I believe this Tsunami Debris is directly in the path of migrating whales to Alaska… From BBC http://www.bbc.co.uk/news/world-us-canada-18349741
Tapping into the Ocean By Nikolay Voutchkov Seawater desalination produces fresh, low-salinity potable water from seawater via membrane separation or evaporation. The mineral/salt content of the water is usually measured by the water quality parameter total dissolved solids (TDS), in milligrams per liter (mg/L) or parts per thousand (ppt). The World Health Organization and the […]
Measuring ocean water salinity Measuring salinity Most meters measure the electrical conductivity of water. Batteries are connected to two wires (electrodes). Salty water will conduct electricity between the two electrodes, the saltier the water, the more electricity is conducted. The unit of electrical measurement used is Siemens. The meter we use in the field measures […]
Seawater at a practical salinity of 35 has a conductivity of 4.29 Siemens m-1 at 15°C or 2.904 S m-1 at 0°C.
Of course this Seawater Composition is from Wikipedia Total Molar Composition of Seawater (Salinity = 35) Component Concentration (mol/kg) H2O 53.6 Cl− 0.546 Na+ 0.469 Mg2+ 0.0528 SO2− 4 0.0282 Ca2+ 0.0103 K+ 0.0102 CT 0.00206 Br− 0.000844 BT 0.000416 Sr2+ 0.000091 F− 0.000068

I found this a good definition of a Marine Biologist. But, it is one of many… http://www.wisegeek.com/what-is-a-marine-biologist.htm A marine biologist is usually a person with advanced degrees in life sciences. He or she will study life forms of the ocean from a scientific perspective, and may hold specific bachelors, masters, or PhDs in biology, marine […]
Different science overview There are some good data presentations here: http://www.appinsys.com/globalwarming/OceanAcidification.htm A student definition??? Definition: Acidic: containing or having the properties of an acid, “Pertaining to substances that have a pH lower than 7” [http://www.biology-online.org/dictionary/Acidic]. While the term acidification refers to decreasing pH, the term acidic is only valid when the pH is less than […]
