Geophysical Evaluation of the Inner Structure of a Historical Earth-Filled Dam

open access: yesProceedings, 2018
Small earth dams usually lack the detailed seepage monitoring system that would provide high resolution data on changes in seepage flow. Alternative solution is monitoring of the temperature and electrical resistivity in the body of the dams. Geophysical

Asphalt mounds and associated biota on the Angolan margin [PDF]

open access: yes, 2014
Release of hydrocarbons from sediments is important in increasing habitat heterogeneity on deep ocean margins. Heterogeneity arises from variation in abiotic and biotic conditions, including changes in substratum, geochemistry, fluid flow, biological ...
