Fisheries acoustic data, whale and bird data from two transits from the Falkland Islands to Tristan da Cunha during March 2018 (RRS James Clark Ross) and March 2019 (RRS Discovery)

The acoustic data is separated into different categories of plankton: fish, fish without swimbladders, gas bearing plankton, plankton, and total backscatter for the RRS James Clark Ross and RRS Discovery cruises. The data is for every nautical mile along the transit and separated into 19 depth bands (in one set of files) or aggregated together (in another set of files).
The whale and bird number of each species are reported for each day.

These research cruises were co-funded through partnerships between the Foreign, Commonwealth and Development Office, through the Blue Belt program run by Cefas & MMO, and UKRI through the British Antarctic Survey (BAS) National Capability - Official Development Assistance program (NE/R000107/1 and NE/T012439/1).

本数据集涵盖RRS詹姆斯·克拉克·罗斯号（RRS James Clark Ross）与RRS发现号（RRS Discovery）科考航次的声学数据，该类数据被划分为以下类别：鱼类、无鳔鱼类、含气浮游生物、浮游生物，以及总后向散射（total backscatter）。数据覆盖航次全程的每一个海里，分为两类文件集：一类按19个深度分层划分，另一类则将所有数据聚合整合。
本数据集每日均统计并报告各鲸类与鸟类物种的个体数量。
本次科考航次由多方合作联合资助：英国外交、联邦与发展事务部（Foreign, Commonwealth and Development Office）通过由环境、渔业与水产养殖科学中心（Cefas）与英国海洋管理局（MMO）运营的蓝带计划提供支持；英国研究与创新署（UKRI）则通过英国南极调查局（BAS）国家能力建设-官方发展援助项目（NE/R000107/1与NE/T012439/1）提供经费支持。
