Data Trawler - Overview of Data holdings

Acoustic Doppler Current Profiler (ADCP) data has been collected since 1987 from over 300 voyages with more than 700,000 positions yielding 15 million discrete velocity measurements. Over that period, the original processed data format has varied considerably from text files to various versions of netCDF. The Data Trawler provides a method to extract the ADCP data into one format.

CSIRO O&A Acoustic Doppler Current Profile (ADCP) Data Overview (1987 - present)

This dataset contains the processed Acoustic Doppler Current Profile (ADCP) data collected on Australia's Marine National Facility (MNF) RV Franklin, RV Southern Surveyor and RV Investigator from 2007 to present. The ADCP instrument typically operates at frequencies of 75kHz and 150khz. with respective maximum depths of 800 and 300 metres. The typical ensemble period is 5 minutes with depth bands ranging from 8 to 16 metres. The RV Investigator dataset has been QCed by the CSIRO Oceans and Atmosphere Data Acquisition and Processing group. The data can be retrieved via CSIRO O&A Data Trawler from each survey page, please see link below. The ADCP data format has evolved over time and this dataset has been sourced from about 15 data formats from csv to early adoption of netCDF formats. The data quality is likely to be varied so it is prudent to view each survey's data processing report.

CSIRO O&A CTD Data Overview (1982 - present)

The CSIRO Oceans and Atmosphere (O&A) previously CSIRO Marine and Atmospheric Research (CMAR) CTD (Conductivity Temperature Depth) dataset includes data collected since 1982 during the voyages of Australia's Marine National Facility, and of various CSIRO marine research vessels. CTD data typically consists of vertical profiles binned at 2-metre intervals. Data usually includes conductivity, temperature, depth and salinity (derived), and may also include any or all of oxygen, fluorescence, optical back scatter (OBS), pH and transmittance. Individual metadata records have been created for each research voyage. The data is held in the O&A Information & Data Centre Data Warehouse, which currently holds over 14,321 CTD station records from more than 285 voyages.

RV Investigator Radon Data - Selected Voyages (2014 onwards)

The Radon measurements are obtained from a sensor mounted on the Research Vessel RV Investigator of the Australian Marine National Facility (MNF) managed by CSIRO Oceans and Atmosphere (O&A), and processed by ANSTO's Institute for Environmental Research. The dataset includes quality-controlled data collected from 2014 onwards. The RV Investigator voyages where data was collected and processed are listed below in this record. Potential users of the dataset are encouraged to discuss any aspects of its application with the contact persons listed in the dataset “Notes” tab: we are very enthusiastic and keen to support and participate in your science!

RV Investigator ISAR/SST Sea Surface Temperature Data Overview (2014 onwards)

This record describes the ISAR/SST Sea Surface Temperature data collected on the RV Investigator Voyages from 2014 onwards. The infrared SST autonomous radiometer (ISAR) is a self-calibrating instrument capable of measuring in situ sea surface skin temperature to an accuracy of 0.1 K. The SST Radiometer is mounted on the port bridge wing, approximately 19.593m above the summer load line. The RV Investigator ISAR skin SST data are also supplied both in real-time (http://thredds.aodn.org.au/thredds/catalog/IMOS/SOOP/SOOP-ASF/VLMJ_Investigator/meteorological_sst_observations/catalog.html) and in delayed mode after reprocessing (e.g., http://thredds.aodn.org.au/thredds/catalog/IMOS/SOOP/SOOP-ASF/VLMJ_Investigator/meteorological_sst_observations/2016/ISAR-QC/catalog.html). These reprocessed files will be particularly valuable for satellite SST validation (as the ISAR measures SST at the same depth as measured by satellites) and are currently (2017) being used by EUMETSAT for Sentinel-3 SST validation and to JMA and Oceans University China for Himawari-8 SST validation. Further information can be found in the data and documentation links below.

Sampling of sediments has occurred on many voyages using sleds, dredges, grabs and corers. Records of sampling have been taken from a variety of sources and merged into one product. Two principal sources are the CSIRO Exploration and Mining voyages in 1990's and Geoscience Australia MARine Sediments (MARS) database downloaded in June 2013. MARS was queried for all RV Franklin and RV Southern Surveyor records. The rest of the sites have been extracted from voyage summary reports and where possible the MARS records have had additional details added including water depth and on-board commentary on the samples collected. Many of the sampling events do not have dates although the position is recorded quite accurately. Metadata records are missing for some voyages and will be added. In the interim, refer to the voyage reports for details including stations that failed to acquire samples.

CSIRO O&A Marine National Facility Voyage Tracks Overview (1986 - present)

The CSIRO O&A Optimized Voyage Tracks displayed in the WMS associated with this record are derived from underway GPS data collected since 1986 by Australia's Marine National Facility during research voyages. For most of these voyages, five minute underway digital data is available. The underway data set typically includes GPS location, Sea Surface Salinity and temperature, and Meteorology Station data. Later voyages also recorded digital echo sounder data. Individual metadata records have been created for each research voyage. The data is held in the CSIRO O&A Data Warehouse, which currently holds underway GPS data for more than 200 voyages.

Wildlife observations of seabirds, seals and cetaceans from RV Investigator and other vessels.

CSIRO O&A Wildlife Observations Overview

Wildlife observations from voyages have been collected over many earlier voyages as mentioned in the Biological survey overview metadata records . Most of those records have not been digitised or lodged with the Data Centre. More recently there have been surveys from the RV Investigator where the observations have been logged in on-line database. Observations cover birds, seals, cetaceans and ad-hoc observations of turtles and sea snakes. The main contemporary project looking at seabirds is Spatial and temporal variability in the distribution and abundance of seabirds by Principal Investigator Dr. Eric Woehler. Data from this project is progressively being published on a voyage by voyage basis to the Ocean Biodiversity Information System (OBIS), Atlas of Living Australia (ALA) and the Global Biodiversity Information Facility (GBIF). Details of the publishing mechanism, standards used and publishing site are on the OBIS Australia website http://www.obis.org.au
