Transferable Rights of Recreational Fishery: An Application to Red Snapper Fishery in the Gulf of Mexico

The Distributional Impacts of Recreational Fees: A Discrete Choice Model with Incomplete Data

We explore the distributional consequences of various fee schemes and other policy programs to reduce overfishing in the gulf of Mexico recreational fishery. The econometric model allows the marginal utility of income to vary across three income groups. We find that flat fees have a strong proportional effect on the participation of shore fishermen, where low-income anglers predominate, and a relatively small impact on the expensive charter fishery. We also find that the welfare consequences of declining catch rates would fall disproportionately on low-income anglers.

Characterization of Thin Gas Hydrate Reservoir in Ulleung Basin with Stepwise Seismic Inversion

Natural gas hydrates (GHs) filling sand layer pores are the most promising GHs that can be produced via conventional mechanisms in deep-sea environments. However, the seismic tracking of such thin GH-bearing sand layers is subject to certain limitations. For example, because most GH-bearing sand layers are thin and sparsely interbedded with mud layers, conventional seismic data with a maximum resolution of ~10 m are of limited use for describing their spatial distribution. The 2010 Ulleung Basin drilling expedition identified a relatively good GH reservoir at the UBGH2-6 site. However, the individual GH-bearing sand layers at this site are thin and cannot therefore be reliably tracked using conventional seismic techniques. This study presents a new thin layer tracking method using stepwise seismic inversion and 3D seismic datasets with two different resolutions. The high-resolution acoustic impedance volume obtained is then used to trace thin layers that cannot be harnessed with conventional methods. Moreover, we estimate the high-resolution regional GH distribution based on GH saturation derived from acoustic impedance at UBGH2-6. The thin GH layers, previously viewed as a single layer because of limited resolution, are further subdivided, traced, and characterized in terms of lateral variation
