Subtropical gyres are enormous rotating ocean currents that generate sustained circulations in the Earth’s subtropical regions just to the north and south of the equator. These gyres are slow-moving w...
This paper provides a spatial and temporal multi-scale approach of European submarine canyons. We first present the long-term geologic view of European margins as related to controls on submarine cany...

Section 388 of the Energy Policy Act of 2005 (EPAct) gave the US Department of the Interior (DOI) jurisdiction over activities that "produce or support production, transportation, or transmission of e...
The Role of the Federal Energy Regulatory Commission in Authorizing Hydrokinetic Technology Projects
Fluid dynamics the free flow of renewable energy ocean waves currents tides fluid dynamics
2015/7/7
There is growing interest in hydrokinetic technologies used to harness the free-flowing, renewable energy of the ocean's waves, currents, and tides, as well as inland rivers, without the use of dams. ...
Ocean Renewable Energy's Potential Role in Supplying Future Electrical Energy Needs
Environmental problems the human the earth's resources climate change conventional energy diversity energy atmospheric carbon emissions the ocean
2015/7/7
The world is facing enormous environmental issues as human consumption has begun to stress Earth's resources, and thus, our ability to sustain our existence in the way we are accustomed. In parallel w...
Species-specific encystment patterns in three Baltic cold-water dinoflagellates: The role of multiple cues in resting cyst formation
Species-specific encystment patterns Baltic cold-water dinoflagellates
2014/4/18
The relationships among cellular nutrient status, environmental conditions (temperature and nutrient
availability), and cyst production were studied in batch cultures of three cold-water dinoflagella...
Role of dispersal in shaping communities of ciliates and heterotrophic flagellates within riverine biofilms
Role of dispersal heterotrophic flagellates
2014/4/17
We tested the role of immigration from the plankton on the structure of local surface-associated communities
of ciliates and heterotrophic flagellates (HF) in flow cells fed with fresh riverine water...
Evidence for the role of methane-derived carbon in a free-flowing, lowland river food web
a free-flowing methane-derived carbon
2014/4/17
We measured the d13
C values of dominant primary consumers and their potential food sources in a
groundwater-fed lowland river. The d13
C of most consumers, such as Gammarus and Simulium, reflected...
Role of hydrophobic extracellular polysaccharide of Aulacoseira granulata (Bacillariophyceae) on aggregate formation in a turbulent and hypereutrophic reservoir

10.2 m) coincided with the peak population density of the diatom Aulacoseira granulata...
The role of climate in shaping zooplankton communities of shallow lakes
shaping zooplankton communities lakes
2014/5/13
We analyzed data from 81 shallow European lakes, which were sampled with standardized methods, for combined
effects of climatic, physical, and chemical features of food-web interactions, with a speci...
The Expanding Role of Ocean Color and Optics in the Changing Field of Operational Oceanography
Marine observation oceanography sea ocean optics
2015/7/29
Ocean observatories are changing the way oceanographers go to sea. The rapidly evolving field of ocean optics is producing new technologies and analysis procedures that are contributing to this transi...
Essential fatty acids in the planktonic food web and their ecological role for higher trophic levels
the planktonic food web Essential fatty acids
2014/5/19
We measured concentrations of essential fatty acids (EFAs) in four size categories of planktonic organisms—
seston (10–64 mm), microzooplankton (100–200 mm), mesozooplankton (200–500 mm), and macrozo...
Surface avoidance by freshwater zooplankton: Field evidence on the role of ultraviolet radiation
Surface avoidance freshwater zooplankton
2014/5/14
The avoidance of surface waters by crustacean zooplankton is a common phenomenon both in marine and
freshwaters. The contemporary paradigm interprets such behavior as an antipredator strategy. Howeve...
Atmospheric deposition of inorganic phosphorus in the Levantine Basin, eastern Mediterranean: Spatial and temporal variability and its role in seawater productivity
Levantine Basin eastern Mediterranean
2014/5/21
Total and dissolved inorganic phosphorus (IP) was measured in both rainwater and aerosol samples collected
from two remote coastal areas: on the island of Crete (Greece) and at Erdemli (Turkey). Part...
