Under the Marine Mammal Protection Act, an unusual mortality event (UME) is defined as "a stranding that is unexpected; involves a significant die-off of any marine mammal population; and demands immediate response." Environmental modeling to predict where blue whales are in near-real time. When approached, the Blue Whale will swim away from the player, although it is slow and the player can easily catch up. The results of this research are used to inform management decisions and enhance recovery efforts for this endangered species.Â.

Determining the size of the blue whale population—and whether it is increasing or decreasing—helps resource managers assess the success of the conservation measures enacted. Additional threats include ocean noise, habitat degradation, pollution, vessel disturbance, and long-term changes in climate. Responding to dead, injured, or entangled blue whales.

They spend the summer in polar waters, feeding on shrimplike crustaceans called krill. If the player uses external devices or glitches to walk on water, they can encounter the whale and attempt to catch it to no avail. This consists of six objectives: NOAA Fisheries is working to minimize effects from human activities that are detrimental to the recovery of blue whale populations. This research involves increasing our understanding of the basic acoustic behavior of whales, dolphins, and fish; mapping the acoustic environment; assessing their seasonal distribution; and developing improved methods to locate cetaceans using autonomous gliders and passive acoustic arrays. NOAA Fisheries’ research cruises investigate blue whales’ habitat preferences and feeding ecology and conduct photographic and genetic identification.

NOAA Fisheries is investigating all aspects of acoustic communication and hearing in marine animals, as well as the effects of sound on whale behavior and hearing. Collisions with vessels are a major cause of injury and death for whales. The primary and preferred diet of blue whales is krilltiny shrimp-like animals. Once the most important of the commercially hunted baleen whales, the blue whale was greatly reduced in numbers during the first half of the 20th century. for assessing the effects of anthropogenic sound on marine mammals’ hearing.

We work with volunteer networks in all coastal states to respond to marine mammal strandings including large whales. Finally, this Plan provides a research strategy to obtain data necessary to determine blue whale taxonomy, population structure, distribution, and habitat, which can then inform estimation of population abundance and trends. Breaching is when the whale rises above the water's surface. Traditional whalers in the United States use hand-held harpoons to ensnare whales, and then kill them with high-powered rifles. The Blue whale also uses body language to communicate. There are five currently recognized subspecies of blue whales.
