U.S. Virgin Islands Benthic Habitat Spatial Data
I am enamored of this dataset; it is essentially “marine ecological regions” for U.S. territorial holdings in the Carribean (Puerto Rico, U.S. Virgin Islands):
Along with simply satisfying curiosity, I think it might be useful for understanding the spatial distribution and preferred habitat of invasive lionfish in the Virgin Islands, in a broad sense.
Pairing occurrence records with habitat classifications may provide useful insights. There is a Java application called Weka that can reveal clustering in your data.
By pairing this data with the names of the delineated habitat, I believe the tabular data within the spatial dataset can reveal any natural clustering (Although the clustering may be biased towards popular dive / snorkeling sites).
Another interesting data point which clustering can reveal is the depth at which the animals are most often found. However, this again may simply be a reflection of the “preferred depth” of divers (e.g., not greater than 30 m).
