Tides were eliminated from the ADCP observations using a Lanczos filter with a cut-off frequency of 24 hours, leaving only the dynamic structure of the currents due to surface wind stress, bottom friction, and geostrophic forcing. In this work, only the mean currents measured during June and July 2018 were shown (Figure \ref{162479}).

Satellite data: 

To depict the regional distribution of the sea surface temperature, ocean currents, and winds during July 2018, the following remotely sensed data was employed:

(a) Optimum Interpolation Sea Surface Temperature (OISST)

The NOAA 1/4° daily Optimum Interpolation Sea Surface Temperature (or daily OISST) is an analysis constructed by combining observations from different platforms (satellites, ships, buoys) on a regular global grid. A spatially complete SST map is produced by interpolating to fill in gaps. The methodology includes bias adjustment of satellite and ship observations (referenced to buoys) to compensate for platform differences and sensor biases \citep{AnImprovedInSituandSatelliteSSTAnalysisforClimate}. These data was provided by the NOAA/OAR/ESRL PSD, Boulder, Colorado, USA, from their Web site at https://www.esrl.noaa.gov/psd/.
