Profile: Gary Griggs

Director of Marine Sciences

Gary Griggs' research is focused on the coastal zone and ranges from coastal evolution and development, through shoreline processes, coastal hazards and coastal engineering, and sea level rise. Recent research projects have focused on documenting and understanding coastal erosion processes including temporal and spatial variations in rates of retreat; evaluating the effectiveness of coastal protection structures and the impacts of coastal engineering projects (seawalls, jetties, breakwaters) on coastal processes and beaches; evaluating beach processes and quantifying littoral cell budgets and human impacts on these budgets; impacts of extreme events such as El Ninos) on coastlines; the impacts of sea-level rise on California's beaches and coastline; and coastal policies to reduce the impacts of hazards and sea-level rise.
He has published 180 articles in scientific journals and written or co-written 8 books

How Do You Measure Sea Level, Anyway?

There are about 330 million cubic miles of water in the world oceans today, 97% of all the water on the planet. Early in our planet’s 4.5 billion year history, water from the atmosphere and from the interior of the Earth gradually collected in the low areas on the planet’s surface to form the ocean basins, accumulating salts along the way.
The level of the ocean around the Earth, and therefore the location of the shoreline, are directly related to the total amount of water in the oceans, and also closely tied to climate. As climate changes, so does sea level.
