Observation, Hypothesis-Testing, and Discovery in Oceanography
Oceanography Hypothesis-Testi
2015/7/29
Discovery lies at the very heart of scientific endeavor. It heralds progress, the march of science in uncovering the mysteries of the world that surrounds us. But how do discoveries come about? "By ob...
The Cold War and a Test of the Hawaiian Hot Spot Hypothesis
Cold War Hawaiian Hot Spot Hypothesis
2015/7/24
Having just retired from teaching at Moss Landing Marine Laboratories, I have been reflecting upon my life, both in teaching and as a researcher at the U.S. Geological Survey (USGS), and without a dou...
Phytoplankton growth in three rivers: The role of meroplankton and the benthic retention hypothesis
Phytoplankton growth three rivers The role of meroplankton the benthic retention hypothesis
2014/4/8
We analyzed long-term (5–8 yr) hourly time series of chlorophyll (Chl) converted from fluorescence measurements in relation to discharge and light in three medium- to large-size rivers, where plankton...
A Test of the Parsons–Veronis Hypothesis on the Separation of the Gulf Stream
Fleet Numerical Oceanography Center Gulf Stream Parsons–Veronis Hypothesis
2008/12/23
The Parsons–Veronis model, based on a two-layer wind-driven ocean, predicts the latitude at which the western boundary current separates from the western boundary. It has been tested on the Gulf Strea...
Vertical distribution of zooplankton in subalpine and alpine lakes: Ultraviolet radiation, fish predation, and the transparency-gradient hypothesis
Vertical distribution of zooplankton subalpine and alpine lakes Ultraviolet radiation fish predation, the transparency-gradient hypothesis
2014/4/21
The transparency-gradient hypothesis argues that ultraviolet radiation (UV) is a primary determinant of the vertical distribution of zooplankton in transparent lakes with fewer fish, while fish predat...
Mesoscale Variability in Denmark Strait: The PV Outflow Hypothesis
Mesoscale Variability Denmark Strait
2008/10/27
The main test of this new hypothesis is by way of numerical experiments carried out with an isopycnal coordinate ocean model configured to have a marginal sea connected to a deep ocean basin by a shal...
An Alternative Hypothesis for the Origin of the “Mediterranean” Salt Lens Observed off the Bahamas in the Fall of 1976
An Alternative Hypothesis Salt Lens Bahamas Fall
2008/7/17
A hypothesis is presented that the original salt lens, or “meddy,” observed off the Bahamas in the fall of 1976 may have been formed, not near the Mediterranean outflow, but instead in the vicinity of...
Vertical distribution of zooplankton in subalpine and alpine lakes: Ultraviolet radiation, fish predation, and the transparency-gradient hypothesis
Vertical distribution zooplankton in subalpine alpine lakes Ultraviolet radiation fish predation transparency-gradient hypothesis
2014/4/18
The transparency-gradient hypothesis argues that ultraviolet radiation (UV) is a primary determinant of the vertical distribution of zooplankton in transparent lakes with fewer fish, while fish predat...

5 April 2007，Deserts on the seafloor: Edward Forbes and his azoic hypothesis for a lifeless deep ocean by Tom Anderson，While dredging in the Ægean Sea during the mid-19th century, Manxman, Edwar...
Sensitivity of herbivorous zooplankton to phosphorus-deficient diets: Testing stoichiometric theory and the growth rate hypothesis
Sensitivity of herbivorous zooplankton phosphorus-deficient diets Testing stoichiometric theory the growth rate hypothesis
2014/4/22
Stoichiometry and growth rate variation are related aspects of the ecology and evolution of consumer-resource interactions. In zooplankton, these concepts have been explored primarily in a few species...
Mixotrophic versus photoautotrophic specialist algae as food for zooplankton: The light : nutrient hypothesis might not hold for mixotrophs
Mixotrophic versus photoautotrophic specialist algae food for zooplankton The light : nutrient hypothesis mixotrophs
2014/5/9
We reared mixotrophic (Ochromonas tuberculata and Cryptomonas sp.) and photoautotrophic specialist algae (Scenedesmus obliquus) at different light : phosphorus supplies and compared their effects as f...
Toxic Alexandrium blooms in the western Gulf of Maine: The plume advection hypothesis revisited
Toxic Alexandrium blooms western Gulf of Maine plume advection hypothesis revisited
2014/5/8
The plume advection hypothesis links blooms of the toxic dinoflagellate Alexandrium fundyense in the western Gulf of Maine (GOM) to a buoyant plume derived from river outflows. This hypothesis was exa...
Experimental paleoecology (resurrection ecology): Chasing Van Valen’s Red Queen hypothesis
Experimental paleoecology Red Queen hypothesis
2014/5/16
Taking an experimental approach to paleoecology, we evaluated the prey portion of Van Valen’s Red Queen
hypothesis by retrieving diapausing eggs from lake sediments for laboratory tests of evolutiona...
Biological stoichiometry of Daphnia growth: An ecophysiological test of the growth rate hypothesis
Biological stoichiometry Daphnia growth ecophysiological test growth rate hypothesis
2014/5/14
The growth rate hypothesis (GRH) proposes that variation in organism C: P and N: P ratios reflects variation in P content associated with altered allocation to P-rich ribosomal RNA under different gro...
