Origin of Earth’s oceans: An assessment of the total amount, history and supply of water
origin of water age of oceans water in Earth planet formation snow line
2017/4/10
The presence of water on Earth has played important roles in shaping the solid regions of the planet as well as in the
origin and evolution of life. This paper addresses three fundamental aspects of ...
Supply-Side Ecology and the Response of Zooplankton to Climate-Driven Changes in North Atlantic Ocean Circulation
Response of Zooplankton Supply-Side Ecology
2015/7/29
Recent findings from oceanographic field studies conducted on both sides of the North Atlantic have dramatically altered our view of how zooplankton populations respond to climate-driven changes in oc...
Iron, phosphorus, and nitrogen supply ratios define the biogeography of nitrogen fixation
Iron phosphorus nitrogen fixation
2014/4/2
We present a unified conceptual framework describing the competition between diazotrophs and non–
nitrogen-fixing marine plankton and their interaction with three essential nutrient elements: nitroge...
Downwelling and deep-water bottom currents as food supply mechanisms to the cold-water coralLophelia pertusa(Scleractinia) at the Mingulay Reef complex
Downwelling and deep-water bottom currents food supply mechanisms the cold-water coralLophelia pertusap Mingulay Reef complex
2014/4/18
In 2006 and 2007, multiple deployments of current meters and optical sensors on landers and moorings were made in the first detailed in situ study of the particle supply to the coral community in the ...
Mineralization pathways in lake sediments with different oxygen and organic carbon supply
Mineralization pathways lake sediments different oxygen organic carbon supply
2014/4/17
The intensity and pathways of mineralization of sedimentary organic matter were investigated in eutrophic Lake Zug, Switzerland. In a depth transect (25–180 m) from oxic to anoxic bottom water we reco...
Increased supply of ambient nitrogen has minimal effect on salt marsh bacterial production
Increased supply of ambient nitrogen salt marsh
2014/4/18
We examined the role of chronic low-level nutrient enrichment on the productivity of heterotrophic marsh
bacteria via a marsh fertilization experiment in which we mimicked the conditions of widesprea...
According to Dr. Samuel Johnson, “Promise, large promise, is the
soul of an advertisement.” By this standard, the Reagan economic
program had a lot of soul last year. Embracing the supply-side econo...
Is “Supply-Side” Economics Enough?
Supply-Side current economic problems economic policies
2008/12/17
The Question and the Answer
My answer to the question—Is “supply-side economics” enough?—
is simply that it is both too much and too little. This paper will
elaborate the sense in which “supply-sid...
Tracing abyssal food supply back to upper-ocean processes over a 17-year time series in the northeast Pacific
Tracing abyssal food supply back to upper-ocean processes over a 17-year time series in the northeast Pacific
2014/4/21
Detrital aggregates episodically deposited on the seafloor represent an underestimated food source to deep-sea communities. A 17-yr time-series study was conducted from 1990 to 2006 in the abyssal nor...
Supply of gastropod larvae to hydrothermal vents reflects transport from local larval sources
Supply of gastropod larvae hydrothermal vents
2014/4/21
Variation in larval supply to disjunct marine populations can provide insight into larval transport and delivery
mechanisms, especially when compared with observations of physical transport. Daily va...
Light versus food supply as factors modulating niche partitioning in two pelagic mixotrophic ciliates
Light versus food supply factors modulating niche partitioning two pelagic mixotrophic ciliates
2014/4/21
We studied the vertical distribution of two mixotrophic ciliates,Ophrydium naumanniandStentor araucanusin two contrasting summer seasons (strong vs. mild windy years) to determinewhether differences i...
Physical pathways and utilization of nitrate supply to the giant kelp, Macrocystis pyrifera
Physical pathways utilization of nitrate supply giant kelp, Macrocystis pyrifera
2014/4/18
To determine the relative importance of different sources of nitrate to the annual nitrogen needs of the giant kelpMacrocystis pyrifera,we measured ambient nitrate concentrations at a kelp forest for ...
Effects of turbulence-mediated larval behavior on larval supply and settlement in tidal currents
turbulence-mediated larval larval supply settlement in tidal currents
2014/4/22
Intertidal gastropod larvae retract their vela and sink in strong turbulence, and this behavior potentially increases settlement in turbulent coastal habitats. We incorporated turbulence-induced sinki...
Temperature and nutrient supply interact to control nitrogen fixation in oligotrophic streams: An experimental examination
Temperature and nutrient supply control nitrogen fixation oligotrophic streams
2014/5/5
We performed two experiments to examine how temperature and nutrients interact to control dinitrogen (N2) fixation, chlorophyll a (Chl a) biomass, and community composition of periphyton in subalpine ...
The importance of submarine groundwater discharge to the near shore nutrient supply in the Gulf of Aqaba (Israel)
submarine groundwater discharge near shore nutrient supply the Gulf of Aqaba
2014/5/4
We used two short-lived radium isotopes (223Ra, 224Ra) and a mass balance approach applied to the radium activities to determine the nutrient contribution of saline submarine groundwater discharge to ...
