Scientists Red Queen evolutionary principl microbes waters off Southern California
2019/12/20
In the waves off Southern California, germ warfare occurs in a struggle as old as life itself. That's where University of Southern California marine biologists recently completed a comprehensive new s...
Red seaweeds, including those in sushi, thrive despite ancestor's loss of genes（图）
Red seaweeds ancestor loss of genes
2019/11/5
You'd think that losing 25 percent of your genes would be a big problem for survival. But not for red algae, including the seaweed used to wrap sushi.Red algae include phytoplankton and seaweeds, also...

近日，中国地质大学地球科学学院和生物地质与环境地质国家重点实验室宋海军教授团队在自然子刊《Nature Communications》上发表题为“The onset of widespread marine red beds and the evolution of ferruginous oceans”的学术论文，阐述了地质历史时期海相红层的时空分布规律和形成机制，揭示了38亿年以来海洋铁含量的...
When certain types of algae accumulate at the ocean surface in high numbers, they turn large swaths of water a reddish-brown color, attracting attention for both good and bad reasons.Off the coast of ...
Coastal Ocean Physics and Red Tides:An Example from Monterey Bay, California
Coastal Ocean Physics Red Tides Example from Monterey Bay California
2015/7/27
Dense accumulations of certain phytoplankton make the ocean appear reddish. Some of these "red tides" poison marine life and negatively impact coastal fisheries and human health. Complex variability i...
Aerosolized Florida Red Tide Toxins and Human Health Effects
Aerosolized Florida Red Tide Toxins Human Health
2015/7/23
Reports of airway irritant effects from Florida red tide have been documented since 1844 (Baden et al., 2005). In general, it is well established that persons inhaling marine aerosols containing polye...
Contrasting Bays and Red Tides in the Southern Benguela Upwelling System
Southern Benguela Upwelling System Red Tides
2015/7/21
In late summer and autumn of 2007, red tides were present in two prominent bays of the southern Benguela upwelling system, False Bay and St. Helena Bay. In False Bay, the dinoflagellate Gonyaulax poly...
The off-shelf region between 16.0° and 16.5°N in the southern Red Sea is identified as a new hotspot for the occurrence of oceanic internal solitary waves. Satellite observations reveal trains of soli...
Increased cellular brevetoxins in the red tide dinoflagellate Karenia brevis under CO2 limitation of growth rate: Evolutionary implications and potential effects on bloom toxicity
Increased cellular brevetoxins Karenia brevis
2014/4/2
Karenia brevis blooms impair human health, marine ecosystems, and coastal economies in the Gulf of Mexico
via their production of carbon-based neurotoxins (brevetoxins), which contain no nitrogen (N)...

California, is described in high spatial and temporal resolution using novel instrumentation inc...
Marine Scientists Warn of "Moderately Large" Potential for Spring, Summer Red Tide Outbreak in Gulf of Maine（图）
Moderately Large Gulf of Maine Spring Summer
2009/4/30
The potential for an outbreak of the phenomenon called "red tide" is expected to be moderately large this spring and summer in the Gulf of Maine, according to researchers at the Woods Hole Oceanograph...
Seasonality of N2 fixation and nifH gene diversity in the Gulf of Aqaba (Red Sea)
N2 fixation nifH gene diversity
2014/4/17
Nitrogen (N2) fixation rates were determined on bulk water collected in the Gulf of Aqaba, Red Sea, during
fall (stratified, oligotrophic) and spring (deep mixing, mesotrophic) seasons. N2
fixation ...
The Relationship between Water Mass Formation and the Surface Buoyancy Flux, with Application to Phillips’ Red Sea Model
Water Mass Formation Surface Buoyancy Flux Red Sea Model
2008/12/12
A buoyancy flux across the sea surface between the outcropping of isopycnals must be balanced by a subsurface diapycnal buoyancy flux. If this flux were only advective, its derivative with respect to ...
Climatological Coastal Jet Collision, Intermediate Water Formation, and the General Circulation of the Red Sea
Red Sea General Circulation
2008/11/24
The authors present climatologies of a numerical model of the Red Sea, focusing on the dynamics of winter intermediate water formation. Northward flowing boundary currents are identified as the major ...
The heat and freshwater transports through the Strait of Bab el Mandab, connecting the Red Sea with the open ocean, are reviewed and used to test air–sea fluxes from a revised version of the Comprehen...
