Oceans cover over 70% of our “blue” planet and are vital to its health. For instance carbon moves in and out of the ocean and can be stored there for thousands of years. Oceans are also a source of food and livelihood to millions of people, and to the economies of coastal countries. They are also the largest habitable space on the planet and house many different organisms.

But there’s a great deal that scientists still don’t know about the world’s oceans.

Proposed mining of seabed could destroy unstudied ecosystems and disrupt vital carbon-storing functions, says naturalist

Sir David Attenborough has urged governments to ban deep sea mining, following a study warning of “potentially disastrous” risks to the ocean’s life-support systems if it goes ahead.

The study, by Fauna and Flora International (FFI), warns proposed plans to mine the seabed could cause significant loss of biodiversity, disruption of the ocean’s “biological pump”, and the loss of microbes important for storing carbon. The process, requiring machines operating thousands of metres under the sea, could also create plumes of sediment that smother areas far from the mining sites and kill wildlife.

A creature so rare that it has only a few recorded sightings across the world has been caught on camera by stunned scientists.

The benthic siphonophore, which looks like a single animal, is actually a “floating city” of many smaller organisms working together.29

We know a lot about how carbon dioxide (CO2) levels can drive climate change, but how about the way that climate change can cause fluctuations in CO2 levels? New research from an international team of scientists reveals one of the mechanisms by which a colder climate was accompanied by depleted atmospheric CO2 during past ice ages.
