A monstrous 75-foot wave was recorded about 20 miles off the coast of Cape Mendocino in northern California, according to the University of California, San Diego’s Coastal Data Information Program…

Excerpts;

When lightning strikes the beach or desert, the electricity vaporizes the sand in less than a second, creating a geological phenomenon you might have to see to believe.

The sand vaporizes as the lightning bolt shoots through the surface and creates temperatures of 50,000 degrees Fahrenheit, then the explosion turns the sand to glass tubes called fulgurites…

A wider, deeper beach awaits Ocean City vacationers, but is it safe? The Washington Post (06-01-2018)
Ocean City vacationers may notice deeper, wider beaches, the result of a $282 million sand-dredging project aimed at protecting the resort town from storm damage. But the work also raises concerns about surf injuries and swimmer safety…

Widening beaches might bring more hazards, researchers say; Sun Sentinel (04-04-2018)
Widening beaches might be linked to an increase in accidents, according to new data. The number of ocean rescues spikes after beaches are buffed up, according to the data published in the Journal of Ocean Research…

Why This Treacherous Hawaiian Beach, Keeps Breaking People’s Necks, The Washington Post (10-27-2015)
Adding new sand didn’t merely widen the beaches, they found — it made them higher, “resulting in steep slopes that can cause large waves to break close to shore. In other words, replenishment was doing to Delaware’s beaches what nature long ago did to Hawaii’s Sandy Beach…

Scientists map huge undersea fresh-water aquifer off U.S. Northeast

Excerpts;

In a new survey of the sub-seafloor off the U.S. Northeast coast, scientists have made a surprising discovery: a gigantic aquifer of relatively fresh water trapped in porous sediments lying below the salty ocean. It appears to be the largest such formation yet found in the world.

The aquifer stretches from the shore at least from Massachusetts to New Jersey, extending more or less continuously out about 50 miles to the edge of the continental shelf. If found on the surface, it would create a lake covering some 15,000 square miles.

The study suggests that such aquifers probably lie off many other coasts worldwide, and could provide desperately needed water for arid areas that are now in danger of running out…

Salty water causes some freshwater harmful algae to release toxins; USGS (10-18-2018)
The finding suggests that understanding the mixing of fresh and salt water, which takes place in many coastal water bodies around the world, will help researchers understand the toxic effects of these harmful algal blooms…

Excerpts;

Most diamonds are made of cooked seabed. The diamond on your finger is most likely made of recycled seabed cooked deep in the Earth. Traces of salt trapped in many diamonds show the stones are formed from ancient seabeds that became buried deep beneath the Earth’s crust (NetBet.org Australia), according to new research…
