Miles off the Monterey Bay, in remote spots that researchers have neither the time nor resources to explore, hundreds of elephant seals, salmon sharks, albatross and sea lions are opening a new window for science.

Electronic tags attached to the marine animals send information via satellite to researchers worldwide about the temperature and salinity of seawater and how they change at different depths.

These factors, hard to assess by humans, help predict the earth’s climate and weather patterns, said Daniel Costa, a UC Santa Cruz professor of ecology and evolutionary biology and one of the researchers involved in the project.
