Earth Watch Report - Mass Animal Death – Seas / Oceans
|Biological Hazard||USA||MultiStates, [ashore along 250 miles of coast from northern California to southern Oregon]|
|Scientists are trying to determine what caused millions of shrimp-like critters known as krill to die and wash ashore along 250 miles of coast from northern California to southern Oregon last month. Scientists say the strandings were reported from Newport, Ore. to McKinleyville in northern Humboldt County in mid-June, making it the geographically largest krill die-off on record. The Santa Rosa Press Democrat reports one theory is that a shift in the wind caught the animals near the ocean surface and caused them to be swept ashore. Officials say an examination of 10 krill found all were female and most carried sperm packets, suggesting they may have perished just after mating. Scientists have noted an abundance of krill that have drawn a concentration of whales and salmon this year.|

(CBS Seattle) - A new report from the Press Democrat says scientists are still puzzled as to how millions of krill died and washed ashore along 250 miles of coast from Northern California to southern Oregon last month.
The investigation so far has scientists thinking a shift in the wind may have caught the animals near the ocean surface, possibly in a mating swarm, and caused them to be swept ashore.
According to the Press Democrat, data from offshore ocean buoys showed that the wind rapidly shifted from the northwest to the southwest
