Cetacean Monitoring in MITT, 2018

About

The Pacific Islands Fisheries Science Center’s (PIFSC) Cetacean Research Program (CRP) has conducted visual surveys for cetaceans in the waters surrounding Guam and the Commonwealth of the Northern Mariana Islands (CNMI) since 2010 as part of an ongoing effort to develop a record of cetacean occurrence in the region. During 24 August–9 September 2018, non-systematic visual surveys were conducted from small vessels off Saipan, Tinian, Aguijan, and Guam. A total of 1,168 km of trackline was surveyed and most was in Beaufort sea states of 2–4 (73%) and swell heights of 0–4 ft (71%). Twenty cetacean groups were encountered, resulting in the collection of 6,437 photos, 33 biopsy samples, and the deployment of 5 satellite tags.
