Sentences with phrase «water column layers»

Warming temperatures in the Chesapeake Bay region's streams will have implications for future shifts in water quality, eutrophication and water column layers in the bay.

Not exact matches

After they die, their detritus slowly sinks from the surface to the sea floor, and there is a layer in the water column, the OMZ, where microbes consume much of the detritus, a process that depletes oxygen through bacterial respiration.

That's likely because the water column was still separated into distinct saltwater and mostly freshwater layers — and hadn't started turning over at high rates, Schmidt says.

Sea ice is critical for polar marine ecosystems in at least two important ways: (1) it provides a habitat for photosynthetic algae and nursery ground for invertebrates and fish during times when the water column does not support phytoplankton growth; and (2) as the ice melts, releasing organisms into the surface water [3], a shallow mixed layer forms which fosters large ice - edge blooms important to the overall productivity of polar seas.

The resulting weaker density stratification allowed more vertical mixing of the water column during storms in late September and early October, leading to the observed warming of the near - bottom layer in the still ice - free Laptev Sea... Warmer water temperatures near the seabed may also impact the stability of the shelf's submarine permafrost.»

Water columns are much more strongly stratified in the tropics than in higher latitudes, so it takes a lot less energy to move parcels from deep oceanic layers to the surface in high latitudes — and, not surprisingly, this is where most communication occurs between deep and surface waters.

The entire mass of the atmosphere column is equivalent to about 3 meters of sea water, only a fraction of the well - mixed layer.

A thunderstorm event might be best depicted as a run - away rising column of air that is becoming progressively warmer than the surrounding air as condensing water vapor yields its heat of vaporization until almost all water vapor has condensed out and then cooling at a rate of 9.8 deg C per 1000 meters, it eventually reaches a warmer layer of air and spreads out like smoke over a ceiling.

Depending on the method used to interpolate the data (along isopycnals or vertically by station), the estimated random uncertainty of the computed TC02 values in the Atlantic Ocean throughout the water column below the wintertime mixed layer depth ranges from ± 7.1 µmol / kg to ± 5.9 µmol / kg.

In the most recent observations from 2013 - 2014, the upper layers» compensatory variability has given way to warming over the entire water column from 0 — 2000 m.

Chesapeake Bay mainstem and Danish Straits are permanently stratified and trends were calculated for the surface layer (0 — 10 m), whereas trends in Southern North Sea and Tampa Bay represent the entire water column.

This methane is settling in a 200 - meter layer in the water column at a depth of 1,000 to 1,300 meters.
