Using the oceanographic ship, the Endeavor; the University of British Columbia undertook a study of Bowie Seamount (53°18', 135°41') during the summer of 1968. Receiving a proton precession magnetometer for the cruise from PNL, a magnetic field survey was included in the study. The magnitude of the observed anomaly was about 850 gammas. The regional was determined by data taken in an airborne magnetic survey done in 1958 by the Dominion Observatory. Corresponding to the topography, the contour plot of the magnetic field showed a strong linear trend from the SW to the NE. In addition, despite fairly symmetrical bathymetry, the observed anomaly is decidedly unsymmetrical, implying a non-uniform intensity of magnetization. This seems to be confirmed by the use of a three dimensional, model - assuming uniform magnetization - developed by Manik Talwani. Using the least squares best fit intensity of magnetization, a large discrepancy was found between the model and the observed anomaly. In light of the fact that the earth's magnetic field has reversed directions many times in its history, the above discrepancy may well be due to the fact that the lava flows of the seamount span at least one time boundary separating a normal and a reversed magnetic period. This is given some credence in that an age determination was made on one sample yielding an age of about 100,000 years, a normal period in the earth's magnetic history. This together with the fact that the magnetic anomaly over most of the seamount is negative yields the above conclusion. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

At the 1996 World Fisheries Congress, Donald A. McCaughran declared seventyfive years of regulatory success for the International Pacific Halibut Commission. The Commission's mandate was to reverse the precipitous decline in halibut stocks that had become apparent in the 1910's, and save this fishery from economic extinction. The biologists and fishermen who sat on the Commission assumed that the appropriate biological target was the one that yielded the maximum sustainable harvest. Using a bioeconomic model of the fishery and regression analysis, I argue the Commission's use of global quotas to achieve its biological goal of maximum sustained yield was most certainly an economic failure. I also argue its policies were very likely a biological failure, as well. While arguably accomplishing its biological goal of the maximum sustainable yield in 1960, dynamic bioeconomic theory indicates their policies probably destabilized the biological fishery. The paper will first sketch the historical background of the industry. Then the regulatory history will be discussed. Then the economic literature will be reviewed as it applies to the Pacific halibut industry. Finally, the historical data will be examined and the proposition that the regulatory management of the halibut fishery was a success will be tested. The period 1928 to 1960 is covered as it provides both reliable data and a continuous period of regulation, at the end of which the biological goal of maximum sustainable yields was apparently achieved. In conclusion, I find that statistically the fishermen were insensitive to the direct effects of the quota and the total quantity of fish available, and instead responded to the quota's indirect effects on the fishermen's costs, which induced the inflow of greater fishing capital than otherwise would have occurred. / Arts, Faculty of / History, Department of / Graduate
