Thin Layers: Observations of Small-Scale Patterns and Processes in the Upper Ocean
Small-Scale Patterns Processes
2015/8/6
Fore decades, marine scientists have been asking questions about the response of planktonic distributions and processes to physical forcing across a range of temporal and spatial scales. The mismatch ...
Acoustical Sensing of Small-Scale Vertical Structures in Zooplankton Assemblages
Small-Scale Vertical Structures Zooplankton Assemblages
2015/8/6
Observation of aquatic animals in their natural environments remains a major challenge in both biological oceanography and limnology. Critical processes in feeding, reproduction, growth, and predation...
Varied observations over Oregon's continental shelf illustrate the beauty and complexity of geophysical flows in coastal waters. Rapid, creative, and sometimes fortuitous sampling from ships and moori...
An integral model of the steady-state dynamics of a shallow, small-scale oceanic front is developed. Such fronts have been observed at the boundaries of river plumes discharging into coastal sea water...
Spectral Characteristics of Small-Scale Fluctuations of Hydrophysical Fields in the Upper Layer of the Ocean
Spectral Characteristics Hydrophysical Fields Small-Scale Fluctuations
2009/3/24
In the P.P. Shirshov Institute of Oceanology of the USSR Academy of Sciences, instrumentation has been developed for the measurement of the fluctuations of the hydrophysical fields in the ocean in the...
Variations in the Intensity of Small-Scale Mixing in the Main Thermocline
Small-Scale Mixing Main Thermocline
2009/3/7
Three cruises to the same site in the central North Pacific (28°N, 155°W) found naked differences in the levels of small-scale turbulent activity as indicated by spectra of temperature profiles. Consi...
Small-Scale Sea Surface Temperature Structure
Small-Scale Sea Surface Temperature Structure
2009/2/16
Observations of sea surface temperature and wave height were made from a large, manned spar buoy (R/P FLIP) 100 km off the coast of Baja California. Surface temperature was measured with a radiation t...
Small-Scale Variations of the Wind-Driven Coastal Sea-Level Response in the West Florida Bight
Small-Scale Variations West Florida Bight] Wind-Driven Coastal Sea-Level
2009/1/21
Records from a number of temporary tide gage stations spaced an average of 20 km apart new Cedar Key, Florida are used to examine the alongshore pressure gradient over length scales much smaller than ...
Entropy Generation In the Ocean by Small-Scale Mixing
Small-Scale Mixing entropy production double diffusion
2009/1/20
An expression that includes salt diffusion was developed and evaluated for the rate of entropy production σ in the ocean. The evaluation was done for mixing events produced by turbulent overturns and ...
Application of the Wigner–Ville Distribution to Temperature Gradient Microstructure:A New Technique to Study Small-Scale Variations
Wigner–Ville Distribution Temperature Gradient Microstructure Small-Scale Variations
2009/1/13
The Wigner–Ville distribution, a new tool in the time–frequency analysis of signals, is applied to temperature gradient microstructure records. In particular, the Wigner–Ville distribution is used to ...
The Structure, Dynamics, and Origin of a Small-Scale Lens of Water in the Western North Atlantic Thermocline
Local Dynamics Experiment Western North Atlantic Thermocline Small-Scale Lens
2009/1/10
A small-scale, isolated, anticyclonically rotating lens of water was observed in the western North Atlantic thermocline during the POLYMODE Local Dynamics Experiment. Using a combination of SOFAR floa...
Observations of Small-Scale Mixing Processes in the Seasonal Thermocline, Part II:Wave Breaking
Small-Scale Mixing Processes Seasonal Thermocline Wave Breaking
2009/1/8
Towed thermistor chain measurements are used to describe a large patch of ocean fine- and microstructure. In contrast to the relatively quiescent salt-fingering conditions of Part I, the 3-km long by ...
Observations of Small-Scale Mixing Processes in the Seasonal Thermocline. Part I:Salt Fingering
Small-Scale Mixing Processes Seasonal Thermocline Salt Fingering
2009/1/8
Towed conductivity microstructure measurements are examined for evidence of salt fingering in the seasonal thermocline of the Sargasso Sea. Patches of limited-amplitude, narrow-bandwidth signals occur...
Normal-Mode Decomposition of Small-Scale Oceanic Motions
Internal Wave Experiment Normal-Mode Decomposition Small-Scale Oceanic Motions
2008/12/23
Small-scale oceanic motions consist of vortical motion and internal waves. In a linear or weakly nonlinear system these two types of motions can be unambiguously separated using normal-mode decomposit...
