High-resolution ⁴⁰Ar/³⁹Ar dating of the oldest oceanic basement basalts in the western Pacific basin

Creator:: Koppers, Anthony A. P., Staudigel, Hubert, and Duncan, Robert A.
Abstract:: We report new ⁴⁰Ar/³⁹Ar ages for the oldest Pacific oceanic floor at Ocean Drilling Program Site 801C in the Pigafetta basin and Site 1149D close to the Izu-Bonin subduction zone in the Nadezhda basin. These ages were determined by applying high-resolution incremental heating experiments (including 15–30 heating steps) to better...

Indicators for Monitoring Biological Integrity of Inland, Freshwater Wetlands : A Survey of North American Technical Literature (1990-2000)

Creator:: Adamus, Paul R.
Abstract:: Potentially relevant literature for the years 1990-1999 was identified by (a) conducting keyword searches of computerized bibliographic databases, especially CAB Abstracts and Aquatic Sciences and Fisheries Abstracts, (b) reading through the tables of contents of a few especially relevant journals, (c) searching the internet for pertinent bibliographies, and (d) to...

Air-sea interaction over ocean fronts and eddies

Creator:: Small, R. J., de Szoeke, Simon P., Xie, S. P., O'Neill, L., Seo, H., Song, Q., Cornillon, P., Spall, M., and Minobe, S.
Abstract:: Air-sea interaction at ocean fronts and eddies exhibits positive correlation between sea surface temperature (SST), wind speed, and heat fluxes out of the ocean, indicating that the ocean is forcing the atmosphere. This contrasts with larger scale climate modes where the negative correlations suggest that the atmosphere is driving the...

Wetlands of Island County, Washington : Profile of Characteristics, Functions, and Health

Creator:: Adamus, Paul R.
Abstract:: This document partially addresses the Wetlands component of Island County’s Critical Areas Ordinance (CAO). It presents the results of a year-long collaborative project to compile, analyze, and summarize existing data pertinent to Island County wetlands. Similar in concept to the “report card” issued periodically for Puget Sound, this compilation attempts...

Protection, Restoration, and Management of Terrestrial Habitats and Species of the Willamette Sub-Basin

Creator:: Adamus, Paul R.
Abstract:: This report and especially the accompanying Detail Files and MapFiles provide relatively detailed information on status, trends, distribution, limiting factors, and conservation needs of all of the Willamette’s wildlife species, listed plants, and vulnerable habitats. Data on habitat suitability for each species is provided by watershed (170 HUC6s), elevation (6...

The Center for Independent Experts: The National External Peer Review Program of NOAA's National Marine Fisheries Service

Creator:: Brown, Stephen K., Shivlani, Manoj, Die, David, Sampson, David B., and Ting, Tina A.
Abstract:: Requirements are growing for peer review of the science used for governmental management decisions. This is particularly true for fisheries science, where management decisions are often controversial. The National Oceanic and Atmospheric Administration's National Marine Fisheries Service instituted the Center for Independent Experts (CIE) in 1998 as a national peer-review...

Semantic Mediation as a Gateway to Interoperability, with a Case Study of the International Coastal Atlas Network (ICAN)

Creator:: Lassoued, Yassine, Wright, Dawn, Bermudez, Luiz, Nyerges, Tim, Haddad, Tanya, and Dwyer, Ned
Abstract:: Basic research on semantic interoperability is just beginning to address support for spatial data and information. This is clearly important for data portals containing geographic information system (GIS) layers, as well as supplemental information, often with cartographic and decision support tools. Agreements on content/semantic interoperability of these resources can help...

Multiple mantle plume components involved in the petrogenesis of subduction-related lavas from the northern termination of the Tonga Arc and northern Lau Basin: Evidence from the geochemistry of arc and backarc submarine volcanics

Creator:: Falloon, Trevor J., Danyushevsky, Leonid V., Crawford, Tony J., Maas, Roland, Woodhead, Jon D., Eggins, Stephen M., Bloomer, Sherman H., Wright, Dawn J., Zlobin, Sergei K., and Stacey, Andrew R.
Abstract:: New seafloor mapping and sampling demonstrates that the eruption of the high-Ca boninites is clearly associated with rifting of the northern Tonga ridge and the northern Lau Basin at the northern termination of the Tonga Trench. There is very strong evidence for OIB plume related mantle sources involved in the...

Climate change in India inferred from geothermal observations

Creator:: Roy, Sukanta, Harris, Robert N., Rao, R. U. M., and Chapman, David S.
Abstract:: Temporal variations in surface ground temperature impart a signal to the subsurface thermal regime that is captured in borehole temperature-depth profiles. Seventy temperature-depth profiles in India, located between 12° and 28°N, are analyzed to infer past changes in ground temperature. These profiles exhibit predominantly positive anomalous temperatures relative to the...

Christmas tree nutrient management guide : western Oregon and Washington [2009]

Creator:: Hart, John M. (John Mervyn), 1947-, Landgren, Chal G., Fletcher, Richard A., Bondi, Michael C., Whithrow-Robinson, Bradford A., Chastagner, Gary A., and Oregon State University. Extension Service
Abstract:: During the past 50 years, plantation Christmas tree production has grown in acreage and sophistication. Nitrogen applications with a tuna can have been replaced by precise, mechanized application of a wide array of nutrients and lime. Current nutrient management programs must focus on three concepts for success. This guide provides...
