Seismic measurements were analyzed to obtain the thickness and seismic velocity of rock in the low-velocity layer, the velocity of rock behind the layer and the amplitude of seismic energy received at the detectors. Electrical-resistivity measurements were analyzed to obtain the thickness and electrical resistivity of the high-resistivity layer and the resistivity of rock behind the layer. The electrical resistivity and the seismic velocity of rock at depth, the thickness of rock in the low-velocity layer, and the relative amplitude of seismic energy were correlated against the following parameters, all of which are important in tunnel construction: height of the tension arch, stable vertical rock load, rock quality, rate of construction and cost per foot, percentage of lagging and blocking, set spacing, and type and amount of steel support required, The correlations were statistically meaningful, having correlation coefficients ranging in absolute value from about 0·7 to nearly 1·0. This finding suggests the possibility of predicting parameters of interest in tunnel construction from geophysical measurements made in feeler holes drilled ahead of a working face. Predictions might be based on correlations established either during the early stages of construction or from geophysical surveys in other tunnels of similar design in similar geologic environments.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0148-9062(68)90020-X","issn":"01489062","usgsCitation":"Scott, J.H., Lee, F.T., Carroll, R.D., and Robinson, C.S., 1968, The relationship of geophysical measurements to engineering and construction parameters in the Straight Creek Tunnel pilot bore, Colorado: International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, v. 5, no. 1, p. 1-30, https://doi.org/10.1016/0148-9062(68)90020-X.","productDescription":"30 p.","startPage":"1","endPage":"30","numberOfPages":"30","costCenters":[],"links":[{"id":218609,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado","otherGeospatial":"Straight Creek area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -106.01806640624999,\n              39.40012200014591\n            ],\n            [\n              -105.32867431640625,\n              39.40012200014591\n            ],\n            [\n              -105.32867431640625,\n              39.76210275375139\n            ],\n            [\n              -106.01806640624999,\n              39.76210275375139\n            ],\n            [\n              -106.01806640624999,\n              39.40012200014591\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"5","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505baf23e4b08c986b324592","contributors":{"authors":[{"text":"Scott, J.

Some changes were caused by enrichment of the environment, but others primarily by an intensive and selective fishery for certain species. Major changes related to the fishery were less frequent before the late 1930's than in recent years and involved few species. Lake sturgeon (Acipenser fulvescens) were overexploited knowingly during the late 1800's because they interfered with fishing for preferred species; sturgeon were greatly reduced in all lakes by the early 1900's. Heavy exploitation accompanied sharp declines of lake herring (Leucichthys artedi) in Lake Erie during the 1920's and lake whitefish (Coregonus clupeaformis) in Lake Huron during the 1930's. A rapid succession of fish species in Lakes Huron, Michigan, and Superior that started about 1940 has been caused by selective predation by the sea lamprey (Petromyzon marinus) on native predatory species, and the resultant shifting emphasis of the fishery and species interaction as various species declined. Lake trout (Salvelinus namaycush) and burbot (Lota lota), the deepwater predators, were depleted first; this favored their prey, the chubs (Leucichthys spp.). The seven species of chubs were influenced differently according to differences in size. Fishing emphasis and predation by sea lampreys were selective for the largest species of chubs as lake trout and burbot declined. A single slow-growing chub, the bloater, was favored and increased, but as the large chubs declined the bloater was exploited by a new trawl fishery. The growth rate and size of the bloater increased, making it more vulnerable to conventional gillnet fishery and lamprey predation. This situation in Lakes Michigan and Huron favored the small alewife (Alosa pseudoharengus) which had recently become established in the upper Great Lakes, and the alewife increased rapidly and dominated the fish stocks of the lakes. The successive collapses of various stocks after periods of stable production may give some indication of their sustainable yield. The sea lamprey is being brought under control in Lakes Superior, Michigan, and Huron; lake trout are being established; and chinook salmon (Oncorhynchus tshawytscha), coho salmon (O. kisutch), kokanee salmon (O. nerka), and the splake, a hybrid of lake trout and brook trout (Salvelinus fontinalis), are being introduced to reestablish a new species balance. Fish stocks are in a state of extreme instability in these lakes. Careful control of stocking programs and fisheries, and coordination of management among the various states of the United States and the province of Canada (Ontario) which manage the fish stocks, will be required to restore and maintain a useful fishery balance.</p>","language":"English","publisher":"NRC Research Press","doi":"10.1139/f68-063","usgsCitation":"Smith, S.H., 1968, Species succession and fishery exploitation in the Great Lakes: Journal of the Fisheries Research Board of Canada, v. 25, no. 4, p. 667-693, https://doi.org/10.1139/f68-063.","productDescription":"27 p.","startPage":"667","endPage":"693","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133049,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a60e4b07f02db635061","contributors":{"authors":[{"text":"Smith, Stanford H.","contributorId":86711,"corporation":false,"usgs":true,"family":"Smith","given":"Stanford","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":308486,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

These larvicides are too costly and difficult to apply, however, in inland lakes, estuaries, and bays.  Populations of sea lampreys in these areas constitute a threat to the refinement of the control.  The gear available to locate, ample, and evaluate larval populations in deep water are inefficient.  Electric shockers, satisfactory for collecting ammocoetes in streams, are limited to shallow water.  The use of mechanical devices such as the Petersen dredge, anchor dredge, and the orange-peel dredge is time consuming, inefficient, and relatively ineffective in providing reliable quantitative evaluation of population size and composition over large areas of bottom.  A device was required to sample adequately many areas in a short period of time, regardless of the depth of water.  Mobility also was essential to permit operation of the unit in the various Great Lakes and in inland waters.  An electrified beam trawl has been developed that most nearly meets these requirements.  It has been used successfully to collect larvae of the sea lamprey, American brook lamprey (<i>Lampetra lamottei</i>), northern brook lamprey (<i>Ichthyomyzon fossor</i>), and silver lamprey (<i>I. unicuspis</i>).

When the third specimen was officially recorded from Milwaukee, Wisconsin, in March 1952, however, a newspaper story carried a somber warning from a knowledgeable yet anonymous official of the Michigan Department of Conservation that the alewife might raise havoc with the native species.  This warning was fully justified by fact in the years to follow.  An upset of the entire fishery ecology of Lake Michigan was already well under way in 1949 when the sea lamprey was consuming the last vestiges of the lake trout (Salvelinus namaycush) and burbot (Lota lota)- the only abundant and widely distributed predators of the lake.

The abundance and distribution varied considerably within the bay; at the time of the survey, most snails were found near the north-central shore. Environmental characteristics were nearly uniform and had no apparent effect on the distribution; concentrations in different areas at different times appeared to result from water movements induced by winds. The time of the study coincided with a period of reproduction; young-of-the-year snails were most abundant in areas where adults were most common. The frequency distributions of shell height and diameter suggested the presence of two age groups of adults in the population. Considerable natural mortality was seen, both at the time of the study and in other seasons. Only three other gastropods were observed in the bay; the most abundant was another viviparid, Campeloma decisum. Other mollusks present were four species of Sphaeriidae and 18 species of Unionidae.

Scales were taken monthly from marked fish for periods up to 21 months. Scales were also examined from fish that died and from preserved specimens of young-of-the-year for each species. Two marks formed on almost all scales each calendar year. The stronger formed during March-April and the weaker in October-November. Both marks had all the usual characteristics of an annulus but the spring mark was considered the annulus and the fall mark an accessory check. The annulus formed during a period of constant temperatures and of little change in growth or increasing growth. The accessory check formed during a period of declining temperatures (1-5 degrees F, or 0.6-2.8 degrees C, per month) and of little change in growth or declining growth. Most fish grew throughout the winter; the only exceptions were one bloater (<i>Coregonus hoyi</i>) and several of the largest lake whitefish (<i>C. clupeaformis</i>). Fish were always given all the food they would eat to eliminate availability of food as a factor of mark formation. The temperature of the water during the winter (50 ±. 0.3 F; 10.0 ±. 0.2 C) did not arrest metabolic activity.

The seasonal depth distribution of eight common species is described, and temperature relations are discussed. Catch records for less common species are mentioned briefly.\r\nAlewives are mostly pelagic during their first 2 years, but many young of the year are on the bottom in the fall, and yearlings occasionally descend to the bottom in substantial numbers in the spring and fall. Adults are mostly on the bottom in the winter and spring, but a significant portion of the population may be at mid-levels in the summer and fall. Bloaters are in midwater during their first 2 years, but usually on the bottom thereafter. Young-of-the-year American smelt are in midwater except in the fall, yearlings are in midwater or on the bottom, and adults are mostly on the bottom.\r\nAlewives, bloaters, smelt, spottail shiners, trout-perch, and yellow perch on the bottom moved into shallower water in the spring and into deeper water in the fall, in response to temperature changes. Slimy sculpins abandoned inshore areas as water warmed in the spring. Fourhorn sculpins showed a slight movement shoreward in the spring, but changed their depth distribution little thereafter to the end of the trawling season.\r\nAlewives showed the greatest seasonal change in distribution. Large concentrations at 40 to perhaps 70 fathoms (73.2-128.0 m.) in mid-March had migrated to water of less than 15 fathoms (27.4 m.) by mid-April. They were in shallow water along shore or in rivers until early summer; then they began a postspawning movement back into deeper water which continued into the fall. Depth ranges in which greatest numbers of other common species occurred, considering all seasons as a whole, were as follows: bloater, 12 to 50 fathoms (21.9-91.5 m.); American smelt, 5 to 17 fathoms (9.1-31.1 m.); spottail shiners, 3 to 15 fathoms (5.5-27.4 m.); trout-perch, 5 to 17 fathoms (9.1-31.1 m.); yellow perch, 3 to 15 fathoms (5.5-27.4 m.); slimy sculpins, 15 to 40 fathoms (27.4-73.2 m.); fourhorn sculpins, 45 to 70 fathoms (82.2-128.0 m.).\r\nWater temperature ranges (A? C.) in which the various species were most abundant in summer were: alewife, 8 to 22; bloater, 6 to 10; smelt, 6 to 14; spottail shiner, 13 to at least 22; trout-perch, 10 to 16; yellow perch, 11 to at least 22; slimy sculpin, 4 to 6; fourhorn sculpin, 4 to 4.5.
