The Oceans

Microscopic arms race rages on the seabed

The ocean floor contains viruses and bacteria locked in a constant struggle for survival. This has a great effect on the carbon cycle in the ocean and thus also affects how much CO2 is released into the atmosphere.

The cleaners of the sea

When we humans change the chemistry of the sea, it’s up to the very smallest organisms to clean up after us. The question is whether they can cope with it.

Surprisingly few major Ice Ages in southwest Greenland

The waters off southwest Greenland have escaped extremely large and thick ice sheets during most of the Ice Ages, new research reveals.

Singing bowhead whales give new insight into behaviour

Of the estimated 12 species of baleen whale, only the song of the humpback and bowhead whale covers both low and high frequency areas. A researcher has looked into this mystery.

Overlooked life on seabed gorges on fish faeces

Bacteria are not the only organisms that feed on dead plankton and fish faeces. The so-called ‘archaea’ also play an important – and hitherto overlooked – role in carbon cycling in the seabed.

Sea snakes break rules of evolution

Evolutionarily speaking, sea snakes are some pretty weird creatures. They have evolved both large and small heads very quickly and apparently without being separated geographically.

Oceans drive climate change

Researchers say that changes in the climate can be traced in the ocean hundreds of years before there is any trace of it in the atmosphere.

Bacteria thrive at the bottom of the Mariana Trench

Scientists have found bacteria in one of the world’s most hostile and extreme environments 11 km below sea level.

Live bacteria found deep below the seabed

Scientists have found live microbial communities in the earth’s crust deep below the seabed. The discovery may affect our conception of Earth's orbit.

Fish migrate to avoid predators

Tagged fish reveal that animals migrate to avoid being eaten by predators.
