Seafloor images and videos collected along OFOBS profile PS143/1_37-1 during RV POLARSTERN cruise PS143/1@en

These images and videos were acquired during the expedition PS143/1 with the German ice breaker FS POLARSTERN in June/July 2024, in the Fram Strait between Greenland and Svalbard. This data supports time-series studies at the LTER (Long-Term Ecological Research) observatory HAUSGARTEN in order to document natural and global change induced environmental variations in polar deep-water ecosystems. The images were acquired by AWIs OFOBS. Aim: Investigation of benthic habitats in the Fram Strait at a target altitude of 1.5 m. Deployment was planned to follow the regular transect at S3. The laser markers are spaced 50 cm apart.

本批次图像与视频采集于2024年6-7月德国破冰船FS POLARSTERN执行的PS143/1科考航次，作业海域为格陵兰与斯瓦尔巴群岛之间的弗拉姆海峡（Fram Strait）。本数据集服务于长期生态研究（Long-Term Ecological Research, LTER）观测站HAUSGARTEN的时间序列研究，用于记录极地深海生态系统中自然演化与全球变化驱动的环境变异。本批图像由阿尔弗雷德·魏格纳研究所（AWI）的OFOBS系统采集。研究目标为在1.5米的目标拍摄高度下，对弗拉姆海峡的底栖生境开展调查。科考部署计划遵循S3站位的常规断面航线。激光标记点的间距为50厘米。
