Sentences with phrase «tropical surface waters»

The main mechanism for wind - driven mixing into the deep ocean (down to around 2000 metres) is via convergence of warm tropical surface water in the subtropical ocean gyres.

Although kelp forests are unknown in tropical surface waters, a few species of Laminaria have been known to occur exclusively in tropical deep waters.

The Atlantic Meridional Overturning Circulation (AMOC)- the transport of warm tropical surface water northward - is indeed propelled by dense water sinking in the North Atlantic and travelling equatorward in the deeper layers, but it also has a wind - driven component to it.

The problem with the tropics is that if tropical surface waters are destined to remain at the surface for a while, they are also probably destined to ultimately scrounge the iron they need, to use the available nitrogen and phosphorus.

As the warm tropical surface waters travel poleward they encounter an equatorward flowing current created by the mid-latitude westerlies and this surface convergence causes the centre of the gyre to pile up water mass.

You may be familiar with part of this circulation, the Gulf Stream, which brings warm, tropical surface water northward along the East Coast of the United States and funnels toward the poles.

Ocean Thermal Energy Conversion (OTEC) uses the temperature difference between the warm tropical surface water and the cooler, deep water in the ocean to generate energy.

This means that, e.g., if heat moves from the tropical surface water (temp about 25C) to surface waters at lower temps, the net effect is a subsidence of sea level — even without any change in total heat content.

Tropical surface waters, one could argue, will still be at the surface a year from now, so there is plenty of time for them to replenish their CO2 concentration by sucking it out of the atmosphere.
