Subduction zone earthquake and tsunami hazards affect tens of millions worldwide and the recurrence of these disasters can be evaluated with paleoseismic techniques, because earthquake cycles (and their supercycles) typically span many millennia. In these three chapters, I discuss a suite of analyses I use to evaluate the sedimentary record...

The southern half of the upper Nehalem River basin contains
the most complete section of lower to middle Tertiary marine sedimentary
and volcanic rocks in northern Oregon. Determination of
stratigraphic relationships of six formations, and their depositional
environments and provenance is the chief objective of this paper.
More than 75...

AN ABSTRACT OF THE THESIS OF
ROBERT OTIS VAN ATTA for the DOCTOR. OF
Variable ocean conditions can greatly impact
prey assemblages and predator foraging in marine ecosystems.
Our goal was to better understand how a change in
ocean conditions influenced dietary niche overlap among
a suite of midtrophic-level predators. We examined the
diets of three fishes and one seabird off central Oregon
during...

Understanding the causes and consequences of rapid environmental change is an essential scientific frontier, particularly given the threat of climate-and land use-induced changes in disturbance regimes. In western North America, recent widespread insect outbreaks and wildfires have sparked acute concerns about potential insect-fire interactions. Although previous research shows that insect...

Siletzia is a basaltic Paleocene and Eocene
large igneous province in coastal Oregon,
Washington, and southern Vancouver Island
that was accreted to North America in the
early Eocene. New U-Pb magmatic, detrital
zircon, and ⁴⁰Ar/³⁹Ar ages constrained by
detailed field mapping, global nannoplankton
zones, and magnetic polarities allow correlation
of...

Many endemic species, particularly those on
remote islands, have been driven to extinction or near extinction
by anthropogenic influences. The short-tailed albatross
Phoebastria albatrus once numbered in the millions
but was thought to be extinct by the mid 20th century.
Albatrosses, of the family Diomedeidae, are among the most
threatened...

Background:
Previous studies of compatibility of calcium chloride (CaCl₂) and phosphates have not included particle counts in the range specified by the United States Pharmacopeia. Micro-flow imaging techniques have been shown to be comparable to light obscuration when determining particle count and size in pharmaceutical solutions.
Objective:
The purpose of...

Sensory hair cells convert mechanical motion into chemical signals. Otoferlin, a six-C2 domain transmembrane protein linked to deafness in humans, is hypothesized to play a
role in exocytosis at hair cell ribbon synapses. To date however, otoferlin has been
studied almost exclusively in mouse models, and no rescue experiments have...

Background:
The people of Bangladesh are currently exposed to high concentrations of arsenic and manganese in drinking water, as well as elevated lead in many regions. The objective of this study was to investigate associations between environmental exposure to these contaminants and neurodevelopmental outcomes among Bangladeshi children.
Methods:
We evaluated...
