Deployed and retrieved by the Marine National Facility (MNF) on behalf of Integrated Marine Observing System (IMOS), the Southern Ocean Time Series Observatory 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 in the sub-Antarctic Zone southwest of Tasmania. The emphasis is on seasonal and inter-annual variations of lower atmosphere and upper ocean properties and their influence on exchange with the deep ocean. The continuous time-series information allows the study 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.
