Sentences with phrase «ocean density»

As a result, the effects of global warming or global cooling on ocean densities are complex, and still poorly understood.

Johnston and Lambeck (1999) concluded that a solution consistent with geological evidence, including constraints on sea level for the past 6,000 years (Section 11.3.1), is for a non-steric sea level rise (i.e., not resulting from ocean density changes) of 1.0 ± 0.5 mm / yr for the past 100 years, with 5 to 30 % originating from Greenland melting.

Thermohaline circulation, also known as the ocean's conveyor belt, refers to the deep ocean density - driven ocean basin currents.

Seawater is compressible, so that we need to account for it when considering ocean density at depth.

Indeed, this complex dependence of ocean density on both temperature and salinity is believed to be one of the main drivers of the ocean circulation, as redistribution of more dense and less dense sea water leads to various different «thermohaline circulations» patterns.

To determine SL steric, we integrate ocean density to a depth of 900 m.... — Eric Leuliette

Sea level rise is comprised of two components: mass change due to melting ice and steric sea level rise due to changes in ocean density.

•» According to Zhang (2007) thermal expansion in the lower latitude is unlikely because of the reduced salt rejection and upper - ocean density and the enhanced thermohaline stratification tend to suppress convective overturning, leading to a decrease in the upward ocean heat transport and the ocean heat flux available to melt sea ice.

It is particularly motivated by the uncertainties in projections of ocean heat uptake, global - mean sea - level rise due to thermal expansion and the geographical patterns of sea - level change due to ocean density and circulation change.

Once they drain in summer, the sudden release of fresh - water stratifies the very surface water which then traps more heat at the surface (takes more work by the wind to mix it down against the ocean density gradient) which then leads to fast melting of what's left of the drained pond.
