Sentences with phrase «upwelled waters»

The phrase "upwelled waters" refers to the movement of deep, cold, nutrient-rich waters from the ocean's depths towards the surface. This process occurs due to wind and ocean currents, and it brings important nutrients to the upper layers, supporting the growth of marine life. Full definition
In general, the regions of expanding warming upwelling water in the Indian Ocean, North Pacific, or wherever they are, must create slight bulges in the surface, and the regions of shrinking, cooling, sinking water in the Arctic must create slight depressions in the sea surface (again, I mean in a very low pass sense — obviously storms, tides, etc, create all kinds of short - terms signals obscuring this).
Research shows that humpback diets reflect their surroundings, with the truck - sized whales filter - feeding on vast amounts of krill when cold upwelling waters prevail, but switching to schooling fish such as anchovies when warmer waters take over and the fish grow abundant.
And consistent with multidecadal variability, during the previous negative PDO from 1940 to the late 70s, corrosive upwelled waters had similarly reduced survival of larval oysters in those bays.
The picture I gave neglects the effect of ocean dynamics — cooling by upwelled water entering the mixed layer and warming by imported warm water from the side.
The development of the Antarctic Circumpolar Current forever altered the carbon biological pump by increasing upwelling in the southern oceans, and later along continental west coasts by cooling upwelled waters.
Nutrients come from upwelled water, and productivity is likely to be limited by nitrogen.
Under normal conditions upwelling of cold CO2 - rich water from depth leads to outgassing when upwelled water warms at the surface.
Biogenic calcification happens at much greater rates than dissolution, and such rapid repair mechanisms would be expected for an animal seeking low pH upwelled waters to graze.
Marine biological activity then transfers a bit more C to the deep ocean than cold, upwelling waters bring back up, such that the net sink to the deep ocean is about 1.6 GtC / yr, and much slower permanent removal in sediments.
But again Bednarsek set forth a scenario to blame anthropogenic CO2, arguing upwelled waters had been directly «acidified» by anthropogenic CO2.
More or less cold and nutrient rich upwelling water driving changing global climate and ecologies.
The smaller surface area means it can't transfer heat to the atmosphere as quickly and cold upwelling water on the opposite shore gets greater exposure so the atmosphere cools.
Sea butterflies prefer to graze in highly productive regions generated by nutrient rich but corrosive upwelled waters.
However the problem with this scenario is the source of upwelled waters along the California Oregon coast can be traced back to the California Undercurrent.
Upwelling water in various locations, including the west coast of North America (thats the USA) will be warmed from this absorbtion of energy.
Since the warmest waters are always near the surface, temperature spikes (El Nino) should be less apparent than the temperature dips due to the colder upwelling waters (La Nina), which can suppress heat transfer to the atmosphere.
Surface waters are moved away from the equator and replaced by upwelling waters.
A long - standing puzzle in ocean photosynthesis was why phytoplankton failed to grow fast in parts of the Pacific Ocean; after all, the microscopic plants have access to plenty of carbon dioxide thanks to upwelling water.
Because the upwelled waters ran along the surface for a longer period of time, nutrients spent more time near the surface of the ocean where phytoplankton could feed on them for longer.
Application of this model to time series data reiterates the direct association between low aragonite saturation state and upwelled waters and highlights the extent to which benthic communities on the Northern California shelf are already exposed to aragonite undersaturated waters.
Blue Whales (Balaenoptera musculus), Fin Whales (Balaenoptera physalus), and Sei Whales (Balaenoptera borealis) can be observed in the Channel Islands National Marine Sanctuary feeding on krill from the nutrient rich, upwelled water (late - May through September).
If the upwelling water is warmer, that will result in more warming of the adjacent land.
It may be decades or centuries before the final effect is felt from this warming, but the upwelling water is warmer now than it was 50 years ago from this effect.
To attribute her observed dissolution to anthropogenic CO2, Bednarsek argued recent invasions of anthropogenic CO2 into the surface water had lowered its surface pH to such an extent, mixing no longer counteracted the low pH of upwelled water.
Because winds will mix supersaturated surface waters with corrosive upwelled waters in the upper 200 meters, mixing can neutralize any corrosive effects of upwelled waters.
All stations experienced upwelling and Bednarsek acknowledged, «these upwelled waters are approximately 1000 years old».
She speculated the upwelled waters had been near the surface 50 years ago, during which time it equilibrated with the 1960s atmosphere.
Outside of coral reefs, other marine ecosystems also benefit from lower pH. For example diatoms now account for 40 % of the world's ocean primary productivity and flourish in upwelling waters that bring abundant CO2 and DIC from the ocean's dark depths into sunlit surface regions.
Upwelling waters are corrosive naturally, but their pH may decline further over time due to OA.
The very very slightly warmer temperature of the upwelling water isn't able to heat the atmosphere more than that.
Pumping power is derived from the solar energy stored in the ocean surface by means of a heat engine that uses the temperature differential between the surface water and the upwelled water.
