Conductivity-temperature-depth surveys during 1988 encountered strong baroclinic jets that were evident in
acoustic Doppler current profiler and hydrographic data. During June and July 1988 a filament with high surface
nitrate, high chlorophyll,...

Moored observations of currents and temperatures made in the upper 600 m on
eddy-resolving scales over a 2-year period are used to examine the spatial and temporal
characteristics of the California Current mesoscale circulation. The observations...

Two mesoscale surveys were conducted (in July 1981 and July 1982) near Point Arena, California, to
determine the structure and circulation associated with tongues of cold surface water extending seaward
from the coastal zone. Both surveys were...

In 2005, the onset of spring conditions in the physics
of the coastal ocean (lowered sea level, spin-up of
vertically-sheared equatorward coastal jet) came about 50
days later than average off Newport Oregon, on May 24.
There was a further delay...

Moored current measurements from the Oregon shelf
during 1998–2003 are used to estimate time series of
anomalous alongshore currents and pseudo-displacements,
after accounting for the mean and seasonal cycle. From
early January through mid-June,...

For 74 days during the spring and summer upwelling seasons of 1981 and 1982, in conjunction with
the Coastal Ocean Dynamics Experiment, profiles of upper ocean currents were collected in the waters
over the shelf and slope off northern California...

A time series of hourly surface current maps in the shelf waters off Newport, Oregon,
was made during April–September 2001 using five SeaSonde HF current mappers, during
Coastal Advances in Shelf Transport (COAST). The surface currents responded...

Since the early surveys carried out by the Eastern Tropical Pacific (EASTROPIC)
and Scripps Tuna Oceanographic Research (STOR) projects in the tropical Pacific off
Mexico, the northerly winds which blow over the Gulf of Tehuantepec were described...

Observations during the Coastal Transition Zone (CTZ) experiment in summer 1988 reveal the
presence of deep phytoplankton layers in a coastal upwelling system. The layers occur throughout the
CTZ study area, including a strong baroclinic jet which...

An experiment in 199 m of water on the Oregon shelf produced continuous current speed profiles
down to the sediment-water interface. These profiles show that the velocity structure above the
viscous sublayer is consistent with that expected when...

Experiments conducted on the Oregon continental shelf in June 1979 indicate that the boundary layer
flow at the seafloor was hydrodynamically smooth. Fine-resolution velocity profiles are used to test the
assumption that the flow behaved like a...

Observations of vertical temperature microstructure at ocean station P during the mixed layer experiment (Mile) indicate that the shape of the high-frequency temperature gradient spectrum depends on the
relative strengths of turbulence and...

Slow perturbations of the drop speed of a nearly freely falling, winged, microstructure probe in the upper
200 m at station P are interpreted as vertical velocity fluctuations of an internal wave field. The frequencies of these fluctuations lie in...

A 38-day, 5990-cast microstructure study on the equator performed
during the onset of the 1991-1993 El Nino shows the effect on small-scale activity
at 140°W of an equatorial Kelvin wave. By using two ships, data were taken
continuously from...

An inertial subrange was found in spectra calculated from vertical profiles of temperature gradient recorded in the bottom boundary layer of the Oregon shelf. Spectra were calculated for 53-cm vertical segments. An ensemble average of those...

Nondimensionalized equations of motion for waterdrops, not necessarily obeying Stokes's
law, are derived and used to calculate the response of various size drops to changes in horizontal
wind speed. We find that (1) cloud drops respond almost...

Tests of a formula derived for the cutoff wave number of vertical temperature gradient spectra, using
data taken in the upper layers of the North Pacific, show encouraging results. To derive this formula, the
cutoff wave number is assumed to be...

A test of the scaling of the extent of the thinnest vertical temperature gradients, in the near-bottom
boundary layer on the Oregon shelf, shows that the Batchelor wave number determines the cutoff wave
number in vertical temperature gradient...

A light, simple, and fairly inexpensive hand-launched freely falling probe for measuring temperature microstructure was built. The circuitry operates under pressure in a Freon environment; low-power integrated circuits are used as components. The...

As shallow water is approached via a steep lake-bottom slope, increased mixing of heat is indicated by the presence of a highly “stepped” temperature profile. This mixing activity operates over a wide range of vertical scales.
