KOMBI mooring datasets

This dataset contains all data collected from Krill Observational Mooring for Benthic Investigations (KOMBI) seafloor lander platforms. Platforms were left on the seafloor for one year at depths on the continental shelf and near the shelf break. The minimum depth of a mooring is 350m to avoid collision with icebergs and the maximum depth is 1500m. Their dimensions are 1145 x 1145 x 1300 mm. Moorings are typically deployed in summer months from vessels. Active acoustic (ADCP and echosounder) data, passive acoustic data, CTD data and video camera footage are available from various instruments installed on the mooring. Data is collected at varying intervals depending on the instrument. Moorings sit on the seafloor and have been positioned at various sites near the continental slope off Mawson station, East Antarctica. Data collection began in 2021 and is ongoing.本数据集收录了来自底栖生物调查磷虾观测锚系（Krill Observational Mooring for Benthic Investigations, KOMBI）海底着陆器平台采集的全部数据。该类着陆器平台将被布放于大陆架及陆架坡折带附近的海底，布放时长为一年。单锚系的最小布放深度为350米，以规避与冰山碰撞的风险，最大布放深度为1500米，外形尺寸为1145×1145×1300毫米。锚系平台通常于夏季由科考船完成布放。 锚系搭载的多款仪器可采集主动声学数据（含声学多普勒海流剖面仪（ADCP）与回声测深仪数据）、被动声学数据、温盐深仪（CTD）数据以及摄像机影像资料。 不同仪器的采样间隔各不相同。锚系固定于海底，布放点位均位于南极东部莫森站周边的大陆坡海域。 数据采集工作始于2021年，目前仍在持续进行中。
