The variability of La Guajira upwelling system, in the south-central Caribbean Sea, is strongly influenced by the intensity and location of the atmospheric Caribbean Low-Level Jet (CLLJ), a near-surface branch of the easterlies, as well as by the regional ocean circulation.

Saildrone has launched the Saildrone Surveyor, a new 72-foot uncrewed surface vehicle (USV) equipped for high-resolution mapping of the ocean seafloor.
The Surveyor carries a sophisticated array of acoustic instruments for both shallow and deep-water ocean mapping; the Kongsberg EM 304 multibeam echo sounder is capable of mapping the seafloor down to 7,000 meters below the surface. The Surveyor also carries two state-of-the-art Acoustic Doppler Current Profilers (ADCPs), the Teledyne Pinnacle 45 kHz ADCP and the Simrad EC150-3C ADCP, to measure ocean currents and understand what is in the water column. The Surveyor is also equipped with the Simrad EK80 echo sounder for fish stock assessments.
