Title:The AlborEX dataset: sampling of sub-mesoscale features in the Alboran Sea
Journal:Earth System Science Data
Issue No.:11

The AlborEX (Alboran Sea Experiment) consisted of a multi-platform, multi-disciplinary experiment

carried out in the Alboran Sea (western Mediterranean Sea) between 25 and 31 May 2014. The observational

component of AlborEx aimed to sample the physical and biogeochemical properties of oceanographic features

present along an intense frontal zone, with a particular interest in the vertical motions in its vicinity. To this end,

the mission included 1 research vessel (66 profiles), 2 underwater gliders (adding up 552 profiles), 3 profiling

floats, and 25 surface drifters.

Near real-time ADCP velocities were collected nightly and during the CTD sections. All of the profiling floats

acquired temperature and conductivity profiles, while the Provor-bio float also measured oxygen and chlorophyll

a concentrations, coloured dissolved organic matter, backscattering at 700 nm, downwelling irradiance at 380,

410, and 490 nm, as well as photo-synthetically active radiation (PAR).

In the context of mesoscale and sub-mesoscale interactions, the AlborEX dataset constitutes a particularly

valuable source of information to infer mechanisms, evaluate vertical transport, and establish relationships between

the thermal and haline structures and the biogeochemical variable evolution, in a region characterised

by strong horizontal gradients provoked by the confluence of Atlantic and Mediterranean waters, thanks to its

multi-platform, multi-disciplinary nature.

The dataset presented in this paper can be used for the validation of high-resolution numerical models or

for data assimilation experiment, thanks to the various scales of processes sampled during the cruise. All the

data files that make up the dataset are available in the SOCIB data catalog at

(Pascual et al., 2018). The nutrient concentrations are available at
