Distributional records of Ross Sea (Antarctica) planktonic Copepoda from bibliographic data and samples curated at the Italian National Antarctic Museum (MNA)

This dataset gathers distributional data on planktonic copepods (Crustacea, Copepoda) collected in the framework of the III, V and X Expeditions of the Italian National Antarctic Program (PNRA) held in the western Ross Sea from 1987 to 1995. Sampling was conducted with BIONESS and WP2 net in 94 different sampling stations, mainly distributed in the Terra Nova Bay area, at the depth of 0-1000 meters. In terms of spatial coverage, this dataset covers 6027 distributional records that are also reported in terms of original abundance data (ind/m3) to allow a possible modelization of species distributions thanks to the availability of environmental variables that were collected together with the biological samples. The total of distributional records here reported has two different origins: 5306 are represented by bibliographic records obtained by digitizing the original data reports, whereas 721 correspond to physical museum vouchers, now curated by the Italian National Antarctic Museum (MNA, Section of Genoa). This group of museum samples comprises 8225 individual specimens, that were identified to the lowest possible taxonomic level. They belong to 4 orders, 25 families, 52 genera and 82 species, out of which 17 could be only determined at the genus level.

本数据集汇聚了意大利国家南极计划（PNRA）第三、五和十次探险期间在罗斯海西部收集的浮游桡足类（甲壳动物门，桡足纲）的分布数据。采样工作在94个不同采样站进行，主要分布在特诺瓦湾区域，水深范围在0-1000米之间。就空间覆盖而言，该数据集涵盖了6027条分布记录，并报告了原始丰度数据（个体/立方米），以便利用收集的生物样本的同时获取的环境变量，对物种分布进行可能的建模。所报告的分布记录总数源于两个不同的来源：5306条由数字化原始数据报告获得的文献记录，而721条则对应于由意大利国家南极博物馆（MNA，热那亚分部）管理的实体博物馆凭证。这组博物馆样本包含8225个个体标本，已鉴定至最低可能的分类级别。它们隶属于4个目、25个科、52个属和82个种，其中17个只能鉴定至属级。
