Due West: Malibu Coast, The
The Malibu coast is plagued by serious erosion problems-especially landslides. Given that coastal erosion is an unavoidable fact of life, the focus in this fabled community is not so much on stopping it, but finding ways to live with it. These inclu...
Due West: Aliso Creek
Aliso Creek, located in Orange County, California, has a consistent beach pollution problem due to rapid development of the upstream environment. As the watershed has been largely paved over, the water is prevented from soaking in and filtering natu...
Surf's Up: Shoreline Effects of Wind Wave Energy
Nearly all of the effects of wind wave energy are felt along the shoreline, often in the form of erosion. The erosion process on the shoreline moves sand from one place to another and, over time, actually changes the orientation of the coast.
Waste and Other Threats to Oceans and Marine Life
Explorer and environmentalist Jean-Michel Cousteau talks about the adverse effects of waste, heavy metals and other chemicals on the ocean and marine life.
On the Coast: Coastline Changes Over Time
Whatever a coastline's shape today, it was probably different yesterday, as it will no doubt be tomorrow. Coastal zones are among the most dynamic areas on Earth, subject to a host of factors that make every coast a work in progress.
The Ocean's Memory: Terrigenous Sediments
Sediment is the debris that accumulates on the surface of the Earth as the result of chemical, physical and biological processes. Most sediment, known as terrigenous sediment, forms when rain falls on soil and washes it into rivers, which then carry...
On the Coast: Protecting the Coastal Environment
Given the extensive use of the coast by humans, the task of protecting the coastal environment is enormously challenging.
