Collective electronic excitation modes in a superlattice

Creator:

Lee, Yong-Inn

Abstract:

Collective excitation(plasmon) modes of an electron gas in a multilayer system (superlattice) have been studied in great detail in recent years. One important aspect of this Fermion system is that the dispersion relation of the plasma frequency shows transitional behavior between two- and three- dimensional character. Inelastic light scattering experiment...

Using Oregon trawl logbooks to study spatial and temporal characteristics of commercial groundfish species associations

Creator:

Lee, Yong Woo

Abstract:

Species associations of fifteen major commercial groundfish species in the northeastern Pacific ocean and their spatial and temporal characteristics were studied using Oregon bottom trawl logbook data, 1987 to 1993. Screening procedures were used to remove questionable data from the original logbook files, which resulted in the exclusion of information...

Evaluating the Accuracy of Trawl Logbook Estimates of Groundfish Discards

Creator:

Sampson, David B. and Lee, Yong-Woo

Abstract:

The Enhanced Data Collection Project (EDCP), administered by the Oregon Department of Fish and Wildlife, collected data on discard rates for groundfish species and bycatch rates of prohibited species. From late 1995 to early 1999 EDCP observers collected discard data from 235 fishing trips by 25 trawl vessels that voluntarily...
