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.

This record provides an overview of the NESP Marine and Coastal Hub scoping study - "National Areas of Interest for Seabed Mapping, Characterisation and Biodiversity Assessment". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Seabed and marine biodiversity data are time-consuming and costly to collect, so it is imperative that acquisition is focused on areas that align with end user priorities. The value that different stakeholders place on seabed and biodiversity data can be difficult to determine. Therefore, a shared process for identifying survey priorities is required to ensure the maximum shared benefit of future survey investment across research users, funding agencies, infrastructure providers, as well as the wider marine research community. The project aimed to assist with the planning and prioritisation of marine surveys (both physical and biological) by scoping a prioritisation framework for marine surveys undertaking physical and biological seabed data collection in Australia. Focused workshops and targeted engagements with seabed mapping organisations were used to develop a standard set of metadata for agencies to define spatial Areas of Interest (AOI). The standard metadata were used in a prototype prioritisation framework that allows users to transparently and consistently rank and prioritise survey work or data delivery processes. The prioritisation is then based on rankings established by defined sets of criteria. A web-based AOI submission tool and mapping publication service was then developed for these defined areas as part of the AusSeabed Survey Coordination Tool. Adoption of this tool facilitates the development of an interim national areas of interest product to inform future survey planning. This product supports both the needs of Parks Australia's network Science Plans, and consideration of information needs for Indigenous Protected Areas within Sea Country. Outputs • National Areas of Interest polygon & interactive map [dataset] • Code for Survey Coordination Tool [Github Repo] • Final Report with Value Prioritisation Framework [written]

Time Series video to support Project C3 of the Marine Biodiversity Hub NESP programme 2015/2016. The video illustrates coastal change at the Southern end of Stradbroke Island QLD, using 118 Landsat observations from within the Australian Geoscience Data Cube (AGDC) from 1987-2016.

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project C3 - "Change detection and monitoring of key marine and coastal environments – application of the Australian Geoscience Data Cube". For specific data outputs from this project, please see child records associated with this metadata. -------------------- This project aims at leveraging the extensive time-series of earth observation image data in the Australian Geoscience Data Cube (AGDC) by developing change detection algorithms to analyse key environmental parameters in the coastal and marine zone. Spatial information produced by this project can inform management decisions, and assist in evaluating management action outcomes, by providing a quantifiable measure of historical change and ongoing monitoring and change detection capabilities. In Phase 1 of this project we aim to demonstrate the capability of using the AGDC through the development of an inter-tidal zone change detection algorithm and data set, with a view to developing and implementing an expanded range of stakeholder targeted algorithms to inform decision making processes in Phase 2. Planned Outputs • Progress Report • Demonstrator summary Report • Data Products (GIS maps and data, delivered from the GA website as a web service) • Marine Biodiversity Hub article • Pesentation at the Australian Marine Science Association Conference.

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project B3 - "Enhancing access to relevant marine information –developing a service for searching, aggregating and filtering collections of linked open marine data". For specific data outputs from this project, please see child records associated with this metadata. -------------------- This project aims to improve the searchability and delivery of sources of linked open data, and to provide the ability to forward collections of discovered data to web services for subsequent processing through the development of a linked open data search tool. This work will improve access to existing data collections, and facilitate the development of new applications by acting as an aggregator of links to streams of marine data. The work will benefit managers (i.e. Department of the Environment staff) by providing fast and simple access to a wide range of marine information products, and offering a means of quickly synthesizing and aggregating multiple sources of information. Planned Outputs • Delivery of open source code to perform the search functions described above. • A simple initial web interface for performing the search and retrieval of results. • Expanded collections of data holdings available in linked open format, including the use of semantic mark-up to enable fully-automated data aggregation and web services. In particular, addition of linked-open data capability to a pilot collection of existing data sets (GA, CERF and NERP data sets).
