This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project D1 - "Ecosystem understanding to support sustainable use, management and monitoring of marine assets in the North and North-west regions". For specific data outputs from this project, please see child records associated with this metadata.

--------------------

Effective management of marine assets requires an understanding of ecosystems and the processes that influence patterns of biodiversity. Focusing on the North and North-west regions, this project will leverage previous research to improve ecosystem understanding through a synthesis of existing information and by making testable predictions about the character and extent of conservation values, including for key ecological features (KEFs) and Commonwealth Marine Reserves. End-users and stakeholders will benefit from improved regional descriptions of marine ecosystems and uncertainty statements. In turn, this will inform prioritisation of future investments in monitoring marine ecosystems and State of the Environment reporting.

Planned Outputs

• A report on the synthesis (based on collations completed in 2015) of datasets and models for the North and NW identifying areas of greatest information coverage, gaps and themed to CMRs and KEFs in those regions. This report will also describe key spatial patterns in biodiversity (benthic and pelagic) and associations between benthic environments, fish and megafauna and large scale processes (e.g. oceanography).

• Predictions and related products (maps) of the spatial distribution of biodiversity across the Oceanic Shoals CMR that encompasses benthic habitat, pelagic and demersal fish and megafauna communities. This will provide an example/test case at the National Prioritisation Workshop of how confidently predictive modelling can be used to describe assets and values in data poor areas to inform management and monitoring.

• An updated conceptual model of ecosystem processes (benthic and pelagic) within the Oceanic Shoals CMR based on extension of modelling into pelagics.

• A review of existing knowledge of the Ancient Coastline KEF.

• A qualitative model of Glomar Shoal KEF (to be confirmed in consultation with DOE).

• Communication products that capture activities and general interest stories of scientific results disseminated through NW Atlas social media links.

• Upload of new relevant spatial data layers in NW Atlas for management and planning, and engagement with end users to maximize uptake of the NW Atlas products.
