Abstract:
Hydrographic measurements from a transect off northern Chile (20° S) are reported. The data were collected using a CTD SBE 9-11 mounted on a rosette. The CTD was equipped with two temperature, conductivity and oxygen sensors, a fluorometer and PAR sensors. The cruise was carried out on the R/V Cabo de Hornos between 3rd and 6th of february 2018.

Comment:
This dataset has been carefully reviewed and curated in accordance with PANGAEA's exceptionally high quality standards. However, due to discontinued communication from the authors' side, it did not receive the usual formal approval by the authors and therefore lacks final scientific validation.
