The upward flux of heat from the subsurface core of Warm Deep Water
(WDW) to the perennially ice-covered sea surface over the continental slope in the
western Weddell Sea is estimated using data obtained during February-June 1992
from a drifting ice station. Through the permanent pycnocline the diapycnal heat
flux...
A statistical description of the deep ocean internal wave field is presented using measurements from the Midocean Acoustic Transmission Experiment, conducted near Cobb Seamount in the NE Pacific (46°46'N, 30°47'W) during June–July 1977. The unique feature of this experiment is the variety of data obtained simultaneously from the same location:...
The upper ocean current and temperature fields in the western Weddell Sea were measured from the drifting pack ice at Ice Station Weddell 1 (ISW) and nearby sites using a vertical profiler and an array of moored sensors in January–June 1992. These data document the structure and variability of the...
Internal gravity waves measured under the Arctic pack ice were strikingly different from measurements
at lower latitudes. The total wave energy, integrated over the internal wave frequency band, was lower by
a factor of 0.03-0.07, and the spectral slope at high frequency was nearly -1 in contrast to the -2...
Observations, from the Oregon continental shelf, describe the slumping of a coastal
upwelling front in response to a reversal of winds from upwelling-to downwelling-favorable.
Initially, the front outcropped in a surface mixed layer of depth 10–20 m with a
pronounced cross-shelf density gradient. Following wind reversal, both the unbalanced
cross-shelf...
Hydrographic and velocity profiles were made through a small baroclinic cyclonic eddy during the Arctic Internal Wave Experiment in the Canada Basin in April 1985. The maximum measured azimuthal velocity was 0.38 m s⁻¹ at a depth of 115 m, with velocities decaying to near zero at 30 and 270...
The upwelling-driven coastal jet off Oregon is in geostrophic balance to first order.
The accompanying thermal wind shear is stable to shear instability. Yet enhanced
turbulence is observed in the upwelling jet, typically as long, thin patches with horizontal
to vertical aspect ratios of 10² to 10³ (median value ~300)....
In this paper, we evaluate the temporal and horizontal resolution of geostrophic
surface velocities calculated from TOPEX satellite altimeter heights. Moored velocities
(from vector-averaging current meters and an acoustic Doppler current profiler) at depths
below the Ekman layer are used to estimate the temporal evolution and accuracy of
altimeter geostrophic...
Horizontal current measurements from an array of moored acoustic Doppler profilers are assimilated sequentially into a model of coastal wind-driven circulation off Oregon during the upwelling season of May–August 2001. Model results are compared against independent moored and ship survey data to document a positive effect of velocity data assimilation...
Near the bottom, the velocity profile in the bottom boundary layer over the continental
shelf exhibits a characteristic law-of-the-wall that is consistent with local estimates of
friction velocity from near-bottom turbulence measurements. Farther from the bottom, the
velocity profile exhibits a deviation from the law-of-the-wall. Here the velocity gradient
continues...
