Webb10 apr. 2024 · Floating ice (b) displaces an equivalent mass of seawater, and so the melting of floating ice does not induce a mass change in the ocean, but it does produce a drop in salinity. This leads to a very small (generally negligible) GMSLR due to the reduction of seawater density and consequent increase in ocean volume (Noerdlinger … WebbFrom (2.4.1), a seawater sample of Reference Composition whose Practical Salinity PS is 35 has a Reference Salinity RS of 135.165 04 g kg− . Millero et al. (2008a) estimate that the absolute uncertainty in this value is 10.007 g kg−± . …
