This report summarizes the surveys, data collection, and analyses conducted by PIFSC for cetaceans within the Mariana Archipelago to evaluate the current state of the data with respect to the overall goal of cetacean population assessment. Identification photos and encounter data from surveys conducted by other researchers were contributed by the U.S. Navy for incorporation into the PIFSC data sets for a variety of species and are therefore also represented in the summary reported here. The report is not intended to be an exhaustive review of all cetacean effort conducted in the archipelago, though all significant survey efforts, including those not conducted by PISFC are referenced and, on occasion, discussed in greater detail.
