This dataset illustrates the distributional data of bryozoan species, belonging to the Classes of Stenolaemata and Gymnolaemata, collected in the Ross Sea and the Magellan Strait. The collection is curated at the Italian National Antarctic Museum (MNA, section of Genoa) and it includes a total of 311 specimens corresponding to 282 MNA vouchers and belonging to 127 morphospecies. Out of these, 100 were classified to species level and 27 to genus level, representing 3 orders and 34 families. The distributional data of Bryozoa came from different research expeditions, conducted between 1988 and 2014, and include 75 sampling stations, located between 18 and 711 metres of depth.

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). This dataset provides occurrence information for Amphipoda specimens spanning 25 years of scientific research and dating back to 1995. 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.
