Abstract: (no character limit, extra space will be provided as needed)
This metadata record documents the 95% kernel utilization distribution(KUD) for two species of parrotfish,
Chlorurus microrhinos and Chlorurus sordidus, during the 2013 summer at Palmyra atoll. The 95% utilization
kernel is a commonly used metric in animal home range studies and, in this study, was derived from 30min GPS
towed diver follows, with points recorded every 15 seconds. KUDs were computed for C. microrhinos at 3 backreef
sites and for C. sordidus at 4 backreef and 2 forereef sites.

Methods and Sampling:
Protocols and/or Procedures: (no character limit, extra space will be provided as needed)
KUDs were calculated from point data collected via 30 minute diver follows, with a GPS recording a location at
every 15 seconds. The GPS points were used to calculate Kernel Density Estimation (KDE) rasters using the KDE
tool within the Geospatial Modeling Environment platform. Parameters for the tool were as follows:
bandwith=“PLUGIN” and cellsize=1. The 95% isopleth for the KDE was then calculated with the isopleth tool
within the Geospatial Modeling Environment platform. The area of the resulting 95% isopleth was used for the 95%
KUD for the 30min follows of C. microrhinos and C. sordidus. The 95% KUDs are reported for each trial along
with the date, species, phase, size (TL), and forereef/backreef designation.
