Sentences with phrase «other ocean sediment»

The dates on two other ocean sediment cores (Stott et al 2004 — # 14 and # 15) are on the correct scale thankfully, but are still marginal in terms of resolution (29 and 44 years respectively, but effectively longer still due to bioturbation of the sediments).

These samples augment other marine records such as coral and seashells, which provide detailed records over a short time period, and deep - ocean sediments, which preserve thousands of years of history but are harder to date precisely.

Other hostile conditions deep in ocean sediments, such as scarce nutrients, high pressure, or extreme salinity, probably set life's limit in some places.

This time Becker, Basu, and four other coauthors described a submarine hump called Bedout High that is buried in ocean sediments 100 miles off the northwest coast of Australia.

Other papers in the issue examine how deep sea sediments may affect seismic wave readings, and evaluate how the Cascadia Initiative's data collection from ocean bottom seismometers has improved over the first three years of the study.

There are other proxies, such as tree rings or ocean sediments, but their messages have to be decoded and interpreted by scientists.

Tides, storms and other disturbances in shallow water will stir up the bottom, while further from shore, where the water is deeper, turbulence can not reach the ocean floor, allowing sediment to settle undisturbed.

The increased wave action reaches down and stirs up sediments on shallow continental shelves, releasing radium and other chemicals that are carried up to the surface and swept away into the open ocean by currents such as the Transpolar Drift.

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.

In most places in the world's oceans, microbes consume all the oxygen less than 10 centimeters into the sediment and below that depth switch to using other compounds for respiration.

An analysis of sediment from 17 seabed sites — from European estuaries to the Great Barrier Reef in Australia and the deep Atlantic Ocean — found that the bathyal region of the Rockall Trough has more species than any other area so far measured.

Carbonic acid dissociated to form hydrogen ions, which found their way into the structures of weathering minerals, and bicarbonate, which was carried down rivers and streams to be deposited as limestone and other minerals in ocean sediments.

In addition, they are now extending MOSART to simulate how sediment, carbon and other nutrients move from the landscape through the rivers and into the ocean.

Microorganisms dominate all other life everywhere scientists have looked, including the human body, the Earth's soils and sediments, the oceans and fresh waterways, the atmosphere and even extreme environments such as hydrothermal vents and subglacial lakes.

Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when the Earth's atmosphere began to contain oxygen, according to researchers from the U.S., Canada and Japan.

While this view has been changing for some time, a revolution in our thinking came with the discovery of Lokiarchaeum («Loki») and other members of the «Asgard» clade of archaea through metagenomic sampling of ocean sediments in 2015.

The team also correlated their findings with other studies of California climate history, and for the first time, cross-referenced these with histories of the Pacific Ocean's temperature taken from marine sediment cores and other sources.

[15] Through study of Pacific Ocean sediments, other researchers have shown that the transition from warm Eocene ocean temperatures to cool Oligocene ocean temperatures took only 300,000 years, [11] which strongly implies that feedbacks and factors other than the ACC were integral to the rapid cooOcean sediments, other researchers have shown that the transition from warm Eocene ocean temperatures to cool Oligocene ocean temperatures took only 300,000 years, [11] which strongly implies that feedbacks and factors other than the ACC were integral to the rapid cooocean temperatures to cool Oligocene ocean temperatures took only 300,000 years, [11] which strongly implies that feedbacks and factors other than the ACC were integral to the rapid cooocean temperatures took only 300,000 years, [11] which strongly implies that feedbacks and factors other than the ACC were integral to the rapid cooling.

If there is — say some combination of other elements adding to produce a better structure for the «cage» of water molecules that trap methane, say occurring naturally in pore spaces in sediment or leaf litter washed into the ocean — it ought to be discoverabe.

I think the ice core is considered the most reliable, especially in terms of better temporal resolution, than the other proxies from ocean sediment.

Examinations of paleoclimate temperatures and other variables recorded in both North Atlantic ocean sediments and Greenland ice cores (e.g., Lehman and Keigwin, 1992; Alley et al., 1993; Taylor et al., 1993) have led to suggestions that the AMOC

They found that the dense, salty water from the Marmara Sea — which leads out to the Aegean and Mediterranean Seas at the other end of the Bosphorus — is flowing out of the strait and along the bottom of the Black Sea, carrying along sediment and nutrients that could be key in providing vital nutrients to remote parts of the ocean.
