Deep-Sea Coral and Sponge Community Data from the Corner Rise Seamounts (North Atlantic)

This dataset contains deep-sea coral and sponge community data collected from the Corner Rise Seamounts (CRS) in the North Atlantic Ocean using remotely operated vehicle (ROV) surveys (OER NOAA Cruise 2104, 2021). The data include taxonomic identifications, abundance estimates, depth information, and spatial metadata derived from annotated video transects. These data were used to examine community structure, depth-related zonation, and the occurrence of Vulnerable Marine Ecosystem (VME) indicator taxa on the CRS. The dataset supports analyses of beta diversity, assemblage clustering, and the identification of high-density coral and sponge habitats. All scripts used for data processing, analysis, and figure generation are openly available via the associated GitHub repository: https://github.com/lara-maleen/Corner_Rise. This dataset is intended to support transparency, reproducibility, and future comparative studies of deep-sea benthic ecosystems and seamount biodiversity. These data were used in “Hotspots Beyond Borders: Quantitative Assessment of Vulnerable Marine Ecosystems on the Corner Rise Seamounts with Implications for Conservation Planning” by Lara Maleen Beckmann, Lova Eveborn, Ellen Kenchington, and Rhian G. Waller, currently under review in Frontiers in Marine Science.本数据集包含2021年美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）海洋探索与研究办公室（Office of Ocean Exploration and Research, OER）航次2104中，依托遥控水下机器人（Remotely Operated Vehicle, ROV）调查采集自北大西洋科纳隆起海山（Corner Rise Seamounts, CRS）的深海珊瑚与海绵群落数据。数据涵盖基于标注视频样带得到的分类鉴定结果、丰度估算值、深度信息及空间元数据。 这些数据被用于探究科纳隆起海山的群落结构、深度相关分区特征，以及脆弱海洋生态系统（Vulnerable Marine Ecosystem, VME）指示类群的出现情况。本数据集可支撑β多样性、群落聚类分析及高密度珊瑚与海绵栖息地的识别研究。 所有用于数据处理、分析及图表生成的脚本均可通过关联的GitHub开源仓库公开获取：https://github.com/lara-maleen/Corner_Rise。 本数据集旨在提升深海底栖生态系统与海山生物多样性研究的透明度、可重复性，并为后续对比研究提供支撑。 上述数据已被用于劳拉·马琳·贝克曼（Lara Maleen Beckmann）、洛瓦·伊夫伯恩（Lova Eveborn）、艾伦·肯奇顿（Ellen Kenchington）与赖恩·G.沃勒（Rhian G. Waller）合著的《跨界热点：科纳隆起海山脆弱海洋生态系统的定量评估及其对保护规划的启示》一文，该文目前正在《海洋科学前沿》（Frontiers in Marine Science）审稿中。
