A Field Study of Oceanic Turbulent Horizontal Diffusion.
Richardson's "four-thirds law" of horizontal diffusion was tested using aerial photography as a data gathering technique. Plywood floats and current crosses suspended both near the surface and at nine feet were used as diffusers. The scales investigated ranged from 10 to 525 meters. The …

Surface Circulation and Horizontal Diffusion Processes of the Lower Chesapeake Bay
… is used to study the surface circulation and horizontal diffusion processes of the lower Chesapeake Bay. The study area encompasses some 160 km<sup>2</sup> and includes the area north of Thimble Shoal Channel, southwest of Chesapeake Channel and west of the Chesapeake Bay Bridge and Tunnel. …

Physics of diurnal warm layers : turbulence, internal waves, and lateral mixing
… enhanced TKE dissipation. Vertically-varying horizontal transport across the upper ocean occurs because a diurnal current exists within the DWL, but not in the unstratified remnant mixed layer below. Therefore, when a DWL is present, the water within DWL is horizontally transported a different …

Freshwater Transport on the Continental Shelf of the Southeastern United States
… conservative property for the calculation of the horizontal diffusion coefficient. The cross-shelf, and 10<sup>7</sup> cm<sup>2</sup>s<sup>-1</sup> on the middle shelf locations. Most shelf regions showed dominant advective cross-shelf transport, while in frontal zone between Savannah and …

Investigating the biogeochemistry of the Mozambique Channel thermocline using an optimum multiparameter analysis approach
… ocean. Its formation is linked to vertical and horizontal diffusion, and it constitutes part of the ocean's wind driven circulation, playing a critical role in the lateral advection and vertical supply of nutrients. In the Indian Ocean, the topography, winds, and inter-ocean exchange make the …

How to re-energize R&D organization in large corporations in mature industries : the impact of hot groups
… hot groups often leave the company, causing the diffusion process to cease. Organizational boundaries largely impair the penetration of hot groups' excitement and creativity. The thesis identified two different patterns in the diffusion process of hot groups into the parent organization. In the …

Understanding the source and distribution of marine macro-plastics in coastal environments
… model is forced by currents, windage, and horizontal diffusion. It was refined to include three coastal boundary conditions; sticky coast, resuspending-unclassified coast, and a resuspending-classified coast, in which there is a distinction between rocky, reflective coasts, and retentive …

Studies of lateral dispersion in the ocean
… the interaction between the mesoscale strain and horizontal diffusion on spatial scales less than 10 km. The second and major part examines lateral dispersion over the continental shelf on scales of 100 m to 10 km and over time scales of 1-5 days. PART I: Lateral Dispersion and the North Atlantic …

Policy Diffusion in U.S. Hazard Mitigation Planning: An Intergovernmental Perspective
… resilience policy literature by examining the diffusion of hazard mitigation policy in the U.S. Using the three-paper model, it investigates the adoption of local hazard mitigation plans (LHMPs) from an intergovernmental perspective. The first paper focuses on horizontal diffusion in hazard …

Nearshore sediment dynamics in a mixed sand/mud environment
… and environmental parameters. Near-bed sediment diffusion and entrainment was examined using an array of micro-scale inline pumps. The effect that cohesive bonding of the mixed sand/mud seabed has on retarding the entrainment rate was examined by considering both the textural and geomechanical …
