Brown tide stunts oyster growth
2014-09-08 02:00:19

Kim Martineau, Columbia University Lamont-Doherty Earth Observatory Close-Up Look at Genome May Lead to New Ways to Combat Harmful Blooms The sea-grass beds of Long Island’s Great South Bay once teemed with shellfish. Clams, scallops and oysters filtered nutrients from the water and flushed money through the local economy. But three decades after the algae that cause brown tides first appeared here, much of the sea grass and the bounty it used to provide is gone. Spring on eastern...

How Does Red Tide Knock Out Its Competition?
2014-06-05 03:05:40

By Brett Israel, Georgia Institute of Technology New research reveals how the algae behind red tide thoroughly disables – but doesn't kill – other species of algae. The study shows how chemical signaling between algae can trigger big changes in the marine ecosystem. Marine algae fight other species of algae for nutrients and light, and, ultimately, survival. The algae that cause red tides, the algal blooms that color blue ocean waters red, carry an arsenal of molecules that disable...

A new study on the feeding habits of ocean microbes calls into question the potential use of algal blooms to trap carbon dioxide and offset rising global levels. These blooms contain iron-eating microscopic phytoplankton that absorb C02 from the air through the process of photosynthesis and provide nutrients for marine life. But one type of phytoplankton, a diatom, is using more iron that it needs for photosynthesis and storing the extra in its silica skeletons and shells, according to an...

Carbon Dioxide Absorption In Antarctic Seas Studied
2013-06-13 09:39:28

Georgia Institute of Technology The seas around Antarctica can, at times, resemble a garden. Large-scale experiments where scientists spray iron into the waters, literally fertilizing phytoplankton, have created huge man-made algal blooms. Such geoengineering experiments produce diatoms, which pull carbon dioxide out of the air. Experts argue that this practice can help offset Earth´s rising carbon dioxide levels. However, the experiments are controversial and, according to a new...

Impact From Humans Felt On Black Sea Long Before Industrial Era
2012-09-04 14:44:23

When WHOI geologist Liviu Giosan first reconstructed the history of how the Danube River built its delta, he was presented with a puzzle. In the delta´s early stages of development, the river deposited its sediment within a protected bay. As the delta expanded onto the Black Sea shelf in the late Holocene and was exposed to greater waves and currents, rather than seeing the decline in sediment storage that he expected, Giosan found the opposite. The delta continued to grow. In fact,...

North Atlantic Phytoplankton Bloom Triggered By Eddies
2012-07-06 05:16:57

redOrbit Staff & Wire Reports - Your Universe Online Scientists studying the annual growth of tiny plants in the North Atlantic Ocean have discovered that this year´s growth spurt began before the sun was able to offer the light needed to fuel the yearly phenomenon. The annual growth spurt of plankton, which is known as the North Atlantic Bloom, takes place each Spring, and results in an immense number of phytoplankton bursting into existence -- first "greening," then...

Discovery could lead to new methods for environmental remediation and speeding up chemical reactions A glow coming from the glassy shell of microscopic marine algae called diatoms could someday help us detect chemicals and other substances in water samples. And the fact that this diatom can glow in response to an external substance could also help researchers develop a variety of new, diatom-inspired nanomaterials that could solve problems in sensing, catalysis and environmental...
