  • Inner-shelf circulation off the central Oregon Coast

    Creator:
    Kirincich, Anthony R.
    Abstract:
    Inner-shelf circulation and mechanisms of across-shelf transport of water masses were examined using seven years of observations collected by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) program, a long-term monitoring effort along the central Oregon coast. Since 1998, moored velocity and hydrographic measurements have been obtained during the...

  • Semidiurnal Baroclinic Tides on the Central Oregon Inner Shelf

    Creator:
    Suanda, Sutara H. and Barth, John A.
    Abstract:
    Semidiurnal velocity and density oscillations are examined over the mid- and inner continental shelf near Heceta Bank on the Oregon coast. Measurements from two long-term observation networks with sites on and off the submarine bank reveal that both baroclinic velocities and displacements are dominated by the first mode, with larger...

  • Subtidal inner-shelf circulation near Point Conception, California

    Creator:
    Cudaback, Cynthia N., Washburn, Libe, and Dever, Edward P.
    Abstract:
    We discuss connections between inner‐shelf and mid‐shelf circulation near Point Conception, California, as well as the wind forcing of inner‐shelf circulation. Point Conception marks the southern edge of a major upwelling zone that extends from Oregon to central California. The coastline makes a sharp eastward turn at Point Conception, and...

  • Diurnal heat balance for the northern Monterey Bay inner shelf

    Creator:
    S. H. Suanda, S. H., Barth, J. A., and Woodson, C. B.
    Abstract:
    In the summer of 2007, physical measurements including velocity from acoustic Doppler current profilers, surface gravity wave heights measured acoustically, and temperature from thermistor chain arrays were collected along- and across- the mid to inner shelf (water depths from 10–60 m) in northern Monterey Bay. The oceanic response to a...

  • Wind-driven inner-shelf circulation off central Oregon during summer

    Creator:
    Kirincich, Anthony R., Barth, John A., Grantham, Brian A., Menge, Bruce A., and Lubchenco, Jane
    Abstract:
    Velocity measurements from 17 deployments of moored acoustic Doppler current profilers obtained during four summer upwelling seasons are used to describe the crossshelf divergence of Ekman transport in the inner shelf off Oregon. For each deployment the measured surface and bottom cross-shelf transports were compared with estimates of the theoretical...

  • Wave-Driven Inner-Shelf Motions on the Oregon Coast*

    Creator:
    Kirincich, Anthony R., Lentz, Steven J., and Barth, John A.
    Abstract:
    Recent work by S. Lentz et al. documents offshore transport in the inner shelf due to a wave-driven return flow associated with the Hasselmann wave stress (the Stokes–Coriolis force). This analysis is extended using observations from the central Oregon coast to identify the wave-driven return flow present and quantify the...

  • Time-Varying Across-Shelf Ekman Transport and Vertical Eddy Viscosity on the Inner Shelf

    Creator:
    Kirincich, Anthony R. and Barth, John A.
    Abstract:
    The event-scale variability of across-shelf transport was investigated using observations made in 15 m of water on the central Oregon inner shelf. In a study area with intermittently upwelling-favorable winds and significant density stratification, hydrographic and velocity observations show rapid across-shelf movement of water masses over event time scales of...

  • Evaporative dense water formation and cross‐shelf exchange over the northwest Australian inner shelf

    Creator:
    Shearman, R. Kipp and Brink, Kenneth H.
    Abstract:
    High‐resolution surveys of oceanographic and atmospheric conditions made during the winter over the inner shelf off northwest Australia are used to examine the coastal ocean response to large outgoing heat and freshwater fluxes. Relatively cool, low‐humidity air blows off the Australian continent out over the tropical continental shelf, resulting in...

  • Tidal-band and high-frequency internal variability on the central Oregon inner shelf

    Creator:
    Suanda, Sutara H.
    Abstract:
    Analogous to ocean surface waves, waves in the ocean interior also experience steepening, breaking, and dissipation as they approach the coastline. Much less is known about this internal beach. In this work, extensive moored Acoustic Doppler Current Profiler and temperature/salinity data together with optical remote sensing are combined to describe...

    Abstract:
    In the summer of 2007, a biophysical experiment was conducted to identify physical processes that determine the delivery of invertebrate larvae and juvenile rockfish to rocky intertidal and kelp forest communities in northern Monterey Bay, California. The experiment was sponsored by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO)...
