Description: This file contains the Start and Stop latitudes and longitudes for all of the transects analyzed in this study. This was used to generate the map in the manuscript (Greer et al., 2022). Note that all longitudes in the Western hemisphere should be negative. This applies to all data except those collected in the Mediterranean Sea. Column names, descriptions, and units: Location = transect name. Start Lat = start latitude; units = degrees North. Start Lon = start longitude; units = degrees East. Stop Lat = stop latitude; units = degrees North. Stop Lon = stop longitude; units = degrees East.

Description: This folder contains the manually verified doliolid identifications in the Gulf of Mexico and Southern California. Southern California had individual “casts” analyzed, so the times for these chunks of data are also contained in this folder. In these files, each row is an individual animal, and the associated data are similar to full descriptions of the oceanographic data collected. File names and descriptions: 726dolenv3cats.csv = doliolids manually classified into 3 life stages from July 26, 2016. This is for the eastern corridor (ECORR) in the northern Gulf of Mexico. Each row is an individual. dateTime_ranges_transect_2_3.csv = contains the start and stop times for each profile in the San Diego dataset. This is required to accurately measure the volume sampled. Two transects were analyzed (transects 2 and 3). Each profile has a sequential cast number, with a start and stop time in hours:minutes:second and Julian time. doliolids_transects2_3_presence_only.csv = contains the counts of pelagic tunicates (i.e., doliolids) in the images, along with the corresponding oceanographic data.
