The earliest formed minerals include pyrope-almandine garnet, tschermakitic augite, pargasite, and rutile. Cumulate textures are present in two of the six specimens studied. The earlier fabric has been extensively brecciated and partly replaced by plagioclase, ilmenite, and a fibrous amphibole. The bulk composition and mineralogy of these rocks are similar to those of garnet pyroxenite lenses within ultramafic rocks. Estimated temperature and pressure for the origin of the Sabah garnet pyroxenites is 850±150° C and 19±4 kbar.
AMBIENT water diffuses into the exposed surfaces of obsidian, forming a hydration layer which increases in thickness with time to a maximum depth of 20–40 µm (ref. 1), this layer being the basic foundation of obsidian dating2,3.
Between 1000 and 2000 infrared (eclipse) and radar anomalies have been mapped on the nearside hemisphere of the Moon. A study of 52 of these anomalies indicates that most are related to impact craters and that the nature of the infrared and radar responses is compatible with a previously developed geologic model of crater aging processes. The youngest craters are pronounced thermal and radar anomalies; that is, they have enhanced eclipse temperatures and are strong radar scatterers. With increasing crater age, the associated thermal and radar responses become progressively less noticeable until they assume values for the average lunar surface. The last type of anomaly to disappear is radar enhancement at longer wavelengths. A few craters, however, have infrared and radar behaviors not predicted by the aging model. One previously unknown feature - a field strewn with centimeter-sized rock fragments - has been identified by this technique of comparing maps at the infrared, radar, and visual wavelengths.
WE have previously arrived at an age of 3,550 Myr for granitic1 gneiss in the vicinities of Morton and Montevideo in the Minnesota River valley, south-western Minnesota. We now report new Rb–Sr analyses (Table 1) and an age of 3,800 Myr for the fine grained foliated phase of the Montevideo Gneiss of Lund2. The rocks have undergone a complex history of metamorphism which remains to be deciphered, but the age determinations reveal that the geological mapping and previous interpretations did not provide a proper basis for sampling.
OPHIOLITES consist of a pseudostratiform sequence, of harzburgite, tectonite, ultramafic and mafic cumulates sometimes including gabbro and quartz diorite (plagiogranite) intrusions, dolerite dyke swarms, pillow lava 1, and deep-sea sediments2-4. This assemblage occurs in all Phanerozoic mountain systems and is interpreted as fossil oceanic crust and uppermost mantle5-10. Outstanding problems include differences between the chemical properties of Ophiolites and rocks thought to represent present-day oceanic crust11,12, the lack in some complexes of recognised dyke swarms or cumulates, and the relative thinness of ophiolite mafic rocks compared with standard oceanic crustal sections5,8,13.

This paper describes preliminary results of an investigative program with the purpose of developing low cost time integrating measurement and averaging devices for water temperature and dissolved oxygen.
Measurements were made in an estuarine area of the Chesapeake Bay over two week periods. With chemical thermometers average water temperature for the two week period was found to be equal to average water temperature measured with thermocouples plus or minus 1.0 C. The slow diffusion of oxygen through the semipermiable sides of plastic bottles permitted the use of water filled bottles to obtain averaged oxygen measurements.
Oxygen measurements for two week averaging times using 500 ml polyethylene bottles were found to vary from conventionally measured and averaged dissolved oxygen by about 1.8 mg/l.

Tentative estimates for the other four are: Anaheim Bay 200, Upper Newport 30-35, Los Penasquitos 30, and Tijuana Estuary 150. These estimates, admittedly very rough, indicate a total Light-footed Rail population on only about 500 birds. Recognizing that rails are secretive and hard to inventory, the actual count could be somewhat higher, but I feel it is most unlikely that the number could be more than 750 birds altogether. Reductions in Light-footed Clapper Rail populations can be attributed almost entirely to loss of habitat. An estimated 26,000 acres of saltmarsh once existed between Santa Barbara and the Mexican border. At present there are approximately 8500 acres, much of which has been degraded by pollution, water diversion, and restriction of tidal flow. Of those areas currently occupied by Clapper Rails, few can be considered to have a very secure future. Of the four major areas only Anaheim Bay appears to be relatively safe from future habitat destruction. Tijuana Estuary, Los Penasquitos Lagoon, and Upper Newport Bay are all threatened by commercial developments that could reduce or destroy local rail populations. I have not visited Baja California, but I believe there is still a substantial population of Clapper Rails in the marshes around San Quintin Bay. Taxonomists do not agree on the subspecific identity of these birds, but some feel they are representatives of the Light-footed race. If so, it is fortunate to have a relatively secure (for now) reservoir of these birds, but whether the Light-footed Clapper Rail survives within the United States may well be decided within the next few years.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Birds","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Wilbur, S., 1974, The status of the light-footed clapper rail: American Birds, v. 28, no. 5, p. 868-870.","productDescription":"868-870","startPage":"868","endPage":"870","numberOfPages":"3","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":194134,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b16e4b07f02db6a5349","contributors":{"authors":[{"text":"Wilbur, S.R.","contributorId":53908,"corporation":false,"usgs":true,"family":"Wilbur","given":"S.R.","email":"","affiliations":[],"preferred":false,"id":332897,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":5220889,"text":"5220889 - 1974 - Thirty-eighth breeding bird census. 27.

Goodness-of-fit and likelihood-ratio tests indicated that the standard Jolly-Seber model was inadequate for the data, so we explored different parameterizations of a model in which survival probability for new captures differed from that of previously marked birds. One possible explanation for the lower local survival rate of new captures is that some of the birds were transients that had no chance of being recaptured. Average survival probability over the entire period was 0.62, and the estimated fraction of transients among unmarked birds was 0.27. We found evidence that chickadee survival rates were lower in years immediately following establishment of the Tufted Titmouse (Parus bicolor) as a territorial species (after 1967) than during years immediately preceding this event. We found no evidence that chickadee survival rates were lower in the years immediately following establishment of territorial raptors (after 1984) than during preceding years.

The birds were on dosage for eight days, and on untreated feed for six days immediately thereafter. Group avoidance response was significantly suppressed (P from 0?01 to <0?001) by chlordane, dieldrin, endrin, Ceresan M, and Aroclor 1254. No effect of DDE on the birds' behaviour could be detected. The behaviour of the endrin-treated birds returned to normal after two days on untreated feed. The data indicated partial recovery for birds treated with dieldrin and chlordane, but none for those Ceresan M, or Aroclor 1254. The percentage of controls responding to the silhouette dropped from an average of 84 for the first four days to 70 on the sixth day; then it increased until the end of the test when it was almost 80. This apparently aberrant behaviour of healthy birds is tentatively attributed to a daily decrease in the discrepancy between the moving silhouette and the birds' schema for the silhouette, followed by maturation of the central nervous system, beginning at about the fourteenth day of age. We believe this maturation effected revival of interest and hence a heightened reaction to the stimulus.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Pollution","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/0013-9327(74)90043-3","usgsCitation":"Kreitzer, J., and Heinz, G.H., 1974, The effect of sublethal dosages of five pesticides and a polychlorinated biphenyl on the avoidance response of coturnix quail chicks: Environmental Pollution, v. 6, no. 1, p. 21-29, https://doi.org/10.1016/0013-9327(74)90043-3.","productDescription":"21-29","startPage":"21","endPage":"29","numberOfPages":"9","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":16227,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://dx.doi.org/10.1016/0013-9327(74)90043-3","linkFileType":{"id":5,"text":"html"}},{"id":193989,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db635e21","contributors":{"authors":[{"text":"Kreitzer, J.F.","contributorId":57170,"corporation":false,"usgs":true,"family":"Kreitzer","given":"J.F.","affiliations":[],"preferred":false,"id":333291,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Heinz, G.

Sublethal levels of DDT do cause an increase in the adrenal cortical tissue of bobwhite quail, which may cause increased secretion of corticosteroids, and in turn affect reproduction. A delicate homeostatic balance exists within the avian endocrine system which may be disturbed by feeding sublethal levels of chlorinated hydrocarbon pesticides. This adverse effect on the endocrine system may cause subtle reproductive failures which go unnoticed until the population is greatly reduced.","language":"English","publisher":"Springer","doi":"10.1007/BF01685295","usgsCitation":"Lehman, J., Peterle, T., and Mulls, C., 1974, Effects of DDT on bobwhite quail adrenal gland: Bulletin of Environmental Contamination and Toxicology, v. 11, no. 5, p. 407-414, https://doi.org/10.1007/BF01685295.","productDescription":"8 p.","startPage":"407","endPage":"414","numberOfPages":"8","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":194112,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"11","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4ae4b07f02db6251c4","contributors":{"authors":[{"text":"Lehman, J.W.","contributorId":74467,"corporation":false,"usgs":true,"family":"Lehman","given":"J.W.","email":"","affiliations":[],"preferred":false,"id":333290,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Peterle, T.J.","contributorId":10108,"corporation":false,"usgs":true,"family":"Peterle","given":"T.J.","email":"","affiliations":[],"preferred":false,"id":333288,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mulls, C.M.","contributorId":39477,"corporation":false,"usgs":true,"family":"Mulls","given":"C.M.","email":"","affiliations":[],"preferred":false,"id":333289,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":5221217,"text":"5221217 - 1974 - Chlorinated hydrocarbon and mercury residues in woodcock in the United States, 1970-71","interactions":[],"lastModifiedDate":"2013-03-20T13:11:02","indexId":"5221217","displayToPublicDate":"2010-06-16T12:17:57","publicationYear":"1974","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3038,"text":"Pesticides Monitoring Journal","onlineIssn":" 0031-615","printIssn":" 0031-615","active":true,"publicationSubtype":{"id":10}},"title":"Chlorinated hydrocarbon and mercury residues in woodcock in the United States, 1970-71","docAbstract":"During Late 1970 and early 1971, 229 woodcock (Philohela minor) were collected from 23 Eastern and Midwestern States. Analyses for chlorinated hydrocarbons and mercury in these migratory birds showed generally low levels which are not considered dangerous to human consumers. In this survey, Louisiana woodcock had lower residues of heptachlor epoxide and DDE than those tested in a 1965 survey. PCB levels, however, may have increased. Mirex levels were greatest in Mississipi and Louisiana woodcock. Pooling of birds and averaging of individually analyzed birds did not provide equivalent estimates of equivalent residues; pool values tended to be larger and more variable. Levels of six chlorinated hydrocarbons and mercury were negatively correlated with the latitude of the collection site. However, this relationship seemed weakest for PCB's. Among eight chemical residues, PCB levels were most often correlated with levels of the other seven. Levels of chlorinated hydrocarbons in wings were correlated with levels in breast muscle and in carcass; however, mean levels of certain residues differed significantly among wing, muscle, and carcass even when compared on a lipid basis.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pesticides Monitoring Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Clark, D.R., and McLane, M.A., 1974, Chlorinated hydrocarbon and mercury residues in woodcock in the United States, 1970-71: Pesticides Monitoring Journal, v. 8, no. 1, p. 15-22.","productDescription":"15-22","startPage":"15","endPage":"22","numberOfPages":"8","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":193529,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269756,"type":{"id":11,"text":"Document"},"url":"https://biodiversitylibrary.org/page/26095565"}],"volume":"8","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dde4b07f02db5e2165","contributors":{"authors":[{"text":"Clark, D.

The analyses separated variation into two or three levels for which variances and percentages of the total variation were derived. The results show that differences among measurements of the same egg contribute little to the sample variance whereas differences among eggs within clutches contribute nearly as much as differences among clutches. It is more efficient and less costly to collect entire clutches of eggs in most studies of shell thickness. Using entire clutches, sample sizes needed to detect differences of 10 percent in shell thickness (at given significance levels and power) were estimated to be eight to 11 clutches for the species studied. For differences of five percent, 26 to 38 clutches are required. Guidelines are presented which may assist other workers in evaluating the efficiency of their sampling designs, and in estimating sample sizes for detecting differences in eggshell thickness in wild birds.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wilson Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Klaas, E., Ohlendorf, H.M., and Heath, R., 1974, Avian eggshell thickness: Variability and sampling: The Wilson Bulletin, v. 86, no. 2, p. 156-164.","productDescription":"156-164","startPage":"156","endPage":"164","numberOfPages":"9","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":16223,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://elibrary.unm.edu/sora/Wilson/v086n02/p0156-p0164.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":193988,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"86","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a82e4b07f02db64af3d","contributors":{"authors":[{"text":"Klaas, Erwin E.","contributorId":21487,"corporation":false,"usgs":true,"family":"Klaas","given":"Erwin E.","affiliations":[],"preferred":false,"id":333294,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ohlendorf, H.
