Seventy million pounds of seafood wastes, mainly from crab, salmon, and shrimp fishing, containing 22.1 million pounds of COD were discharged to Kodiak Harbor, Alaska in 1970. A private firm was engaged to develop a plan to permit development of beneficial uses for the wastes while concurrently reducing the pollutional load on the harbor. The plan included collection and transportation of the waste to a central processing site on Near Island for by-product recovery. Shellfish wastes would be extracted with dilute alkali to yield a high quality protein and a chitin-calcium carbonate residue, the former to be used as pet food aditives or for industrial applications, and the latter to be exported for conversion to chitin and derived products or used in Alaska as a soil liming and fertilizer material. Fish wastes would also be extracted to yield a concentrated protein product similar to fish solubles oil and bone meal.

This text concentrates on specific air pollution problem areas. Chapters are structured to include a descriptive section which introduces the bulk of the information available concerning the specific problem area, followed by an explanatory section which discusses possible solutions. Work in atmospheric pollution will require specially trained personnel who can respond professionally to the requirements of a problem that spans a wide range of academic disciplines. An interdisciplinary approach is used in this book in the hope of creating the kind of cooperative spirit that must be evidenced if any progress is ever going to be made toward finding an overall solution to the air pollution crisis. - Preface.

The study was conducted to appraise the trophic status of the saline Onondaga Lake, Onondaga County, New York, and to estimate the effects of the proposed waste treatment plant. The determined parameters included circulation patterns, distribution of chemical constituents, and the biotic contents of the lake. Mineral-water equilibria showed an uninterrupted and a widely distributed formation of phosphate-bearing minerals. The predominant component of lake sediments is calcium. The salinity of lake water did not preclude occurrence of a wide variety of phytoplankton, zooplankton, and fish. Proposed waste treatments should significantly increase the supply of dissolved oxygen and lower the phosphorus concentration.

Development of a unidirectional-turbulence probe was undertaken to investigate the feasibility of a small-diameter strain-gaged diaphragm-type pressure transducer and a self-adjusting depth compensation air reservoir for use in the follow-on development of a small (1/2-inch diameter) multidirectional-turbulence probe. A unidirectional probe was developed which is capable of monitoring water velocities over a range of 0.5 to 5 ft/sec in turbulence frequencies of 0 to over 100 Hertz and which will automatically operate in water up to 10-feet deep. Sealing inadequacies in both the air reservoir membrane and the pressure diaphragm permit moisture entry into the air volume covering the strain gages. This has given rise to balance drift and circuitry ground problems that have resulted in the placing of limitations on the water exposure and turbulence monitoring times for the unidirectional probe. These problems also suggested that the concepts cannot be immediately incorporated into a multidirectional probe design.
