CRU Information Sheet no. 7: Thermohaline circulation
The density of sea water is controlled by its temperature (thermo) and its salinity (haline), and the circulation driven by density differences is thus called the ... warming and an artificially imposed collapse of the thermohaline circulation. The map shows differences in temperatures simulated for the 2050s and those that occurred prior to industrilaisation ...

Oceans
Deep ocean currents are generated by the sinking and upwelling of water, due to density differences driven by temperature and salinity (saltiness) contrasts. A well known and important surface ocean current ...

Celsius. Cold slows down the movement of water molecules and their density increases. As water gets colder the hydrogen bonds override the motion of the molecules and ... as it freezes causing the molecules to grow farther apart. The decrease in density causes ice to float. Density differences between different masses of seawater are one of the major driving forces of ...

Ane Zubizarreta Gerendiain, Heli Peltola, Pertti Pulkkinen, Veli-Pekka Ikonen & Raimo Jaatinen. 2008. Differences in growth and wood properties between narrow and normal crowned types of Norway ... growth and yield and fibre length, but lower wood density. Moreover, the phenotypic correlations between growth, yield, wood density traits and fibre properties, ranged, on average, from moderate ...

Jyske, Tuula, Mäkinen, Harri & Saranpää, Pekka. 2008. Wood density within Norway spruce stems
Only small differences (3–6%) in wood density were found between different heights in the stem. The largest (49–80%) variation in wood density was found within the annual rings. The difference in wood density ...
