Dataset type
This dataset that contains primary occurrence data for species.
Description
The dataset was collected through systematic at-sea surveys following the standardized 'European Seabirds at Sea' protocol. These surveys were conducted as part of the LIFE Artina project over a two-year period, from May 2019 to May 2021.
Geographic Description
The sea transects were carried out within a nine nautical mile radius starting from the border of the Nature Park Lastovo Islands. This border is identical with the one of the Natura 2000 site 'SPA Lastovsko otočje'.
Methods
The field data, initially digitized in Excel, was subsequently imported into R for further processing. In the original dataset, some species were identified more broadly, such as "Larus/Ichthyaetus spec." or "Apus spec." In these instances, the original values were retained in the "verbatimIdentification" column. To provide further taxonomic context, the first general taxonomic rank for each case was identified and included in the database, and all absence records are recorded as class Aves. Additionally, supplementary details—such as distance from the ship, flight direction, cloud cover, sea state, and visibility—were added as measurementOrFact entries.
Due to the deviation from the ESAS protocol and in order to keep the "true" sequence of records being taken (otherwise the NO poskeys are thrown at the end) the occurrenceID column was constructed as "record_sequence-year-transect-poskey".
