IMOS - Deep Water Moorings - Southern Ocean Time Series (SOTS) Sub-Facility

南大洋时间序列分设施提供南极次沃茨的高时间分辨率观测。 观测范围广泛，包括测量多个深水系泊设施的物理、化学和海洋地球化学参数。 重点是上层海洋性质的年际变化及其对与深海交换的影响。 所提供的时间序列使人们能够调查海洋物理和化学、气候变化、碳循环和海洋生产力的生物地球化学控制等问题。 这些系泊设施提供了具有成本效益的观测，并克服了该区域船只稀少的问题。 <br /> <br /> SOTS位于塔斯马尼亚西南的亚南极区（SAZ），靠近47S，142E。SOTS观测结果来自<br /> 1)一种深海沉积物捕集器系泊装置，用于收集下沉颗粒以量化碳传输。 这一系泊设施还提供海流计测量和深海CTD，以测量ARGO剖面浮标测量深度以下的热含量。<br /> 2)用于测量海洋上层碳循环和浮游植物生产力过程的脉冲地球化学系泊，包括溶解气体（O2、N2）和生物光学特性的传感器测量。 该系泊系统还收集水样，用于测量溶解碳和营养物，以及浮游植物显微鉴定。仪器于2016年移至FluxPulse系泊，然后移至SOFS系泊（下图）。<br /> 3)安装在附近的南大洋通量站海气通量系泊处（并由海气通量站子设施管理）的其他生物地球化学传感器（CO2、O2、生物光学和生物声学装置）。2016年，仪器被短暂地转移到FluxPulse系泊。

The Southern Ocean Time Series (SOTS) sub-facility provides high temporal resolution observations in sub-Antarctic waters. Observations are broad and include measurements of physical, chemical and biogeochemical parameters from multiple deep-water moorings. The emphasis is on inter-annual variations of upper ocean properties and their influence on exchange with the deep ocean. The time-series provided permit investigation into issues of ocean physics and chemistry, climate change, carbon cycling and biogeochemical controls on marine productivity. These moorings provide cost-effective observations and overcome the infrequent availability of ships in the region. <br /> <br /> The SOTS site is located in the sub-Antarctic Zone (SAZ), southwest of Tasmania, near 47S, 142E. SOTS observations are made from<br /> 1) a deep ocean sediment trap mooring, used to collect sinking particles to quantify carbon transports. This mooring also provides current meter measurements and a deep ocean CTD to measure heat contents below the depth of ARGO profiling float measurements.<br /> 2) the Pulse biogeochemistry mooring, used to measure upper ocean carbon cycle and phytoplankton productivity processes included sensor measurements of dissolved gases (O2, N2) and bio-optical properties. This mooring also collects water samples for measures of dissolved carbon and nutrients, and phytoplankton microscopic identification. Instrumentation was moved to the FluxPulse mooring in 2016, and then to the SOFS mooring (below).<br /> 3) additional biogeochemical sensors (CO2, O2, bio-optical, and bio-acoustic devices) mounted on the nearby Southern Ocean Flux Station air-sea flux mooring (and managed by the Air-Sea Flux Stations sub-facility). Instrumentation was briefly moved to the FluxPulse mooring in 2016.
