15: Acoustical Poperties of Mud Sediments
نویسنده
چکیده
Goals include the development of models and methods that explain observed material and acoustic properties of different physical types of shallow-ocean mud sediments. Other goals are to assess prior data relating to the acoustic properties of mud and to provide guidance in the development and interpretation of experiments. A related goal is to construct models that will guide inversion techniques for inferring properties of mud sediments, for estimating accuracy of results, and for use in applications. These goals are science relevant to resolving long-term Naval problems of transmission loss and array response in shallow water over mud sediments and of acoustic detection, localization, and classification of objects buried in mud.

متن کاملMud volcanism on the Mediterranean Ridge: Initial results of Ocean Drilling Program Leg 160
Drilling during Ocean Drilling Program Leg 160 (April–May, 1995) revealed important new evidence concerning the internal composition, depositional processes, and age of two mud volcanoes within the Mediterranean Ridge accretionary complex. Holes were drilled at ca. 2000 m water depth on the crest areas, across the flanks of the mud volcanoes, and onto adjacent deep-sea sediments. The main depos...
متن کاملEffects of barite on aspects of the ecology of the polychaete Mediomastus ambiseta
Bante (BaSO,), a major component of drilling muds, can change the texture and erosion properties of surface sediments near offshore d r i h g sites. The effects of barite on the ecology of the marine polychaete Mediomastus arnbiseta (Hartman) were examined in laboratory experiments: a migration experiment, 2 feeding experiments and a growth experiment. In the migration experiment, 18 of 19 worm...
متن کاملThe effect of tidal forcing on biogeochemical processes in intertidal salt marsh sediments
BACKGROUND Early diagenetic processes involved in natural organic matter (NOM) oxidation in marine sediments have been for the most part characterized after collecting sediment cores and extracting porewaters. These techniques have proven useful for deep-sea sediments where biogeochemical processes are limited to aerobic respiration, denitrification, and manganese reduction and span over severa...
متن کاملشناسائی کانیهای رسیِ سری مخزنی چلکن در خزر جنوبی و کاربرد آنها در تعیین نوع گل حفاری در منطقه
Siliciclastic sediments of the Cheleken Series (Lower to Middle Pliocene) are exposed along the northern flank of Elburz Mountain Range. The goal of this study is to identify the clay mineral type in these siliciclastic sediments in Mazandaran and Golestan regions, because this can help in the prediction of drilling mud type that can be used. 23 samples have been collected from Neka, south of G...
