King tide photo initiative

Jan 5, 2011

The Washington Department of Ecology is asking for your photos of high tides through the month of February. Extreme high tides, known as king tides, occur once or twice a year when the gravitational pull of the sun and moon reinforce each other. 

Ecology is interested in documenting these high tides, because they may give us an idea of what to expect from rising sea levels caused by climate change.

Ecology officials say the sea level could rise 13 inches by 2100 in the Puget Sound region, and 11 inches on the state's central and southern coasts.

You can find out when high tides occur in your area at NOAA's tide prediction website, and upload your photos to the Washington King Tide Initiative flickr page.
