Dr Norm Duke, a marine biologist with The University of Queensland's Centre for Marine Studies, has been engaged by PTTEP Australasia (Ashmore Cartier) Pty Ltd to examine the potential risk to coastline ecosystems, following the Montara oil and gas leak 200 km north-west of Western Australia's Kimberley coastline.
Through a contract negotiated with UQ’s main commercialisation company, UniQuest, Dr Duke will spend 10 days this month conducting an independent baseline ecological assessment aerial survey with 20 ground sampling sites along the shoreline from Darwin to Broome (excluding Ashmore reef).
The first study of its kind for the area, the survey aims to capture the current and un-impacted condition of the relevant coastal species and habitats.
From a chartered helicopter, data will be collected in the form of high-definition video and still photography, with correlating GPS location information, to establish a baseline and permanent record of the coast prior to any potential impact from the oil spill. Ground surveys will collect samples of sediment, seawater and biota.
If any oil reaches the coastline, the baseline data is expected to help determine whether any damage to the local ecosystems observed was pre-existing or the result of the spill or the clean-up. The study will also be used for any future monitoring of the area.
The Australian Maritime Safety Authority said (as at November 3) the oil spill was approximately 71 kilometres from the West Australian coastline and about 237 kilometres from the Indonesian coastline (see end note).
Dr Duke, recognised worldwide for his specialist knowledge of mangrove forest and tidal wetland ecosystems, and a former marine investigator for the Australian Institute of Marine Science and the Panama-based Smithsonian Tropical Research Institute, believes the survey sets a positive example for all industry types working near vulnerable shoreline habitats.
"This survey is a proactive effort to have a better understanding of environmental impacts on the shoreline before any potential situation occurs," Dr Duke said.
"It's important to understand what is 'normal' for any individual stretch of shoreline. In mangroves and salt marsh areas, for example, plant die-back and washed-up carcases maybe common at times.
“Once we know what the baseline conditions are, if this oil spill or any other type of threat reaches the area we will have a much better idea of the strength and extent of the impact and what needs to be done to recover and rehabilitate potentially affected areas."
Dr Duke confirmed that the scope and design of the study would incorporate scientific monitoring standards for both aerial and ground surveys, as specified in the Monitoring Plan for the Montara Well Release in the Timor Sea agreed between PTTEP and the Department of the Environment, Water, Heritage and the Arts (DEWHA).
The data will be collected and interpreted independently, with PTTEP submitting the final report to DEWHA for public release.
Two other experienced UQ researchers with specialist skills will be assisting Dr Duke.
Jock Mackenzie is writing his PhD thesis on mangroves as indicators of estuarine health. Alex Haller has experience with mapping software and satellite imagery.
All members of the crew have extensive experience in Australian and overseas marine survey work and have undertaken certified Sea and Safety Survival Underwater Escape training.
UniQuest Managing Director David Henderson said the PTTEP contract was a valuable investment, not only for the environment, but also in developing stronger connections between multinational companies and Australian university research.
"University researchers are in demand because they can offer impartiality and credibility – two very important qualities for businesses making significant economic decisions that impact on their corporate reputation," Mr Henderson said.
"UniQuest makes it possible for businesses of all sizes here and overseas to access hundreds of experts in many fields of research, as well as the world-class technical and human resources of UQ’s research facilities.
"Helping companies like PTTEP engage the best teams for the task, especially when timing is a critical factor, also offers researchers new field experiences and the satisfaction of knowing their efforts are adding value to industry and community development."
The single baseline survey will be conducted from the second week of November, with Dr Duke and his team travelling from Darwin to Broome by helicopter and boat.
Note: Best estimates of the distance of oil from coastlines are based on observations from aircraft and will vary daily depending also on what land point the measurement is taken and the direction the oil is located at the time.

About Dr Norm Duke (MSc PhD)
Dr Norm Duke, Marine Botany research leader at the UQ Centre for Marine Studies, has more than 30 years ecological research experience in tropical coastal ecosystems, particularly for mangrove forests of Australia and Central America, and many other locations around the world. Dr Duke has formed numerous multi-disciplinary teams for applied biological assessment and environmental surveys/inventories. He is recognised as an international authority regarding floristics, distribution, biogeography, productivity, rehabilitation, and the impact of large oil spills and other disturbances.
In recent years, Dr Duke has focused on assessing historical and short term change in mangrove stands, particularly regarding management issues and habitat restoration; and climate change, conducting studies of genetic variation of mangrove plant species worldwide. Human effects have also been considered in his broad-scale studies of pollutant stress. Dr Duke’s findings contribute to mitigation strategies (e.g. the use of dispersants, bioremediation and mangrove planting) and standardising practical assessment techniques and monitoring methods. He has published more than 100 peer-reviewed, scientific papers, book chapters and technical reports, and makes regular presentations at international seminars and public meetings. Copies of his book, Australia’s Mangroves, and accompanying waterproof wheel key can be purchased from UniQuest.
About PTTEP Australasia
In February 2009, Coogee Resources Limited was acquired by a subsidiary of PTT Exploration and Production Public Company Limited (PTTEP) and renamed PTTEP Australasia Limited (PTTEP AA). PTTEP is Thailand’s national petroleum exploration and production company and is one of the nation’s largest publicly-listed companies, with more than 40 projects around the world. PTTEP AA will continue the development of the Montara (and the other projects) in the Timor Sea.
