The influence of atmospheric composition on the climates of present-day and early Earth has been studied extensively, but the role of ocean composition has received less attention.

Scientists reveal a new part of the recipe for complex life on planets, and it involves the onset of a microbial fertilizer factory on the Earth's seafloor roughly 2.6 billion years ago.

The deep-ocean floor is the least explored ecosystem on the planet, despite covering more than 60% of the Earth surface.

One Sea To Many Oceans

The Labrador Sea between Canada and Greenland is often referred to as a 'lung of the deep ocean' because it is one of only a handful of locations worldwide where oxygen from the atmosphere can enter the deepest layers of the ocean.

By drilling deep down into sediments on the ocean floor researchers can travel back in time. A research team led from Uppsala University now presents new clues as to when and why a period often referred to as the 'biogenic bloom' came to an abrupt end. Changes in the shape of the Earth's orbit around the Sun may have played a part in the dramatic change.

In the strange, dark world of the ocean floor, underwater fissures, called hydrothermal vents, host complex communities of life.

New research may provide a breakthrough for scientists to understand life in the harshest of environments.

On May 14, the National Oceanic and Atmospheric Administration (NOAA) ship Okeanos Explorer will depart from Port Canaveral in Florida on a two-week expedition led by NOAA Ocean Exploration, featuring the technology demonstration of an autonomous underwater vehicle.

Oxygen is essential for the development of higher life. However, it was hardly present in the oceans of the young Earth. It was not until the evolution of photosynthetic bacteria that the oceans saw a significant increase in oxygen levels.

A team led by University of Minnesota researchers has discovered that deep-sea bacteria dissolve carbon-containing rocks, releasing excess carbon into the ocean and atmosphere.
