Summary

Full Title

ross_sea_mollusca_lgp

Description

Information regarding the molluscs in this dataset is based on the Rauschert dredge samples collected during the Latitudinal Gradient Program (LGP) on board the R/V “Italica” in the Ross Sea (Antarctica) in the austral summer 2004. A total of 18 epibenthic dredge deployments/samplings have been performed at four diffrent locations at depths ranging from 84 to 515m. In total 8,359 specimens have been collected belonging to 161 species. Of these, in order of abundance, 5,965 specimens were Gastropoda (accounting for 113 species), 1,323 were Bivalvia (accounting for 36 species), 949 were Aplacophora (accounting for 7 species), 74 specimens were Scaphopoda (3 species), 38 were Monoplacophora (1 species) and, finally, 10 specimens were Polyplacophora (1 species).

Study area description

This dataset lists the species that have been collected by deploying for the first time a Rauschert dredge in the Ross Sea (Rehm et al. 2006). Samples were obtained during the Austral summer 2004 in the framework of the 19th PNRA Antarctic expedition, on board the R/V “Italica”. The study area was the continental shelf along the latitudinal transect comprised between Cape Adare (~71°S) and Terra Nova Bay (~75°S). The Rauschert dredge was deployed in its ‘standard’ structure, i.e. having a mesh size of 500μm and with an opening of 0.5 m (Lörz et al, 1999). The dredge has been towed at a mean velocity of 1 knot to collect benthic samples at eighteen stations, comprised between 84 and 515m of depth. More details about sampling stations are reported in Rehm et al. (2006).

Design description

In the past decade, the Ross Sea has been the area studied by the Latitudinal Gradient Program (LGP; www.lgp.aq) which aimed at: i) understanding the complex ecosystems that exist along the Victoria Land coast; and ii) determining the effects of environmental change on these ecosystems; iii) maximising the transfer of information and ideas, by utilising joint logistic facilities. To achieve these targets, two temporally parallel research voyages took place during the Austral summer 2004: one on board the Italian RV “Italica” and one on board the RV “Tangaroa” (“BioRoss” voyage, TAN0402) organized, respectively, by NIWA (National Institute of Water and Atmospheric Research, Wellington) and PNRA (Antarctic National Research Project). The LGP contributes to the SCAR biology programme Evolution and Biodiversity in the Antarctic (EBA). The present molluscs dataset has been formatted in order to fulfil the standards required by the OBIS schema (http://iobis.org/data/schema-and-metadata) according the SCARMarBIN Data Toolkit (available at http://www.scarmarbin.be/documents/SM-FATv1.zip). The dataset was uploaded in the ANTOBIS database (the geospatial component of SCARMarBIN), and the taxonomy was matched against the Register of Antarctic Marine Species, using the Taxon Match tool (http://www.scarmarbin.be/rams.php?p=match). The dataset, therefore, meets the Darwin Core requirements and was designed around this data schema. Data from both the RV “Italica” and the RV “Tangaroa” (“BioRoss”, TAN0402) voyages were published in Schiaparelli et al. (2006). A detailed analysis of the distribution of mollusc species sampled by the Rauschert dredge is in Ghiglione et al. (submitted).

Funding

This study is part of the Project 2002/8.6 (“The coastal ecosystem of Victoria Land Coast: distribution and structure along a latitudinal gradient”) funded by the Italian National Antarctic Research Program (PNRA).
