A change in pH by 0.1 represents a 26% increase in hydrogen ion concentration in the world's oceans (the pH scale is logarithmic, so a change of one in pH units is equivalent to a tenfold change in hydrogen ion concentration). Sea-surface pH and carbonate saturation states vary depending on ocean depth and location.

The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about −2 °C (28 °F). [1] The coldest seawater still in the liquid state ever recorded was found in 2010, in a stream under an Antarctic glacier: the measured temperature was −2.6 °C (27.3 °F). [2]
Redfield’s analysis of the empirical data led to him to discover that across and within the three oceans and Barents Sea, seawater had an N:P atomic ratio near 20:1 (later corrected to 16:1), and was very similar to the average N:P of phytoplankton. To explain this phenomenon, Redfield initially proposed two mutually non-exclusive mechanisms:
Or intrusion of seawater increases the chemical concentration of water. Water is too saline to be drinkable. [47] Saline 10000-36000 Similar to seawater. Strong evaporation of groundwater or fully mixing with seawater. Hyper-Saline 36000-100000 Strong evaporation on seawater or groundwater under a closed system. Brine >100000
The decreasing saturation of seawater with respect to calcium carbonate, associated with ocean acidification, a result of increased carbon dioxide (CO 2) absorption by the oceans, poses a significant threat to marine calcifiers. As CO 2 concentrations in seawater rise, a decrease in pH and a reduction in carbonate ion concentrations in seawater ...
In an appearance on "The Pacman Jones Show," the Hall of Famer and Colorado coach made it clear what he thinks the future holds for his son.
His work was extrapolated to other HNLC regions through evidence which linked low surface iron concentration with low chlorophyll. [6] In response to iron fertilization experiments (IronEx, SOIREE, SEEDS, etc.) in HNLC areas, large phytoplankton responses such as decreased surface nutrient concentration and increased biological activity were ...
