of the observation. For example, 2004.5 would correspond to June 30, 2004.	year.fractionofyear	(120,)	2004.38	2014.29	0.0%
