..."Bromirski, who got a Ph.D. in seismology in 1993, knew that those wave-to-wave interactions caused seismic signals that could be detected underwater and on land, "but nobody had tried to invert the seismic signals for wave height," he said.
Interpreting the seismic data was crucial to understanding how wave heights had changed over most of the last century, Bromirski said. Buoys that measure wave height along the West Coast had been collecting data only since 1980, after the rapid intensification of greenhouse gas emissions had already begun.
By using seismic data, Bromirski could look for patterns in a longer window of time. Two notable periods stood out. From 1939 to 1947 and 1957 to 1965 there were extended periods of "exceptionally low winter wave activity," Bromirski said. "There's been nothing like that since 1970.""
