Marine Heat Waves in the NorthEast Pacific
Channel: Ocean Networks Canada
Date: 2019-12-12

In 2014, upper ocean temperatures in the northeast Pacific exceeded climatological norms by more than four standard deviations. In a vast area of open ocean, the surface waters remained 2 to 3 degrees warmer than normal for nearly a year. Linked to and feeding back on atmospheric conditions, the warm anomaly was locally referred to as “the Blob.” Marine ecosystems suffered both immediate and long lasting impacts. What caused the associated largescale patterns? Have we seen them before, will we see them again? How are they linked to climate change? These are questions to be addressed during the presentation.

This presentation was given by Richard Dewey, ONC Associate Director of Science. This talk was part of #VirtualBlueCOP25, a 24-hour around-the-world series of webinars held in conjunction with the 25th Conference of Parties meeting in Madrid, Spain.
