A team of U.S. Geological Survey geologists, a seismologist, and technicians gathered new geologic, seismic, and deformation data in the Commonwealth of the Northern Mariana Islands (CNMI). Nine volcanic islands on the active East Mariana Ridge north of Saipan were examined between April 20 and May 3, 1994. In addition, a new radio-telemetry seismic station was installed on the island of Agrihan (also spelled Agrigan). This report describes our continuing efforts, that began in May 1981, to establish volcano monitors and to assess hazards in the CNMI. Our previous visits, from September 1990 to May 1992, are documented in Moore and others (1991, 1993).
\nRegional seismicity of the Mariana Island region, as recorded by the USGS National Earthquake Information Center (NEIC), included at least 324 events between January 1, 1991, and February 4, 1994. The largest event was a M 8.1 Guam earthquake on August 8, 1993, which caused extensive damage to that island and was felt on Saipan. Intermittent seismic activity continues to occur in the Anatahan-Sarigan, Guguan-Alamagan-Pagan, and PaganAgrihan-Asuncion areas.
\nMount Pagan volcano was actively erupting ash during our 11 days on the island of Pagan. We were able to document seismicity and ground deformation associated with this volcanic activity. None of the other subaerial volcanoes in the chain showed signs of eruptive activity during our visit, but an overflight in a fixed-wing aircraft by geologist Richard Moore and CNMI Lieutenant Governor Jesus Borja detected an apparent submarine eruption between Farallon de Pajaros (also known as Uracas or Uracus) and Maug. The only surveillance of the three uninhabited islands of Farallon de Pajaros, Maug, and Sarigan was by aerial reconnaissance. Geologists studied the other six islands in greater detail by field mapping and aerial surveillance.
\nElectronic distance measurement (EDM) permanent-glass monitor lines were measured on Agrihan, Pagan, and Anatahan. The majority of line-length changes on Agrihan were insignificant (<16 mm). Mount Pagan's south EDM monitor was reestablished, and 1994 results, compared with 1983 measurements, show large changes associated with renewed volcanic activity. Contractions of 59 mm (stations INS to REF) and 157 mm (stations INS to MID) were measured on the south monitor. The southwest Pagan EDM monitor showed a 56 mm contraction for the same period (stations PAGAN 1 to RIDGE 2). Line-length change of this sense and magnitude usually indicates that inflation has occurred in the volcano. Measurements during the 1994 visit to Pagan Island showed no significant changes (for all measurements made during April-May 1994). Anatahan also showed changes as large as -50 mm, accumulated over a time span of approximately two years.
\nTemperatures and pH values of hot spring waters on Agrihan, Pagan, and Anatahan and fumaroles on Agrihan and Anatahan were measured. The temperature data indicated no significant change in the state of these volcanoes since 1992. We collected warm spring water from Lagoonam Sanhalom (Inland Lake) near Mount Pagan. In addition, we started geologic mapping on Asuncion and Guguan, collected charcoal to date three eruptions of Mount Pagan, and collected rocks on Asuncion, Guguan, Pagan, and Alamagan for petrographic and chemical studies.
\nWe conclude that the low and infrequent shallow seismicity, lack of significant deformation, and low fumarole temperatures suggest that no eruption is likely soon on Agrihan and Alamagan. Anatahan's deformation pattern continues to behave in an erratic manner. Because f the lack of seismicity, it seems unlikely that an eruption of Anatahan will occur soon. The persistent volcanic tremor and significant EDM changes on Mount Pagan mean that small explosive eruptions will continue to occur.

The data were collected to assess the effects of hydropower development on water quality. Water quality was determined by a combination of repeated synoptic field measurements and laboratory analyses. Synoptic measurements were made along a longitudinal transect with 18 mid-channel sampling sites; cross-sectional transects of water quality were measured at 5 of these sites. Water-quality measurements also were made at two sites located on the back-channel (Ohio) side of Browns Island. Water temperature, dissolved oxygen concentration, pH, and specific conductance were measured at each longitudinal-transect and back-channel sampling site. Longitudinal-transect and back-channel stations were sampled at three depths (about 3.3 feet below the surface of the water, middle of the water column, and near the bottom of the river). Cross-sectional transects consisted of three or four detailed vertical pro- files of the same characteristics. Water samples were collected from three depths at the mid-channel vertical profile in each cross-sectional transect and were analyzed for concentrations of phyto- plankton photosynthetic pigments chlorophyll a and chlorophyll b. Estimates of the depth of light penetration (Secchi disk transparency) were made at pigment-sampling locations whenever light and river-surface conditions were appropriate. Synoptic sampling usually was completed in 12 hours or less and was repeated seven times between June 25 and November 6, 1992.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nU.S.G.S.

Three sandbars were instrumented with sensors for continual monitoring of stage, pore pressure, ground-water temperature, and tilt to determine the relation between ground-water flow and sandbar deformation. Data were collected from October 1990 to July 1993 at sandbar -6.5R, which had 17 pore- pressure sensors, 1 stage sensor, 19 temperature sensors, and 8 tilt sensors. Data were collected from April 1991 to March 1993 at sandbar 172.3L, which had 15 pore-pressure sensors, 1 stage sensor, 29 temperature sensors, and 10 tilt sensors. Atten- uation of water-level fluctuation from the zone of fluctuating river stage to the back of the sandbars ranged from 70 percent at sandbar -6.5R to 40 percent for sandbars 43.1L and 172.3L. Shallow tilt occurred at sandbar 43.1L from July 7 to August 10, 1991.

Samples of the underlying, dominantly leached, dacite-rich portion of the ash-flow tuff adjacent to the fumarolic conduit and samples of encrusted fallout from the shallow part of the fossil fumarole were interpreted using the isocon method of Grant (1986). The results show that, relative to unaltered l9l2 dacite, chosen as a standard composition for the protolith in this fossil fumarole, mass was conserved during the alteration reactions for most of the system, but mass gains of l4–2D% were determined for three samples in the leached ash-flow tuff Relative to unaltered dacite protolith, significant enrichments occurred in SO3, LOI (~H2O), Cl, F, Zn, Pb, Cu, Sn, Cr, Ni, As, Sb, Au, Br in various parts of the fossil fumarole. Some of these were during the high-temperature part of the alteration, and some were during cooling processes when acid alteration becomes prominent. The REEs indicate some depletion in highly altered samples relative to dacite protolith and differential mobility of Eu2+ relative to trivalent REEs. This is manifested by positive Eu anomalies in REE patterns normalized against REE in the dacite protolith.
Mineral phases introduced in the alteration assemblages include alunite reflecting high SO3, activity, hydrated aluminum hydroxy-fluoride (a ralstonite-like phase) and fluorite reflecting high F activity, smectite, magnetite, hematite, and goethite reflecting oxidation and hydration reactions. Opal and a portion of the α-cristobalite reflect SiO2, mobility; however, the abundance of α-cristobalite is formed from pumice leached during high-temperature vapor-phase processes and devitrification of the altered glass.

The initial objective of the study is to document the environmental conditions during the mid-Pliocene period of warmer-than-modern global climates (the focus of the USGS Pliocene Research, Interpretation, and Synoptic Mapping [PRISM] project). The investigation also seeks to determine how and when these conditions gave way to the late Quaternary pattern of climatic variations (in which short periods of very moist climates have been separated by long periods of arid conditions). This is a collaborative project involving specialists from the USGS, Kansas State University, and the University of California-Davis in paleontology (Thompson, Buchner, Forester, Bradbury), stratigraphy and sedimentology (Oviatt, Kelsey, Bracht), and paleomagnetism and environmental magnetism (Roberts). The data presented herein represent preliminary findings of the analyses of two cores of Pliocene and early Pleistocene sediments from the eastern Great Basin.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr951","usgsCitation":"Thompson, R., Oviatt, C.G., Roberts, A., Buchner, J., Kelsey, R., Bracht, C., Forester, R.M., and Bradbury, J., 1995, Stratigraphy, sedimentology, paleontology, and paleomagnetism of Pliocene-early Pleistocene lacustrine deposits in two cores from western Utah: U.S. Geological Survey Open-File Report 95-1, 94 p. ill., map ;28 cm., https://doi.org/10.3133/ofr951.","productDescription":"94 p. ill., map ;28 cm.","costCenters":[],"links":[{"id":150898,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1995/0001/report-thumb.jpg"},{"id":7853,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1995/of95-001/","linkFileType":{"id":5,"text":"html"}},{"id":46939,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1995/0001/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b16e4b07f02db6a5319","contributors":{"authors":[{"text":"Thompson, R.S.","contributorId":106516,"corporation":false,"usgs":true,"family":"Thompson","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":177571,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Oviatt, Charles G.","contributorId":36580,"corporation":false,"usgs":false,"family":"Oviatt","given":"Charles","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":177568,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Roberts, A.P.","contributorId":28262,"corporation":false,"usgs":true,"family":"Roberts","given":"A.P.","email":"","affiliations":[],"preferred":false,"id":177567,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Buchner, J.","contributorId":11237,"corporation":false,"usgs":true,"family":"Buchner","given":"J.","email":"","affiliations":[],"preferred":false,"id":177564,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kelsey, R.","contributorId":54222,"corporation":false,"usgs":true,"family":"Kelsey","given":"R.","email":"","affiliations":[],"preferred":false,"id":177569,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Bracht, C.J.","contributorId":11635,"corporation":false,"usgs":true,"family":"Bracht","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":177565,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Forester, R.

Lake Fryxell is a permanently ice-covered, closed-basin lake with 13 tributary streams. Continuous streamflow data were collected at eight sites, and periodic streamflow measurements were made at three sites. Continuous water-temperature and specific- conductance data were collected at seven sites, and periodic water-temperature and specific-conductance data were collected at all sites. Streamflow for all streams measured ranged from 0 to 0.651 cubic meter per second. Water temperatures for all streams measured ranged from 0 to 14.3 degrees Celsius. Specific conductance for all streams measured ranged from 11 to 491 microsiemens per centimeter at 25 degrees Celsius. It is probable that stream- flow in the Lake Fryxell Basin during 1990-92 was greater than average. Examination of the 22-year streamflow record in the Onyx River in the Wright Valley revealed that in 1990 streamflow began earlier than for any previous year recorded and that the peak streamflow of record was exceeded. Similar high-flow conditions occurred during the 1991-92 field season. Thus, the data collected on streams draining into Lake Fryxell during 1990-92 are representative of greater than average stream- flow conditions.","language":"ENGLISH","publisher":"U.S. Geological Survey :\r\nUSGS Earth Science Information Center, Open-File Reports Section [distributor],","doi":"10.3133/ofr94545","usgsCitation":"Von Guerard, P., McKnight, D.M., Harnish, R., Gartner, J.W., and Andrews, E., 1995, Streamflow, water-temperature, and specific-conductance data for selected streams draining into Lake Fryxell, lower Taylor Valley, Victoria Land, Antarctica, 1990-92: U.S. Geological Survey Open-File Report 94-545, 65 p. ill., maps ;28 cm., https://doi.org/10.3133/ofr94545.","productDescription":"65 p. ill., maps ;28 cm.","costCenters":[],"links":[{"id":150069,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1994/0545/report-thumb.jpg"},{"id":21644,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1994/0545/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":46944,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1994/0545/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b15e4b07f02db6a4c86","contributors":{"authors":[{"text":"Von Guerard, Paul","contributorId":40620,"corporation":false,"usgs":true,"family":"Von Guerard","given":"Paul","affiliations":[],"preferred":false,"id":177591,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McKnight, Diane M.","contributorId":59773,"corporation":false,"usgs":false,"family":"McKnight","given":"Diane","email":"","middleInitial":"M.","affiliations":[{"id":16833,"text":"INSTAAR, University of Colorado","active":true,"usgs":false}],"preferred":false,"id":177593,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Harnish, R.A.","contributorId":44565,"corporation":false,"usgs":true,"family":"Harnish","given":"R.A.","email":"","affiliations":[],"preferred":false,"id":177592,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gartner, J.

Summitville catalyzed national debates about the environmental effects of modern mining activities, and became the focus of arguments for proposed revisions to the 1872 Mining Law governing mining activities on public lands. In early 1993, the State of Colorado, U.S. Environmental Protection Agency (EPA), U.S. Geological Survey (USGS), U.S. Fish and Wildlife Service (USFWS), Colorado State University, San Luis Valley agencies, downstream water users, private companies, and individuals began a multi-disciplinary research program to provide needed scientific information on Summitville's environmental problems and downstream environmental effects. Detailed results of this multi-agency effort were presented, along with legal and policy issues, at the Summitville Forum in January, 1995, at Colorado State University, Fort Collins, Colorado.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr9523","usgsCitation":"Plumlee, G.S., and Edelmann, P.R., 1995, An update on USGS studies of the Summitville Mine and its downstream environmental effects (Version 1.1): U.S. Geological Survey Open-File Report 95-23, 10 p. ill., map; 28 cm., https://doi.org/10.3133/ofr9523.","productDescription":"10 p. ill., map; 28 cm.","costCenters":[],"links":[{"id":152187,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1995/0023/report-thumb.jpg"},{"id":7867,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1995/ofr-95-0023/","linkFileType":{"id":5,"text":"html"}},{"id":50014,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1995/0023/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"edition":"Version 1.1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad6e4b07f02db6842cc","contributors":{"authors":[{"text":"Plumlee, Geoffrey S. 0000-0002-9607-5626 gplumlee@usgs.gov","orcid":"https://orcid.org/0000-0002-9607-5626","contributorId":960,"corporation":false,"usgs":true,"family":"Plumlee","given":"Geoffrey","email":"gplumlee@usgs.gov","middleInitial":"S.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":182726,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Edelmann, Patrick R.","contributorId":6469,"corporation":false,"usgs":true,"family":"Edelmann","given":"Patrick","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":182727,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ]}
