Harmful Algal Blooms monitored from space in Chile

...ing a growing world market. However, the country's marine aquaculture sector is vulnerable to Harmful Algal Blooms, which occur when some algae species producing poisons bloom rapidly in water, causing physical or biochemical damage to fish and shellfish. Early detection of Harmful Algal Blooms (HABs) all...

UCI scientists find chlorine may contribute to ozone formation

...n said. "Most likely the process involves airborne marine particles, but research is needed to understand how it occurs." Inland ozone levels typically are higher than on the coast, mainly because of meteorological conditions that restrict air circulation and trap pollutants. Ozone is a highly reactive and...

Arctic coring expedition continues to yield new clues

...wet during the PETM," Dickens said. "Even tropical marine plants thrived in the balmy conditions." In today's oceans, certain species of microscopic plants are known to rapidly multiply and create algal blooms. Dickens said that fossils of these plants ?known only to originate in the tropics before the P...

A new look at the state of the oceans

...much higher than previously thought. Especially in marine systems, the term 'diversity' not only describes the distinction between biological species, but also refers to the divergence within established species. This leads to a completely new evaluation of the species concept. For the recording and descrip...

They used statistical methods to correlate the bacteria counts with the Wrigley Institute's monthly measurements of water temperature, salinity, nutrient content, plant matter and other variables. The researchers f...

Pollution threatens coral health by preventing lesions from healing, UCF study shows

...isk of McMaster University in Ontario, Canada, and marine ecologist Brian LaPointe of the Harbor Branch Oceanographic Institution in Fort Pierce. Risk and LaPointe used ratios of stable isotopes of nitrogen as tracers of sewage levels. Higher values equate to larger amounts of sewage in an area. Risk and La...

Study reveals details of mussels' tenacious bonds

When it comes to sticking power, marine mussels are hard to beat. They can adhere to virtually all inorganic and organic surfaces, sustaining their tenacious bonds in saltwater, including turbulent tidal environments. Little is known, however, about exactly how the bivalves achieve this am...

Ammonia-loving archaea win landslide majority

...ammonia. The gene was subsequently found in a marine strain of archaea that uses ammonia as its sole source of energy. Researchers examined soil samples from 12 pristine and agricultural lands across three climatic zones to see if such ammonia-oxidizing microorganisms were present in terrestrial ecosys...

On the track of tiny larvae, a new model elucidates connections in marine ecology

...ent Biology, published by Cell Press. Effective marine management and conservation planning require a better understanding of the movement of young marine animals, including small larvae, in part because such movements facilitate normal biological connect...
