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.

Maps of total zooplankton biomass (dry weight) from stepped oblique bottom to surface plankton tows from Albatross Bay. Biomass estimates from two mesh sizes. These maps have been produced by CSIRO for the National Oceans Office, as part of an ongoing commitment to natural resource planning and management through the 'National Marine Bioregionalisation' project.

This dataset is a digitised version of an updated map of phytoplankton bioregions around Australia prepared by Dr Gustaaf Hallegraeff, of the University of Tasmania for the National Oceans Office, as part of the 'National Marine Bioregionalisation' project. It is an updated version of the map previously published Jeffrey & Hallegraeff in 1991 and is based on the original data which was collected by plankton nets and water bottle sampling, using light and electron microscopy for species identification, augmented by additional phytoplankton data collected in the period 1990-2004.

This map shows phytoplankton abundance in Albatross Bay. The biomass and species composition of tropical phytoplankton in Albatross Bay, Gulf of Carpentaria, northern Australia, were examined monthly for six years between March 1986 and April 1992. Phytoplankton taxonomic groups were identified to genus level, and described as dominant, common or rare. This map has been produced by CSIRO for the National Oceans Office, as part of an ongoing commitment to natural resource planning and management through the 'National Marine Bioregionalisation' project.

Maps showing prawn larval distribution in Albatross Bay, Gulf of Carpentaria, northern Australia for both the wet and dry seasons. Prawn larval density was recorded from stepped oblique bottom to surface plankton tows in Albatross Bay. Monthly cruises were carried out between March 1986 and April 1992, at twenty-one stations in Albatross Bay, Gulf of Carpentaria. Prawn larval densities were measured and salinity-temperature profiles taken. These maps have been produced by CSIRO for the National Oceans Office, as part of an ongoing commitment to natural resource planning and management through the 'National Marine Bioregionalisation' project.

his map shows C14 primary productivity incubations at two stations over seven cruises in Albatross Bay during both the wet and dry seasons. Between February 1988 and February 1992 the FRV Jacqueline D completed nine cruises, seven in summer, two in winter, in Albatross Bay in the north-east Gulf of Carpentaria. Two stations, one 10m deep, the other at 25m, were sampled. Mean chlorophyll levels and primary productivity in the water column were measured.
