Dr Cait McCarry, from the University of Strathclyde, said, "We start with sea water. Then we add a krill and take a measurement (测量) of how much light the water takes in. 44. "
By comparing pictures taken by satellites, scientists will be able to guess how many krill live in different ocean areas. 45. This will also show how they're spread across different areas and how climate change and fishing affect them.
