World Navies Today Main Page:

This list includes all seagoing research ships owned/operated by the Environmental Protection Agency (EPA) and the US Geologic Survey (USGS).

Ships not yet commissioned, or in long-term overhaul/conversion, are listed in italics. All classifications are purely unofficial and are based on an attempt to use standard classifications throughout all navies; they may or may not correspond to "official" designations. Where two dates are given (i.e. 1965/82), the first is the date of initial completion, and the second is the date of acquisition, conversion, or transfer. Designations given in (parentheses) are assigned but not displayed on the ship's hull.

All ships on this list carry the "R/V" prefix with their names.
