69.1 Methods
The plot showing the number of warm core ring formations and regime shift replicates figure 3 in Gangopadhyay et al. (2019). Detailed methods on the warm core ring time series and regime shift analysis are described in the manuscript.
69.1.1 Data sources
Gulf Stream charts from Jennifer Clark are the primary data source for the warm core ring analysis in Gangopadhyay et al. (2019). The Gulf Stream charts use infra-red (IR) imagery, satellite altimetry data, and surface in-situ temperature data in 3-day composite images are regularly produced by NOAA and/or the Johns Hopkins University Applied Physics Lab (fermi) group (see http://fermi.jhuapl.edu for more details).
69.1.2 Data extraction
The data from Gangopadhyay et al. (2019) were provided by Avijit Gangopandhyay, School for Marine Science and Technology, University of Massachusetts Dartmouth, MA.
69.1.3 Data analysis
A sequential regime shift detection algorithm was used to identify the regimes evident in the warm core ring formation time-series. See Gangopadhyay et al. (2019) for details.
69.1.4 Data processing
Warm core ring data were formatted for inclusion in the ecodata R package using this R code.
