🌊 The Big Foam Party of “Barbara” Yesterday at the Tel Aviv Port 🥳
It looked as if all the dish soap from every restaurant at the port had spilled into the sea, right?
So what is sea foam, actually? 🌊
If you take a glass of ocean water and look at it closely, you’ll see it’s full of tiny particles.
Seawater contains dissolved salts, proteins, fats, dead algae, and plenty of organic material.
If you shake that glass of seawater vigorously, you’ll notice small bubbles forming on the surface – just like soap foam.
That’s exactly what happens in the ocean.
Under stable conditions, these substances create foam near the shore that disappears quickly (called “sea spray”).
But when extreme weather conditions occur – strong winds combined with powerful waves – those organic materials get churned up, trapping air and forming persistent bubbles that stick together.
Because of the low density and rapid formation, the foam can pile up along the shore and even be blown inland by strong winds.
So, is it pollution or a fascinating natural phenomenon? 🌀🌬️⛽🚨
Sea foam is a global phenomenon, and it varies depending on the location and environmental conditions at the time.
Most of the time, sea foam is harmless to humans and often indicates a rich and productive marine ecosystem.
However, events such as algal blooms, sewage discharge, oil pollution, or excessive brine discharge from desalination plants increase the amount of organic matter in the water – which can lead to large amounts of sea foam even without major storms.
Unfortunately, the sewage infrastructure and wastewater treatment systems of the Tel Aviv metropolitan area aren’t capable of handling the heavy rainfall from storms like “Barbara.”
So there’s a good chance that quite a bit of sewage and urban runoff reached the sea – playing a not-so-minor part in yesterday’s massive foam party we all witnessed at the Tel Aviv Port. 🌊
