Download or read book Surface Currents as Determined by Drift Card Releases on the Continental Shelf Off the Northwestern United States written by Sven I. Johnson and published by . This book was released on 1970 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements on surface current drift off Oregon and Washington were made in March 1964 through February 1966 with plastic drift cards dropped from Coast Guard planes at selected points. Results show pronounced surface drift to the north in winter and to the south in spring, each drift associated with a strong wind flow. From April to late in the fall the drift is variable; during this period drift cards were returned showing surface drift opposite to wind flow, indicating that wind direction and intensity are not necessarily indications of surface current flow.

Book excerpt: Prediction equations correlating density of fingerling rainbow trout with growth, yield, and food use efficiency indicated that ammonia nitrogen resulting from high fish densities wes responsible for reductions in all three factors. These predictable density-dependent responses present fish-culturists with alternatives of density selection for evaluation and attainment of specific goals. In examples, fish-culturists, by manipulating density, could achieve rapid growth, produce the maximum weight possible, balance yield with cost, optimize fish quality, or combine two or more of these goals.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this study was to prepare a comprehensive review of the literature on the physical, chemical, and biological effects of dredging and spoil disposal in estuaries and to identify alternative spoil disposal methods. Specific objectives were to identify the most critical problems relating to dredging and spoil disposal and to summarize the progress made to date in solving these problems. Using literature search facilities, bibliographies, and communications with experts throughout the United States, about 520 scientific and technical articles on dredging and spoil disposal were screened. Information extracted from selected articles is included in this review.

Available in PDF, EPUB and Kindle. Book excerpt: Studies conducted during the first 23 years of impoundment of Lake Francis Case indicated that fish abundance in the early 1970's was about half of that in the late 1950's. Of 39 species collected, 12 were abundant in the 1950's and 8 in the 1970's, but only 4 were abundant throughout the impoundment period.
