Abstract:: Temperature, salinity, sigma-t and dissipation profiles from the Rapid Sampling Vertical Profiler for six transects as part of the Coastal Transition zone pilot experiment, June 1987.
Resource Type:: Technical Report

Creator:: Nash, Jonathan D., Caldwell, Douglas R., Zelman, Michael J., and Moum, James N.
Abstract:: A fast-response chromel–constantan thermocouple sensor was constructed for use on the microstructure profiler Chameleon and used for 60 ocean profiles off the coast of Oregon. The stability of the thermocouple was compared to that of an FP07 microbead thermistor, and its frequency response was compared to a high-resolution microconductivity probe....

Abstract:: During August 1986, a large cold anomaly was observed in satellite and in situ measurements near Cape Blanco at 42°N, 126°30′W off the Pacific Coast. Detailed vertical profiles of temperature, conductivity, turbulent dissipation, and horizontal currents showed 1) surface water temperature changes as large as 2 degrees in 1 kilometer...

Creator:: Moum, James N., Caldwell, Douglas R., and Paulson, Clayton A.
Abstract:: Twelve days of microstructure measurements at the equator (140°W) in November 1984 showed a surprisingly strong effect of both the daily cycle of solar heating and wind on mixing in the upper ocean. Because of limited variations in atmospheric forcing and currents during the experiment, processes in the daily mixing...

Creator:: Lien, R.-C., Caldwell, Douglas R., Gregg, M.C., and Moum, James N.
Abstract:: 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 November 4 to December 12, 1991, near the National Oceanic and...

Creator:: Chereskin, T. K., Moum, James N., Stabeno, P. J., Caldwell, Douglas R., Paulson, C. A., Regier, L. A., and Halpern, D.
Abstract:: In November-December 1984 we carried out an intensive 12-day upper ocean sampling program on the equator at 140°W as part of the Tropic Heat Experiment. From our observations we constructed hourly averaged profiles of temperature, salinity, σ₁, turbulent kinetic energy dissipation rate, and horizontal velocity. These data were used to...

Creator:: Dewey, Richard K., Moum, James N., Paulson, Clayton A., Caldwell, Douglas R., and Pierce, Stephen D.
Abstract:: Repeated microstructure transects across filaments in the coastal transition zone (CTZ) have Revealed fundamental structure and dynamics of the complicated features. The measurements allow detailed momentum and vorticity analyses and provide a possible explanations for structural asymmetry of the fronts. Observations made between July 2 and July 23, 1988, along...

Creator:: Dewey, Richard K., Moum, James N., and Caldwell, Douglas R.
Abstract:: This paper presents observations of a dynamic minifilament and summarizes the findings of three microstructure surveys across and within the meandering current structures of the Coastal Transition Zone (CTZ). An actively turbulent minifilament is discussed and possible consequences of the small-scale processes with regard to frontal dynamics are examined. Four...

Abstract:: From a comprehensive set of upper ocean measurements made during a moderate El Niño in boreal spring 1987, we reassess the role of turbulence in transporting momentum vertically at the equator. An examination of the terms in the vertically integrated zonal momentum equations indicates that on short time scales the...
