If you stick your foot in cold water, touching a hot surface with your hand will hurt less.

When the researchers switched the electric current off by deoxygenating the water, thereby removing the electron acceptor at the sediment surface, the depth of the hydrogen sulfide layer in the sediment rose in less than an hour, as deeper microbes could no longer consume it.

Smaller, dispersed droplets are less threatening for two reasons: they present more surface area to the water, so ocean bacteria can degrade the oil faster; plus, the small droplets are much slower to rise to the surface, keeping the oil at sea instead of in coastal wetlands and giving the bacteria more time to do their magic.

Here, the long time series shows that the surface water layers became up to 1.5 per mill less saline during the measurement period.

The particles could have acted like a shield, blocking out the sun and preventing some radiation from evaporating water on the planet's surface, resulting in even less rainfall.

Water that collects in valleys underneath the ice sheet, in the Gamburtsev Mountains, refreezes when it passes under thinner parts of the ice sheet that are less insulated from cool surface temperatures.

Slower, less energetic ones indicate the amount of hydrogen lurking within a meter of the surface, and on the moon, hydrogen is a proxy for water.

Four of these new planets are less than 2.5 times the size of Earth and orbit in their sun's habitable zone, defined as the range of distance from a star where the surface temperature of an orbiting planet may be suitable for life - giving liquid water.

«By midcentury, we expect to see less reliable surface water supplies in several regions of the United States,» said the study's lead author, Kristen Averyt, associate director for science at the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder.

This makes water droplets less attracted to the feather's surface.

«The weaker overturning circulation brings less naturally CO2 - rich deep waters to the surface, which limits how much of that gas in the deep ocean escapes to the atmosphere.

Warming surface waters, however, absorb less oxygen.

If so, it diffused into the water more quickly than it spread across its surface, and if not, it diffused less quickly than it spread.

Around smaller, less massive and dimmer dwarf stars, however, planets would have to orbit closer in order to sustain a surface temperature that is warm enough to keep water liquid and so the star would appear larger in the sky.

As less radiation reaches the surface, the atmosphere may become more stable and clouds more persistent than usual, and less water will evaporate from the surface, a finding corroborated by Qian's China study.

If these polar continents lose a mile or more of ice from their land surface, there will be less mass, and so some of the water now attracted to those polar land masses will dissipate, and go elsewhere.

One explanation (ix) conceived in the 1980s invokes more stratification, less upwelling of carbon and nutrient - rich waters to the surface of the Southern Ocean and increased carbon storage at depth during glacial times.

The warming of the oceans by sunlight, makes the daytime surface waters more bouyant than the cooler waters below and this leads to stratification - a situation where the warmer water floats atop cooler waters underneath, and is less inclined to mix.
