These bacteria may «fix» as much nitrogen as all previously known ocean organisms combined.

Not exact matches

We don't know how the same organisms got to be in both places, because South African crust has not seen ocean water in two - and - a-half billion years.

In 1998, a bot known as ROPOS («Remotely Operated Platform for Ocean Science») sawed a black smoker free from the sea floor and hauled it up to allow scientists to examine its structure and unique organisms.

and Organisms had about 50 million years to get good at making hard materials in the ocean based on, you know, trial and error and using what's in their environment, and we don't have 50 million years.

We know life evolved in the oceans... but many of the organisms we studied are uncharacterized, little known to science, and we have a lot of work to do understand where these organisms fit in in our understanding of life.»

In the April 12 issue of the journal Science, Lutz and co-author Paul Falkowski, a professor in Rutgers's departments of Geological Sciences and Marine and Coastal Sciences, point out that the handful of samples taken thus far from the ocean's depths have introduced scientists to new strains of an anaerobic bacteria known as actinomycetes, which Lutz calls «fascinating organisms with profound medical possibilities.»

Mollusks, we learn, make up an enormously diverse phylum of organisms — an estimated 85,000 known species, with thousands more waiting in the ocean and in museum collections to be described.

These organisms are important because they churn up sediments from the bottom of the ocean, a process known as «bioturbation», playing a vital role in returning nutrients to surrounding water as food for other creatures.

Some of this naturally released methane comes from the ocean, a phenomenon that has long puzzled scientists because there are no known methane - producing organisms living near the ocean's surface.

A well - known issue with LGM proxies is that the most abundant type of proxy data, using the species composition of tiny marine organisms called foraminifera, probably underestimates sea surface cooling over vast stretches of the tropical oceans; other methods like alkenone and Mg / Ca ratios give colder temperatures (but aren't all coherent either).

Did you know that there are single - celled organisms that produce up to 90 % of the Earth's oxygen, help purify the ocean, are the food source for some of the longest - living species on the planet and can reproduce multiple times per day?

The potential for marine organisms to adapt to increasing CO2 and the broader implications for ocean ecosystems are not well known; an emerging body of evidence suggests that the impact of rising CO2 on marine biota will be more varied than previously thought, with both ecological winners and losers.

If you knew anything about geology or chemistry you would know that an increase in the concentration of CO2 in the world's oceans makes the oceans acidic, which will eventually make the oceans uninhabitable by certain organisms whose niche is within the natural pH of the oceans.

A science teacher pointed out to me that those little organisms that live near the deep ocean vents will no doubt carry on living here.)

For even if the models are proven to be wrong with respect to their predictions of atmospheric warming, extreme weather, glacial melt, sea level rise, or any other attendant catastrophe, those who seek to regulate and reduce CO2 emissions have a fall - back position, claiming that no matter what happens to the climate, the nations of the Earth must reduce their greenhouse gas emissions because of projected direct negative impacts on marine organisms via ocean acidification.

as it was previously said here, it won't prevent acidification of oceans but such molecules like sulphates are known to provoke acidic rains, and even atmospheric pollution for some sensitive organisms like lichens.
