Abstract:

This dataset consists of delphinid echolocation clicks recorded at five sites in the Gulf of Mexico from May 2010 until March 2012. The sites are Desoto Canyon (DC), Dry Tortugas (DT), Green Canyon (GC), Main Pass (MP), and Mississippi Canyon (MC). Additional site information is contained in the deployment_info.csv file. Clicks were grouped into five-minute bins and clustered based on spectra. Clustered clicks are described herein as mean normalized spectra for each cluster formed, with the associated distribution of inter-click intervals (ICI) calculated from first time differences between clicks within each cluster.

Purpose:

This dataset was developed to assess the population of dolphins in the Gulf of Mexico at the time and following the Deepwater Horizon oil spill.

If a bin contained more than this number of clicks, a random subset of this size was selected. bin: Each set of parameters contained between bin tags (<bin> </bin>) is associated with a set of dolphin clicks within a five-minute window (bin) that has been clustered. One or more clusters are possible within each bin. bin_start_time: Start date and time of bin. Format is YYYY-MM-DDThh:mm:ss bin_end_time: End date and time of bin.

A single integer value. num_clicks_per_cluster: Number of clicks in each cluster.
