Since salt is (for these purposes) a conserved variable in the ocean, mean changes in salinity can only occur through fresh water addition.

Time to get back to the thread, have you any insights regarding Arctic air / ocean temperature or salinity changes?

Consistent with how I was reading things, pleasantly — barring some cautious hedging I'd made, based on the possibility that salinity could reflect mass changes, either when fresh water was added to the ocean via glacial melt or impoundment decreases (ocean mass increase) or via increased evaporation rates (ocean mass decrease).

Hatun et al. examined the possibilities that [i] a change in rain falling over the ocean (freshens the water) and evaporation (increases the salinity by removing water and leaving salt behind), [ii] increased salinity in the sub-tropical gyre (in the main part of the North Atlantic), [iii] increased salinity in the sub-polar gyre, or [iv] dynamical changes in the relative contributions from the two gyres could explain the high salinities in the in - flow regions.

There is so little understanding about how the ocean parses its response to forcings by 1) suppressing (local convective scale) deep water formation where excessive warming patterns are changed, 2) enhancing (local convective scale) deep water formation where the changed excessive warming patterns are co-located with increased evaporation and increased salinity, and 3) shifting favored deep water formation locations as a result of a) shifted patterns of enhanced warming, b) shifted patterns of enhanced salinity and c) shifted patterns of circulation which transport these enhanced ocean features to critically altered destinations.

Many of the surface currents of the world oceans (i.e., the ocean «gyres» which appear as rotating horizontal current systems in the upper ocean) are driven by the wind, however, the sinking in the Arctic is related to the buoyancy forcing (effects that change either the temperature or salinity of the water, and hence its buoyancy).

(For instance, changes in wind or salinity or seaweed, surface warming in regions (in) sensitive to OHC, perhaps the southern oceans or perhaps NH / SH with their different proportions of land, or variations in the frequency / amplitude of a known oceanic wobble.)

At constant salinity net O2 evolution never exceeded 0.5 mol l - 1 h - 1 while net CO2 uptake consistently averaged 3 mol l - 1 h - 1 for an apparent net production of 36 mg C m - 3 h - 1, which greatly exceeds the O2 changes and open ocean 14C estimates from the literature.

Spatial variability of the rates of sea level rise is mostly due to non-uniform changes in temperature and salinity and related to changes in the ocean circulation.

The study, published in the journal Global Change Biology, examined the impacts of rising ocean temperatures, changes in salinity and currents resulting from a warming climate.

Sea ice is an important component of the Earth system; it is highly reflective, altering the amount of solar radiation that is absorbed; it changes the salinity of the ocean where it forms and melts, and it acts as a barrier to the exchange of heat and momentum fluxes between the atmosphere and ocean.

Climate models also indicate a geographical variation of sea - level rise due to non-uniform distribution of temperature and salinity and changes in ocean circulation.

Following this delayed - mode correction, salinity errors are reduced further and in most cases the data become good enough to detect subtle ocean change.

The retreat of glaciers and shrinking of the Greenland ice sheet in the Arctic, for example, is predicted to cause significant sea - level rise, changes in the salinity of our oceans, and altered feedback loops that will make the Arctic warm up even faster.

Salinity changes within the ocean also have a significant impact on the local density and thus local sea level, but have little effect on global average sea level change.

To conduct the research, a team of scientists led by John Fasullo of the US National Center for Atmospheric Research in Boulder, Colorado, combined data from three sources: NASA's GRACE satellites, which make detailed measurements of Earth's gravitational field, enabling scientists to monitor changes in the mass of continents; the Argo global array of 3,000 free - drifting floats, which measure the temperature and salinity of the upper layers of the oceans; and satellite - based altimeters that are continuously calibrated against a network of tide gauges.

Chief among these claims is that the change in salinity in the North Atlantic ocean is responsible for the decadal fluctuations, not changes in the trade winds and mid-latitude westerlies (the IPO)- as suggested by Meehl et al (2011), Meehl et al (2013) and England et al (2014) for instance.

The issue is that differences in mineral content, salinity, density, and temperature all affect how the ocean reacts to, and drives, changes in weather patterns, climate variations over years or decades, ocean current circulation, etc..
