T-S diagram of a station in the North Pacific. In oceanography, temperature-salinity diagrams, sometimes called T-S diagrams, are used to identify water masses.In a T-S diagram, rather than plotting each water property as a separate "profile," with pressure or depth as the vertical coordinate, potential temperature (on the vertical axis) is plotted versus salinity (on the horizontal axis).
In the diagram pictured at the top, it categorises a water mass by the temperature and salinity of the water and is represented by a single point. However, water masses are not constant. Throughout time climates can change, seasons can drag out, or there could be less rainfall meaning that the water masses might change in temperature or salinity.
The tides, the Coriolis effect, changes in direction and strength of wind, salinity, and temperature are the main factors determining ocean currents. The thermohaline circulation (THC) (thermo-referring to temperature and -haline referring to salt content) connects the ocean basins and is primarily dependent on the density of sea water. It is ...
The temperature is −1.8 °C (28.8 °F), which is very near to the freezing point. This layer blocks heat transfer from the warmer, deeper levels into the sea ice, which has considerable effect on its thickness. About 150 m (490 ft) of steeply rising salinity and increasing temperature. This is the actual halocline.
The British Columbia Shore Station Oceanographic Program is a sea surface temperature and salinity monitoring program on the Canadian coast of the northeast Pacific Ocean. [1] The program is administered by Fisheries and Oceans Canada , and regroups 12 lighthouse stations in British Columbia .
The difference is that the density increases with depth, whereas the salinity and temperature decrease with depth. The halo-, thermo-, and pycnocline at 10E, 30S. For this image the annual means of the year 2000 from the GODAS Data [4] has been used. In the ocean, a specific range of temperature and salinity occurs.
Typically, warm freshwater is less dense than cold salty water, thus the colder water will sink below the warmer water. Isopycnals are used to display this vertical distribution of the water. Variations in temperature and salinity along isopycnals can be described with spiciness. This creates distinguishable layers of water with differing ...
Generally, vertical profiles are made of temperature, salinity, chemical parameters at a defined point along the water column. [1] The water column is the largest, yet one of the most under-explored, habitats on the planet; it is explored to better understand the ocean as a whole, including the huge biomass that lives there and its importance ...
