Marine aquarist's concern

Usage examples of salinity.

The phytoplankton cells were too small to be killed by the two-hundred-foot drop from the belly of the bombers, but no one was willing to bet that the Ulva would not be destroyed by sudden changes in salinity, temperature, or air pressure.

North American continent, we would have expected merely to confirm that the salinity of that ocean is about the same as average oceanic salinity in the Holocene, but that oceanic oxygen content is low, barely a third of the Holocene.

Sometimes, particularly in the lower Tigris and Euphrates valleys, soil salinity restricts the area of arable land and limits the size of the community dependent on it, and it also usually results in large unsettled and uncultivated stretches between the villages.

As floodwater spills over the glass walls, temperature, salinity, pH and oxygen levels go haywire.

The phytoplankton cells were too small to be killed by the two-hundred-foot drop from the belly of the bombers, but no one was willing to bet that the Ulva would not be destroyed by sudden changes in salinity, temperature, or air pressure.

In both parts of this section there are, as shown in Fig. 3, two great volumes of water, from the surface down to depths greater than 500 metres, which have salinities between 35.

The fact that the water on the banks off the coast has lower salinities, and in part lower temperatures, than the water outside in the deep sea, has usually been explained by its being mixed with the coast water, which is diluted with river water from the land.

This is clearly seen on the chart, which shows the distribution of temperatures and salinities on the surface.

But below these depths the temperatures and salinities decrease rather rapidly for some distance.

It appears that the salinities at the Planet station, in any case to a depth of 400 metres, were lower, and in part much lower, than those of the Fram Expedition.

In this way the upper zones of water become mixed, and acquire almost equal temperatures and salinities.

Yet it was not when Oakes was on duty that Jack, leaning over the side with Adams to measure the salinity, heard a voice float down from the fore crosstrees in answer to the cry 'Don't you know you must pass the selvagee first, damn your eyes?

The external forces acting on it--the currents, the ocean waves, the salinity of the water and its resultant density, tides, the Coriolis effect, the strains on the tugboat lines, winds, rainfall, vapor pressure, atmospheric pressure, propeller vibration, the heat of the sun--dozens of factors--are even more complex.

Jack, who as usual was making what observations were possible - observations of temperature atvarious depths, salinity, humidity of the air and so on for his friend Humboldt - showed Stephen his sea-chest, which had been brought up on to the half-deck so that the joiner might add an additional till or tray, a very stout chest indeed, that had seen and survived almost every kind of weather the world could offer: but the harmattan had split its lid - a broad cleft from one end to the other.
