Brief description

The Marine chapter of the 2016 State of the Environment (SoE) report incorporates multiple expert templates developed from streams of marine data. This metadata record describes the Expert Assessment "Pressures on the marine environment associated with marine mining". The full Expert Assessment, including figures and tables (where provided), is attached to this record. Where available, the Data Stream(s) used to generate this Expert Assessment are accessible through the "On-line Resources" section of this record. ---------------------------------------- DESCRIPTION OF THE PRESSURE A wide variety of mineral resources exist within Australia’s maritime jurisdiction (see Table 1 in attached Expert Assessment).

Notes

Purpose
Marine mining is limited in Australian waters. It is not clear how the 2011 assessment was determined given the lack of information on impacts.
