Brief description
Zooplankton biomass data have been collected in Australian waters since the 1930s, yet most datasets have been unavailable to the research community. We have searched archives, contacted researchers, and scanned the primary and grey literature to collate this dataset (49067 records) of marine zooplankton biomass from waters around Australia, within the geographical extents of 0-60S, 110-160E. Many of these are small-scale datasets , but when combined, they provide over >85 years of large-scale zooplankton community biomass data for Australian waters from 1932 to the present.The data have been standardised, erroneous data removed, and all metadata included. The Australian Zooplankton Biomass Database will be valuable for global change studies, research assessing trophic linkages, and for initialising and assessing biogeochemical and ecosystem models of lower trophic levels.
A snapshot of the Australian Zooplankton Biomass Database at the time of this publication has been assigned a DOI and will be maintained in perpetuity by the Australian Ocean Data Network (AODN). The ongoing version of this database will be freely available through the AODN Portal (http://portal.aodn.org.au/) in the near future.
This metadata record was based on the following CSIRO metadata record: http://www.marlin.csiro.au/geonetwork/srv/eng/search?uuid=c3c9663f-50ba-41c9-b1ac-b5a9b7e9d4f7.

ATTRIBUTE STATEMENT: Field information for IMOS_ABD_DATA: RECORD_ID - Unique record identifier (Primary key) PROJECT_ID - Unique Project Identifier SAMPLE_ID - Sample identifier (Unique within a project) LONGITUDE - Sample Longitude (Decimal degrees, WGS84) LATITUDE - Sample Latitude (Decimal degrees, WGS84) SAMPLE_DATE_UTC - Sample Collection Date (UTC time) SAMPLE_TIME_UTC - Sample Collection Time (UTC time) SAMPLE_DATE_LOCAL - Sample Collection Date (Local time) SAMPLE_TIME_LOCAL - Sample Collection Time (Local time) SAMPLE_YEAR - Sample Year SAMPLE_MONTH - Sample Month SAMPLE_DAY - Sample Day DAY_NIGHT - Time of sampling if known ('day','night') [See Note 1] MIN_DEPTH - Minimum (Shallow) Sampling Depth ('0' indicates surface, '-999' indicates unknown) MAX_DEPTH - Maximum (Deep) Sampling Depth ('-999' indicates unknown) BIOMASS - Biomass Value (Note: units are specified separately and are not standardised) BIOMASS_UNITS - Biomass Units BIOMASS_METHOD - Method used to calculate biomass C_UGL - Standardised Biomass Value (Units: µg Carbon per litre) ('-999' indicates unknown) REPLICATE - Replicate Number (if known) TOW_TYPE - Type of tow used – tow direction (direction of net tow) NET_MESH_SIZE - Size of Mesh used (Units: µm) NET_ID - The numerical code for the particular net used, indicating type of sampling net used NET_TYPE - Type of sampling net (as specified in project dataset or Project citation) BOTTOM_DEPTH_MEASURED - Bathymetry depths (Units: metres) ('-999' indicates unknown) BOTTOM_DEPTH_ETOPO - Bathymetry depths (Units: metres) ('-999' indicates unknown) [See Note 2] Note 1: 1. Day and night were determined based on the local time of the sample using the crepuscule function in the maptools package in R. If time of sampling was not available but the Project recorded whether sample collection occurred in daylight or night this is recorded instead. Day or night was calculated for each record where a time of collection existed. There are some projects which had no time of collection recorded, but did note whether the sample was collected in day or night. In these instances the time portion of the date field will read 00:00 (HH:MM). Due to the timestamp used in the database, data records without a time will read 00:00 but do not have a day/night allocation. Note 2: The bathymetry depths provided in the dataset for each sample as BOTTOM_DEPTH_ETOPO were taken from the ETOPO1 bathymetry and topography database hosted by the NOAA using the Marmap package in R.
