Motivated by observations of locally enhanced sea level variability near steep
topographic slopes in regions of strong time-mean flows, effects of zonal ridge topography
on zonal oceanic jet flow are investigated. Unstable wave properties and the...

Shear waves, which are instabilities of the longshore current, are of interest
to nearshore research because they can act as a cross-shore mixing mechanism
for the current. The best method to study them is in a controlled environment,
such as...

Global climate change is projected to have far-ranging effects on the oceans and
marine life. In turn, fisheries will likely undergo changes in their distributions and
abundance. Coastal Alaskan communities are often highly dependent on...

Collocated Moderate Resolution Imaging Spectroradiometer (MODIS) imagery and
Cloud‐Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) 532 nm
total attenuated backscatter coefficients were used to identify 50 km scale segments...

Electric and magnetic fields in the (10−4–1.0) Hz band were monitored at two sites
adjacent to the San Andreas Fault near Parkfield and Hollister, California, from 1995 to
2007. A data window (2002–2005), enclosing the 28 September 2004 M6...

Ocean acidification is predicted to occur first in polar oceans. We investigated the
saturation state of waters with respect to calcite (Wcal) and aragonite (Warg) in six sections
along an Arctic outflow pathway through the Canadian Arctic...

In 2002, oxygen isotope ratios of water (H2
18O/H2
16O), dissolved barium, and salinity were
measured in surface waters around northern North America to identify freshwater sources and to
provide a large-scale background for interpretation of...

The floating ice shelf of Petermann glacier interacts directly with the ocean and is
thought to lose at least 80% of its mass through basal melting. Based on three opportunistic
ocean surveys in Petermann Fjord we describe the basic oceanography:...

We estimate the depth of the 120°C isotherm by constructing crustal thermal gradients based on theoretical
and observed conductive heat flux as a function of lithospheric age. We chose the 120°C isotherm because it is
close to the upper limit for...

These first measurements of specific surface area (SSA)
of bulk samples of subsurface marine basalts were undertaken
to determine the potential area available for microbial
colonization. SSA ranged from 0.3 to 52 m2/g of basalt
with the lowest...

Outcrops of old strata at the shelf edge resulting from erosive gravity‐driven flows
have been globally described on continental margins. The reexposure of old strata allows
for the reintroduction of aged organic carbon (OC), sequestered in marine...

A finite difference scheme is employed to solve the
integral form of the momentum, continuity and heat
equations, for a two layer ocean bounded by a coastline.
The momentum equations include the turbulent dynamics and
the time-dependent and...

Knowledge of frictional resistance along faults is important for understanding the
mechanics of earthquakes and faulting. The clearest in situ measure of fault friction
potentially comes from temperature measurements in boreholes crossing fault...

Borehole temperature profiles provide a record of ground surface temperature (GST)
change at the decadal to centennial time scale. GST histories reconstructed from boreholes
are particularly useful in climate reconstruction if changes in GST and...

The thermal structure of convergent margins provides information related to the tectonics, geodynamics,
metamorphism, and fluid flow of active plate boundaries. We report 176 heat flow measurements
made with a violin bow style probe across the...

At the Costa Rica margin along the Middle America Trench along‐strike variations in heat flow are well
mapped. These variations can be understood in terms of either ventilated fluid flow, where exposed basement
allows fluids to freely advect heat...

Sea level and wind data from coastal and island stations from
Buenaventura, Colombia (4°N) to Callao, Peru (12°S) have been
analyzed for the 1979-1984 time period, to describe the seasonal and
interannual variations in the characteristics of short...

A nonlinear model is developed to study the time‐dependent relationship between the
alongshore variability of a sandbar, a(t), and alongshore‐averaged sandbar position, xc(t).
Sediment transport equations are derived from energetics‐based...

Large rivers represent gateways for the transport of
terrigenous and anthropogenic material to the coastal ocean.
Here we document a ∼700 km2 recirculation or bulge associated
with the Columbia River plume that retains recently discharged
river...

Synchronous and colocated optical and microwave
signals from waves in the surf zone are presented and analyzed.
The field data were collected using a high-resolution video system

Three‐dimensional circulation in the coastal transition zone (CTZ) off Oregon is

The effects of five data processing methods on the accuracy of
geostrophic computations are analyzed using hydrographic data collected
from a set of 24 hour triangular stations off the Oregon coast.
Sources of error are assessed by comparison with...
