It's extremely clear water, because there's hardly any plankton.

But since we ate all the oysters and we ate all the fish that would eat the plankton, there's nothing to eat the plankton and there's more and more of it, so it dies of old age, which is unheard of for plankton.

It might be a change in the distribution of plankton.

Bacterioplankton refers to the bacterial component of the plankton that drifts in the water column.

It runs down the rivers, and it feeds the plankton, the little microscopic plant cells in the coastal water.

And yet, if you look at whale sharks, which is the other plankton eating large shark, its diversity is much greater.

The dolphins eat the fish that have PCBs from the plankton, and those PCBs, being fat soluble, accumulate in these dolphins.

The lake water is fresh, with a low transparency of about 2.5 m due to plankton and suspended sediments caused by the river flow.

In 2002, in the central Pacific gyre, there were found to be six kilograms (kg) of plastic for every kilogram of plankton near the surface.

And it's been suggested that basking sharks would make fantastic indicators of climate change, because they're basically continuous plankton recorders swimming around with their mouth open.

But just to try to prove that fact to you, I've brought along some bioluminescent plankton in what is undoubtedly a foolhardy attempt at a live demonstration.

So, if we could have the lights down and have it as dark in here as possible, I have a flask that has bioluminescent plankton in it.

The findings were unexpected as it was previously believed that the plankton grows only after the seasonal ice melt, yet some algae was discovered under several metres of intact sea ice.

And fertilizers and pesticides are flowing into the bay from the golf course the pesticides killing all the larvae and little animals, fertilizer creating this beautiful plankton bloom and there's your pea soup.

It is generally accepted that oil is formed mostly from the carbon rich remains of ancient plankton after exposure to heat and pressure in the Earth's crust over hundreds of millions of years.

We see the base of the food chain, the plankton, the small things, and we see how those animals are food to animals in the middle of the pyramid, and on so up this diagram.

Research vessels a fisheries research vessel (FRV) requires platforms which are capable of towing different types of fishing nets, collecting plankton or water samples from a range of depths, and carrying acoustic fish finding equipment.

And sometimes you can see it even closer than that, because the heads on ships that's toilets, for any land lovers that are listening are flushed with unfiltered seawater that often has bioluminescent plankton in it.

And in the spring, when the sun returns to the ice, it forms the phytoplankton, grows under that ice, and then you get bigger sheets of seaweed, and then you get the zoo plankton feeding on all that life.

The chalk itself's composed by plankton which has fallen down from the sea surface onto the sea floor, so that 90 percent of the sediment here is skeleton of living stuff, and then you have that millimeter thick red layer, and then you have black rock.
