About 31 percent of the world’s coastlines are sandy. Africa has the highest proportion of sandy beaches (66 percent) and Europe has the lowest (22 percent). Researchers found that beaches in Australia and Africa have experienced more erosion than growth. The opposite is true on all other continents, where beaches are generally growing…

A mourning orca mother carried her dead baby for days through the ocean

A grieving mother orca near Vancouver Island has been carrying her dead calf for four days, after refusing to leave her baby behind when the rest of her pod left. The sad display speaks to something deeper. Killer whales eat salmon, and a number of human practices, such as damming rivers, have taken a toll on native salmon populations.

Big Talbot Island’s Blackrock Trail; By Cecelia Dailey

June 1st, 2019

The locals call it “lava beach”—a misnomer which leads some to believe the unique formation found here are igneous in origin. But these mystifying “black rocks” crumble to the touch, staining the hands, feeling gritty with sand. Although many are black, these “rocks” are sometimes light colored, deep red or burnt brown.

The geologic history of California’s north coast is evident in the typically steep relief and coastal landforms. This is an area where a drive along much of the narrow lanes of State Highway One along the often steep coast is always an adventure and where it’s never wise to take your eyes off the road for very long. Most of the beaches occur at the mouths of the coastal streams.

California’s Coastal Harbors, Beach Compartments and Sand Dredging; By Gary Griggs

October 1st, 2018

Every year the dredge at the Santa Cruz Small Craft Harbor along central California’s northern Monterey Bay sucks up about 250,000 cubic yards of sand, on average, from the entrance channel and pumps it out onto Twin Lakes Beach where it continues its journey down coast. If it were put in dump trucks, it would fill about 25,000 of them, but the waves can move all that sand without any human labor, and without any noise or carbon emissions.
