Deep-water subsurface imagingusing OBS interferometry
Seismic interferometry processing is applied to an active seismic survey collected on ocean bottom seismometers (OBS) deployed at 900-m water depth over a carbonate/ hydrates mound in the Gulf of Mexico. Common midpoint processing and stacking of the extracted Green’s function gives the subsurface PP reflectivity, with a horizontal resolution of half the receiver spacing. The obtained seismic s...
متن کاملThe temperature of Europa’s subsurface water ocean
A 100 km deep liquid water ocean probably underlies the icy exterior of Jupiter’s satellite Europa. The long-term persistence of a liquid ocean beneath an ice shell presents a thermal conundrum: Is the temperature of the ocean equal to the freezing point of water at the bottom of the ice shell, or is it equal to the somewhat warmer temperature at which water attains its maximum density? We argu...
متن کاملForests and Water in Northern Thailand
INTRODUCTION Everyone knows that forest is the source of water for all people who live on Thai soil. We do not have any other source of water in Thailand ... [the forest] provides for underground water storage, making the ground moist as a benefit for all people... The result of cutting forest is the destruction of the water source of the Thai people. (Royal Forest Department/Suan Pa Sirikit, 1...
متن کاملMicro scale exchange processes between surface and subsurface water
Data are presented of experiments with turbulent open channel flow over rough surfaces and large relative submergence, which are conducted in two series with different geometric boundary conditions. During the experiments an oscillating fluid motion in the uppermost filter layer is visualised by the injection of a tracer dye. It is shown that this oscillating fluid motion is driven by highly un...
متن کاملModeling of Water Flow and Nitrate Transport to Subsurface Drains
In this study, the water flow and nitrate transport to a subsurface drain, using a simplified and detailed model, are simulated for the specific hydro-geological conditions of Elverdinge and Assenede, Belgium. Previously, the DRAIN MOD-N model proved to be able to simulate nitrate concentrations and drainage well for an in-situ leaching experiment, the “Hooibeekhoeve” in the community of Geel (...
