Carbon in the Bottom Sediments
2004The burial and accumulation of carbon in the bottom sediments represents the final link in its turnover in the upper part of the biosphere. Subsequently to this stage, carbon is transformed within the geological cycling (katagenesis, metamorphism) and tens million of years pass before its reimbursement back to the upper spheres of the earth, ocean, and

Neural Classifier for Bottom Sediments
2003The article presents the application of neural networks for classification of bottom sediments by means of broadband analysis of hydroacoustical signals. The results of detection of five classes of sediments using a multilayer perceptron with back-propagation have been described below.

Telescopic sampler bottom sediments
2015The telescopic sampler of bottom sediments is developed. The technology of sampling off shore with use of the new tool is described. Experience of application of unique installation for oriented core semling of ground deposits on water areas and in transitional zones is stated.

Gas Hydrates in Ocean Bottom Sediments
AAPG Bulletin, 1982Gas hydrates belong to a special category of chemical substances known as inclusion compounds. An inclusion compound is a physical combination of molecules in which one component becomes trapped inside the other. In gas hydrates, gas molecules are physically trapped inside an expanded lattice of water molecules.

Wavelet applications to bottom sediment classification
The Journal of the Acoustical Society of America, 1995Wavelet signal decomposition techniques applied to fathometer echoes were used for seafloor classification. Fathometer echoes were deconvolved with their source signals to yield transfer functions representative of the seafloor. These transfer functions were then expanded onto damped complex exponential wavelet bases.

Bottom sediments of Loch Tummel, Scotland
Sedimentary Geology, 1986Abstract The surficial bottom sediments of Loch Tummel essentially comprise poorly sorted, polymodal, quartzose silts and sandy silts of high water content (17–87%, mean 69.5%) and wchich are rich i organic matter (L.O.I. 0.8–29%, mean 14.5%). Their polymodality is a reflection of derivation mainly from local tills but appreciable quantities of ...

Radium‐content of ocean‐bottom sediments
Eos, Transactions American Geophysical Union, 1932Many determinations of the radium‐content of various rocks from many localities on the continental surfaces of the Earth have been made, but very few such measurements have been made on the materials comprising the ocean‐bottom sediments.The reason is obvious, but when the vast area of these sediments is considered, and especially their high radium ...

Surface waves and bottom sediment response
Marine Geotechnology, 1977Abstract Field measurements of bottom oscillations and wave characteristics have been made in a study of the interaction of fine‐grained sediments and surface waves. A wave staff, pressure sensor, and accelerometer were used in East Bay, Louisiana, an area that has a fine‐grained clay bottom. The accelerometer contained three solid‐state accelerometers
