Cornish beach vanishes under wave of bizarre sea foam

Storm Aileen has battered the coastal county

Updated: 

This British beach appears to vanish under a sea foam mattress - that also sweeps up a tiny dog.

A dog walker captured the bubbly spume which blanketed the sand as a result of a natural weather phenomenon.

Maureen Lord, a retired health care assistant, said her pet Boston appeared "bemused" as foam lapped up around him on a walk, Cornwall Live reports.

The Truro, Cornwall, resident said the footage was taken before Storm Aileen battered the coastal county with heavy rain and blustery winds.

According to experts, spume is caused by the winds driving rough seas.

Although it may appear unpleasant the foam does not pose a risk to humans.

However it is suggested the residue should be cleared up quickly to prevent algae from deteriorating which could become a threat to public health.

Maureen said she had never seen so much of the "deep" foam and added Boston needed a bath when they returned home.

Amateur photographer Niki Willows recorded thick suds 'wobbling like jelly' in Porthtowan, 10 miles from Truro.

She said: "A little foamy in Porthtowan this morning - the beach is moving!

"Sea foam is decomposing organic matter, nothing nasty."

The foam is made from a cocktail of seawater dissolved salts, proteins and algae and any other dissolved organic matter picked up along the way.

The phenomenon is a regular sight on Cornish beaches.

The bizarre phenomenon is common on Cornish beaches

An explanation on America's National Ocean Service website reads: "Sea foam forms when dissolved organic matter in the ocean is churned up".

On its website, NOAA says: "If you scoop up some water from the ocean in a clear glass and look at it closely, you'll see that it's chock full of tiny particles.

"Seawater contains dissolved salts, proteins, fats, dead algae, detergents and other pollutants, and a bunch of other bits and pieces of organic and artificial matter. If you shake this glass of ocean water vigorously, small bubbles will form on the surface of the liquid.

"Sea foam forms in this way - but on a much grander scale - when the ocean is agitated by wind and waves.

"Each coastal region has differing conditions governing the formation of sea foams.

"Algal blooms are one common source of thick sea foams. When large blooms of algae decay offshore, great amounts of decaying algal matter often wash ashore. Foam forms as this organic matter is churned up by the surf".
