Cetacean Data Availability

This page illustrates the availability of cetacean data by regions of the US Exclusive Economic Zone (EEZ) and by month. Data sets are classified by tiers that indicate their relative quality.

NOTE: Expert-based presence for each species was designated at the temporal resolution of an entire year, such that a species is considered “present” if it is known to occur in that region at any time during the year. This tier does not provide information on species presence during specific months.
