Improvements in pollutant monitoring: Optimizing silicone for co-deployment with polyethylene passive sampling devices

Creator:: O'Connell, Steven G., McCartney, Melissa A., Paulik, L. Blair, Allan, Sarah E., Tidwell, Lane G., Wilson, Glenn, and Anderson, Kim A.
Abstract:: Sequestering semi-polar compounds can be difficult with low-density polyethylene (LDPE), but those pollutants may be more efficiently absorbed using silicone. In this work, optimized methods for cleaning, infusing reference standards, and polymer extraction are reported along with field comparisons of several silicone materials for polycyclic aromatic hydrocarbons (PAHs) and pesticides....

A guide to collecting soil samples for farms and gardens

Creator:: Fery, Melissa, Murphy, E. (Elizabeth Carrington), and Oregon State University. Extension Service
Abstract:: Laboratory soil tests help you develop and maintain more productive soil and increase crop production by providing information on the available nutrient content of your soil. Soil testing helps you select the correct kind and amount of fertilizer and liming material. Recommendations are based on the results of fertilizer experiments,...

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...

Juneau Wetland Management Plan 2016 Update : Final Report : Volume 1

Creator:: Bosworth Botanical Consulting and Adamus, Paul R.
Abstract:: The Juneau Wetland Management Plan (JWMP), Volume 1, provides results of wetlands mapping and wetland functional assessments for currently undeveloped parcels within the City and Borough of Juneau (CBJ). The study areas were selected for their potential for future development based on low elevation and proximity to existing infrastructure. During...

Juneau Wetland Management Plan 2016 Update Volume 2 : Scores and Maps by Assessment Area

Creator:: Bosworth Botanical Consulting and Adamus, Paul R.
Abstract:: Contains ground-truthed wetland maps and scores representing ecosystem services of a large portion of the wetlands in Juneau, Alaska. LiDAR imagery was used extensively.

Precision of the current methods to measure the alkenone proxy U₃₇ K’ and absolute alkenone abundance in sediments: results of an interlaboratory comparison study

Creator:: Rosell-Melé, A., Bard, E., Emeis, K.-C., Grimalt, J. O., Muller, P., Schneider, R., Bouloubassi, I., Epstein, B., Fahl, K., Fluegge, A., Freeman, K., Goñi, M., Güntner, U., Hartz, D., Hellebust, S., Herbert, T., Ikehara, M., Ishiwatari, R., Kawamura, K., Kenig, F., de Leeuw, J., Lehman, S., Mejanelle, L., Ohkouchi, N., Pancost, R. D., Pelejero, C., Prahl, Fredrick, Quinn, J., Rontani, J.-F., Rostek, F., Rullkötter, J., Sachs, J., Blanz, T., Sawada, K., Schulz-Bull, D., Sikes, E., Sonzogni, C., Ternois, Y., Versteegh, G., Volkman, J. K., and Wakeham, S.
Abstract:: Measurements of the U₃₇ K’ index and the absolute abundance of alkenones in marine sediments are increasingly used in paleoceanographic research as proxies of past sea surface temperature and haptophyte (mainly coccolith-bearing species) primary productivity, respectively. An important aspect of these studies is to be able to compare reliably data...

Effects of forest roads and tree removal in or near wetlands of the Pacific Northwest : a literature synthesis

Creator:: Adamus, Paul R.
Abstract:: Because studies of forestry effects on wetlands have been so infrequent in the Pacific Northwest, each section in this report drew heavily from studies of forestry impacts to streams and riparian zones. After assembly and synthesis, that information was extrapolated, mostly in the form of hypotheses, to the very different...

Behavioral Thresholds in Mixtures of Sand and Kaolinite Clay

Creator:: Simpson, D. C. and Evans, T. M.
Abstract:: Nearly all soils are comprised of mixtures of coarse and fine particles. Behavior under mechanical and thermal loading of soil is strongly influenced, and in some cases governed, by the ratio of coarse to fine particles. A better understanding of the fundamental behavior of soil mixtures will provide insight to...

Hillslope run-off thresholds with shrink-swell clay soils

Creator:: Stewart, Ryan D., Abou Najm, Majdi R., Rupp, David E., Lane, John W., Uribe, Hamil C., Luis Arumí, José, and Selker, John S.
Abstract:: Irrigation experiments on 12 instrumented field plots were used to assess the impact of dynamic soil crack networks on infiltration and run-off. During applications of intensity similar to a heavy rainstorm, water was seen being preferentially delivered within the soil profile. However, run-off was not observed until soil water content...

Threshold Management in A Coupled Economic-Ecological System

Creator:: Chen, Yong, Jayaprakash, Ciriyam, and Irwin, Elena
Abstract:: Economic analysis of optimal ecosystem management in the presence of a threshold has typically ignored the potential for induced behavioral responses. This paper contributes to the literature on non-convex ecosystem management by considering the implications of a particular behavioral response in a regional economy - that of amenity-led growth -...
