Stranded! Could El Niño be Causing Higher Sea Lion Mortality?

California Sea Lions, like all marine mammals in U.S. territories, are carefully monitored by the National Marine Fisheries Service. In 2009, unusually high numbers of sea lions were stranding on California beaches - many malnourished or dead. This visualization examines the potential connection of these strandings to the co-occurring El Niño at that time.
