The purpose of this report is to present daily precipitation (see table A) and continual incremental (5-minute duration) rainfall data through entire storm periods (see table B) at four of the longest first-order National Weather Service station records in Missouri. These basic data can be used in model studies, unit-hydrographic techniques, and other rainfall-intensity studies.

Deforestation and prairie burning led to erosion of the watershed and siltation of valuable spawning grounds. Marsh spawning areas were drained. Lake-to-river spawning migrations of sturgeon, walleye, and other fishes were blocked by mill dams. Accelerated cultural nutrient loading increased total dissolved solids by nearly 50% (1920-70). Phosphate loading reached 469 metric tons per year by the 1950's and continued to increase. The biomass of phytoplankton increased 20-fold between 1919 and 1963. Oxygen demand for decomposition of these algae so degraded oxygen regimes in the western and central basins by the 1950's that the once abundant mayfly nymphs were destroyed and the central basin hypolimnion became anoxic. The sequence of disappearance or severe depletion of fish species was as follows: lake trout, sturgeon, lake herring, lake whitefish, sauger, blue pike, and walleye. Yellow perch are now declining. All resources were intensively exploited at one time or another. Lake trout suffered only this stress, but changes in the watershed significantly stressed sturgeon and lake whitefish. Degradation of the lake spawning grounds, benthos, and oxygen regimes culminated in severe stress by the 1950's on the remnants of the lake herring and lake whitefish, and on the sauger, blue pike, and walleye. Additional mortality may have been imposed on walleye and blue pike fry by predacious smelt that successfully colonized Lake Erie after first appearing in 1932. The cultural stresses, in the probable order of greatest to least net effects on the fish community of Lake Erie, appear to have been: (1) an intense, opportunistic, ineffectively controlled commercial fishery; (2) changes in the watershed, such as erosion and siltation of stream beds and inshore lake areas, and construction of dams in tributaries; (3) nutrient loading, destruction of biota, and reduction of dissolved oxygen; and (4) the competitive and predatory activities of invading species.","language":"English","publisher":"Great Lakes Fishery Commission","publisherLocation":"Ann Arbor, MI","usgsCitation":"Hartman, W.L., 1973, Effects of exploitation, environmental changes, and new species on the fish habitats and resources of Lake Erie: Technical Report 22, 43 p.","productDescription":"43 p.","numberOfPages":"43","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":287946,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada;United States","otherGeospatial":"Lake Erie","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -83.4797,41.397 ], [ -83.4797,42.907 ], [ -78.8539,42.907 ], [ -78.8539,41.397 ], [ -83.4797,41.397 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53ae7696e4b0abf75cf2bfb8","contributors":{"authors":[{"text":"Hartman, Wilbur L.","contributorId":14763,"corporation":false,"usgs":true,"family":"Hartman","given":"Wilbur","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":354675,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70241870,"text":"70241870 - 1973 - Aeromagnetic discovery of a Baltimore Gneiss dome in the Piedmont of northwestern Delaware and southeastern Pennsylvania","interactions":[],"lastModifiedDate":"2023-03-29T15:01:46.470924","indexId":"70241870","displayToPublicDate":"1973-01-01T09:15:38","publicationYear":"1973","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1796,"text":"Geology","active":true,"publicationSubtype":{"id":10}},"title":"Aeromagnetic discovery of a Baltimore Gneiss dome in the Piedmont of northwestern Delaware and southeastern Pennsylvania","docAbstract":"In the central Appalachian Piedmont the “basement complex” is an assemblage of 1,100- to 1,300-m.y.-old gneisses, migmatites, and amphibolites that crops out in “domes” mantled by younger meta-sedimentary rocks of the Glenarm Series.

Chloroform was added on site to one of each pair of samples to stabilize the organic content of the water by preventing biological decomposition. The samples were subsequently stored at 25 deg.C, and pH and specific conductivity were measured at intervals for a period of 13 months at which time nine additional chemical parameters (total dissolved solids, total alkalinity, chloride, sulfate, silica, calcium, magnesium, sodium and potassium) were measured.pH increased and specific conductivity decreased. Average changes occurring in time from the original levels were not influenced by treatment, and first differed significantly (P<0.05, paired t test) at 14 days for pH and 8.5 months for specific conductivity. Total dissolved solids and sulfate were significantly (P<0.01 and <0.05, respectively) larger in treated than untreated samples after 13 months storage while the reverse was true for calcium (P<0.05). Total alkalinity, chloride, silica, and magnesium, however, did not differ significantly (P>0.05). Sodium and potassium levels were too low to provide meaningful comparisons. It was concluded that chloroform may be advantageous in preserving oligothrophic waters with respect to total dissolved solids, sulfate and calcium.","language":"English","publisher":"North Dakota Academy of Science","usgsCitation":"Adomaitis, V.A., Shoesmith, J., and Swanson, G., 1973, Chemical stability of preserved oligotrophic water samples: Proceedings of the North Dakota Academy of Science, v. 26, no. 2, p. 1-5.","productDescription":"5 p.","startPage":"1","endPage":"5","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":281147,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd5104e4b0b290850f3abb","contributors":{"authors":[{"text":"Adomaitis, V.

Holocene shallow-water hypersaline environments that have the potential to produce dolomite without deposition of more soluble evaporite minerals are found in Shark Bay, Australia, and on the Great Bahama Bank. These hypersalinity systems are characterized by near-vertical isosalinity layers of increasing concentration landward from the open ocean and show little or no relationship to bottom topography. I suggest that a similar but larger scale epicontinentalsalinity system covering the Late Cambrian and Early Ordovician carbonate continental shelf produced a broad wedge of subtidally deposited dolomite in the eastern half of the United States from Mexico to Canada. The distribution of limestone and dolomite in this region is closely keyed to the salinity gradient and accounts for the natural progression from a normal marine limestone facies through a transition zone to a highly saline dolomite facies phase. Algal stromatolite mats and domes occupied low-energy niches in both the limestone and dolomite facies, whereas stratiform algal stromatolites were confined to the areas of moderate energy within the dolomite facies.

Within the Park City Group (Permian), the Plymton Formation, overlying the Kaibab Limestone, is divided informally into five parts. The uppermost Plympton has yielded silicified fossils. The faunule studied is characterized by the scaphopod Plagioglypta and by bellerophontacean and neritacean gastropods, suggestive of a middle Permian age. Specimens are worn, and several lines of evidence suggest that this is a high-energy beach deposit associated with a residual high. The interpretation supplements the field evidence of a hiatus between the Plympton and the overlying Gerster Formation. Other occurrences of elements of the faunule in the equivalent Phosphoria rock complex are noted, but only a few were probably deposited in a high-energy beach environment. A new species of Naticopsis that has the color pattern preserved is named and described.

Green River Formation (Eocene) of Colorado and Utah provide a tentative method of identification and a permissive stratigraphic correlation of tuffs. Tuff beds that have been identified and correlated by stratigraphic means were sampled at five localities in Colorado and Utah to determine if microprobe analyses of biotite could be used as a method of correlation. Although most of the original phenocrysts and
glass shards of these pyroclastic beds have undergone extensive postdepositional alteration, biotite seems to have been unaffected. The
iron, magnesium, and titanium contents of the biotite do not uniquely characterize individual tuff beds, but when the proportions of these
elements are compared in a continuous stratigraphic sequence of beds, correlation of individual tuffs or groups of tuffs is possible over areas
exceeding several hundred square miles. The method may be used for detailed correlation of pyroclastic beds where stratigraphic, faunal, and radiometric methods have been unsatisfactory.
A thick sequence of highly deformed flyschlike metasandstone, slate, and argillite crops out in southern Alaska in the Kenai-Chugach Mountains and on Kodiak and the Shumagin Islands to the southwest. These poorly fossiliferous rocks have long been considered Cretaceous in age because of scattered occurrences of fragmentary shells of Inoceramus. Mainly on the basis of new fossil collections, the age of some of these rocks can now be firmly established as Late Cretaceous (Maestrichtian); the critical fossil is Inoceramus kusiroensis Nagao and Matsumoto. Inoceramus kusiroensis also occurs in the much more fossiliferous and only slightly deformed Matanuska Formation that forms a parallel belt north of the Chugach Mountains. On the basis of faunal, lithologic, and bedding characteristics, the Matanuska Formation is the shelf equivalent of the deepwater, trench, or continental-rise deposits of the Kenai-Chugach Mountains and islands to the southwest. \"Inoceramya concentrica\" Ulrich occurs with Inoceramus kusiroensis and is Maestrichtian in age, not Early Jurassic as E. 0. Ulrich suggested
in 1910. The syntypes of I. concentrica are refigured and a lectotype is designated.
Many housing projects in the metropolitan area of Boston are beyond the reach of municipal sewer systems. Waste water disposed of through septic-tank or cesspool systems percolates to ground-water reservoirs and eventually reaches the streams. The dissolved-solids load in the streams receiving septic-tank effluent is increased by an amount that can be predicted from the housing density. In the study area, highway deicing salts are the only materials other than septic-tank discharge that contribute to water-quality degradation. The effect of these salts on the relationship with housing density is eliminated by subtracting the specific conductance due to sodium chloride from the measured specific conductance of a water sample. The difference is called residual conductance and is proportional to the dissolved-solids content minus the concentration of sodium chloride.

The granitic parts of the complex have Rb-Sr ages of about 2.5 b.y. and are classed as of Precambrian W age. The rocks are divided into two major units: (1.) Bell Creek Gneiss consisting mostly of coarse megacrystic granitic rocks and lesser amounts of mafic gneiss and metasedimentary rocks in layers concordant to the foliation of the granitic gneiss, and (2) Compeau Creek Gneiss, previously described to the east, which is mostly medium-grained granitic gneiss and lesser amounts of massive granitic rocks and locally abundant xenoliths of mafic and metasedimentary rocks. Compeau Creek Gneiss intrudes Bell Creek Gneiss throughout the area. Mafic and metasedimentary rocks in the Bell Creek Gneiss are interpreted as remnants of a greenstone belt. The granitic parts of the Bell Creek Gneiss are of problematic origin. Their
composition suggests a magmatic origin, but they do not intrude any rocks with which they are in contact; they form concordant layers in all
observed places. Granitic parts of the Compeau Creek Gneiss are suspected to be highly altered and partly melted sedimentary rocks.
The mafic parts are probably xenoliths of mafic rocks from the Bell Creek Gneiss.
Recently completed fission-track and K-Ar dating of zircon, sphene, apatite, muscovite, biotite, and hornblende indicate that the Clayton Peak stock was intruded 37-41 m.y. ago, the Alta stock about 32-33 m.y. ago, and the Little Cottonwood stock between 24 and 31 m.y. ago. Pb-a ages on zircon, though showing the same sequence, are about twice as great and are inferred to represent a partial
mixing of inherited Precambrian zircons. Acceptance of a middle Tertiary age for the Little Cottonwood stock requires revision of earlier
interpretations that it could be as old as Late Cretaceous. K-Ar dates also indicate that the Keetley Volcanics are 32 to 35 m.y. old, and a
single date of 37.3 m.y. was obtained on the Traverse Volcanics, suggesting that they are more closely related to volcanic activity in the
adjoining Oquirrh Mountains.

The first step in the study of such a mixture is the fractionation of the mixture. The most common approach with humic acids is to attempt to obtain a molecular weight fractionation by gel-permeation chromatography. However, since the preponderance of evidence indicates that the components of humic acid do not fulfill the basic criteria of uniform shape and chemical structure necessary for obtaining a molecular fractionation on gel-permeation media, molecular weight distributions in humic acids cannot be
evaluated by this method. A fractionation dependent upon chemical structure can be obtained by the manipulation of elution conditions on
a gel-permeation column. This procedure provides a beginning in the isolation and identification of discrete components of humic acids.
Roll-type uranium deposits contain both ore-stage pyrite and preore or diagenetic pyrite that was present in the host rock before the deposits began to form. Ore-stage pyrite forms as the result of redistribution and accretion from the preore pyrite. Accretion of the ore-stage pyrite seems to be governed by natural laws that limit its concentration to only a few times the concentration of the preore pyrite. Accumulations of ore-stage pyrite build up along the leading edge of a supergene oxidation zone which spreads through the host rocks, literally pushing the ore deposits ahead of it. The ore-stage pyrite probably progresses much as a wave that first grows to a nearly fixed amplitude and thereafter is steadily maintained as the mature deposit continues to advance.

Time-drawdown data measured at 17 observation wells during a 3.5-day aquifer test define an average apparent specific yield of 0.13. Soil-moisture-content data measured at nine access holes during the aquifer test indicate that complete gravity drainage had not been attained in the cone of depression by the end of the drawdown period. The moisture-content data were therefore extrapolated with time to define an average specific yield in the range 0.13 to 0.15. The results obtained by the two methods arc in close agreement. However, the significantly lower standard deviation of the results from the moisture-content analysis indicates that extrapolation of the apparent values derived by this method may provide a more reliable estimate of the true specific yield than the apparent values derived by the time-drawdown method. Reliable estimates of specific yield in the zone of seasonal water-level fluctuations are also possible from an evaluation of the soil-moisture change in the spring and summer recession period.

Present and previous studies indicate the occurrence of from two to eight complete field reversal cycles during emplacement of the volcanic field about 78 m.y. ago. Among the rocks
studied, only basalt from the Zosell mining district is important as a major aeromagnetic anomaly source.
Phyllite and marble dredged from the lower part of the continental slope between Cuba and the Yucatan Peninsula seem to support the contention that a pre-early Tertiary metamorphic belt extends from the western Greater Antilles into northern Central America. The minimum K-Ar ages derived from the samples suggest that the metamorphic event was pre-Late Cretaceous, and evaluation of the K-Ar data implies that this metamorphic event is not older than Late Jurassic. Greater antiquity, however, is inferred from structural and stratigraphic relations in British Honduras, where the latest regional metamorphic event was post-Early Permian and pre-Middle Jurassic. Rifting and extension related to plate motions along the British Honduras Quintana Roo margin through Mesozoic and earliest Cenozoic time presumably would preclude extensive regional metamorphism, permitting only limited development of schistose rocks there during that interval. The timing of metamorphic events in western Cuba is uncertain, but a pre-Middle Jurassic episode possibly is reflected in the phyllite and marble terranes of Isla de Pinos and Sierra de Trinidad. Local incipient metamorphism of Early and Middle Jurassic strata in the Sierra de los Organos may have resulted from severe tectonism that began in Late Cretaceous time and diminished in the Eocene.

A complete chemical analysis is given for one. In the Snake Creek-Williams Canyon
outcrop area, where the hybrid rocks grade from granodiorite with 63 percent SiO2 to a quartz monzonite with 76 percent SiO2 within a
horizontal distance of about 3 miles, abundance and crystal habit of the apatite change with rock chemistry. The apatite probably is slightly
more than 90 mole percent fluorapatite in the most felsic rocks, slightly less in the most mafic. The range of F->OH substitution in apatite from this outcrop area is much smaller than in the coexisting biotites. Except for manganese, strontium, sodium, and the rare earths, there is very limited substitution for calcium in the crystal structure of these apatites. Apatites from the more mafic rocks tend to contain a lighter,
more basic assemblage of rare earths, in agreement with results obtained for coexisting allanites, monazites, and zircons.
