The Murujuga Rock Art Monitoring Program is the most extensive scientific study to examine the impact of industrial air emissions on the marni (rock art engravings) of Murujuga, an area covering the Burrup Peninsula and Dampier Archipelago in Western Australia.
This document presents the data collection, laboratory studies and analysis undertaken within the second year of scientific studies.
Key messages in this report:
- Measurements of rainfall and deposition over the past two years are neutral or slightly alkaline
- Air quality data collected over the past 18 months generally aligns with previous modelling
- The upper layer of granophyre rocks, one of the five rock types being investigated, has elevated porosity (the open spaces in rocks) in a region close to Dampier
- Data collected to date is sufficient to determine initial levels of safe air quality for the rock art.
- In the final years of research, the scientists will refine and determine final safe air quality criteria. These will be monitored to ensure the long-term protection of the rock art.
A summary of the findings can be found in the Murujuga Rock Art Monitoring Program: Research Summary Year 2. This report should be read with:
