Book Description
Current and temperature measurements are presented from instruments deployed during May of 1976 in the western Indian Ocean, between 50 deg E and 57 deg E and between 1 deg S and 5 deg N. The experiment was part of the INDEX program. Seven mooring sites were occupied. Fourteen current meters and five temperature/pressure recorders were on WHOI moorings at 4 of the sites. Two current meters and eleven temperature/pressure recorders were on MIT moorings at 3 sites. Most of resulting data records are of eight months duration. A current profiler, the White Horse, was also used, and 41 profiles were taken over a six-week period. Basic data from the current meters are presented in statistical tables and graphically as scatter plots, progressive vector plots, spectral plots and time series plots. Filtered time series are shown in composite displays. Basic White Horse data are presented as east and north current component profiles, position plots and perspective vector plots. Selected CTD data are displayed as plots of potential temperature and salinity versus pressure, and as T-S diagrams. Data from four XBT sections are displayed graphically.

Book Description
The structure of the near-bottom velocity and density fields was observed for 3 months with a fixed velocity/temperature measuring array on the Hatteras Abyssal Plain. The velocity signal was examined for structure coherent with the observed mixed layers. Velocity fluctuations above 1 cph increase in energy near the bottom, especially within bottom mixed layers. The frequency and energy of these fluctuations is consistent with the expected properties of boundary layer turbulence. The turbulence as measured by these velocity fluctuations, is modulated on tidal and inertial time scales and extends intermittently throughout the bottom mixed layer. The clockwise near inertial velocity fluctuations, presumably due to internal waves, also show structure coherent with the observed mixed layers. Their energy decreases near the top of the mixed layer with little phase change. Within the mixed layer the phase begins to lead, with the phase increasing downward. The near inertial anticlockwise velocity fluctuations show far less coherence with the mixed layer structure; higher frequency internal wave band velocity fluctuations show very little coherence with the mixed layer structure. The characteristic boundary layer velocity signal in both the high frequency and near inertial bands commonly extends throughout the mixed layer, often significantly above the estimated turbulent Ekman layer height. These observations are inconsistent with a steady turbulent Ekman layer model of the boundary layer. (Author).

Book Description
Three surveys were made during June, 1980 on the R/V Oceanographer to measure the regional hydrographic structure in the East China Sea near the mouth of the Chang Jiang (Yangtze) River. The objective of the hydrographic program was to document the spatial and temporal structure of the Chang Jiang plume over the continental shelf and characterize the river's influence on the shelf water masses. A summary of the hydrographic observations made during Cruise RP-05-0C-80 on the R/V Oceanographer is presented in graphic form.
