Deep sea bottom-simulating-reflectors: calibration of the base of the hydrate stability field as used for heat flow estimates *
Ocean Drilling Program and Deep Sea Drilling Project downhole data from three areas, the southwestern Japan Nankai margin, the continental slope off Peru, and the Blake-Bahama Outer Ridge, provide temperature calibrations for bottom simulating reflectors (BSR) that mark the base of a clathrate hydrate stability field. The inferred temperatures at BSRs provide an important reference for the mapp...
متن کاملOrigin of bottom-simulating reflectors: Geophysical evidence from the Cascadia accretionary prism
Vertical seismic profile (VSP) data from two drill sites on the Cascadia margin show low-velocity zones, indicative of free gas, beneath a bottom-simulating reflector (BSR). Offshore Oregon, at Ocean Drilling Program (ODP) Site 892, velocities drop from an average of 1750 m/s above the BSR to less than 1250 m/s below it. Sonic logs confirm that seismic velocity in the sediments adjacent to the ...
متن کاملSimulating offshore sand waves
Sand waves form a prominent regular pattern in the offshore seabeds of sandy shallow seas and pose a threat to a range of offshore activities. A two-dimensional vertical (2DV) flow and morphological simulation model describing the behaviour of these sand waves has been developed. The simulation model contains the 2DV shallow water equations, with a free water surface and a general bed load form...
متن کاملFluid Flow and Heat Transfer of Nanofluids over a Flat Plate with Conjugate Heat Transfer
The falling and settling of solid particles in gases and liquids is a natural phenomenon happens in many industrial processes. This phenomenon has altered pure forced convection to a combination of heat conduction and heat convection in a flow over a plate. In this paper, the coupling of conduction (inside the plate) and forced convection of a non-homogeneous nanofluid flow (over a flat plate) ...
متن کاملSimulating Fluid Flow and Heat Transfer Using Dissipative Particle Dynamics
Dissipative particle dynamics is a relatively new technique for simulating fluid flow at meso scales that is more computationally efficient but at the same time able to reproduce some of the detail of molecular dynamics simulations. This report gives an introduction to the background of the technique, along with examples of applications in the fields of microfluidics, hydrodynamic behaviour at ...
