Structural profile of the northwestern Caribbean
William P. Dillon, J. G. Vedder, R.J. Graf
1972, Earth and Planetary Science Letters (17) 175-180
A seismic reflection and gravity profile across the continental margin of the Yucatan Peninsula, Yucatan Basin, Cayman Ridge, and Cayman Trough suggests that sediments in the Yucatan Basin consist of a thick succession of beds dominated by turbidites that overlie a thick but irregular sequence of beds, probably dominated by...
Geological framework of the south polar region of Mars
B. C. Murray, L.A. Soderblom, J.A. Cutts, R.P. Sharp, D.J. Milton, R.B. Leighton
1972, Icarus (17) 328-345
The first 4 months of Mariner 9 photography of the south polar region are discussed. Three major geological units have been recognized, separated by erosional unconformities. From oldest to youngest they are: cratered terrain, pitted plains, and laminated terrain. The latter unit is unique in occurrence to the polar region,...
The martian atmosphere: Mariner 9 television experiment progress report

1972, Icarus (17) 373-393
Atmospheric phenomena appearing in the Mariner 9 television pictures are discussed in detail. The surface of the planet was heavily obscured by a global dust storm during the first month in orbit. Brightness data during this period can be fitted by a semi-infinite...

Factors of ecologic succession in oligotrophic fish communities of the Laurentian Great Lakes
Stanford H. Smith
1972, Journal of the Fisheries Research Board of Canada (29) 717-730
Oligotrophic fish communities of the Great Lakes have undergone successive disruptions since the mid-1800s. Major contributing factors have been intensive selective fisheries, extreme modification of the drainage, invasion of marine species, and progressive physical–chemical changes of the lake environments. Lake Ontario was the first to be affected as its basin...
Location and description of spiral-shaped microorganisms in the normal rat cecum
Charles P. Davis, D. Mulcahy, A. Takeuchi, D.C. Savage
1972, Infection and Immunity (6) 184-192
Some indigenous microorganisms have been shown to localize in certain anatomical sites of the digestive tract of mammals. We studied the ceca of normal adult rats by light and electron microscopy to determine whether any specific bacterial population localizes in this area. All rats studied showed...

Population biology of alewives, Alosa pseudoharengus, in Lake Michigan, 1949-70
Edward H. Brown Jr.
1972, Journal of the Fisheries Research Board of Canada (29) 477-500
Alewives were unknown in Lake Michigan before 1949, but became extremely abundant in the 1960s and soon exceeded the carrying capacity of the lake. In 1967 they were decimated by a lakewide mass mortality, and have since been less abundant as "adults" (≥120 mm long), although numerous young were produced in...
The future of salmonid communities in the Laurentian Great Lakes
Stanford H. Smith
1972, Journal of the Fisheries Research Board of Canada (29) 951-957
The effects of human population growth, industrialization, and the introduction of marine fishes have reduced the suitability of each of the Great Lakes for oligotrophic fish communities. The ultimate consequence has been a reduction of fishery productivity that has ranged from extreme in Lake Ontario to moderate in Lake Superior....

Seasonal population characteristics of the opossum shrimp, Mysis relicta, in southeastern Lake Michigan, 1970-71
James B. Reynolds, G.M. DeGraeve
1972, Proceedings of the 15th Conference on Great Lakes Research (15) 117-131
This study of depth distribution, abundance, growth, reproduction and standing crop of the opossum shrimp, Mysis relicta, in southeastern Lake Michigan was based on monthly samples collected from August 1970 through July 1971 (except February and March). Population density was usually low at 10-20 fathoms, moderate at 25-30 fathoms and...
Limnology and fish ecology of sockeye salmon nursery lakes of the world
Wilbur L. Hartman, R.L. Burgner
1972, Journal of the Fisheries Research Board of Canada (29) 699-715
Many important, recently glaciated oligotrophic lakes that lie in coastal regions around the northern rim of the Pacific Ocean produce anadromous populations of sockeye salmon, Oncorhynchus nerka. This paper describes the limnology and fish ecology of two such lakes in British Columbia, five in Alaska, and one in Kamchatka. Then...

Virulence and persistence of rough and smooth forms of Aeromonas salmonicida inoculated into coho salmon (Oncorhynchus kisutch)
Douglas P. Anderson
1972, Journal of the Fisheries Research Board of Canada (29) 204-206
Virulent isolates of Aeromonas salmonicida showed a majority of smooth colonies, while the attenuated isolates displayed mostly rough colonies. A lesion occurred at the site of inoculation when one of the rough forms was inoculated into yearling coho salmon, but few mortalities were recorded even though the rough forms were readily recovered...

Virucidal activity of two Iodophors to salmonid viruses
Donald F. Amend, John P. Pietsch
1972, Journal of the Fisheries Research Board of Canada (29) 61-65
Wescodyne® and Betadine®, organic iodine complexes, were compared in vitro for virucidal activity against infectious hematopoietic necrosis (IHN), infectious pancreatic necrosis (IPN), and viral hemorrhagic septicemia (VHS) viruses. Both iodophors were about equally effective on all three viruses. Each iodophor completely destroyed IHN virus within 30 sec at 12 ppm iodine, and was...
Some physiological consequences of handling stress in the juvenile coho salmon (Oncorhynchus kisutch) and steelhead trout (Salmo gairdneri)
Gary Wedemeyer
1972, Journal of the Fisheries Research Board of Canada (29) 1780-1783
The stress of handling juvenile coho salmon (Oncorhynchus kisutch) and steelhead trout (Salmo gairdneri) in soft water and in water with added salts was evaluated using blood and tissue chemistry fluctuations as indices of metabolic and endocrine function. Changes in plasma glucose, chloride, calcium, and cholesterol levels indicated that significant...
Effect of two Iodophors on bacterial and fungal fish pathogens

In in-vitro tests on nine species of bacteria and two species of fungi, the majority of strains tested did not survive a 5-min exposure to either Betadine or Wescodyne at a concentration of 25 ppm active ingredient....

During 1939-69, 836 cloudburst floods were reported in Utah. The largest number was in 1965, when 88 floods were reported; 63 floods were reported in 1968, and 56 were reported in 1961. The smallest number of floods reported was three in 1944. In 1942, 1948, and 1950, six floods were...
