Current increases in anthropogenic carbon dioxide emissions and related ocean acidification trends have parallels in an event 55 million years ago.

The Census of Marine Life Published on: 5th October, 2016 | Marine Science

The Census of Marine Life was the largest survey of our oceans to date, involving an international effort to catalogue all known marine life over 10 years: around 6,000 new species were identified, equivalent to about one and half for every day of the program.

The ocean is the worlds largest ecosystem. Human influences are fundamentally changing the oceans which many countries rely on for economic revenue and food. The process of ocean acidification and global warming have the potential to decimate the ocean ecosystem, giving little time to adapt.

Researchers from Marine Scotland have uncovered unusual bacteria, coral and anemones on the seabed. The unusual ecosystem is thought to have occurred because of a process of ‘cold seap’ where gas from deep in the earth, leaks onto the seabed creating an environment capable of supporting rare species

The floor of the Antarctic ocean is brimming with life. Some of these micro organisms, phytoplankton and bryozoans may be working together to act as a carbon sink slowing climate change.

The Galápagos is renowned for its unique wildlife and for having inspired Charles Darwin to develop his theory of evolution. A recent expedition has provided the first detailed assessment of the archipelago’s deep water seamounts and marine life.

The symbiosis between microalgae and corals is well understood – however the life cycle of the microalgae before they form this symbiosis is still being explored and may be more vulnerable than previously thought.

The final results of recent surveys into the extent of the 2015/2016 coral bleaching of the Great Barrier Reef have been released. The results are from extensive aerial and underwater surveys.

Divers are familiar with coastal and island marine ecosystems but what is there to see in the open ocean? Very rarely, a unique set of circumstances create vast free floating ecosystems as bizarre as they are diverse.

Zap! Have you ever touched a numb ray? Published on: 17th February, 2016 | Marine Science

In most dive locations you should “take only photographs, leave only bubbles”, and not touch the wildlife. However, many divers have accidentally received a shock on touching a numb ray. So what are these creatures?
