Nella Dan: FIBEX Cruise - Zooplankton data

This dataset contains results from the First International BIOMASS Experiment (FIBEX) cruise of the Nella Dan. It is the first cruise in a series of six designed to assess the distribution and abundance of krill, Euphausia superba.The FIBEX was an international programme co-ordinating the activities of 12 ships from 11 nations in the Southern Atlantic and Indian Oceans. Australia was responsible for surveying an area of the southern Indian Ocean south of 60 degrees and between 60 degrees and 90 degrees east longitude. Surveys of krill and other zooplankton were taken off Antarctica in the Australian sector (Mawson to Davis region) and Prydz Bay in January and March 1981. Species identity and abundance data were obtained. The major species investigated were Euphausia superba, Euphausia frigidia, Euphausia crystallorophias and Thysanoessa marcuria. Other pteropods and cephalopods were also studied.Physical and chemical oceanography data and phytoplankton samples were also obtained, as well as results from hydroacoustic surveys of krill biomass.Several files are available for download at the provided URL. They include excel spreadsheets on summarised data, catch composition data and station lists. Furthermore a pdf document of the report produced from the cruise is also available for download.The fields in this dataset are:DateTime (GMT)Type of TrawlSpeciesWeightNumberLatitudeLongitudeHaul NumberTowing Speed (knots)Water Depth (metres)Sea TemperatureTarget LevelsNet Open TimeNet Close TimeIceStation NumberFlowmeter ReadingTowed Distance (nautical miles)Catch Weight (grams)Fishing Start TimeFishing End TimeTrajectoryDepth Range TopDepth Range BottomCommentsThese data are also available via the biodiversity database at the provided URL. 61 taxa and 1,115 observations are present in the biodiversity database collection.

本数据集收录了“内拉丹号”（Nella Dan）首次国际生物量实验（First International BIOMASS Experiment，以下简称FIBEX）航次的相关成果。该航次是旨在评估南极磷虾（Euphausia superba）分布与丰度的6个系列航次中的首个项目。
FIBEX是一项国际合作计划，协调了来自11个国家的12艘船只在南大西洋与印度洋开展作业。其中，澳大利亚负责勘测南纬60°以南、东经60°至90°的南印度洋海域。1981年1月至3月，研究团队在澳大利亚管辖的南极海域（莫森至戴维斯区域）及普里兹湾开展南极磷虾与其他浮游动物的调查，获取了物种鉴定与丰度数据。
本次调查的主要研究物种包括南极磷虾（Euphausia superba）、冷磷虾（Euphausia frigidia）、冰磷虾（Euphausia crystallorophias）以及Thysanoessa marcuria。此外翼足类与头足类也被纳入研究范畴。
研究团队同时获取了物理海洋学与化学海洋学数据、浮游植物样本，以及南极磷虾生物量的水声调查结果。
