Scientists are investigating impact of oil spill on vibrios and their antibiotic association with phytoplankton Mississippi Sound. Port Fourchon. Cocodrie. Three places among dozens in the Gulf of Mexico where oyster beds have thrived. How are the oysters faring with the oil spill? The National Science Foundation (NSF) has awarded a rapid response grant to scientists Crystal Johnson, Gary King and Ed Laws of Louisiana State University (LSU) to find out. The researchers will look at how the...

Computer simulations performed by researchers at the National Oceanography Centre and the University of Glasgow show how oceanic stirring and mixing influence the formation and dynamics of plankton patches in the upper ocean. Tiny free-floating marine plants called phytoplankton live in vast numbers in the sunlit upper ocean. Through the process of photosynthesis, they build carbon compounds such as sugars starting with just water and carbon dioxide, which is thereby drawn down from the...

Acidity is increasing in some regions of the Chesapeake Bay even faster than is occurring in the open ocean, where it is now recognized that increased levels of atmospheric carbon dioxide dissolve in the seawater thereby making it more acidic. These more acidic conditions in key parts of Chesapeake Bay reduce rates of juvenile oyster shell formation, according to new research published in the journal Estuaries and Coasts. The study, conducted at the University of Maryland Center for...

Inputs of dust from the Sahara desert could change the composition of microbial communities in the (sub)tropical eastern North Atlantic say Southampton researchers writing this month in the journal FEMS Microbiology Letters. When high winds blow over the Sahara, dust particles consisting of soil particles are lifted high into the atmosphere, blown over the sea, and then deposited on the ocean surface. "Desert dust particles contain nutrients such as iron that can boost the production of tiny...

A team of researchers from the UK's National Oceanography Centre will be spending the next month investigating how recent eruptions of an Icelandic volcano have effected marine life in the North Atlantic, according to a Thursday BBC News report. Earlier this month, eruptions at a volcano located beneath the Eyjafjallajokull glacier in southern Iceland covered the area with volcanic dust and created an ash cloud that crippled European air travel for the better part of a week. Now, the research...

Carbon fixation by phytoplankton in the open ocean plays a key role in the global carbon cycle but is not fully understood. Until now researchers believed that cyanobacteria overwhelmingly accounted for phytoplankton's role in carbon fixation in the open ocean. But now scientists at the University of Warwick and the National Oceanography Centre in Southampton have opened 'the black box' of eukaryotic phytoplankton and discovered that they actually account for almost half the ocean's carbon...

Acantharian cyst sedimentation Spore-like reproductive cysts of enigmatic organisms called acantharians rapidly sink from surface waters to the deep ocean in certain regions, according to new research. Scientists suspect that this is part of an extraordinary reproductive strategy, which allows juveniles to exploit a seasonal food bonanza. The research shows that deep sedimentation of cysts during the spring delivers significant amounts of organic matter to the ocean depths, providing a...

Results of Northwest Atlantic Field Program Could Be Applied Worldwide A three-year field program now underway is measuring carbon distributions and primary productivity in the Northwest Atlantic Ocean to help scientists worldwide determine the impacts of a changing climate on ocean biology and biogeochemistry. The study, Climate Variability on the East Coast (CliVEC), will also help validate ocean color satellite measurements and refine biogeochemistry models of ocean...

Pumping nutrient-rich water up from the deep ocean to boost algal growth in sunlit surface waters and draw carbon dioxide down from the atmosphere has been touted as a way of ameliorating global warming. However, a new study led by Professor Andreas Oschlies of the Leibniz Institute of Marine Sciences (IFM-GEOMAR) in Kiel, Germany, pours cold water on the idea. "Computer simulations show that climatic benefits of the proposed geo-engineering scheme would be modest, with the potential to...

One of the main objectives of marine biology is to understand the trophic food chains involving microbian plankton. That is, to study the sequence of organisms in relation to their nutrition, given that live organisms can be classified from the perspective of nutrition. In this classification each organism is at one level and all these levels are united one to the other, forming a chain. In this succession of stages or levels an organism feeds itself and is devoured. The structure of this...

Chilean Sea Urchin, Loxechinus albus

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
