Snap the shore, see the future!

Jan 10-12, 2017

Do you like to take photos, spend time outside, and are concerned about coastal flooding in our communities?  Help document winter storms and extreme high tides through one or all of these local projects!

When are the King Tides in January 2017?

Urban Tides Initiative

USC Sea Grant

Urban Tides is a community based science effort launched in 2015 to document current tidal lines, beach erosion, and coastal flooding. The initiative has designated a series of beach and wetland locations where the public can take photographs of changing tides, flooding and erosion, then upload them into the Urban Tides database.

Storm Photo

Southern California Coastal Ocean Observing System (SCCOOS)

UCSD Scripps Institution of Oceanography

The goal of stormphoto is to get the help of citizen scientists to document flooding events from Imperial Beach in San Diego county to Point Conception.

California King Tides Initiative

The California King Tides Initiative is asking members of the public to photograph extreme high tides along our local coastline to highlight how coastal homes, infrastructure, and ecological habitats may be affected by future sea level rise.

Some of the most powerful images are taken in coastal areas that are subject to flooding and erosion, and of places where high water levels can be gauged against familiar landmarks (such as cliffs, rocks, roads, buildings, bridge supports, sea walls, staircases, dikes, and piers). Below are some local locations where you can capture the King Tides.

San Diego: San Diego Bay, Oceanside Beach, San Elijo Lagoon, Del Mar Dog Beach/San Dieguito Lagoon Entrance, Torrey Pines (where Penasquitos enters the ocean), La Jolla Shores, Mission Beach, Imperial Beach, and the Tijuana Estuary.

Baja California: Playas de Tijuana, including the Border Fence and the malecon. Playas de Rosarito, including Pemex complex at Rosarito Beach, pier at the Rosarito Beach Hotel, and the mouth of the creeks.
