Algorithm finds missing phytoplankton in Southern OceanEurekAlert | 19 Sep 2013
(University of New South Wales) NASA satellites may have missed more than 50 percent of the phytoplankton in the Southern Ocean. But now, new research published in the Journal of Geophysical Research has led to the development of an algorithm that produces substantially more accurate estimates of Southern Ocean phytoplankton populations.
Online citizen scientists: Classify plankton imagesEurekAlert | 18 Sep 2013
Today, an online citizen-science project "Plankton Portal" launches, created by University of Miami Rosenstiel School of Marine and Atmospheric Sciences researchers with National Oceanic and Atmospheric Administration, National Science Foundation and developers at Zooniverse.org. Plankton Portal allows you to explore the open ocean from the comfort of your own home.
CO2-hungry microbes might short-circuit the marine foodwebEurekAlert | 16 Sep 2013
(Helmholtz Centre for Ocean Research Kiel (GEOMAR)) A five-week long field experiment of the European Project on Ocean Acidification shows that pico- and nanophytoplankton benefit from higher carbon dioxide concentrations in the water, causing an imbalance in the food web. In addition, the carbon export to the deep and the production of the climate-cooling gas dimethylsulfide are diminished -- two important functions for the global climate.
Climate change will upset vital ocean chemical cyclesEurekAlert | 09 Sep 2013
New research from the University of East Anglia shows that rising ocean temperatures will upset natural cycles of carbon dioxide, nitrogen and phosphorous. Plankton plays an important role in the ocean's carbon cycle by removing half of all CO2 from the atmosphere during photosynthesis and storing it deep under the sea.
Phytoplankton social mixersEurekAlert | 16 Jul 2013
(Massachusetts Institute of Technology) Scientists at MIT and Oxford University have shown that the motility of phytoplankton also helps them determine their fate in ocean turbulence.
Scientists Solve a 14,000-year-old Ocean MysteryWoods Hole Oceanographic Institution | 16 Jul 2013
At the end of the last Ice Age, as the world began to warm, a swath of the North Pacific Ocean came to life. During a brief pulse of biological productivity 14,000 years ago, this stretch of the sea teemed with phytoplankton, amoeba-like foraminifera and other tiny creatures, who thrived in large numbers until the productivity ended—as mysteriously as it began—just a few hundred years later.
Resourceful microbes reign in world's oceansEurekAlert | 26 Jun 2013
Using cutting-edge technology on a large scale for the first time, researchers led by Bigelow Laboratory for Ocean Sciences have discovered that marine microbes are adapted to narrow and specialized niches, a finding pivotal to detecting and mitigating human impacts in the ocean.
A Book Blooms in the LabWoods Hole Oceanographic Institution | 16 May 2013
When conditions of light and nutrients align in the surface waters of the ocean, tiny single-celled algae called phytoplankton respond with explosive growth and reproduction in a phenomenon known as a phytoplankton bloom.
Arctic expedition to study impact of climate change on planktonGuardian Unlimited | 14 May 2013
The goal of the 25,000km Tara Oceans Polar Circle Expedition, with some 15 scientist on board, is to search for planktonic organisms, including viruses, bacteria, protists and metazoans, all vital resources that need to be studied in their own environment while there is still time.
The Black Sea is a Goldmine of Ancient Genetic DataWoods Hole Oceanographic Institution | 07 May 2013
When Woods Hole Oceanographic Institution (WHOI) marine paleoecologist Marco Coolen was mining through vast amounts of genetic data from the Black Sea sediment record, he was amazed about the variety of past plankton species that left behind their genetic makeup (i.e., the plankton paleome).
Research Enables Fishermen to Harvest Lucrative Shellfish on Georges BankWoods Hole Oceanographic Institution | 16 Apr 2013
Combined research efforts by scientists involved in the Gulf of Maine Toxicity (GOMTOX) project, funded by NOAAs Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program, and administered by the National Centers for Coastal Ocean Science (NCCOS), have led to enhanced understanding of toxic algal blooms on Georges Bank.
Volcanic ash triggers plankton bloomBBC | 10 Apr 2013
The 2010 Icelandic volcanic eruption, which disrupted flights across Europe, also had a "significant but short-lived" impact on the North Atlantic, a study says.
Bloom: Photosynthetic pods for mid-ocean livingsmartplanet.com | 05 Apr 2013
Phytoplankton are microscopic organisms that float around the water surface, harnessing sunlight to make energy for themselves. Like plants, they use chlorophyll to produce oxygen while absorbing carbon dioxide. So, with impending sea level rises, French architecture firm Sitbon Architectes designed a livable, phytoplankton farm to be installed in the Indian Ocean.
Researchers Issue Forecast for 'Moderate' New England Red Tide in 2013Woods Hole Oceanographic Institution | 26 Mar 2013
New England is expected to experience a moderate red tide this spring and summer, report NOAA-funded scientists studying the toxic algae that cause blooms in the Gulf of Maine. The red tide is caused by an alga Alexandrium fundyense, which produces a toxin that can cause paralytic shellfish poisoning (PSP).
Ocean plankton sponge up nearly twice the carbon currently assumedEurekAlert | 18 Mar 2013
(University of California - Irvine) Models of carbon dioxide in the world's oceans need to be revised, according to new work by UC Irvine and other scientists published online Sunday in Nature Geoscience. Trillions of plankton near the surface of warm waters are far more carbon-rich than has long been thought, they found.
Glaciers a Major Source of Iron to North AtlanticWoods Hole Oceanographic Institution | 12 Mar 2013
All living organisms rely on iron as an essential nutrient. In the ocean, irons abundance or scarcity means all the difference as it fuels the growth of plankton, the base of the oceans food web. A new study by biogeochemists and glaciologists at Woods Hole Oceanographic Institution (WHOI) identifies a unexpectedly large source of iron to the North Atlantic – meltwater from glaciers and ice sheets.
Seafarers, science needs you! Help us collect data on the oceansGuardian Unlimited | 08 Mar 2013
If you are a sailor, angler or small boat owner and would like to take part in a unique global study of the health of the oceans then I need your help. My team of marine biologists and computer scientists at the University of Plymouth are aiming to recruit thousands of seafarers from around the world who are willing to collect simple data while out at sea and submit it to us via a free app - called Secchi.
Sailors to help measure planktonBBC | 23 Feb 2013
Researchers are asking sailors and fishermen to help with what they hope will be the world's biggest study of plankton in the oceans.
Climate change clues from tiny marine algae -- ancient and modernScienceDaily.com | 06 Feb 2013
Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago. The study found that their response to environmental change varies between species, in terms of how quickly they grow.
