Seismic blasting used in oil exploration can reach 250 decibels and be heard for miles. It can cause hearing loss, disorientation and disturb essential marine mammal behaviors such as feeding and breeding. Just over 300 Cook Inlet beluga whales are left after four more washed up dead in Cook Inlet in the past two weeks.

The current expanse of warm water stretches from Alaska to Southern California to Hawaii. It appears similar to conditions five years ago when the original “blob” was first taking shape, federal scientists said, although so far, the warmer-than-normal waters extend down only about 150 feet below the surface, rather than 600 feet five years ago.
Although Arctic-wide warming during the 20th century is well documented, little is known about the response of sea-ice to abrupt warming and it is unclear when the sea-ice decline started. Data coverage in this region is highly restricted, with observation-based satellite data only available since the 1970s, too short to accurately calibrate climate models.
“We were alarmed to find that diatoms were so negatively affected, with some species likely to have diminished silica production before the end of this century,” says Dr Petrou.
