Description
Regular glider surveys are conducted in the Ligurian Sea (North Western Mediterranean), between Nice and the DYFAMED sampling point. Between February and June 2021, i.e. during the spring bloom, the glider was equipped with an Underwater Vision Profiler: an intelligent camera system that records and process images, yielding images of all objects larger than ~600µm in Equivalent Spherical Diameter. These objects where then taxinomically assigned.

Data Records
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 7,464 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

| Purpose | The dataset contains occurrences of objects collected along the Yos of the glider, between 0 and ~600m depth. It focuses on the back transects (offshore towards inshore), which were limited to 300m depth and achieved finer horizontal resolution. The taxonomic identifications were performed using a combination of machine learning and human verificaton, using the software Morphocluster (to classify images in bulk, most often of marine snow) and EcoTaxa (to classify individual plankton images). |
