Centers for Marine Renewable Energy in Europe and North America
Marine renewable energy wave tidal current power wave energy
2015/7/7
Since the late 1990s, there has been increased interest in marine renewable energy, such as wave and tidal current. Wave and tidal current energy has the potential to supply 15% of the UK's electricit...
Technological Challenges to Commercial-Scale Application of Marine Renewables
Marine renewable energy high waves tidal power energy density the ocean thermal power generation
2015/7/7
Marine renewable energy has many attractive qualities, including high energy densities for ocean wave and tidal power generation, and a high capacity factor for ocean thermal power generation. However...
Reduction of dimethylsulfoxide to dimethylsulfide by marine phytoplankton
dimethylsulfoxide dimethylsulfide marine phytoplankton
2014/4/18
Dimethylsulfoxide (DMSO) is an abundant but poorly understood methylated sulfur compound in the marine environment. One potentially significant loss pathway for DMSO is through its biological reductio...
Calcium carbonate precipitation induced by the growth of the marine cyanobacterium Trichodesmium
Calcium carbonate precipitation marine cyanobacterium Trichodesmium
2014/4/17
In this laboratory study, we monitored the buildup of biomass and concomitant shift in seawater carbonate
chemistry over the course of a Trichodesmium bloom under different phosphorus (P) availabilit...
Variations in the optical properties of a particle suspension associated with viral infection of marine bacteria
Variations particle suspension associated marine bacteria
2014/4/17
A laboratory experiment was conducted to examine the temporal dynamics of the particle size distribution
(PSD) and associated optical variability caused by viral infection of marine heterotrophic bac...
Scavenging and retention of bismuth by marine plankton and biogenic particles
Scavenging retention bismuth marine plankton biogenic particles
2014/4/17
We did radiotracer experiments using207 Bi to quantify the bioavailability, accumulation, and retention of bismuth in marine plankton and biogenic detritus. The accumulation of207Bi by two species of ...
Oscillatory porewater bioadvection in marine sediments induced by hydraulic activities ofArenicola marina
Oscillatory porewater bioadvection marine sediments hydraulic activities of Arenicola marina
2014/4/17
We employed real-time pressure recording and high temporal resolution two-dimensional oxygen imaging to characterize the porewater bioadvection related to hydraulic activities of Arenicola marina, a w...
Vitamin B12excretion by cultures of the marine cyanobacteriaCrocosphaera andSynechococcus
Vitamin B12 excretion cultures the marine cyanobacteria Crocos phaera Synechococcus
2014/4/16
Axenic cultures of the N2-fixing marine cyanobacteriumCrocosphaera watsoniiexhibit very high B12excretion rates (up to 40 times higher per cell), compared to the smaller non–N2-fixing strain of marine...
Marine effect of introduced salmonids: Prey consumption by exotic steelhead and anadromous brown trout in the Patagonian Continental Shelf
Marine effect of introduced salmonids Prey consumption exotic steelhead anadromous brown trout the Patagonian Continental Shelf
2014/4/16
On the basis of stable isotope analysis, we estimated the marine diet of the most abundant anadromous salmonid species in Patagonian Atlantic basins. The results were coupled with bioenergetic and pop...
Does predation control adult sex ratios and longevities in marine pelagic copepods?
predation contro adult sex ratios longevities marine pelagic copepods
2014/4/16
We assess the causes of adult sex ratio skew in marine pelagic copepods by examining changes in these ratios between the juveniles and adults, sexual differences in juvenile stage durations, and morta...
Metal accumulation by heterotrophic marine bacterioplankton
heterotrophic marine bacterioplankton Metal accumulation
2014/4/16
Radioisotopes of six metals (54Mn, 55
Fe, 65
Zn, 109
Cd, 137
Cs, and 241Am) were used to assess the accumulation
of these metals by five species of heterotrophic marine bacteria in laboratory cul...

The time for sex A biennial life cycle a marine planktonic diatom
2014/4/16
Whereas it is accepted that the population dynamics of higher organisms isstrongly grounded in life history processes, such as the time taken to mature and reproduce, regulation in the abundance of aq...
