Impacts of deglaciation on benthic marine ecosystems in Antarctica (ICEBERGS): JR19002 data

The joint UK (NERC) and Chile (CONICYT) ICEBERGS project investigated the physical processes and feedbacks implicated in rapid climate-induced warming deglaciation of three west Antarctic Peninsula tidewater glacier systems, and the impacts of this deglaciation on benthic communities in the adjacent fjords between 2017 and 2020. The project involved three research cruises on the RRS James Clark Ross, JR17001 (ICEBERGS1, November-December 2017), JR18003 (ICEBERGS2, December 2018-January 2019) and JR19002 (ICEBERGS3, January-February 2020). The data from JR19002 are compiled here. The project focused on three sites, Marian Cove (King George Island), Börgen Bay (Anvers Island) and Sheldon Cove (Adelaide Island). Multidisciplinary deployments characterised each cruise, involving: CTD, multi-beam swath bathymetry, TOPAS, water sampling (salinity, oxygen isotopes), LADCP, VMADCP, EK80, Hamon grab, multicore, shelf underwater camera system (SUCS), Agassiz trawl and N70 plankton nets.

由英国（NERC，Natural Environment Research Council）与智利（CONICYT，Comisión Nacional de Investigación Científica y Tecnológica）联合实施的ICEBERGS项目，于2017年至2020年间开展研究，旨在探明南极半岛西部三处潮汐冰川系统因气候快速变暖引发的冰消退过程及其反馈机制，同时解析该冰消退过程对邻近峡湾底栖生物群落的影响。本项目依托RRS詹姆斯·克拉克·罗斯号（RRS James Clark Ross）执行了三次科考航次，分别为JR17001（ICEBERGS1，2017年11月—2017年12月）、JR18003（ICEBERGS2，2018年12月—2019年1月）与JR19002（ICEBERGS3，2020年1月—2020年2月）。本次数据集收录了JR19002航次的采集数据。项目的研究站位共三处，分别为乔治王岛马里亚纳湾、安弗斯岛博尔根湾以及阿德莱德岛谢尔顿湾。每次航次均采用多学科集成探测方案，搭载的观测设备与采样手段包括：CTD（温盐深剖面仪）、多波束条带测深系统、TOPAS浅地层剖面仪、水体采样（盐度、氧同位素检测）、LADCP、VMADCP、EK80声学系统、Hamon采泥器、多管取样器、陆架水下摄像系统（SUCS）、Agassiz拖网以及N70型浮游生物网。
