A theoretical study of the transformation of large amplitude internal solitary waves (ISW) of permanent form over a slope–shelf topography is considered using as basis the Reynolds equations. The vertical fluid stratification, amplitudes of the propagating ISWs, and the bottom parameters were taken close to those observed in the Andaman and Sulu Seas. The problem was solved numerically. It was ...

Eastern boundary current systems are among the world's most productive large marine ecosystems. Because upwelling currents transport nutrient-rich but oxygen-depleted water onto shallow seas, large expanses of productive continental shelves can be vulnerable to the risk of extreme low-oxygen events. Here, we report the novel rise of water-column shelf anoxia in the northern California Current s...

STOCK DEFINITION AND GEOGRAPHIC RANGE There are two hematologically and morphologically distinct bottlenose dolphin ecotypes (Duffield et al. 1983; Duffield 1986) which correspond to a shallow water ecotype and a deep water ecotype; both ecotypes have been shown to inhabit waters in the western North Atlantic Ocean (Hersh and Duffield 1990; Mead and Potter 1995; Curry and Smith 1997). Bottlenos...

the sarcheshmeh formation is a shaly sequence of lower cretaceous age (aptian) which is deposited in koppeh-dagh sedimentary basin and conformably overlies and underlies the tirgan and sanghaneh formations respectively in the toos well # 1. lithologically, this formation has a thickness of 177m and consists mainly of marl, shale and shaly limestone. palynological studies resulted in identificat...

In the Southern Ocean, wideranging predators offer the opportunity to quantify how animals respond to differences in the environment because their behavior and population trends are an integrated signal of prevailing conditions within multiple marine habitats. Southern elephant seals in particular, can provide useful insights due to their circumpolar distribution, their long and distant migrati...

The public comment period for the proposed May, 2015 Odor ESL Position Paper, Approaches to Derive Odor-Based Values, and proposed Odor ESL List ended in July 2015. The American Chemistry Council’s Center for Advancing Risk Assessment Science and Policy (ACC), Texas Chemical Council (TCC), Arkema Inc., and OXEA Corporation submitted comments. The TCEQ appreciates the effort put forth by these c...

This article analyzes the emergence of a new stage of global capitalism, called informationalism, and its consequences for English language teaching, focusing on three critical issues. First, globalization will result in the further spread of English as an international language and a shift of authority to nonnative speakers and dialects. This change will call into question basic notions of lan...

Abstract The understanding of how basin margin sediment wedge builds out causes shelf-edge migration with time is approached based on trajectory pattern analysis using a high-resolution mega-merge seismic data from the eastern Niger Delta, Nigeria. study focuses dip transect traversing Greater Ughelli, Central Swamp, Coastal Swamp and Shallow Offshore Depobelts Delta. On regional transects, sed...

1. Introduction The South China Sea (SCS) is a semi-enclosed tropical and subtropical sea located between the Asian land mass (including Taiwan) to the west and north, the Phillipine Islands to the east and Malaysia and Borneo to the south (Figure 1), a total of 3.5×10 6 km 2 surface area. It includes the shallow Gulf of Thailand and connections to the East China Sea (through the Taiwan Strait)...

The present-day continental slope offshore Brunei Darussalam (NW Borneo) displays several networks of submarine channels possessing planform attributes similar to those observed in better studied river systems. We use shallow 3D seismic data to study one tributary network in detail. This network is located directly downslope from the shelf-edge Champion Delta and encompasses an area approximate...
