Microbial communities in seawater from an Arctic and a temperate Norwegian fjord and their potentials for biodegradation of chemically dispersed oil at low seawater temperatures — Deni Ribicic — Marine Pollution Bulletin

Not exact matches

The fish are then placed in an ice slurry that is one part seawater and three parts freshwater, which draws blood and rapidly lowers the temperature of the fish to around 32 degrees, preserving the flesh.

The results show that blue crabs can — at moderate water temperatures — survive at oxygen levels as low as 1.3 milligrams per liter, just 15 % of the oxygen available in fully saturated seawater.

But laboratory studies have shown that the process can be disrupted, and shells can dissolve, as seawater becomes more acidic, or lower in pH. (Temperature has an impact, too.)

Beck interpretes the latter as the direct influence of seawater temperatures, but the measurements near the floating ice border were just average, not the lowest... Modern measurements give less than 10 ppmv difference over the seas from the coldest oceans to the tropics, including a repeat of the trips that Buch made.

The open cycle consists of the following steps: (i) flash evaporation of a fraction of the warm seawater by reduction of pressure below the saturation value corresponding to its temperature (ii) expansion of the vapor through a turbine to generate power; (iii) heat transfer to the cold seawater thermal sink resulting in condensation of the working fluid; and (iv) compression of the non-condensable gases (air released from the seawater streams at the low operating pressure) to pressures required to discharge them from the system.
