NEWPORT – Oregon’s coastal residents will experience some of the year’s highest tides from Nov. 13-15.
Several groups in Oregon, including the CoastWatch program of the Oregon Shores Conservation Coalition and Surfrider, are participating in a project to document areas affected by such high tides.
The King Tide Photo Initiative is an international project designed to involve volunteers in documenting areas inundated by the highest tides that occur each year. These highest high tides are often called “king tides.” Volunteers are being asked to help build a visual record by taking photos of areas inundated by these high water events, and then adding the photo to a king tide photo website. Everyone is welcome to participate, they just need to pick a place, click a photo and share it on the Flickr web site.
More information about the project can be found on the Oregon King Tide website: www.flickr.com/groups/oregonkingtides/
King tides are normally occurring events caused by predictable astronomical factors that result in tides that are higher than most high tides. Areas affected by these king tides are susceptible to higher water levels from increased wave heights, winter storms and changes in sea levels.
Good king tide photos will show water levels adjacent to a fixed feature like a piling, seawall or bridge abutment. Including fixed features will allow actual water levels to be documented and tracked over time. Good photos also must include the location, the date and time the photo was taken, and the viewer’s direction for each picture. Two photos taken from the same spot, one during the king tide and the other at a typical high tide, are also very effective in highlighting these high water events.
King tides will also occur Dec. 12 through the 14 and Jan. 10 through 12, 2013.
