Scientists Create Global Atlas On Oceanic Plankton
2013-07-19 10:05:40

April Flowers for redOrbit.com - Your Universe Online An international group of scientists has created a global atlas of oceanic plankton -- from bacteria to krill -- by recording times, places and concentrations of the organism's occurrences. Over 70 percent of the world's surface is covered by the oceans. Compared with terrestrial ecosystems, the animals and plant species of the oceans have been researched relatively little. Because of this, the knowledge base concerning the...

Ancient Algal Bloom Mystery Solved
2013-07-15 15:05:24

Brett Smith for redOrbit.com - Your Universe Online An ancient bloom of life that occurred just after the last ice age isn't what it seemed at first, according to new research in the journal Nature Geoscience. Scientists had long believed that the bloom, which occurred around 14,000 years ago, was spurred by rising sea levels washing iron into the ocean. However, the new study suggested that a "perfect storm" of conditions allowed for the bloom to happen, and not simply the abundance of...

Phytoplankton Ocean Turbulence Social Mixers
2013-07-15 12:58:35

[Watch the video: Phytoplankton Social Mixers] Lee Rannals for redOrbit.com - Your Universe Online The motility of phytoplankton allows the tiny ocean plants to determine their fate in ocean turbulence, according to scientists at MIT and Oxford University. Researchers wrote in the journal Nature Communications that the individual vortices that make up ocean turbulence are like social mixers for phytoplankton. This social mixer brings similar cells into close proximity, helping to...

Oceans Of The Past Give Clues To The Future
2013-06-15 05:39:41

April Flowers for redOrbit.com - Your Universe Online The oceans of the past were quite different than the ones we see today. Ocean temperatures are increasing due to global warming, and these increases are harming marine food webs. Coastal dead zones are also being created by the run-off from fertilizers. An international team of researchers, led by McGill University, has completed the first global study of changes that occurred during the nitrogen cycle at the end of the last ice age....

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...

Researchers Uncover Genetic Payload Of Ancient Plankton In Black Sea Sediments
2013-05-07 10:23:32

April Flowers for redOrbit.com - Your Universe Online Sorting through the vast amounts of genetic data from the Black Sea sediment record, Woods Hole Oceanographic Institution (WHOI) marine paleoecologist Marco Coolen was astounded by the variety of past plankton species that left behind their genetic makeup. This vast amount of data is called the plankton paleome. The Black Sea is semi-isolated from other bodies of water, and highly sensitive to climate driven environmental changes....

Microorganisms In Sea Spray Alter Ability Of Ocean To Seed Clouds
2013-04-23 11:09:06

April Flowers for redOrbit.com - Your Universe Online The ability of sea spray to form clouds over the ocean is influenced by ocean biology which alters the chemical composition of the spray. A team of scientists from the University of California, San Diego, is using a new approach to study tiny atmospheric particles called aerosols. These aerosols can influence climate by absorbing or reflecting sunlight and seeding clouds. "After many decades of attempting to understand how the ocean...

Smartphone App Allows Seamen To Track Phytoplankton For Science
2013-02-24 08:08:54

redOrbit Staff & Wire Reports - Your Universe Online Researchers at the Plymouth University Marine Institute have developed a new smartphone app that they claim will allow regular folks to help scientists track the impact of climate change on phytoplankton. In a statement released Friday, the university reports that scientists are concerned that the tiny organisms, which are at the bottom end of the marine life food chain, could be decreasing in numbers due to increasing sea...

Scientists Analyze Costs And Benefits Of Rock Dissolving Practices
2013-01-22 12:14:08

Brett Smith for redOrbit.com - Your Universe Online Geoengineering is a controversial and illegal practice that attempts to mitigate the forces of climate change on a grand scale. Many see this attempt to alter global climate via artificial means as a ℠quick fix´ with potential long-term negative effects. However, despite the contentious nature of geoengineering, scientists from the Alfred Wegener Institute in Bremerhaven, Germany decided to analyze a ℠rock...

Chilean Sea Urchin, Loxechinus albus
2013-01-28 14:52:23

Image Caption: Chilean Sea Urchin, Loxechinus albus. Credit: Dentren/Wikipedia (CC BY-SA 3.0) The Chilean sea urchin (Loxechinus albus) is a species that can be found along the coastlines of Chile and Peru. It is typically found in shallow waters at or below the tide level, buried in sand or lying just on top of it. This species is often associated with Macrocystis pyrifera, a type of kelp. It is most often found in more open spaces. The Chilean sea urchin can reach an average width of...
