Shelf break conditions and alongshore flow off northwestern Australia are studied
during the strongly evaporative conditions of austral winter 2003. Present results,
along with those of previous authors, confirm that a poleward, fresh Leeuwin current core
is normally found near the shelf break. Salinity increases alongshore toward the
southwest. Although...
Austral winter oceanographic measurements from the
northwest Australian continental shelf reveal salty water
forming evaporatively inshore, moving across the wide
shelf near the bottom and into the adjacent open ocean when
the shelf edge alongshore flow is equatorward. The salt
tongue is absent during more normal conditions, when the
poleward...

Several diagnoses of three-dimensional circulation, using density and velocity data from a high-resolution, upper-ocean SeaSoar and acoustic Doppler current profiler (ADCP) survey of a cyclonic jet meander and adjacent cyclonic eddy containing high Rossby number flow, are compared. The Q-vector form of the quasigeostrophic omega equation, two omega equations derived...
Current and hydrographic observations from the Coastal Mixing and Optics experiment moored array, deployed from August 1996 through June 1997, are used to describe the velocity variability and evaluate the dynamics of circulation over the New England shelf on timescales ranging from a few days to several months. Subtidal (days...

High concentrations of chlorophyll are found in the California Current System over
300 km offshore, far from the productive coastal upwelling region, and between 150 and
250 m, well below the depth to which photosynthetically active solar radiation penetrates.
This exceptionally deep chlorophyll feature is formed near the coast and...
Observations from the Coastal Mixing and Optics (CMO) moored array (deployed from August 1996 through June 1997) and supplemental moored observations are used to describe near-inertial current variability over the New England shelf. Near-inertial band current variance comprises 10–20% of the total observed current variance, and has episodic peak speeds...
Observations from the Coastal Mixing and Optics experiment moored array, deployed from August 1996 through June 1997, are used to describe barotropic and baroclinic tidal variability over the New England shelf. The dominant M₂ tidal elevations decrease toward the northeast to a minimum over the Nantucket shoals (about 34 cm),...

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 of 50 days before the subsurface
upwelled water penetrated...
