A sequence of volcanic, volcaniclastic, and epiclastic deposits from Oligocene to Recent age are exposed in the region from Lake
Simtustus to Madras in central Oregon. The epiclastic sediments of the Oligocene John Day Formation are unconformably overlain by two flows of the middle Miocene Columbia River Basalt Group. The...
This project was carried out collaboratively by Oregon State University (OSU) and the Oregon Department of Geology and Mineral Industries (DOGAMI) and involved baseline observations and
modeling at the proposed wave energy conversion (WEC) array site near Reedsport, OR. In particular, observations and predictions of the wave conditions at the...

We inferred the population densities of blue whales (Balaenoptera musculus) and short-beaked
common dolphins (Delphinus delphis) in the Northeast Pacific Ocean as functions
of the water-column’s physical structure by implementing hierarchical models in a Bayesian
framework. This approach allowed us to propagate the uncertainty of the field observations
into the...

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...

Significant seabird mortality on the Oregon (OR) and Washington (WA) coast in 2009 has been attributed
to a massive bloom of the dinoflagellate Akashiwo sanguinea (K. Hirasaka) G. Hansen & Ø. Moestrup.
Initial, albeit limited, observations suggested this bloom began in WA and reached OR waters through
southward transport. Here,...
While bubble plumes have been acoustically imaged in the water column above marine gas
hydrate deposits in many studies, little is known about the temporal variation in plume intensity. In
July 2008, we conducted surveys using 3.5 and 12 kHz echosounders and a 75 kHz acoustic Doppler
current profiler (ADCP)...
The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics)
program examined zooplankton populations and their predators in four coastal
marine ecosystems. Program scientists learned that environmental controls on
zooplankton vital rates, especially the timing and magnitude of reproduction, growth,
life-cycle progression, and mortality, determine species population dynamics,
seasonal and spatial distributions,...
A variety of approaches are used in sagebrush conservation. The Sagebrush/Sage Grouse Habitat Metric is one of several ecological measures that have been developed to help managers determine where to invest limited resources and how to calculate the ecological impact and improvement associated with the implementation of conservation actions.

The last deglaciation of the Scandinavian Ice Sheet (SIS) from ∼21,000 to 13,000 yr ago is well-constrained by several hundred ¹⁰Be and ¹⁴C ages. The subsequent retreat history, however, is established primarily from minimum-limiting ¹⁴C ages and incomplete Baltic-Sea varve records, leaving a substantial fraction of final SIS retreat history...

The filamentous fungus Neurospora crassa responds to light in complex ways. To thoroughly
study the transcriptional response of this organism to light, RNA-seq was used to analyze capped and
polyadenylated mRNA prepared from mycelium grown for 24 hr in the dark and then exposed to light for
0 (control) 15,...

The Mount Fubilan Intrusion is part of a geologically young hypabyssal stock in the Star Mountains of Papua New Guinea. This stock was mapped as the Ok Tedi Intrusive Complex and divided into four separate bodies: the Mount Fubilan, Sydney Intrusion, Kalgoorlie, and Ningi Intrusions. Hydrothermal fluids caused alteration of...
The three studies that comprise this dissertation seek to answer significant
questions in paleoclimatology through unconventional applications of ice core
greenhouse gas data. These studies involve different gases and span the interval of time
between the Last Glacial Maximum and the Industrial Revolution, but are united by their
nontraditional use...
