Natural gas hydrates occur worldwide in polar regions, normally associated with onshore and offshore permafrost, and in sediment of outer continental margins. The total amount of methane in gas hydrates likely doubles the recoverable and non-recoverable fossil fuels. Three aspects of gas hydrates are important: their fossil fuel resource potential, their role as a submarine geohazard, and their effects on global climate change. Since gas hydrates represent huge amounts of methane within 2000 m of the Earth's surface, they are considered to be an unconventional, unproven source of fossil fuel. Because gas hydrates are metastable, changes of pressure and temperature affect their stability. Destabilized gas hydrates beneath the seafloor lead to geologic hazards such as submarine slumps and slides. Destabilized gas hydrates may also affect climate through the release of methane, a "greenhouse" gas, which may enhance global warming.

Wind-induced circulation and sediment transport in semi-enclosed basins: case study for Fethiye bay
Akbaşoğlu, Sinan; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2011)
In this thesis study wind-induced circulation and sediment transport in semi-enclosed basins are carried out for Fethiye Bay. Hydrodynamics of bays are very complex, mainly affected by wind and wave climate, sea bed slope and sediment characteristics. The sea bed profile at the bay changes under winter and summer storms of different speeds and directions. A case study is carried out with the developed methodology. For this reason, Fethiye Bay is selected for the study area. Present structure of Fethiye Bay ...
3D modeling of salt related structures in the friesland platform the Netherlands
Yücel, Kıvanç; Kaymakcı, Nuretdin; Özacar, Atilla Arda; Department of Geological Engineering (2010)
Southern North Sea Basin is one of the mature hydrocarbon basins in NW Europe and is shaped by a number of phases of tectonic deformations during the Phanerozoic. In addition, mobilization and halokinesis of thick Permian Zechstein Salt has enhanced and contributed to the deformation of the region since Triassic, which further complicated the geology of the region. The Friesland Platform, which is a stable platform area located in northern Netherlands, experienced the main deformation phases that Europe has...
Environmental isotopes and noble gases in the deep aquifer system of Kazan Trona Ore Field, Ankara, central Turkey and links to paleoclimate
ARSLAN, Sebnem; Yazıcıgil, Hasan; Stute, Martin; Schlosser, Peter (2013-03-01)
Environmental isotopes and noble gases in groundwater samples from the Kazan Trona Ore Field are studied to establish the temperature change between the Holocene and the late Pleistocene. Noble gas temperatures (NGTs) presented in this study add an important facet to the global paleotemperature map in the region between Europe and North Africa. The groundwater system under investigation consists of three different aquifers named shallow, middle and deep in which delta O-18 and delta H-2 vary from -8.10 part...
Natural gas hydrate potential of the Black Sea
Parlaktuna, Mahmut (2001-04-01)
The Black Sea is among the regions that have been cited in the literature as having conditions suitable for natural gas hydrate reserves. Russian scientists confirmed by seismic studies that there are five regions in the Black Sea which are highly promising for hydrate formation. In this study, conventional petroleum engineering methods are utilized to estimate the possible amount of gas available in one of the Black Sea Basins.
SPATIAL VARIATIONS OF PARTICULATE ORGANIC MATTER (POM) COMPOSITION AND CONCENTRATIONS IN SURFACE WATERS AND SEDIMENTS OF THE MERSIN BAY
Akçay, İsmail; Tuğrul, Süleyman; Department of Oceanography (2015-9-8)
Spatial and temporal variations of hydrophysical properties (temperature, salinity, density), eutrophication-related parameters (nutrients, Chl-a, dissolved oxygen) and particulate organic matter (POM) concentrations and composition (C/N/P) in water column and surface sediments were examined at 33 stations between April 2014 and February 2015 in Mersin Bay located at northeastern (NE) Mediterranean. Regional and seasonal distributions of nutrients in the Mersin Bay are affected by human-induced pressures. H...
