Biogeochemical data of sinking particulate matter collected by sediment trap mooring 12-01 (2017-2018) in the South Indian Ocean

The Universität Hamburg is part of the environmental studies in the INDEX (Indian Ocean Exploration) program, which was established by the BGR (Federal Institute for Geosciences and Natural Resources), Hanover. The INDEX license area is located in the oligotrophic subtropical gyre of the South Indian Ocean. Sinking particulate matter samples were collected by sediment trap mooring 12-01 to measure vertical particle flux quantitatively and qualitatively. Mooring 12-01 was deployed during cruise SO259 (RV Sonne) and recovered during cruise PE446 (RV Pelagia).

汉堡大学（Universität Hamburg）参与了由汉诺威联邦地球科学与自然资源研究所（BGR, Federal Institute for Geosciences and Natural Resources）牵头设立的印度洋勘探（INDEX, Indian Ocean Exploration）计划中的环境研究项目。该INDEX许可区域地处南印度洋的贫营养亚热带环流海域。研究人员借助沉积物捕集器锚系12-01（sediment trap mooring 12-01）采集沉降颗粒物样品，以定量、定性地测定垂直颗粒通量。沉积物捕集器锚系12-01于SO259航次（“松恩”号科考船，RV Sonne）期间布放，并在PE446航次（“佩拉吉亚”号科考船，RV Pelagia）期间回收。
