NORFANZ Biological Survey, Tasman Sea, Australia - New Zealand 2003

Biological survey data (species IDs and catch compositions) collected during the NORFANZ voyage on the Norfolk Ridge and Lord Howe Rise in the Tasman Sea between Australia and New Zealand, in May-June 2003. The NORFANZ voyage was a collaboration between multiple Australian and New Zealand agencies including CSIRO, Australian museums and NIWA. Fourteen seamount and slope sites were sampled, 10 on the Norfolk Ridge and 4 on the Lord Howe Rise. A total of 168 operations were completed, including 144 trawl-sled-dredge shots, in depths ranging from less than 100 m to over 2000 m. Gear types included bottom trawls, midwater trawl, beam trawl, epibenthic sleds, and rock and pipe dredges. The dataset contains records of 1,622 macroinvertebrate species or provisional species units in 15 phyla, and 582 fish species in 122 families, and is expected to include a significant percentage of species new to science. Accompanying these survey data are photographs and, in some cases, voucher specimens which are held in institutions in Australia and New Zealand.
This data has been republished (2022-09-05 with additional details of each occurrence where they can be one of three types: catch composition (counts per taxa and optional aggregated weights by trawl event), catch measurements (length and/or weight) of individual taxa and/or catch specimens and their stored location. The occurrence type is recorded in occurrenceremarks.

本数据集为2003年5至6月期间，在澳大利亚与新西兰之间塔斯曼海的诺福克海脊（Norfolk Ridge）与豪勋爵海隆（Lord Howe Rise）开展的NORFANZ科考航次中采集的生物调查数据，包含物种标识与渔获组成信息。NORFANZ科考航次由澳新两国多家科研机构联合实施，合作单位包括澳大利亚联邦科学与工业研究组织（CSIRO）、澳大利亚各公立博物馆以及新西兰国家水与大气研究所（NIWA）。本次科考共布设14个海山与陆坡采样点位，其中诺福克海脊10个、豪勋爵海隆4个。累计完成168次采样作业，含144次拖网、底栖雪橇与挖泥船采样站位，作业水深范围为不足100米至2000米以上。所用采样设备涵盖底拖网、中层拖网、桁杆拖网、底栖生物雪橇以及岩石与管道挖泥器。本数据集共记录了15个门类下的1622个大型无脊椎动物物种或暂定物种单元，以及122个科下的582种鱼类，其中相当比例的物种预计为科学界首次记录的新物种。随本次调查数据同步发布的还有影像资料，部分采样还留存了凭证标本，这些标本均保存于澳新两国的相关科研机构中。
该数据集于2022年9月5日完成重新发布，补充了各采样记录的详细信息。采样记录可分为三类：渔获组成（按分类单元统计的个体数量及可选的拖网事件总重量）、单个分类单元的渔获测量数据（体长和/或体重）以及渔获标本及其存储位置。采样记录的类型在occurrenceremarks字段中予以标注。
