And windier seas have resulted in an increase in average wave height as well.

Extreme wave height has increased a little less than a foot, or 5 percent.

That, lack of visibility, wind speeds and wave height would make navigation of the channels under the bridge hazardous.

To get a handle on the oceans, researchers gathered 4 billion observations of wind speed and wave height collected between 1985 and 2018 by 31 satellites.

The spacecraft, costing a total of $157 million, will also be able to measure wave height to estimate wind speeds better.
