Cruise 21-810 is part of the regular LifeWatch campaigns covering the Belgian Economic Exclusive Zone within the scope of the Flemish contribution to LifeWatch.eu. The dataset covers the two day cruise held from 26 to 28 October 2021 and includes all navigation, meteorological and surface hydrography parameters.
The data were not calibrated against independent measures but was quality controlled for the presence of outliers, anomalous and impossible values. Data are made available at a 1minute resolution, following the international conventions agreed for this type of data.
