• Gayen, Bishakhdatta; Griffiths, Ross W.; Kerr, Ross C. 2015-11-01 Direct numerical simulations are performed to investigate the convection generated when a wall of ice dissolves into seawater under Antarctic ocean conditions. The ambient water temperatures are kept between - 1° C and 6° C and salinities around 35 ppm, where diffusion of salt to the ice-water interface depresses the freezing point and further enhances heat diffusion to the ice. We use three coupled interface equations, along with the Boussinesq approximation and the equation of state for seawater, to solve for interface temperature, salinity and melt rate. Fluxes of both heat and salt to the interface play a significant role in governing the rate of dissolution of ice.

At the presently achievable Grashof numbers turbulence is equally produced from both buoyancy and velocity shear, which indicates the importance of shear production at geophysical scales. • Kopaska-Merkel, D.C.; Mann, S.D. ) 1993-09-01 Upper Smackover strata in Alabama commonly consist of one or more upward-shoaling cycles about 15 to 50 ft (3 to 16 m) in thickness.

Multiple forcing functions (eustasy, regional tilting, salt halokinesis, and autogenic migration of facies) and varying water depths at the start and end of each upward-shoaling cycle generated an array of sedimentary responses. The Brittain No. 1 well, Permit No. 2478, Healing Springs field, Washington County, Alabama, illustrates nucleation of an offshore bar. Bar deposits are capped by anhydritic sabkha deposits, gradationally overlain by subtidal lagoonal strata. Varying rates (and directions ) of halokinesis controlled this succession.

However, it looks like you listened to. 24 – 26 November 2013 Pittsburgh, Pennsylvania American Physical Society.

Locally varying rates of salt movement created as many as five sabkha-capped cycles in this area. The International Paper company 20-5 Mo. 1 well, Permit No.

5242, Blacksher field, Baldwin County, Alabama, contains three upward-shoaling cycles capped by evaporites. Limited aggradational potential of supratidal evaporitic settings permitted subsidence-caused immersion, which eventually permitted reactivation of the carbonate factory and formation of the next cycle.

The Chatom Unit 20-14 No. 1-04 well, Permit No. 7044, Chatom field, Washington County, contains three different cycles. The lower cycle consists of subtidal lime mudstone, capped by a 5-ft (1.5-m) thick soil zone that contains multiple exposure surfaces, tepee structures, and anhydrite pseudomorphs after lenticular gypsum crystals. The soil zone underlies an intraclastic storm deposit followed by a deepening- upward lagoonal succession. A thin ooid grainstone containing exposure surfaces caps the middle cycle.

In the upper cycle, peritidal carbonate strata underlie sabkha deposits. • Pappas, Vasileios; Hatzianastassiou, Nikolaos; Matsoukas, Christos; Koras Carracca, Mario; Kinne, Stefan; Vardavas, Ilias 2015-04-01 been presented and its validity has been tested against satellite-based retrievals. A detailed spectral radiative transfer model (RTM), already used in a number of planetary and regional studies, has been used in the present study to calculate the vertically distributed aerosol direct radiative effects (DREs) and the associated aerosol heating/cooling profiles within the troposphere. Specific emphasis is given to assessment of the crucial issue of the differences between modeling the aerosol DREs using either columnar aerosol optical properties, as usually done, or vertically layered information on those properties, which is the state of the art and ideal practice. To address this problem, the following experiment has been performed: the same RTM has been used twice with the same meteorological conditions but in the first run (set1) columnar values for aerosol optical depth (AOD) have been used while using vertically distributed AOD in the second run (set2).
