A Grain of Sand – Nature’s Secret Wonder, A Book By Dr. Gary Greenberg
Every grain of sand is a jewel waiting to be discovered. That’s what Dr. Gary Greenberg found when he first turned his microscope on beach sand. Author and photographer Dr. Gary Greenberg is a visual artist who creatively combines art with science. Since 2001, Dr. Greenberg focuses his microscopes on common objects, such as grains of sand, flowers, and food. These everyday objects take on a new reality when magnified hundreds of times, revealing hidden and unexpected aspects of nature. Dr. Greenberg’s images of sand make us realize that as we walk along a beach we are strolling upon thousands of years of biological and geological history…

Experiments show shifting ripple patterns can signal times of environmental flux.

When a coastal tide rolls out, it can reveal beautiful ripples in the temporarily exposed sand. These same undulating patterns can also be seen in ancient, petrified seabeds that have been exposed in various parts of the world and preserved for millions or even billions of years…

Bits of the Sahara on the Move

By Mike Carlowicz, NASA / Earth Observatory;

Scientists estimate that winds and storms pick up roughly 180 million tons of dust from the Sahara Desert each year and deposit it in the Atlantic Ocean and on the Americas. In the past week, active weather systems made a big deposit toward the 2018 total, as relentless storms lofted vast plumes of dust for days.

The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite acquired this series of natural-color images from March 22–25, 2018. Strong winds across North and West Africa lifted vast quantities of dust from the Sahara Desert and carried it over the Atlantic Ocean. The dust storm has continued for eight days, as visible in more images from March 26, March 27, March 28, and March 29.

Dust storms can pose breathing problems, create poor visibility, and lead to other health and safety concerns when these aerosols are concentrated near the ground. But when spread over long distances, the airborne dust can provide a natural fertilizer for plants and forests. For instance, the dust lofted from the Sahara has been shown by scientists to provide a significant amount of nutrients for the Amazon rainforest. Dust also can fertilize the ocean for phytoplankton blooms.

In late March 2018, winds associated with a series of low-pressure weather systems appeared to fuel the flow of dust across Africa. Dust storms are common in the Sahara in the springtime, as the weather changes with the seasons. However, multiple observers in the region described this week’s storms as particularly intense.

Hyams Beach, Australia: Beach with the whitest sand in the world

Excerpts;

The whitest sand in the world: it’s a claim to fame Hyams Beach on Australia’s New South Wales South Coast has enjoyed for years, even securing it a place in the Guinness World Records.

Luckily, even the most nitpicking visitor to Hyams cannot complain – the sand is indeed whiter than white and the only problem you may encounter is in the “on season” when you might have to head to the far end of the beach to spot enough patches of the famous grains between the bods on the shore…
