IN2023_V05 Tasman Sea Bathymetry 10m - 210m Multi-resolution AusSeabed products

This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2023_V05 titled "Untangling the causes of change over 25 years in the southeast marine ecosystem". The voyage took place between June 26 and July 30, 2024, departing from Hobart (TAS) and arriving in Hobart (TAS).

The purpose of this voyage was to repeat fishery and ecosystem assessments conducted 25 years ago, to document changes and establish a new biological and environmental baseline to help answer three broad questions:
1. How and why have fish assemblages and species abundances changed in the southeast ecosystem, and can the causes be mitigated?
2. How does this affect the multiple-use management of the region, particularly conservation and biodiversity management of Australian Marine Parks and the hive of activity from fisheries, oil & gas, and renewable energy sectors?
3. What are the implications for marine spatial planning and adaptive management in the sectors that use the marine ecosystem?

The dataset contains bathymetry grids of 10m to 210m resolution of the Tasman Sea produced from the processed EM122 and EM710 bathymetry data.
