Kernel Density Value Interpretation

[MariaManz]

Hello! I am working with shark tagging data, and I am running a kernel density analysis in ArcGIS Pro to determine areas of highest density. My output visually looks correct, however the value outputs are confusing to me. I understand they are the pixel density, but I am wondering how I can translate to the population density of sharks in that area so I can use the numbers as well as the image in my analysis. For example when I run my kernel density in RStudio my output shows that 75% of the population is within a certain area. Any clarification would be very much appreciated!

Hi Dan, 

Thank you again for your help I realized that one of my biggest issues was that I was using unprojected data, which is why I could not solve for a search radius. It is all fixed now and I was able to figure out my units! I ended up using a cell size of 18627. The advice to remove the pacific data as well as switch my method to geodesic helped so much! Thanks!!
