Abstract

Yearly census of Gulf Stream Warm Core Ring formation from 1980 to 2017. This continuous census file contains the formation and demise times and locations, and the area at formation for all 961 WCRs formed between 1980 and 2017 that lived for a week or more. Each row represents a unique Warm Core Ring and is identified by a unique alphanumeric code 'WEyyyymmddA', where 'WE' represents a Warm Eddy (as identified in the analysis charts); 'yyyymmdd' is the year, month and day of formation; and the ...

Thirty-eight years (1980-2017) of Gulf Stream Warm Core Ring census yielded a total of 961 WCRs and their their formation (birth), demise (last seen), area at formation and lifespan information were documented and are available here. Please note that this data set is the census data which is the result of analyzing a large number of Gulf Stream Analysis charts from NOAA and Jenifer Clark (see below). The basis for the charts were 6-12 hourly synoptic sea surface temperature data at 1.1 km from NOAA satellites with AVHRR and AVHRR2  instruments.This Census data was the result of analysis of more than 5000 such charts over the 38-year period (1980-2017). The charts were available 2-3 times a week for every week and are archived separately.

The process of creating the census and a brief description of the underlying charts are summarized here and also described by Gangopadhyay et al. (2019).
