The models have also demonstrated important consequences of the physics governing drainage, such as (i) the tendency for laterally homogeneous glacier geometry to produce non-arborescent flow-parallel channels in steady state, (ii) the existence of ‘blind’ channels that terminate before reaching the glacier margin and lead to convex, rather Cited by: Geological Sciences Theses and Dissertations Abstracts: - The abstracts are from Undergraduate Senior Honors Theses, Master's Theses, and PhD Dissertations completed at the University of Texas at Austin in the field of Geological Sciences.
Basin models of the Hanifa, Bab, and Shilaif source rocks indicate that the Shilaif is mature only in the Falaha trough at present, and that the Bab Member matured during the Late Eocene, whereas the onset of hydrocarbon expulsion from the Hanifa Formation occurred during the Late Cretaceous (about million years ago).

This book addresses the problem of inferring the state of the ocean circulation, understanding it dynamically, and even forecasting it through a quantitative combination of theory and observation.
It focuses on so-called inverse methods and related methods of statistical by: Agenda for the 4th SBI Pan-Arctic Meeting Sept. Sopot, Poland “Shelf-Basin Exchange at the Margins of the Arctic: IPY and Beyond” Sun./Mon. 24/arrival to Sopot, Poland Monday: Sept.
AOSB SBE/ICARP working group meeting, at IOPAS, dinner. Examples of such projects include the Study of the Northern Alaskan Coastal System (SNACS), the Synthesis of Arctic System Science (SASS), Russian-American Long-term Census in the Arctic (RUSALCA), the Canadian Arctic Shelf Exchange Study (CASES), and the ongoing Joint Western Arctic Climate Study (JWACS).
Introduction  Large continental shelves comprise over 30% of the surface area of the Arctic Ocean and play a key role in establishing property distributions within the arctic basin [Aagaard et al., ].Three main mechanisms are recognized to drive shelf/basin exchange (SBE); (1) brine drainage, (2) river discharge and the associated estuarine circulation, and (3) wind forcing [cf Cited by: Shelf-basin exchange Steady models of Arctic shelf-basin exchange book of Arctic surface waters estimated from Th/ Ra disequilibrium.
Models for the Distribution of Ra and Th In a system with a constant Ra (and U) activity and a constant scavenging rate of Th, the steady state Th/ Ra values should be concordant with Th/ U ratios.

tion of the Western Arctic work to a pan-Arctic perspective. Integrated process and modeling studies of shelf–basin exchange processes and their sensitivity to global change will be an important methodology in this extrapolation.
A physical–biological cou-pled model is being undertaken as part of the SBI study. Materials from Arctic Shelves are Changing the Water's Composition: Scientists say the input of shelf-derived materials to the central Arctic Ocean over the past decade appears to be increasing.
The recent shift in Arctic ice conditions from prevailing multi‐year ice to first‐year ice will presumably intensify fall–winter sea ice freezing and the associated salt flux to the underlying wate Cited by: 4. Goldner DR (b) Steady models of Arctic shelf-basin exchange.

Measurements of Ra/ Ra in surface waters have been used previously in the Arctic Ocean to infer rates of shelf-basin exchange (Rutgers van der Loeff et al., ; Kadko and Muench, The interior shelves of the Arctic Mediterranean are the shelves of the Kara Sea, Laptev Sea, East Siberian Sea and Beaufort Sea.
They comprise approximately 40% of the total arctic shelf area (∼ × 10 6 km 2) and are distinguished from inflow and outflow shelves by their principal forcing their southern (continental) boundary the interior shelves are dominated by the major Cited by: Beaufort shelf break eddies and shelf‐basin exchange of Pacific summer water in the western Arctic Ocean detected by satellite and modeling analyses Eiji Watanabe First Published: 26 August Methane sources and sinks in the Arctic are poorly quantified.

Various aspects of the C cycle of the Arctic have been discussed in individual chapters of the recently completed Arctic Climate Impact Assessment (), and a book has been devoted to the Arctic's marine organic C cycle (Stein and Macdonald ).
However, there has not been a comprehensive scientific review of the status of the contemporary Cited by: Abstract. The Arctic Ocean is an important sink for atmospheric carbon dioxide (CO 2) with a recent estimate suggesting that the region accounts for as much as 15 % of the global uptake of CO western Arctic Ocean, in particular is a strong ocean sink for CO 2, especially in the Chukchi Sea during the open water season when rates of primary production can reach as high as g C m − by: CHAPTER THREE Emerging Questions.
All global climate models forced with increasing greenhouse gases project that the Arctic will continue to warm at a faster rate than that of the rest of the globe, with concomitant losses in the ice and snow (IPCC, ) that form the fabric of the Arctic as we have known it ().In each of the sections that follow, we identify and discuss in detail emerging.
