Antarctic and SubAntarctic Ophiuroidea - MNA (Section of Genoa)
-
Isopoda Latreille, 1816 is an order that consists of a vast number of taxa, living and thriving in land, sea, fresh- and groundwater. Isopods in the Southern Ocean are highly speciose and well-represented from the shelf to deep-sea zones. Biogeographical data regarding Ross Sea isopods are presented here, examining the National Antarctic Museum (MNA) Genoa section samples belonging to 15 Antarctic Expeditions. A total of 279 MNA samples were identified, resulting in 53 accepted species distributed in 24 families and 48 genera. From this identification, 15 species are considered new records for the Ross Sea area. GBIF and OBIS (Ocean Biodiversity Information System) (https://obis.org) databases, and bibliographic research were used as validation to the eventually new records for the Ross Sea area. This dataset describes the abundance and distribution of Isopoda of the 15 antarctic campaigns: PNRA Expedition Xth (1994/95), XIth (1995/96), XIIIth (1997/98), XIVth (1998/99), XVIIth (2001/02), XIXth (2003/04), XXVth (2009/10), XXVIIth (2011/12), XXVIIIth (2012/13), XXIXth (2013/14), XXXIIth (2016/17), XXXIVth (2018/19), and NSF (National Science Foundation) "Icefish04", and BAS (British Antarctic Survey) Expedition JR15005 "SO-AntEco" and JR18003 "ICEBERGS2". at Southern Ocean between 23 January 1995 and 05 December 2018.

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.
