The MILDEX cruise of October - November 1983 was a
multiship (including FLIP) experiment involving intensive
sampling of the ocean by a variety of instruments. The RV
Wecoma operated by Oregon State University College of
Oceanography sailed from Newport, Oregon on October 21 and
returned to San Diego, California on...
The behavior of three ecosystem models is analyzed for upwelling off the Oregon coast as a function of the number of model components. The first ecosystem model includes dissolved inorganic nitrogen-phytoplankton-zooplankton (NPZ), the second (NPZD) adds detritus, and the third (NNPZD) splits the nutrients into nitrate and ammonium. The models...
Three-component (NPZ), four-component (NPZD), and five-component (NNPZD) nitrogen-based ecosystem models are compared. The fixed points of the zerodimensional systems, with no spatial variation except light attenuation by water, are determined. A linear-stability analysis shows that unstable steady solutions exist for all three models. Time-periodic solutions are found in these regions....
MILDEX, a mixed layer dynamics experiment, began
October 21, 1983 and lasted until November 16, 1983.
R.P. Flip, R.V. Wecoma and R.V. Acania rendezvoused at
34° N, 127° W to participate in joint observations of
the mixed layer and upper ocean. This report contains
data from the WAve Zone Profiler,...
In this report we describe a preliminary version of a temperature/conductivity profiler that combines the calibration accuracy of a CTD with the vertical resolution of a microstructure instrument and the ease of deployment of an XBT. We also describe the results of a test of this version on a month-long...
In a discussion of the turbulence characteristics of patches of 'microstructure' in the ocean, the hypothesis advocated by Gibson (1982), that the patches are produced by very rare but extremely powerful turbulence-generating events which usually have 'fossilized' before their observation, is contrasted with the hypothesis of a turbulence field driven...
Repeated conductivity, temperature, and depth (CTD) sections were made across the continental
margin off Peru at 5°S and 10°S between November 1981 and May 1984, i.e., before, during, and after El
Nino of 1982-1983. Coastal sea level at Paita (5°S) and Callao (12°S) began to rise in early October 1982...
Our primary purpose in developing this instrument is to measure
vertical temperature fluctuations in the ocean to the smallest scales at
which they exist. This goal dictates the basic concept of the instrument,
as C. S. Cox saw in the 1960's. Vertical temperature changes are seen
as changes with time...
