2010, Report, Oregon Climate Assessment Report (OCAR, 2010)
Earth’s changing climate is expected to have significant physical impacts along the coast and estuarine shorelands of Oregon, ranging from increased erosion and inundation of low lying areas, to wetland loss and increased estuarine salinity. The environmental changes associated with climate change include rising sea levels, increased occurrences of severe...
Environmental investigations using diatom microfossils
Kathryn E. L. Smith, James G. Flocks
2010, Fact Sheet 2010-3115
Diatoms are unicellular phytoplankton (microscopic plant-like organisms) with cell walls made of silica (called a frustule). They live in both freshwater and saltwater and can be found in just about every place on Earth that is wet. The shape and morphology of the diatom frustule unique to each species are...

Christopher F. Smith, Jeffrey T. Cordova, Stephen M. Wiele
2010, Scientific Investigations Report 2010-5241
The continuous slope-area (CSA) method expands the slope-area method of computing peak discharge to a complete flow event. Continuously recording pressure transducers installed at three or more cross sections provide water-surface slopes and stage during an event that can be used with cross-section surveys and estimates of channel roughness to...
Use of acoustic backscatter and vertical velocity to estimate concentration and dynamics of suspended solids in Upper Klamath Lake, south-central Oregon: Implications for Aphanizomenon flos-aquae
Tamara M. Wood, Jeffrey W. Gartner
2010, Scientific Investigations Report 2010-5203
Vertical velocity and acoustic backscatter measurements by acoustic Doppler current profilers were used to determine seasonal, subseasonal (days to weeks), and diel variation in suspended solids in a freshwater lake where massive cyanobacterial blooms occur annually. During the growing season, the suspended material in the lake is dominated by the...
An integrated sampling and analysis approach for improved biodiversity monitoring
Amielle A. DeWan, Elise F. Zipkin
2010, Environmental Management (45) 1223-1230
Successful biodiversity conservation requires high quality monitoring data and analyses to ensure scientifically defensible policy, legislation, and management. Although monitoring is a critical component in assessing population status and trends, many governmental and non-governmental organizations struggle to develop and implement effective sampling protocols and statistical analyses because of the magnitude...

Puget Sound shorelines and the impacts of armoring: Proceedings of a state of the science workshop, May 2009
Hugh Shipman, Megan N. Dethier, Guy R. Gelfenbaum, Kurt L. Fresh, Richard S. Dinicola, editor(s)
2010, Scientific Investigations Report 2010-5254
The widespread extent and continued construction of seawalls and bulkheads on Puget Sound's beaches has emerged as a significant issue in shoreline management and coastal restoration in the region. Concerns about the impacts of shoreline armoring and managing the potential risks to coastal property are in many ways similar to...

2010, Open-File Report 2010-1276
Watersheds play many important roles in the carbon cycle: (1) they are a site for both terrestrial and aquatic carbon dioxide (CO2) removal through photosynthesis; (2) they transport living and decomposing organic carbon in streams and groundwater; and (3) they store organic carbon for widely varying lengths of time as...

The restoration of 18 acres of historic tidal marsh at Crissy Field has had great success in terms of public outreach and visibility, but less success in terms of revegetated marsh sustainability. Native cordgrass (Spartina foliosa) has experienced dieback and has failed to recolonize following extended flooding events during unintended...
