Sentences with phrase «ocean floor microbes»

Finding that limit — the goal of the 62 - day T - Limit campaign, part of the International Ocean Discovery Program — could guide estimates of the abundance and diversity of ocean floor microbes, which play large roles in biogeochemical cycles.

Not exact matches

But the vents, which are rich in energy sources for microbes, are poor proxies for most ocean floor sediments, where scarce nutrients could mean a lower thermal limit.

In deeper parts of the ocean, the methane released from the ocean floor would likely never make it up to the atmosphere, since it would get used up by microbes before it reached the surface.

Samples from a mud volcano contain biological signatures that suggest microbes lived in the material when it was rock several kilometres beneath the ocean floor

Many researchers believe iron - metabolizing microbes might have turned plentiful dissolved iron into minerals, which then settled out of seawater and deposited along the ocean floor.

Samples from a mud volcano contain biological signatures that suggest microbes lived in the material when it was several kilometres beneath the ocean floor.

Field observations of microbes recovered from deep drill cores, deep mines, and the ocean floor, coupled with laboratory investigations, reveal that microbial life can exist at conditions of extreme temperatures (to above 110ºC) and pressures (to > 10,000 atmospheres) previous thought impossible.

Over a year ago, scientists uncovered a microbe that lives in hot - water geysers on the ocean floor near Iceland.

New keys to understanding the evolution of life on Earth may be found in the microbes and minerals vented from below the ocean floor, say scientists at the University of California, Santa Barbara.

Human activities account for 60 percent of methane emissions, but other contributors include plumes from frozen ocean floors, microbes, abandoned wells and even beavers of all things.

Jeffrey Marlow, from the Division of Geological and Planetary Sciences at the California Institute of Technology, and colleagues have found that the towering rocks lying at the ocean floor and near methane seeps, are the dwellings of methane - munching microbes.

Between 6 and 22 percent of the Earth's methane comes from seeps in the ocean floor but most of these do not get into the surface nor released into the atmosphere because microbes consume up to 90 percent of this.
