Microbes and the Dissipation of Energy and Respiration: From Cells to Ecosystems
Energy and Respiration From Cells
2015/7/22
In the year 1974, Larry Pomeroy first proposed that microbes were true movers of energy and nutrients in marine food webs (Pomeroy, 1974). This idea was later formalized as the "microbial loop" (Azam ...
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(...
A Study of Tidal Energy Dissipation and Bottom Stress in an Estuary
Tidal Energy Dissipation Bottom Stress Estuary
2009/2/19
A Method for inferring an area-averaged bottom stress and energy dissipation rate in a tidal estuarine channel is presented. The one-dimensional continuity and momentum relations are developed using s...
Dissipation Mechanisms and the Importance of Eddies in Model Ocean Energy Budgets
Dissipation Mechanisms Ocean Energy Budgets
2009/2/16
The importance of mesoscale eddies in the basin energy budgets of closed-basin numerical model oceanic systems that attempt to resolve such motions varies greatly from calculation to calculation. In e...
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...
On the Effect of Dissipation on Seasonal Thermocline Models
Seasonal Thermocline Models dissipation
2009/2/11
This paper considers several parameterizations of dissipation in a Kraus-Turner (1967) seasonal mixed-layer model with no net annual surface buoyancy flux. By studying the behavior of the turbulent ki...
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) ...
Dissipation Within the Surface Mixed Layer
Surface Mixed Layer energy dissipation continental shelf
2009/2/7
Observations of turbulent energy dissipation, measured during a week-long mixed-layer study on the continental shelf off Nova Scotia are presented. This time series of dissipation measurements at a fi...
Turbulent Dissipation Over the Continental Slope Off Vancouver Island
Continental Slope Vancouver Island internal wave energy
2009/2/6
Thirteen profiles of the rate of viscous dissipation of turbulent kinetic energy &epsi¯ were made over the continental slope off Vancouver Island between 12 and 14 May 1980 in conjunction with CT...
On the Balance Between Growth and Dissipation in an Extreme Depth-Limited Wind-Sea in the Southern North Sea
Extreme Depth-Limited Wind-Sea Southern North Sea
2009/2/6
Bouwa has given a discussion of a severe storm in the southern North Sea, on 3 January 1976 near Texel, one of the Friesian islands. This storm was characterized by a remarkable steadiness of wind and...
The Time-Dependent Hydraulic Flow and Dissipation over the Still of Observatory Inlet
Time-Dependent Hydraulic Flow Observatory Inlet
2009/1/12
The time-dependent hydraulic flow over the sill of a tidally energetic fjord, Observatory Inlet, British Columbia, is studied. Acoustic observations of streamlines and velocity were made near the sill...
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...
A Modified Inertial Dissipation Method for Estimating Seabed Stresses at Low Reynolds Numbers, with Application to Wave/Current Boundary Layer Measurements
Inertial Dissipation Method Low Reynolds Numbers Seabed Stresses Wave/Current Boundary Layer Measurements
2009/1/5
The inertial dissipation method for estimating seabed friction velocities from near-bed turbulence spectra requires few measurements; it is relatively insensitive to errors in sensor orientation and m...
Boundary Currents, Free Currents and Dissipation in the Low-Frequency Scattering of Shelf Waves
Boundary Currents Low-Frequency Scattering Free Currents
2009/1/4
The low-frequency scattering of barotropic shelf waves is considered in the limit of small but nonzero dissipation. For a rectilinear shelf it is shown that an intense oscillatory boundary layer forms...

Energy Dissipation Upwelling Western Boundary Current
2008/12/30
Energy dissipation in a western boundary current begins with the conversion of mean potential energy into kinetic energy of “primary” eddies. The rate of this energy conversion is taken to equal the t...
