Results and Discussion
The Equatorial Subsurface Circulation
On April 14, 2017, the EUC was located between 2.2° S and 2.4° N. It is likely that
at the equator, the subsurface current rose to the surface in a band limited at both
sides by 1.5° latitudes (Fig. 1). High eastward velocities reaching 80 cm/s at a level
Fig. 1 The Lomonosov EUC on April 14, 2017. Section of zonal velocity across the equator at
33° W based on the shipboard sADCP data. The pink tones are related to the eastward velocities
and the blue tones are related to the westward velocities
Fig. 2 Sections of the zonal velocity, temperature, salinity, and potential density anomaly down
to a depth of 500 m over the equatorial section on April 14, 2017. The zonal velocity was averaged
over the entire run time of the casts. These sections illustrate vertical inhomogeneity of the
thermohaline structure and velocity field
