Underwater towed video from the Wessel Marine Park (IN2019_T02)
This record describes the towed video component from the from the Marine National Facility (MNF) RV Investigator research voyage IN2019_T02, titled "Deep seascapes of the Great Barrier Reef: Uncovering submarine canyons and landslides." The voyage took place between October 4 and October 14, 2019 departing from Brisbane (QLD) and arriving in Darwin (NT).
Four 1500 m video transects were undertaken across a range of geomorphic features and depth gradients focussed on a deep hole feature within and adjacent to the Wessel Marine Park, on October 11, 2019.
The benthic environment in the study area was highly turbid with strong currents, and associated imagery can therefore only be used for habitat classification, coarse morphospecies identification, or defining broad biological communities.
Onboard habitat annotations are included as an excel file, with camera positioning included.

Resource lineage
- Statement
- Towed imagery transects were selected using seabed mapping from multibeam operations. Towed imagery operations followed national protocols, with the exception that the recommended downward-facing stills camera was substituted with the forward-facing stills camera on the vessel’s deep-tow system. Underwater imagery was acquired with the Marine National Facility’s Deep-Towed Camera system. The camera was towed for approximately 1000 m at 1 – 1.5 knots (~30 minutes) along geomorphic and depth gradients of the seafloor.
