Description
IN2023_V05 voyage data from the RV Investigator captures a month-long survey of the southeast Australian marine ecosystem. The archive contains raw data from over 40 instruments, including acoustic profilers, greenhouse gas analyzers, plankton samplers, and multibeam echosounders. It was curated by the CSIRO National Collections and Marine Infrastructure Information and Data Centre following the voyage in June-July 2023.
Use Cases
Analyze ocean current profiles from Lowered ADCP and shipboard ADCP data to model water mass movement.
Correlate CTD hydrochemistry data with Photosynthetically Active Radiation sensor readings to study phytoplankton productivity.
Map seafloor topography using Multibeam Echosounder EM710 and EM122 data alongside Sub-bottom Profiler records.
Investigate atmospheric-ocean gas exchange by comparing pCO2, Radon sensor, and Greenhouse Gas Analyser measurements.
Assess pelagic biodiversity through Environmental DNA samples, Continuous Plankton Recorder data, and Wildlife Observations of seabirds and cetaceans.
Strengths
Data collected from over 40 specialized oceanographic and atmospheric instruments during a dedicated research voyage.
Voyage documentation and processed data are made publicly available through the MNF Data Trawler portal.
Raw data archive is permanently hosted and curated by the authoritative CSIRO Data Access Portal.
Limitations
Specific row counts, file sizes, and data volumes for individual instrument datasets are not provided.
Raw data access may require an application process for non-CSIRO participants, potentially delaying analysis.
The temporal coverage is limited to a single 33-day voyage in 2023, capturing a snapshot rather than a time series.
