Numerous marine mammal populations worldwide are declining because of increased anthropogenic and natural threats, including infectious disease. Brucella ceti, morbillivirus, and herpesvirus have been detected from stranded cetaceans and been recognized as pathogens that may result in considerable cetacean morbidity and mortality. Beaked whale circovirus has been reported in multiple cetacean species in Hawaii, USA, and the western Pacific Ocean, but the pathologic relevance in these species remains uncertain. We screened for the presence of Brucella in 66 cetaceans of 17 species that stranded in Hawaii 2000-24 by targeting the insertion sequence 711 partial sequence using PCR.

Western gray whale detections in western Pacific
June 8, 2026
Gray whale vocalizations are well-known and have been detected on mobile U.S. Navy passive acoustic monitoring (PAM) systems for decades. Gray whales produce highly variable and complex signals. Given some historical and conservation interest in the overall distribution and migratory patterns and behaviors of gray whales in the north Pacific, the Navy has conducted systematic monitoring for the calls of gray whales in times and areas that would inform species distribution patterns.
