Dynamic topography of the sea surface in the equatorial Atlantic

From historic meridional sections of the central equatorial Atlantic it is shown that the dynamic sea surface topography varies extensively during the year…

Response of the western equatorial Atlantic Ocean to an annual wind cycle

From the Global Weather Experiment in 1979, four one-year data records are juxtaposed which simultaneously describe the wind stress, thermocline depth, surface current and transport of the Equatorial Undercurrent in the western equatorial Atlantic…

A towing system for a sensing package: Experiences and plans

The development of a technique for towing standard oceanographic sensors (pressure, temperature, conductivity, and sound velocity) at intermediate depths of less than 1000 m is described. Data show the depth characteristics of the tow and the comparative output from each of the sensors...

Zonal pressure gradient along the equatorial Atlantic

For three consecutive periods during the summer of 1974, ships of many nations made observations along the Atlantic equator as part of the GATE program [GARP (Global Atmospheric Research Program) Atlantic Tropical Experiment]. Combining these observations, it is found that the zonal pressure gradient over the central Atlantic at the surface and at 50 dbar, relative to 500 dbar, increased from 3.2 to 7.3 and 2.2 to 5.3 × 10-5 dynes/g respectively between June/July and August and then held close to the high values in September...

On the stationarity of temperature spectra at high horizontal wave numbers

Two examples of high wave number (one cycle per 5 m to one cycle per kilometer) temperature spectra from constant depth tow segments are presented. The first is from observations in the center of the main thermocline of the northwest Atlantic at a depth of about 700 m. Four independent estimates of the spectrum are statistically similar to one another. The result is continuous with previous results at lower wave numbers and compares favorably with the 1975 Garrett and Munk internal wave model prediction. The second example is from a tow through a surface mixed layer, at a depth of 26 m, in a nearby area. In contrast to the above, it describes the lack of stationarity of the near-surface spectrum; a result reminiscent of the frequency spectra observed by Sabinin
