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.

II) An equilibrium between seawater and planktonic nutrient pools is maintained through biotic feedback mechanisms. [1] [3] Redfield proposed a thermostat like scenario in which the activities of nitrogen fixers and denitrifiers keep the nitrate to phosphate ratio in the seawater near the requirements in the protoplasm.

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]
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
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 ...
In the Cotton Bowl, bettors like Ohio State WR Jeremiah Smith to score a TD (-125). Smith has scored two touchdowns in each of Ohio State’s two playoff games and has 13 catches for 290 yards ...
[2] [3] [4] Pelagic life decreases as depth increases. The pelagic zone contrasts with the benthic and demersal zones at the bottom of the sea. The benthic zone is the ecological region at the very bottom, including the sediment surface and some subsurface layers. Marine organisms such as clams and crabs living in this zone are called benthos ...
