Five data cruises were taken on board R/V ACANIA to study the effect on the Geomagnetic Electrokinetograph (GEK) of various environmental factors, including wings, tides, and internal waves, over the Monterey Submarine Canyon. An in situ current meter was used successfully on one occasion to obtain data to establish a k-factor for the GEK in the Submarine Canyon, and to directly measure the particle velocities of internal waves. The observed surface currents measured with the GEK all exhibited little or no correlation with winds and tides. The flows were all generally southerly; their averages agreed with previous measurements made with the GEK. This direction of flow was opposite to the generalizations of Scott and possibly agreed with those of Pirie, depending upon the placement of one of his eddies. The k-factor for the GEK could not be determined because currents measured directly in the thermocline were found to be not correlated with the GEK measurements. However, the average current speeds were in reasonable agreement with currents measured at other times in Monterey Bay, leading to the conclusion that k cannot be much greater than the assumed value of 1.0.

Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.

The geomagnetic electrokinetograph (GEK) was used to measure surface currents near the center of Monterey Bay during six separate 24-hour periods from May through July, 1972. An average of 244 current vectors were derived for each cruise. The mean currents from these cruises are all southerly and ranged from 4.1 cm/sec to 20.4 cm/sec. The average of these mean currents is 12.1 cm/sec toward 163T. These values were compared with individual currents derived from dynamic topographies from the same period. Diurnal and semi-diurnal variations of the current were studied after subjecting the data to a Fourier analysis. It was concluded that there must be at least an indirect coupling of the ocean currents with the semi-diurnal tide at the data point. The diurnal component also is important; it may be tidal or inertial, or merely related to the passage of the sun. (Author).
