Relationships of density, microfibril angle, and sound velocity with stiffness and strength in mature wood of Douglas-fir

Creator:: Lachenbruch, Barbara, Johnson, G. R., Downes, G., and Evans, R.
Abstract:: The relative importance of density, acoustic velocity, and microfibril angle (MFA) for the prediction of the stiffness (MOE) and strength (MOR) has not been well established for Douglas-fir (Pseudotsuga menziesii). MOE and MOR of small clear specimens of mature wood were better predicted by density and velocity than by either...

Regional to global assessments of phytoplankton dynamics from the SeaWiFS mission

Creator:: Siegel, D. A., Behrenfeld, Michael J., Maritorena, S., McClain, C. R., Antoine, D., Bailey, S. W., Bontempi, P. S., Boss, E. S., Dierssen, H. M., Doney, S. C., Eplee, R. E. Jr., Evans, R. H., Feldman, G. C., Fields, E., Franz, B. A., Kuring, N. A., Mengelt, C., Nelson, N. B., Patt, F. S., Robinson, W. D., Sarmiento, J. L., Swan, C. M., Werdell, P. J., Westberry, T. K., Wilding, J. G., and Yoder, J. A.
Abstract:: Photosynthetic production of organic matter by microscopic oceanic phytoplankton fuels ocean ecosystems and contributes roughly half of the Earth's net primary production. For 13 years, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) mission provided the first consistent, synoptic observations of global ocean ecosystems. Changes in the surface chlorophyll concentration, the primary...

Abstract:: As managers of agricultural and natural resources are confronted with uncertainties in global change impacts, the complexities associated with the interconnected cycling of nitrogen, carbon, and water present daunting management challenges. Existing models provide detailed information on specific sub-systems (e.g., land, air, water, and economics). An increasing awareness of the...

Hydrothermal activity in the Northwest Lau Backarc Basin: Evidence from water column measurements

Creator:: Lupton, J. E., Arculus, R. J., Resing, J., Massoth, G. J., Greene, R. R., Evans, L. J., and Buck, N.
Abstract:: The Northwest Lau Backarc Basin, consisting of the Northwest Lau Spreading Center (NWLSC) and the Rochambeau Rifts (RR), is unique in having elevated ³He/⁴He ratios (up to 28 R[subscript a]) in the erupted lavas, clearly indicating a hot spot or ocean island basalt (OIB)-type signature. This OIB-type helium signature does...

Invaded range of the blackberry pathogen Phragmidium violaceum in the Pacific Northwest of the USA and the search for its provenance

Creator:: Morin, Louise, Gomez, Don R., Evans, Katherine J., Neill, Tara M., Mahaffee, Walt F., and Linde, Celeste C.
Abstract:: Field surveys in 2006 confirmed that the exotic rust fungus Phragmidium violaceum was widespread on Rubus armeniacus and Rubus laciniatus in the Pacific Northwest of the USA. The origin and dispersal pattern of this obligate biotrophic pathogen in the USA were investigated by comparing the genetic diversity and structure of...

Abstract:: The Moderate Resolution Imaging Spectroradiometer (MODIS) will add a significant new capability for investigating the 70% of the Earth's surface that is covered by oceans, in addition to contributing to the continuation of a decadal scale time series necessary for climate change assessment in the oceans. Sensor capabilities of particular...

Abstract:: Coastal upwelling regimes are some of the most productive ecosystems in the ocean but are also among the most vulnerable to ocean acidification (OA) due to naturally high background concentrations of CO₂. Yet our ability to predict how these ecosystems will respond to additional CO₂ resulting from anthropogenic emissions is...

Assessing and addressing the re-eutrophication of Lake Erie: Central basin hypoxia

Creator:: Scavia, Donald, Allan, J. David, Arend, Kristin K., Brandt, Stephen B., Bartell, Steven, Bosch, Nate S., Briland, Ruth D., Daloğlu, Irem, DePinto, Joseph V., Dolan, David M., Evans, Mary Anne, Farmer, Troy M., Goto, Daisuke, Han, Haejin, Höök, Tomas O., Knight, Roger, Ludsin, Stuart A., Mason, Doran, Michalak, Anna M., Richards, R. Peter, Roberts, James J., Rucinski, Daniel K., Rutherford, Edward, Schwab, David J., Sesterhenn, Timothy M., Zhang, Hongyan, and Zhou, Yuntao
Abstract:: Relieving phosphorus loading is a key management tool for controlling Lake Erie eutrophication. During the 1960s and 1970s, increased phosphorus inputs degraded water quality and reduced central basin hypolimnetic oxygen levels which, in turn, eliminated thermal habitat vital to cold-water organisms and contributed to the extirpation of important benthic macroinvertebrate...
