The Biological Investigations of Marine Antarctic Systems and Stocks (BIOMASS) Data Set

The Biological Investigations of Marine Antarctic Systems and Stocks (BIOMASS) Data Set has been created as part of the BIOMASS Programme directed towards deeper understanding of the ecology of the Southern Ocean, with emphasis on krill (Euphausia superba). Data were collected during 34 cruises through a collaboration by 12 countries during three field experiments. These were: the First International BIOMASS Experiment (FIBEX) from November 1980 to April 1981, the Second International BIOMASS Experiment (SIBEX), Part 1 from October 1983 to May 1984 and Part 2 from November 1984 to April 1985. Data were collected on krill distribution from acoustic surveys and krill population structure from net-hauls. Supporting data from ichthyoplankton net-hauls, oceanographic stations (temperature, salinity, nutrients and chlorophyll-a) and observations of sea-birds at sea were also collected. The BIOMASS Data Set is composed of 43 data files, extracted from the BIOMASS Oracle relational database created by the BIOMASS Data Centre that collated and standardised the data. The validation and correction of the data were carried out during data analysis workshops by the BIOMASS Programme scientists who collected the data. The majority of the BIOMASS data have been utilized during BIOMASS workshops. However, some have not been used and must be regarded as unvalidated. The documentation accompanying the BIOMASS data set lists the known problems and validation status of the data. Funding: The BIOMASS Data Set has been generated by the BIOMASS Data Centre funded by the British Antarctic Survey. Main sponsors of the BIOMASS Programme were the Scientific Committee on Antarctic Research (SCAR) and the Scientific Committee on Oceanic Research (SCOR) in collaboration with the International Association for Biological Oceanography and the Advisory Committee on Marine Resources Research of the Food and Agriculture Organization of the UN.

南极海洋系统与生物资源生物调查（BIOMASS）数据集是BIOMASS计划的一部分，旨在深入理解南大洋生态系统，重点研究磷虾（Euphausia superba）。该数据集通过12个国家合作开展的34次航行收集，涵盖三次野外实验：1980年11月至1981年4月的第一次国际BIOMASS实验（FIBEX）、1983年10月至1984年5月的第二次国际BIOMASS实验（SIBEX）第一部分，以及1984年11月至1985年4月的第二部分。数据集包含声学调查获取的磷虾分布数据、拖网采样得到的磷虾种群结构数据，以及辅助数据——鱼类浮游生物拖网采样数据、海洋学站点数据（温度、盐度、营养盐和叶绿素a）和海上海鸟观测数据。该数据集由43个数据文件组成，提取自BIOMASS数据中心创建的BIOMASS Oracle关系型数据库，该数据库对原始数据进行了整理和标准化。数据的验证与校正由收集数据的BIOMASS计划科学家在数据分析研讨会上完成。大部分BIOMASS数据已在研讨会上使用，但部分数据未被使用，需视为未经验证。随附文档列出了已知问题及各数据的验证状态。资助信息：该数据集由英国南极调查局资助的BIOMASS数据中心生成。BIOMASS计划的主要赞助方包括南极研究科学委员会（SCAR）和海洋研究科学委员会（SCOR），并与国际生物海洋学协会及联合国粮食及农业组织（FAO）海洋资源研究咨询委员会合作。
