Antarctic Bottom Waters Freshening at Unexpected Rate
Antarctic Bottom Waters Freshening Unexpected Rate
2017/2/16
In the cold depths along the sea floor, Antarctic Bottom Waters are part of a global circulatory system, supplying oxygen-, carbon- and nutrient-rich waters to the world’s oceans. Over the last decade...
Rapid Rate of Control-Region Evolution in Pacific Butterflyfishes (Chaetodontidae)
Pacific Butterflyfishes Control-Region Evolution
2015/12/17
Sequence differences in the tRNA-proline
(tRNApro) end of the mitochondrial control-region of
three species of Pacific butterflyfishes accumulated 33–
43 times more rapidly than did changes within ...
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)...

Salinity Variations as an Indicator of the Rate of Water Transport Along the East Coast of the Bothnian Sea.
The Rate of Dissipation of Turbulent Energy in the Upper Layer of the Ocean
Turbulent Energy Upper Layer
2009/3/24
Based on empirical data for the upper layer of the ocean, estimates of the rate of turbulent energy dissipation are obtained. The calculations of were made in four ways. The slope of the spectra E1(...
Selecting Record Length and Digitization Rate for Near-Bed Turbulence Measurements
Selecting Record Length Near-Bed Turbulence Measurements Digitization Rate
2009/2/16
Measured values of turbulence parameters (such as mean, variance or covariance of velocity) will depend on the record length and digitization rate chosen for their computation. Six factors which gover...
Estimates of the Local Rate of Vertical Diffusion from Dissipation Measurements
Local Rate Dissipation Measurements Vertical Diffusion
2009/2/16
Scaling of the turbulent energy equation suggests the balance of terms in the ocean is between turbulent production, dissipation and the loss to buoyancy. In this paper two models for the source of oc...
Effect of Sampling Rate and Random Position Error on Analysis of Drifter Data
Sampling Rate Drifter Data Random Position Error
2009/2/13
The central question discussed here is how the rate at which drifter positions are determined and the position errors affect the calculation of velocity, acceleration and velocity gradients such as di...
Observations of Near-Surface Oceanic Velocity Strain-Rate Variability during and after Storm Events
Near-Surface Oceanic Velocity Strain-Rate Variability Storm Events
2009/2/10
During August of 1977, a series of repeated profiles of the upper ocean were made at Ocean Station Papa (145°W, 50°N) with a velocity/temperature microstructure profiler. A strong correlation of wind-...
Determination of the Rate of Dissipation of Turbulent Energy from Simultaneous Temperature and Velocity Shear Microstructure Measurements
Turbulent Energy Simultaneous Temperature Velocity Shear
2009/2/7
Spectra of turbulence have been examined for both temperature gradient and velocity shear. The data for this comparison are 10–15 m segments of vertical microstructure profiles (at depths of 5–100 m) ...
Rate of Change of Heat Storage of the World Ocean
Heat Storage World Ocean global geographical characteristics
2009/1/7
Results or a Fourier analysis of climatological fields of the monthly rate of change of heat storage for the world ocean are presented. The amplitude and Phase of the first harmonic are shown, as well...
Bottom Stress Estimates from Vertical Dissipation Rate Profiles on the Continental Shelf
Bottom Stress Continental Shelf Vertical Dissipation Rate Profiles
2009/1/6
Measurements of the near-bottom distribution of the turbulent dissipation rate on the continental shelf west of Vancouver Island are used to calculate bottom stress. A free-failing vertical profiler w...
Stratified Turbulence near a Critical Dissipation Rate
Stratified Turbulence Critical Dissipation Rate
2008/12/30
Turbulence in the thermocline was investigated using data observed by the submarine Dolphin. Various length scales, the Reynolds and the Froude numbers of the Dolphin data were compared to those value...
Inferring the Subduction Rate and Period over the North Atlantic
Subduction Rate North Atlantic mixed-layer fluid
2008/12/18
The annual rate at which mixed-layer fluid is transferred into the permanent thermocline—that is, the annual subduction rate Sann and the effective subduction period eff—is inferred from climatologica...
