The life cycles of three Madden–Julian oscillation (MJO) events were observed over the Indian Ocean as part of the Dynamics of the MJO (DYNAMO) experiment. During November 2011 near 0°, 80°E, the site of the research vessel Roger Revelle, the...

In order to better understand the general problem of satellite cloud top height
retrievals for low clouds, observations made by NOAA research vessels in the
stratocumulus region in the southeastern Pacific during cruises in 2001 and 2003 to 2006...

DYNAMO and TOGA-COARE observations and reanalysis-based surface flux products are
used to test theories of atmosphere-ocean interaction that explain the Madden-Julian
Oscillation (MJO). Negative intraseasonal outgoing longwave radiation,...

Air-sea interaction at ocean fronts and eddies exhibits positive correlation
between sea surface temperature (SST), wind speed, and
heat fluxes out of the ocean, indicating that the ocean is forcing the
atmosphere. This contrasts with larger scale...

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...

To measure organismal coherence in a pelagic ecosystem, we used moored sensors to describe the vertical dynamics of
each step in the food chain in shelf waters off the west shore of Oahu, Hawaii. Horizontally extensive, intense aggregations
of...

As in many regions of the world, the shelf waters of the western United States have
experienced large increases and high interannual variability in jellyfish populations in recent
decades. The northern California Current (NCC) is a productive...

The Cobb Seamount Chain in the northeast Pacific basin records the composition of the Cobb
hot spot for the past 33 Myr, as the migrating Juan de Fuca Ridge approached and ultimately overran it ca.
0.5 Myr ago. In this first comprehensive...

Submarine landslides are an important process in volcano growth yet are rarely observed and
poorly understood. We show that landslides occur frequently in association with the eruption of West
Mata volcano in the NE Lau Basin. These events are...

The Coastal Storm Modeling System (CoSMoS) applies a predominantly
deterministic framework to make detailed predictions (meter scale) of storm-induced
coastal flooding, erosion, and cliff failures over large geographic scales (100s of...

The results presented in this dissertation address a number of questions regarding late Pleistocene and Holocene ice-sheet and climate interactions, spanning disciplines involving paleoclimatology and atmospheric science. These studies use various...

Summer streamflows in the Pacific Northwest are
largely derived from melting snow and groundwater discharge.
As the climate warms, diminishing snowpack and
earlier snowmelt will cause reductions in summer streamflow.
Most regional-scale...

Large earthquakes on mid-ocean ridge transform faults are
commonly preceded by foreshocks[superscript 1–3] and changes in the
seismic properties of the fault zone³. These seismic precursors
could be linked to fluid-related processes[superscript...

Adaptive governance is an emergent form of environmental governance that is increasingly called upon by scholars and
practitioners to coordinate resource management regimes in the face of the complexity and uncertainty associated with rapid...

Mesoscale fronts occur frequently in many coastal areas and often are sites of elevated
productivity; however, knowledge of the fine-scale distribution of zooplankton at these
fronts is lacking, particularly within the mid-trophic levels....

In late 2007, two massive icebergs, C19a and B15a, drifted into open water and slowly disintegrated
in the southernmost Pacific Ocean. Archived acoustic records show that the high-intensity underwater
sounds accompanying this breakup increased...

Relative to extensive research on the freshwater stages of steelhead Oncorhynchus mykiss life history, little is
known about the species’ estuarine and early marine phases despite the decline of numerous populations, including
several from the...

The inaccessibility of open ocean habitat and the cryptic nature of small
animals are fundamental problems when assessing the distribution of
oceanic-stage sea turtles and other marine animals sharing similar life-history
traits. Most methods that...

We manipulated food inputs among patches within experimental streams to
determine how variation in foraging behavior influenced demographic and phenotypic
responses of juvenile steelhead trout (Oncorhynchus mykiss) to the spatial predictability...

The feeding habits of pelagic, juvenile rockfishes
(Sebastes spp.) collected off Oregon in 2002, and Oregon
and Washington in 2006, were examined using stomach
content and stable isotope analyses. Sampling occurred

The status of the double-crested cormorant (Phalacrocorax auritus) in western North
America was last evaluated during 1987–2003. In the interim, concern has grown over the potential
impact of predation by double-crested cormorants on juvenile...

We estimated annual survival rates (S) of 23 radio-marked Northern Spotted Owls (Strix occidentalis
