Description
An End of Voyage archive from the Marine National Facility RV Investigator voyage IN2023_V05, which studied changes in the southeast marine ecosystem. The voyage occurred from June 28, 2023 to July 30, 2023, departing from and returning to Hobart. Data were collected using over 40 instruments, including ADCPs, CTDs, echosounders, greenhouse gas analyzers, plankton samplers, and environmental DNA collectors, and are curated by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.
Use Cases
Modeling ocean currents and water column structure based on Acoustic Doppler Current Profiler (ADCP) and CTD data.
Analyzing marine biodiversity and plankton populations based on Continuous Plankton Recorder (CPR) and Environmental DNA (eDNA) samples.
Studying seafloor topography and sub-bottom geology based on Multibeam Echosounder (EM710, EM122) and Sub-bottom Profiler (SBP120) data.
Investigating atmospheric-ocean gas exchange based on Greenhouse Gas Analysers (Picarro) and pCO2 measurements.
Assessing fisheries resources and biomass based on Fisheries Echosounder (EK60, EK80) and trawl data.
Strengths
Data collected during a dedicated 33-day research voyage (June 28 to July 30, 2023) with a clear scientific objective.
Archive includes measurements from over 40 distinct instruments, covering atmospheric, oceanographic, biological, and geophysical parameters.
Data are permanently archived and curated by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment for large-scale modeling.
The raw data archive format includes PNG and HTML files, suggesting a mix of data and documentation that may require extraction.
