A miniature thermistor chain (mTc) was developed to measure the subdiurnal variability of temperature in
the upper layers of subtidal coastal permeable (sandy) sediments and across the sediment-water interface (SWI).
The mTc has 15 precision...

Shore-based video remote sensing is used to observe and continually monitor nonlinear internal waves
propagating across the inner shelf. Month-long measurements of velocity from bottom-mounted acoustic
Doppler current profilers and temperature...

This article presents the results of a high-resolution (1/12°), two-way nested simulation of the
oceanic circulation in the southwestern Atlantic region. A comparison between the model results and
extant observations indicates that the nested...

The implicit particle filter is applied to a stochastically forced shallow water model of nearshore
flow, and found to produce reliable state estimates with tens of particles. The state vector of this model consists
of a height anomaly and two...

A Rutan Aircraft Factory Long-EZ aircraft flew numerous low-level slant soundings on two summer days in
2001 off the northeastern coast of the United States. The soundings are analyzed here to study the nonstationary
vertical structure of the...

Topographically generated eddies and internal waves have traditionally been studied separately
even though bathymetry that creates both phenomena is abundant in coastal regions. Here a numerical
model is used to understand the dynamics of eddy and...

Bathymetry is a major factor in determining nearshore and surf zone wave transformation and
currents, yet is often poorly known. This can lead to inaccuracy in numerical model predictions. Here
bathymetry is estimated as an uncertain parameter in...

Scatterometer ocean surface winds have been providing very valuable information to researchers and operational
weather forecasters for over 10 years. However, the scatterometer wind retrievals are compromised when
rain is present. Merely flagging...

A central challenge for natural resource management is developing rigorous yet practical approaches for balancing the costs and benefits of diverse human uses of ecosystems. Economic theory has a long history of evaluating tradeoffs in returns...

Projections of a drier, warmer climate in the U.S. Southwest would complicate
management of the Colorado River system – yet these projections, often based on coarse
resolution global climate models, are quite uncertain. We present an approach to...

Inherited age is defined herein as the difference between times of carbon fixation in a material and deposition
of that material within sediments from which it is eventually sampled in order to estimate deposit age via
radiocarbon dating....

The concept of "adaptive governance" represents a spectrum of hybrid approaches to environmental governance employed to guide management of complex social-ecological systems under conditions of high uncertainty. While the concept of adaptive...

During the summer of 1996, I had the opportunity to do an internship with the
Florida Keys National Marine Sanctuary (FKNMS) at Lower Key Office, Key West,
Florida. Established in November 1990 under the Florida Keys National Marine
Sanctuary and...

Cosmogenic-burial and U-series dating, identification of fluvial terraces and lacustrine
deposits, and river-profile reconstructions show that capture of the Gunnison River by
the Colorado River and abandonment of Unaweep Canyon occurred between...

Two modifications to an existing scheme of tidal
mixing are implemented in the coarse resolution ocean component
of a global climate model. First, the vertical distribution
of energy flux out of the barotropic tide is determined
using high...

The upper reach of the Hutuo River flows along the Xin-Ding basin and cuts a transverse drainage
through Xizhou Mountain and Taihang Range into the North China Plain. Previous studies showed
that the Xin-Ding basin was occupied by a lake during...

The undertow is one of the most important mechanisms for sediment transport in
nearshore regions. As such, its formulation has been an active subject of research for
at least the past 40 years. Still, much debate persists on the exact nature of...

To date, academic research relating to Marine Renewable Energy (MRE) has largely focused
on resource assessment, technical viability and environmental impact. Experiences from
onshore renewable energy tell us that social acceptability is equally...

Pleistocene drainage basin integration led to progressive excavation of
Tertiary-Quaternary sedimentary basins along the Yellow River in the northeastern Tibetan
Plateau. Cosmogenic burial dating of ancestral river deposits and basin fill from two...

Altar (31º 29’ S, 70º 28’ W) is a large porphyry Cu-(Au-Mo) deposit with associated
epithermal Au-(Ag-Cu) veins located in the Cordillera Principal of SW San Juan Province
(Argentina). Altar is a complex magmatic-hydrothermal system formed from...

From December 2006 to November 2011, the Pacific Northwest Seismic Network (PNSN)
reported 467 earthquakes in a swarm 60 km east of Mt Hood near the town of Maupin, Oregon.
The swarm included 20 M[subscript D] ≥ 3.0 events, which account for over...

How does transboundary water cooperation begin at the initial stages? Countries in many transboundary basins either do not cooperate at all or have ceased cooperation altogether. Yet cooperation does often prevail, resulting in 688 water-related...

The lakes, rivers and coastal waters of Oregon have long provided the state's residents

We report ³He/⁴He for 150 mid-ocean ridge basalt (MORB) glasses from the Southeast Indian
Ridge (SEIR). Between 81°E and 101°E ³He/⁴He varies from 7.5 to 10.2 R[subscript A], encompassing more than half the
MORB range away from ocean island hot...
