This dataset comprises the phytoplankton abundance and biovolume estimates as part of a broader sampling program carried out at the Southern Ocean Time Series, a facility within the Integrated Marine Observing System (IMOS). The primary focus is sustained observing of ocean properties and processes important to climate, carbon cycling, and ocean productivity. Regular phytoplankton samples are collected at approximately 14 day intervals (exact intervals and seasonal coverage dependent on deployment length). The moorings are serviced annually, at which time the existing moorings are recovered and new moorings are deployed. Water samples from within the surface mixed-layer are collected at pre-programmed intervals using a Remote Access Sampler, in pairs about 1 hour apart. One sample in each pair is preserved for phytoplankton community composition by microscopy, and the other sample is preserved and used for accompanying chemical analysis of nutrients, total dissolved inorganic carbon (DIC) and alkalinity. Each sample is collected from within the surface mixed-layer at 32 m depth (2010 - 2017) or 5 m depth (2018-current) depending on the design of the mooring surface assembly and instrumentation. Typically a maximum of 24 samples are collected over an annual deployment cycle. The samples collected are analysed for: 1. Community composition / abundance (cells/L) 2. calculated biovolume (um3/L). Protocols for the phytoplankton time-series are described in Eriksen et al (2018), and the annual sample reports for each deployment. Data storage and access is planned to be interoperable with other national and international programs through the IMOS Infrastructure. Station metadata can be found through this resource. Data is available freely via the AODN portal: https://portal.aodn.org.au. As the taxonomic resolution of the data has changed over time, due to continual training, it is important that users refer to the change log tables included in your data download. These will provide information on the validity of the taxa, from what date we have been identifying certain taxa etc. Classification fields may be blank depending on the level to which that taxa has been identified, i.e. if only identified to family, genus and species will be blank.

This dataset comprises the current meter data collected from Devonport (Tasmania) during March-July 1992, as part of a study of ocean currents in Bass Strait in relation to potential effluent dispersal. There are 3 moorings with 3 current meters represented in this dataset. Parameters typically recorded in current meter data comprise east-west and north-south velocity components, water temperature, pressure, and salinity at a nominal depth for each current meter. The data have been processed and are archived as part of the holdings of the CMR Data Centre in Hobart.

This dataset comprises the current meter data collected from the LUCIE Dongara locality (WA coast) during September 1986-August 1987, as part of the Leeuwin Current Interdisciplinary Experiment (LUCIE). There are 10 moorings with 29 current meters represented in this dataset. Parameters typically recorded in current meter data comprise east-west and north-south velocity components, water temperature, pressure, and salinity at a nominal depth for each current meter. The data have been processed and are archived as part of the holdings of the CMR Data Centre in Hobart.

This dataset comprises the current meter data collected from a study of the South Australian Upwelling during January-February 1989. The moorings were deployed at sites to the north-west of the upwelling zone, offshore from Robe, South Australia, as indicators of shelf waves entering the region. There are 2 moorings with 2 current meters represented in this dataset. Parameters typically recorded in current meter data comprise east-west and north-south velocity components, water temperature, pressure, and salinity at a nominal depth for each current meter. The data have been processed and are archived as part of the holdings of the CMR Data Centre in Hobart.
