Distribution records of Amphipoda based on the collection stored at the Italian National Antarctic Museum (MNA) is an occurrence type dataset published by Italian National Antarctic Museum (MNA, Section of Genoa).
The distributional information provided here represents the specimens stored at the Italian National Antarctic Museum (MNA) belonging to the order Amphipoda and acquired in the context of 23 different research projects that took place during 16 scientific polar expeditions conducted in Antarctica. It represents an additional resource documenting the distribution of Antarctic Amphipoda in the Southern Ocean, from the Antarctic Peninsula to the Ross Sea, focusing on the Terra Nova Bay area. This dataset reports a total of 456 distributional occurrences of Amphipoda specimens, collected during 117 different sampling events, and corresponding to 24 families, 27 genera and 34 different species. Out of the total occurrences reported, 217 are identified to the species level, 72 to the genus and 75 to the family level.

The occurrences included in this dataset were obtained in the context of a variety of research projects funded by the Italian National Antarctic Program (PNRA) and Alfred Wegener Institute (AWI). The publication of this data paper was funded by the Belgian Science Policy Office (BELSPO, contract n°FR/36/AN1/AntaBIS) in the Framework of EU-Lifewatch as a contribution to the SCAR Antarctic biodiversity portal (biodiversity.aq).
The data in this occurrence 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 456 records.
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.

|Title||Distribution records of Amphipoda based on the collection stored at the Italian National Antarctic Museum (MNA)|
|Funding||Data originated in the framework of 15 different PNRA (Italian National Antarctic Program) expeditions and one AWI (Alfred Wegener Institute) expedition, carried out from 1995 to 2019 within 23 research projects funded by the PNRA and the AWI. A list of research projects and associated funders is reported in the associated data paper. The publication of this data paper was funded by the Belgian Science Policy Office (BELSPO, contract n°FR/36/AN1/AntaBIS) in the Framework of EU-Lifewatch as a contribution the the SCAR Antarctic biodiversity portal (biodiversity.aq)|
The variety in the scientific goals between these projects, not exclusively focusing on biology or ecology, and spanning an overall temporal range of 25 years, does not allow to provide a quantitative dataset, but rather an occurrence resource for Antarctic Amphipoda, still reporting basic metadata such as geographic coordinates, depth and adopted sampling methodology. For this reason, the sampling methodology used during the execution of each different program is not always reported in detail, but only with a general definition and, eventually, with comments describing the main characteristics. Moreover, many occurrences originate from samples acquired using methodologies not commonly used to sample planktonic or benthonic arthropods (e.g. gill nets, trammel nets), and obtained as by-catch, whereas others were acquired using recently developed (or adopted), and still not commonly used devices and sampling methodologies (e.g. desalination plant’s filters, Autonomous Reef Monitoring Structures). For these occurrences, a link to a publication describing the adopted methodology is provided in the dataset.
|Study Extent||This dataset provides occurrence information for Amphipoda specimens spanning 25 years of scientific research and dating back to 1995. The diversity in the scientific goals proposed by this plethora of projects is reflected by the difference in the geographic extent of the areas investigated during each expedition. In fact, most of the occurrences reported in this dataset originate from samples acquired in the Terra Nova Bay area (between the Drygalski Ice Tongue and Cape Washington), close to “Mario Zucchelli” station where small boats and zodiacs could be deployed and where most of the Italian Scientific Polar Expeditions reported here had their geographic focus. A reduced number of occurrences originates from projects focusing on a larger geographic area of the Ross Sea, in the context of a few expeditions, which took place by adopting a larger vessel, the R/V “Italica”. In the Ross Sea, most of the sampling stations are located along the coastline of the Victoria Land, reaching as far north as Cape Adare, while others reach the easternmost area of the Ross sea. On the Antarctic Peninsula, most of the sampling stations are located close to the Bransfield Strait, and only one located near the Drake passage.|
|Quality Control||All records were validated. Coordinates were plotted on map to verify the actual geographical location corresponds to its locality. All scientific names were checked for typo and matched to the species information backbone of Worlds Register of Marine Species (http://marinespecies.org/) and LSID were assigned to each taxa as scientificNameID. Event dates are compliant to ISO 8601 standard.|
Method step description:
- As the dataset is composed of occurrences originating from a variety of expeditions and projects, the treatment and steps adopted to process each sample may differ depending on the expedition, the project and the personnel involved. However, in most of the cases, samples were usually sorted in situ and directly stored in formalin or absolute ethanol, to be identified later on by other researchers after the samples were donated to the MNA. The samples are now stored in absolute ethanol, dried or at -20°C.
- Most of the records were identified by one researcher (AJ), using original descriptions and taxonomic keys. The identification was often supported by taking pictures at the binocular and combining stack images of the analyzed specimens. The identification of many specimens, corresponding to more than 25% of the entire dataset, was aided by the application of DNA barcoding analyses, including the amplification and sequencing of the cytochrome oxidase I (COI) region, in a collaboration with the Canadian Centre for DNA Barcoding (CCDB) and uploaded to the Barcode Of Life Data System (BOLD System). The results obtained in this context will be the subject of another publication.
