Biological data from the IPY-CAML voyage (TAN0802) by the R/V Tangaroa. The TAN0802 voyage departed from Wellington, New Zealand on Jan 26th 2008 and returned to Wellington, New Zealand, on Mar 21st 2008. The survey was concentrated mainly on the Ross Sea and the waters around Scott and the Balleny Islands. Biological data was collected using a variety of gear, including: bottom trawls, beam trawls, epibenthic sleds, Van Veen grabs, Rosette water bottle and MOCNESS tows. The voyage resulted from a announcement by the Prime Minister in 2007 for new government funding for a New Zealand Census of Antarctic Marine Life (CAML) project to support biodiversity studies in the Southern Ocean and Ross Sea Region as part of the governments Ocean Survey 20/20 (OS2020) programme and the International Polar Year (IPY) activities. The overall Project includes two phases a) data collection voyage and b) data analysis and reporting. The recognition of International Polar Year (IPY) throughout the globe from March 2007 to March 2009 has provided the impetus for a large international effort to conduct collaborative research both in Antarctica and the Arctic, spanning two summer seasons in both regions. New Zealand is participating in a range of both terrestrial and marine projects for IPY that are important, not only nationally, but also in the international science arena. The Census of Antarctic Marine Life (CAML) is a major multi-national IPY Programme that New Zealand’s project is part of. This project forms a particularly important component of the international CAML Programme, as it will not only be part of the circum-polar national surveys, but will provide an opportunity to compare fauna and ecosystems from opposite sides of the globe including the two most significant shelf areas in Antarctica-the Ross Sea and the Weddell Sea.
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 8,478 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.

No Description available
|Title||New Zealand IPY-CAML project|
|Funding||The project is a major collaboration between Land Information New Zealand (LINZ), Ministry of Fisheries, Ministry of Foreign Affairs and Trade, Antarctica New Zealand, Te Papa, the National Institute of Water and Atmospheric Research (NIWA), and New Zealand universities. The voyage also connects to New Zealand’s whole-of-government, Ocean Survey 20/20 programme, where it is one of several voyages proposed over a number of years. In addition, there is international collaboration with Italian, USA, Canadian, and Australian scientists.|
|Study Area Description||The study was the Ross Sea around the New Zealand administed Ross Dependency, Antarctica.|
|Design Description||The biological components sampled during the voyage included viruses, bacteria, plankton, benthic fauna, cephalopods, fish and top predators. Analyses to describe the biodiversity in the Ross Sea and contribute to the Census of Antarctic Marine Life Programme explored measures of endemism, species richness, complexity, taxonomic distinctness and genetic diversity throughout the region. The relationships between the biological patterns observed and different environmental gradients included the water column from surface to seabed at different bottom depths, substrate type, bottom slope, water mass, ice cover and ice-berg scour. To understand how the ecosystem functions dynamically, studies of feeding patterns was carried out across as many biological groups as possible and the information used to improve ecosystem modelling of the Ross Sea region. Understanding ecosystem function and the effects of toothfish fishing in the Ross Sea is a key requirement for fisheries management under CCAMLR. Ocean acidity and other water chemistry attributes are critical pieces of information that were collected throughout the voyage to not only characterise the hydrological setting of the region, but to also provide baseline measures for monitoring environmental change. Other potential indicators investigated for their utility in longterm ecosystem monitoring. The data collected will provide a host of other new information. For example, habitat and biological mapping will greatly improve progress on “bioregionalisation” of the area. Many hundreds of species will be taxonomically described and genetically “barcoded” to facilitate species identification in the region. The project will allow New Zealand and other international collaborators to explore concepts of evolution and species divergence in the Southern Ocean. Seamounts east of the Balleny Islands will be sampled to provide a comparison with previous surveys at the Balleny Islands and improve understanding of the role that seamounts and island outcrops play in marine biodiversity and faunal refuges in the Southern Ocean.|

For the IPY-CAML project, the Ross Sea region was subdivided into three survey areas, each of which was stratified by depth, and had a different balance of core versus additional stations to reflect the multiple objectives of the project. The core stations allowed broad-scale comparisons between areas on a regional scale. Their distribution within depth strata of each survey area also allowed comparisons to be made within each area. The additional stations were designed to support objectives that are specifically relevant to high priority objectives within a particular area. Biological data was collected using a variety of gear, including: bottom trawls, beam trawls, epibenthic sleds, Van Veen grabs, Rosette water bottle and MOCNESS tows.
|Study Extent||Biological sampling in the Ross Sea, Antarctica, during the summer (Jan-Mar) of 2008|
|Quality Control||The scientific names have been mapped to the World Register of Marine Species (WoRMS), using the online taxon match tool. All sampling locations have been plotted on a map to perform a visual check. The most important check would be to see if all sampling locations are (1) in the marine and/or brackish environment and (2) within the described sampling area.|
