Isotopic Analysis of Gas from the Cariaco Trench Sediments,ch isotopic equilibrium with the carbon dioxide and interstitial water. The isotopic fractionations between CH. and CO. for .C/.C and between CH. and H.O for D/H were compared with equilibrium fractionations calculated from thermodynamic data. The trench temperature of 17°C differs from thermodynamiType-1-Diabetes 发表于 2025-3-25 09:10:06
The Origin and Distribution of Methane in Marine Sediments,is formed..A methane concentration of 20 mmol/kg approaches the amount required for the formation of gas hydrates under pressure-temperature conditions corresponding to a water column of about 500 meters, with a temperature of 5°C at the sediment-water interface. Depth of stability of the gas hydrat尖牙 发表于 2025-3-25 15:01:12
The Nature and Occurrence of Clathrate Hydrates,stabilities shows that the cages are not completely occupied; thus the clathrate hydrates are non-stoichiometric compounds..Methane hydrate is likely to be a major constituent of the planets Uranus and Neptune. The hydrates of ammonia (2NH. H.O, NH. H.O, and NH.2H.O), which are stoichiometric compoumuscle-fibers 发表于 2025-3-25 17:43:35

Acoustics and Gas in Sediments: Applied Research Laboratories (ARL) Experience,ing sediment coring. The cutting head of the coring barrel is modified to include two transducers and sound speed is recorded as the core barrel penetrates the sediment. The fourth program is an expansion of the sound speed measurement to include both attenuation (by amplitude measurement) and acousFibrin 发表于 2025-3-26 03:06:10
Gas Bubbles and the Acoustically Impenetrable, or Turbid, Character of Some Estuarine Sediments,of sediments had apparently not been tested..Acoustically ‘turbid sediments’ cover large areas of Chesapeake Bay. Along a cross-section parallel to the Bay Bridge near Annapolis, acoustically turbid zones alternate with zones where good sub-bottom records can be obtained. The sediments are quite sim吼叫 发表于 2025-3-26 04:35:49
Book 1974 sponsored four symposia. The first was held in November 1972 at the University of California Con ference Center, Lake Arrowhead. The title of the symposium was "Natural Gases in Marine Sediments and Their Mode of Distribution". Twenty lectures were presented over a three-day period.
