Methane bubbles in Lake Kinneret: Quantification and temporal and spatial heterogeneity

The amount of methane bubbles rising from the bottom of Lake Kinneret was quantified by using a dual-beam echo sounder. Both echo-counting (EC) and echo integration (EI) techniques were implemented. Bubbles can confound the identification of fish targets because their acoustic sizes strongly overlap. Analysis of vertical changes in densities in the anoxic hypolimnion (with no fish) indicated th...

geometric modeling of the horizontal tectonic movements in japan, using geodetic observations

japan is a region of active plate tectonics, well known for its japanese trench a geological feature evolving as a result of north pacific (np) oceanic plate pushing and sub-ducting underneath the north american (na) plate. multiple plate tectonics have been continuously recorded in the region since 1979 by the network of gps stations called geonet. the network operating and monitoring more tha...

Hydrodynamic investigation of multiple rising bubbles using lattice Boltzmann method

Hydrodynamics of multiple rising bubbles as a fundamental two-phase phenomenon is studied numerically by lattice Boltzmann method and using Lee two-phase model. Lee model based on Cahn-Hilliard diffuse interface approach uses potential form of intermolecular forces and isotropic finite difference discretization. This approach is able to avoid parasitic currents and leads to a stable procedure t...
