Oceanography of the British Columbia Coast - Canada Special Publication of Fisheries and Aquatic Sciences 56

291 pages including index and 11 pages of colour photographic plates. Abundantly illustrated in black and white. In an easy and conversational style describes the origin, physical characteristics, and nature of the forces that act within and upon the eastern Pacific Ocean. Describes the origin, shape, and structure of the ocean floor as well as the development of coastlines and beaches. Carefully explains the complex movements of water masses, first in general terms and then specifically with regard to the various coastal regions of British Columbia. Describes the seasonal variations in salinity and temperature and, in a remarkably lucid manner, the complex interaction of planetary body forces which result in the variability of tides. Many of his own experiences as well as those of his colleagues are used to illustrate some of the more spectacular effects of water mass motions, such as the tidal rips in the northern Strait of Georgia, internal gravity waves in Knight Inlet, and the unique tidal whirlpools in Gilford Passage. These and many other aspects of coastal oceanography are presented in such a way that the excitement of the author for the nature of his work is transferred to the reader. This book should have wide appeal. Not only is it suitable for scientists and their students, but should become a standard reference to be found in the libraries of commercial vessels as well as in the collections of yachtsmen. Although the author has no pretensions as to its evangelical significance, he has, with this book, made an outstanding contribution to the enjoyment of the coastal waters of British Columbia." - from Foreward by C.J.
