This application was developed by the SC Department of Natural Resources to visualize the seasonal occurrence and spatial distribution for marine species (acoustically-tagged by numerous research groups) when those animals occurred in coastal waters off of SC and GA. The acoustic receiver detection data presented in the viewer is aggregated by species and month, which was done to convey trends without disclosing details about individual transmitters which are the analytical property of the taggers.
Source data for all animations are the sum of species days of detection at a given receiver location for each species in each month; detection frequency data were standardized to this metric to avoid bias associated with highly resident individuals. Because species days could be attributed to multiple days of data for a few individuals or only one day of data for numerous individuals, we did not produce animations for species with less than 30 total ‘species days’ of source data. As such, animations cannot be viewed for all detected species in the study.
