What is Conductivity?
UPDATE : Fondriest Environmental is offering their expertise in conductivity through their new online knowledge base. This resource provides an updated and comprehensive look at conductivity and why it is important to water quality. To learn more, check out: Conductivity, Salinity and TDS. 
 
 
 Salinity and conductivity measure the water's ability to conduct electricity, which provides a measure of what is dissolved in water. In the SWMP data, a higher conductivity value indicates that there are more chemicals dissolved in the water. 
 
Conductivity measures the water's ability to conduct electricity. It is the opposite of resistance. Pure, distilled water is a poor conductor of electricity.

For as long as humans have inhabited Europe’s Atlantic coast, the ocean has been a great source of wonder and mystery. History is full of fascinating tales of epic endeavors, new discoveries of fearless explorers, fishing communities inextricably linked to the bounties of the sea, cultural interactions both peaceful and not, and voyages that went awry during monumental storms or simply due to bad luck. 
 
In the south of Spain, at the boundary between the Atlantic Ocean and the Mediterranean Sea, one such tale involves a long-lost merchant ship that went undiscovered from the 16th century until 1984. Believed to be carrying valuable goods from Italy, it sank just across from Gibraltar in the Algeciras Bay at a point called La Ballenera.

While we usually concern ourselves with budgeting money or time, we should be thinking about another type of budget: the carbon budget. The carbon budget refers to the amount of carbon exchange, especially carbon dioxide, allotted on an annual basis to prevent the earth from reaching an increase of 2-degrees Celsius all over the globe. If a 2 degree increase does occur, global warming effects are expected to be catastrophic and irreversible. 
 
In order to know how close we are to reaching the carbon budget, an extensive knowledge of types of carbon input and their magnitudes, as well as their fluctuations over time, is needed.
