Seasonal properties of vegetation covering northern boreal and arctic landscapes are considered important as input to numerous climate change studies. In this study, multitemporal phenological characteristics of Alaskan vegetation were studied for the State as a whole, and 19 of 20 ecoregions were studied using seasonally truncated, composited advanced very high resolution radiometer derived normalized difference vegetation index (NDVI) data. Phenological characteristics included four temporal and six greenness metrics derived for each year from 1991 to 1997. Temporal metrics included date of onset of greenness, last day of greenness, date of maximum greenness, and total days of greenness. Greenness metrics consisted of NDVI values recorded during the onset and last day of greenness, maximum greenness, mean greenness for the growing season, and estimated rates of greenup and greendown in the spring and autumn, respectively. Results indicated that over many areas of Alaska there was a trend toward earlier onset of greenness each spring from 1992 to 1997, but the last day of greenness in the autumn was roughly the same. Earlier greenup dates in the spring resulted in a lengthened growing season greenup of up to 20 days in some areas of Alaska from 1992 to 1997. Climate data, however, did not always corroborate these findings. In general, greenness values dropped from 1991 to 1992 and then increased from 1992 to 1997. Values obtained after 1991 may have been affected by atmospheric perturbations owing to the 1991 Mt. Pinatubo eruption and lasting until at least 1997.

This new method streamlines the classical phosphoric acid - calcium carbonate (H3PO4 - CaCO3) reaction method by making use of a Thermoquest-Finnigan GasBench II preparation device and a Delta Plus XL continuous flow isotope ratio mass spectrometer. To obtain reproducible and accurate results, optimal conditions for the H3PO4 - CaCO3 reaction had to be determined. At the acid-carbonate reaction temperature suggested by the equipment manufacturer, the oxygen isotope ratio results were unsatisfactory (standard deviation () greater than 1.5 per mill), probably because of a secondary reaction. When the acid-carbonate reaction temperature was lowered to 26?C and the reaction time was increased to 24 hours, the precision of the carbon and oxygen isotope ratios for duplicate analyses improved to 0.1 and 0.2 per mill, respectively.\r\n\r\nThe method was tested by analyzing calcite from Devils Hole, Nevada, which was formed by precipitation from ground water onto the walls of a sub-aqueous cavern during the last 500,000 years. Isotope-ratio values previously had been obtained by the classical method for Devils Hole core DH-11. The DH-11 core had been recently re-sampled, and isotope-ratio values were obtained using this new method. The results were comparable to those obtained by the classical method. The consistency of the isotopic results is such that an alignment offset could be identified in the re-sampled core material, a cutting error that was then independently confirmed. The reproducibility of the isotopic values is demonstrated by a correlation of approximately 0.96 for both isotopes, after correcting for an alignment offset. This result indicates that the new method is a viable alternative to the classical method. In particular, the new method requires less sample material permitting finer resolution and allows automation of some processes resulting in considerable timesavings.","language":"ENGLISH","doi":"10.3133/ofr01257","usgsCitation":"Revesz, K.M., Landwehr, J., and Keybl, J.E., 2001, Measurement of delta13C and delta18O Isotopic Ratios of CaCO3 by a Thermoquest Finnigan GasBench II Delta Plus XL Continous Flow Isotope Ratio Mass Spectrometer with Application to Devils Hole Core DH-11 Calcite: U.S. Geological Survey Open-File Report 2001-257, iv, 17 p. : ill. ; 28 cm., https://doi.org/10.3133/ofr01257.","productDescription":"iv, 17 p. : ill. ; 28 cm.","costCenters":[],"links":[{"id":176653,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":4220,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/ofr/ofr01-257/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a28e4b07f02db61102d","contributors":{"authors":[{"text":"Revesz, Kinga M. krevesz@usgs.gov","contributorId":506,"corporation":false,"usgs":true,"family":"Revesz","given":"Kinga","email":"krevesz@usgs.gov","middleInitial":"M.","affiliations":[],"preferred":true,"id":241417,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Landwehr, Jurate Maciunas","contributorId":106522,"corporation":false,"usgs":true,"family":"Landwehr","given":"Jurate Maciunas","affiliations":[],"preferred":false,"id":241419,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Keybl, Jaroslav Edward","contributorId":52037,"corporation":false,"usgs":true,"family":"Keybl","given":"Jaroslav","email":"","middleInitial":"Edward","affiliations":[],"preferred":false,"id":241418,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":50380,"text":"ofr0117 - 2001 - Visualization of drifting buoy deployments on St. Clair River near public water intakes - October 3-5, 2000","interactions":[],"lastModifiedDate":"2017-11-10T19:16:38","indexId":"ofr0117","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"2001","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2001-17","title":"Visualization of drifting buoy deployments on St. Clair River near public water intakes - October 3-5, 2000","docAbstract":"St. Clair River is a connecting channel of the Great Lakes between Lake Huron and Lake St. Clair. The river forms part of the international boundary between the United States and Canada in the eastern Lower Peninsula of Michigan and southern Ontario. Drifting buoys were deployed to help investigate flow characteristics near public water intakes in ten reaches of St. Clair River from October 3-5, 2000. In eight deployments, buoys were released at uniform intervals in a transect across the river to better understand flow patterns. In the remaining six deployments, buoys were released in a cluster near the middle of the channel to study turbulent dispersion characteristics. The eight spherical and seven cylindrical buoys used in the study were equipped with drogues and had similar drift characteristics. Each buoy contained a geographical positioning system (GPS) to monitor its movement. Computer animations were developed that integrated these GPS data with data shown on navigational charts. These computer animations, which can be viewed through the Internet, provide a scientific visualization tool to study the deployments.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Lansing, MI","doi":"10.3133/ofr0117","usgsCitation":"Holtschlag, D.J., and Aichele, S., 2001, Visualization of drifting buoy deployments on St. Clair River near public water intakes - October 3-5, 2000: U.S. Geological Survey Open-File Report 2001-17, HTML Document, https://doi.org/10.3133/ofr0117.","productDescription":"HTML Document","costCenters":[{"id":382,"text":"Michigan Water Science Center","active":true,"usgs":true}],"links":[{"id":4181,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr01017","linkFileType":{"id":5,"text":"html"}},{"id":175306,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"Canada, United States","otherGeospatial":"St. Clair River","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ee4b07f02db5fdb3e","contributors":{"authors":[{"text":"Holtschlag, David J. 0000-0001-5185-4928 dholtschlag@usgs.gov","orcid":"https://orcid.org/0000-0001-5185-4928","contributorId":5447,"corporation":false,"usgs":true,"family":"Holtschlag","given":"David","email":"dholtschlag@usgs.gov","middleInitial":"J.","affiliations":[{"id":382,"text":"Michigan Water Science Center","active":true,"usgs":true}],"preferred":true,"id":241315,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Aichele, Stephen S. 0000-0002-3397-7921 saichele@usgs.gov","orcid":"https://orcid.org/0000-0002-3397-7921","contributorId":194508,"corporation":false,"usgs":true,"family":"Aichele","given":"Stephen S.","email":"saichele@usgs.gov","affiliations":[{"id":430,"text":"National Mapping Program","active":false,"usgs":true}],"preferred":false,"id":241316,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":50441,"text":"ofr01362 - 2001 - Geochemical baselines of stream and spring waters from areas underlain by Permian and Pennsylvanian rocks, including evaporites, and potential environmental damage in the Eagle Valley, Colorado","interactions":[],"lastModifiedDate":"2022-01-25T12:30:37.453555","indexId":"ofr01362","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"2001","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2001-362","title":"Geochemical baselines of stream and spring waters from areas underlain by Permian and Pennsylvanian rocks, including evaporites, and potential environmental damage in the Eagle Valley, Colorado","docAbstract":"No abstract available.

The Parkfield mercury district is located in the southern part of the California Coast Range mercury mineral belt and contains three silica-carbonate-type mercury deposits that have had significant mercury production. Mercury was first produced in the district in 1873, but the main period of production occurred from 1915-1922. Total production from the district is about 5,000 flasks of mercury (a flask equals 76 pounds of mercury) with most production coming from the Patriquin mine (1,875 flasks), and somewhat less from the King (1,600 flasks) and Dawson (1,470 flasks) mines. Several other small prospects and mines occur in the district but only minor production has come from them. In 1969, Phelan Sulphur Company carried out mineral exploration at the King mine and announced the discovery of 55,000 tons of mercury ore with an average grade of 5.2 pounds per ton.
\nThe King mine is located on federal land administered by the U.S. Bureau of Land Management. Several other parcels of federal land are present adjacent to other mines and prospects in the Parkfield district. An environmental assessment of mine sites on and adjacent to federal land was carried out to determine the amount of mercury and other trace metals present in mine wastes and in sediments from streams impacted by past mining.

The potentiometric surface was above sea level near the northern boundary and outcrop area of the aquifer in a topographically high area of Anne Arundel County, and was below sea level in the remainder of the study area. The hydraulic gradient was directed southeastward toward an extensive cone of depression around well fields at Lexington Park and Solomons Island. Ground-water levels were more than 80 feet below sea level in a 100-square-mile area surrounding the deepest part of the cone of depression. A cone of depression formed in northern Calvert County due to pumpage at Chesapeake Beach and North Beach. The water level has declined to 43 feet below sea level in this area. The lowest measurement was 164 feet below sea level in a well near the center of the cone of depression at Lexington Park.","language":"ENGLISH","doi":"10.3133/ofr01204","usgsCitation":"Curtin, S.E., Andreasen, D., and Wheeler, J.C., 2001, Potentiometric Surface of the Aquia Aquifer in Southern Maryland, September 1999: U.S. Geological Survey Open-File Report 2001-204, 1 p., https://doi.org/10.3133/ofr01204.","productDescription":"1 p.","costCenters":[],"links":[{"id":4199,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://md.water.usgs.gov/publications/ofr-01-204/","linkFileType":{"id":5,"text":"html"}},{"id":176412,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db683322","contributors":{"authors":[{"text":"Curtin, Stephen E. securtin@usgs.gov","contributorId":3703,"corporation":false,"usgs":true,"family":"Curtin","given":"Stephen","email":"securtin@usgs.gov","middleInitial":"E.","affiliations":[{"id":374,"text":"Maryland Water Science Center","active":true,"usgs":true}],"preferred":true,"id":241390,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Andreasen, David C.","contributorId":59003,"corporation":false,"usgs":true,"family":"Andreasen","given":"David C.","affiliations":[],"preferred":false,"id":241392,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wheeler, Judith C.","contributorId":13620,"corporation":false,"usgs":true,"family":"Wheeler","given":"Judith","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":241391,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":50399,"text":"ofr01172 - 2001 - Energy resources and changing land use, Front Range of Colorado: AAPG-EMD field trip guide, in association with the 2001 AAPG-EMD annual meeting","interactions":[],"lastModifiedDate":"2024-07-31T19:32:24.385418","indexId":"ofr01172","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"2001","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2001-172","title":"Energy resources and changing land use, Front Range of Colorado: AAPG-EMD field trip guide, in association with the 2001 AAPG-EMD annual meeting","docAbstract":"Over the past 30 years, communities in the Northern Front Range of Colorado have experienced tremendous urban and commercial growth rivaling or surpassing that in most other parts of the United States. Much of this growth coincides with areas underlain by critically needed natural resources (such as oil, natural gas, construction aggregate (stone, sand, and gravel), and water), thus presenting serious challenges for city, county, and state planners as well as producers of these natural resources. With projections for as much as a 51 percent increase in population in Colorado over the next 25 years (Colorado Department of Local Affairs, 2001), it is likely that these challenges will increase.
This field trip will blend petroleum and coal geology with discussions of urban development to highlight the interplay between growth in the Front Range and energy resource production. On the trip we will also explore the effects of past production on land use. A total of 6 stops will be made in various locations around the Front Range area.

These two-dimensional models are designed to simulate two ground-water processes: topography-driven flow and advective transport of fluid particles. To simulate topography-driven flow, the user may specify the shape of the water table, which bounds the top of the vertical flow section. To simulate transport of fluid particles, the model domain is a rectangle with overall flow from left to right. In both cases, the flow is under steady state, and the distribution of hydraulic conductivity may be specified by the user. The models compute hydraulic head, ground-water flow paths, and the movement of fluid particles. An interactive visual interface enables the user to easily and quickly explore model behavior, and thereby better understand ground-water flow processes. In this regard, TopoDrive and ParticleFlow are not intended to be comprehensive modeling tools, but are designed for modeling at the exploratory or conceptual level, for visual demonstration, and for educational purposes.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr01286","usgsCitation":"Hsieh, P.A., 2001, TopoDrive and ParticleFlow--Two computer models for simulation and visualization of ground-water flow and transport of fluid particles in two dimensions: U.S. Geological Survey Open-File Report 2001-286, 30 p., https://doi.org/10.3133/ofr01286.","productDescription":"30 p.","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":179579,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":4222,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://water.usgs.gov/nrp/gwsoftware/tdpf/ofr01-286.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a53e4b07f02db62b2f7","contributors":{"authors":[{"text":"Hsieh, Paul A. 0000-0003-4873-4874 pahsieh@usgs.gov","orcid":"https://orcid.org/0000-0003-4873-4874","contributorId":1634,"corporation":false,"usgs":true,"family":"Hsieh","given":"Paul","email":"pahsieh@usgs.gov","middleInitial":"A.","affiliations":[{"id":39113,"text":"WMA - Office of Quality Assurance","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":241434,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":50407,"text":"ofr01208 - 2001 - Potentiometric surface of the upper Patapsco aquifer in southern Maryland, September 1999","interactions":[],"lastModifiedDate":"2012-02-02T00:10:05","indexId":"ofr01208","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"2001","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2001-208","title":"Potentiometric surface of the upper Patapsco aquifer in southern Maryland, September 1999","docAbstract":"This report presents a map showing the potentiometric surface of the Upper Patapsco aquifer in the Patapsco Formation of Cretaceous age in Southern Maryland during September 1999.

The U.S. Geological Survey and the Bureau of Land Management, in cooperation with the U.S. Department of Energy, sampled water from five stock wells to monitor water quality of the Snake River Plain aquifer south of the Idaho National Engineering and Environmental Laboratory. The samples were analyzed for selected radiochemical and chemical constituents.
The concentrations of strontium-90, transuranic elements, and cesium-137 in all samples were less than the reporting level. Concentrations of tritium in four samples and concentrations of gross alpha-and beta-particle radioactivity in all samples were greater than the reporting level. Most of the inorganic-constituent concentrations were greater than the minimum reporting levels. Concentrations of all 63 purgeable organic compounds analyzed for were less than the respective minimum reporting levels.

The project is focused specifically on the Quaternary geology of the river valley and the relationship between the valley's alluvial architecture and the hydrogeology of its wetlands. The Quaternary geology of the river valley has been determined through a field reconnaissance and visual inspection of topographic maps and digital elevation data. Data describing the morphology of the main channel and the physical properties of Lisbon Bottom have been collected. On the basis of these data, a preliminary model of the alluvial architecture of Lisbon Bottom has been developed, but it lacks subsurface verification owing to equipment failures and unseasonable high water. To date, the publications and presentations describing the project include a U.S. Geological Survey Open-File Report (OFR 01-176), two seminars hosted by the University of Missouri - Rolla, and an abstract that was submitted and accepted by the Geological Society of America for its annual fall meeting in November 2001.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr2001368","usgsCitation":"Spooner, J., 2001, The Evolution of the Lower Missouri River: Preliminary Results of NMD Research at Lisbon Bottom: U.S. Geological Survey Open-File Report 2001-368, 13 p., https://doi.org/10.3133/ofr2001368.","productDescription":"13 p.","numberOfPages":"13","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":175849,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2001/0368/coverthb.jpg"},{"id":345475,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0368/ofr01368.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","otherGeospatial":"Lisbon Bottom, Missouri River","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac7e4b07f02db67aff4","contributors":{"authors":[{"text":"Spooner, Jeffrey","contributorId":49010,"corporation":false,"usgs":true,"family":"Spooner","given":"Jeffrey","affiliations":[],"preferred":false,"id":241468,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":50403,"text":"ofr01188B - 2001 - Geology of the Chesapeake and Ohio Canal National Historical Park and Potomac River corridor, Distric of Columbia, Maryland, West Virginia, and Virginia","interactions":[],"lastModifiedDate":"2012-02-02T00:11:11","indexId":"ofr01188B","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"2001","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2001-188","chapter":"B","title":"Geology of the Chesapeake and Ohio Canal National Historical Park and Potomac River corridor, Distric of Columbia, Maryland, West Virginia, and Virginia","language":"ENGLISH","doi":"10.3133/ofr01188B","usgsCitation":"Southworth, C.S., Brezinski, D.K., Orndorff, R.C., Chirico, P., and Lagueux, K.M., 2001, Geology of the Chesapeake and Ohio Canal National Historical Park and Potomac River corridor, Distric of Columbia, Maryland, West Virginia, and Virginia (Version 1.3): U.S. Geological Survey Open-File Report 2001-188, 102 p., https://doi.org/10.3133/ofr01188B.","productDescription":"102 p.","costCenters":[],"links":[{"id":176317,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":4197,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/of01-188b","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad4e4b07f02db6830ef","contributors":{"authors":[{"text":"Southworth, C.
