It is the ocean's which are the most accurate thermometer for measuring climate change, according to Dr. Josh Willis, who is an oceanographer with NASA's JPL.
Millions of shrimp-like critters called krill have died and washed ashore in northern California, US, last month. Though this krill loss is not expected to impact marine life local communities are asked to watch and report if they notice new stranding.
Scientists are still researching what exactly caused this massive die-off but it is known that it is geographically largest krill die-off on record.
