Sentences with phrase «of dead plankton»

When enough of these carbonate deposits build up, they form carbonate rocks, such as limestone, which are composed of the skeletons of trillions of dead plankton.

Now the flood is supposed to have happened about 4361 years ago (2013)[1] so that means that if we go down that number of layers we should find on or about that layer evidence of the flood in the form of dead plankton, salt, and other ocean detritus.

Not exact matches

The plankton that feed on the dust's minerals can bloom significantly, providing food for other ocean creatures, but an overgrown bloom can consume much of the dissolved oxygen in an area and create an anoxic dead zone.

That muck, researcher Henry Ruhl says, is actually food — a nourishing blend of feces and dead plankton that fall from surface waters.

At the same time, this dead plankton can become a source of carbon that is not otherwise readily available to other sea life.

a) Satellite image showing fast disintegration of sea ice over a polar continental shelf; b) Zoobenthos on an Antarctic continental shelf; c) Examples of sea mosses (specimens on the left are from an open - water location and hence have had more plankton to feed on); and d) Dead bryozoan and other benthic skeletons covering the seabed, most likely to be buried, sequestering their blue carbon in the seabed.

CaCO3 tends to dissolve in the deep ocean, both because of the high pressure and because the waters have been acidified by CO2 from rotting dead plankton.

It is now well accepted and verified that many biological organisms (e.g., trees, corals, plankton, animals) alter their growth and / or population dynamics in response to changing climate, and that these climate - induced changes are well recorded in past growth in living and dead (fossil) specimens or assemblages of organisms.

Of far greater concern than corals in particular is the ocean food chain in general, because while acidification will probably result in more oceanic dead zones as the amount of CO2 goes up and the amount of oxygen falls, if you kill off the plankton and pteropods that use carbonate to make their shells, then you kill off the food supply for the vast majority of higher organisms (like mollusks, fish, and even marine mammalsOf far greater concern than corals in particular is the ocean food chain in general, because while acidification will probably result in more oceanic dead zones as the amount of CO2 goes up and the amount of oxygen falls, if you kill off the plankton and pteropods that use carbonate to make their shells, then you kill off the food supply for the vast majority of higher organisms (like mollusks, fish, and even marine mammalsof CO2 goes up and the amount of oxygen falls, if you kill off the plankton and pteropods that use carbonate to make their shells, then you kill off the food supply for the vast majority of higher organisms (like mollusks, fish, and even marine mammalsof oxygen falls, if you kill off the plankton and pteropods that use carbonate to make their shells, then you kill off the food supply for the vast majority of higher organisms (like mollusks, fish, and even marine mammalsof higher organisms (like mollusks, fish, and even marine mammals).

Hundreds of meters below the sea floor, bacteria produce methane from the dead plankton.

But some algae and plankton blooms can turn dangerous, either through the production of chemical toxins or by severely depleting the oxygen supply in the ocean and creating «dead zones» that suffocate marine creatures.
