Large-Scale Physical Forcing of Thin Layer Dynamics

چکیده
My objectives for this study were the following: (1) To work with Drs Holliday and Donaghay to deploy autonomous acoustical and optical instrumentation at eight coastal US sites, (2) to quantify the temporal occurrence and spatial distribution of thin planktonic layers at eight coastal US sites, (3) to assess the hydrography at each of the coastal sites in order to provide a physical context within which we may investigate thin planktonic layers, (4) to expand a database containing information on biological and physical processes related to thin layer dynamics, (5) to select an appropriate site for a future thin layers process study in an open-coast environment.

1 Plankton Patch Feasibility Experiments
Efforts this year focused on testing our model of the effects of episodic increases in current shear on the dynamics and impacts of thin layers of phytoplankton and zooplankton. Thin layers are plankton patches that range in thickness from a few tens of centimeters to a few meters, yet can be sufficiently intense to affect biological rate processes and the performance of current and planned Nav...
متن کاملLayered Organization in the Coastal Ocean: 4-D Assessment of Thin Layer Structure, Dynamics and Impacts
Our long-term goal is to understand (1) the properties of densely concentrated, thin layers of planktonic biota that can occur in coastal ocean environments, (2) the interacting physical, chemical, biological and optical processes responsible for establishment, maintenance and breakdown of layers, (3) the impact of thin layers on the dynamics of plankton populations and the performance of optic...
متن کاملMolecular dynamics studies on the denaturation of polyalanine in the presence of guanidinium chloride at low concentration
Molecular dynamic simulation is a powerful method that monitors all variations in the atomic level in explicit solvent. By this method we can calculate many chemical and biochemical properties of large scale biological systems. In this work all-atom molecular dynamics simulation of polyalanine (PA) was investigated in the presence of 0.224, 0.448, 0.673, 0.897 and 1.122 M of guanidinium chlorid...
متن کاملDimensional transition in rotating turbulence.
In this work we investigate, by means of direct numerical hyperviscous simulations, how rotation affects the bidimensionalization of a turbulent flow. We study a thin layer of fluid, forced by a two-dimensional forcing, within the framework of the "split cascade" in which the injected energy flows both to small scales (generating the direct cascade) and to large scale (to form the inverse casca...
متن کاملEffect of External Forcing on Droplet Dispersion in a Developing Shear Layer
The dynamics and dispersion of nonevaporating droplets in a forced transitional shear layer are studied. The shear layer is formed by two coflowing parallel streams downstream of a splitter plate. The effects of periodic forcing on the dynamics of large-scale vortical structures and on the dispersion characteristics of droplets in a spatially and temporally developing shear layer are investigat...
