Recordings of ship noise were analysed to build a catalogue of ship noise signatures in Australian waters, including source spectra and source levels. The data described by this record is derived from an initial set of five deployments by the Integrated Marine Observing System (IMOS) acoustic observatories. This dataset has been snapshotted to coincide with the conclusion of the National Environmental Science Program (NESP 1) Hub in May 2021, but is an ongoing dataset. For the most current version of this data, please contact Christine Erbe (see Point-of-Contact).
This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project E3 - "Microplastics in the Australian marine environment". No data outputs are expected for this project. -------------------- A literature review will firstly identify key marine microplastics research and policy development internationally, with a focus on research that is contextual to microplastics in the Australian marine environment From this literature review, an options paper will be developed to explore the most feasible and impactful policy approaches for the Australian context to reduce both intentionally added and not intentionally added microplastics in the marine environment (it would be beneficial to understand the policy options that can address both categories of microplastics because the options are different). These two reports would form the basis of a one day workshop that will draw together policy-makers, researchers and relevant industry peak bodies to discuss and recommend policy and other options to limit the release / impact of microplastics in the environment. A workshop report will be drafted to summarise findings, recommendations, and next steps (including identifying gaps in both science and policy will inform any future work required). The report will provide evidence to underpin the development of national policy aimed at reducing microplastic pollution, including by identifying priority actions to deliver Australia’s 2018 National Waste Policy .
This project quantified underwater noise from ships in Australian waters, with the ultimate goal of guiding the management of noise impacts on marine fauna. This record describes a gridded map of cumulative sound exposure from shipping in the Australian EEZ for a typical April-September period.
