Algal Blooms

Experiments that add iron to the sea have had mixed success, though, and may cause harmful algal blooms and ocean acidification.

Much is washed off by rain, ending up in local watercourses where dissolved nutrients can cause algal blooms and kill fish.

On a seasonal basis, algal blooms near the sea surface send pulses of organic material to the deep seafloor.

This can trigger toxic algal blooms and a rising number of oxygen deficient 'dead zones'.

So far, the rising sea levels, dying corals and spreading algal blooms are only minor distractions for most people.

This paper summarizes the relationships between the occurrences of harmful algal blooms and the eutrophication in coastal waters.

whether these spores represent telltale clues of toxic algal blooms, however, has yet to be confirmed.

"We've had enormous algal blooms here the last few years which have affected the whole ecosystem, " Westman said.

And occasionally, dinoflagellates create large algal blooms, known commonly as "red tide, " which poison many shellfish at once.

Algal blooms trigger by eutrophication due to Nitrogen runoff choke river ecosystems.

Harmful algal blooms that induced by lake eutrophication have caused serious problems to water ecosystem and human health.

He has located possible exits for such a channel, as well as tiny fossils of Mediterranean algal blooms formed in the past 10, 000 years.

In the United States, the government says harmful algal blooms cause more than eighty million dollars in economic losses each year.

Harmful algal blooms have increased in recent years, and the building of early observing and monitoring system is very difficult.

Long term problems with pollution has made Japanese scientists leading authorities on algal blooms.

Certain species of phytoplankton produce powerful biotoxins, making them responsible for so-called "red tides, " or harmful algal blooms.

The nutrients feed algal blooms, which suck up the oxygen in the water.

Bacteria consume most of the water's oxygen when they feast on the algal blooms attracted by these abundant nutrients.

Meanwhile, Lake Erie was widely declared "dead, " its waters contaminated by algal blooms.

Red tides or algal blooms are natural discolorations of seawater caused by the rapid multiplication of algae .

Instead we suffer ever more coastal "dead zones" overrun by nitrogen-fed algal blooms.

That could promote the growth of algal blooms which deplete oxygen in the water column.

These algal blooms create beautiful patterns that can stretch for hundreds of miles and trace the ocean's swirling currents.

Previous studies have shown that adding iron artificially can also create algal blooms.

Release of sediment phosphorus is also an outbreak of algal blooms in the required source of nutrients.

In fact, we have some tantalizing evidence that algal blooms occurred in the stagnant pools of water that drew the animals together.
