Research themes

  • Urbanisation


    Sydney Harbour is Australia's largest, and most iconic, urbanised estuary. This makes SIMS an ideal place from which to understand, and help manage the pressures of urbanisation on the harbour and coastal ecosystems.

  • Biodiversity


    Sydney Harbour is one of the most biologically diverse harbours in the world. SIMS scientists are using both traditional and modern molecular techniques to expand our knowledge of this immense biodiversity.

  • Climate Change

    Climate Change

    The oceanography of the east coast of Australia is dominated by the East Australian Current. This current is increasing in strength making South-East Australia a global hot spot for climate change. SIMS is ideally placed for studying the causes and impacts of climate change in marine systems.

  • Ocean Resources

    Ocean Resources

    The ocean provides a wealth of resources for our use. SIMS scientists' research on the sustainable use of ocean resources is comparably broad, ranging from studies of the molecular mode of action of potential new pharmaceuticals to enhancing fish and prawn stocks along our coast.

  • Marine Management

    Marine Management

    From exploitation of key fisheries to conservation of endangered species, marine management relies on science to inform policy decisions. SIMS research is playing a critical role in managing our marine environment.

  • 2017 Tony Roach Award Winner


    SIMS and the New South Wales Office of Environment and Heritage (OEH) are pleased to announce the winner of the 2017 Tony Roach Prize in Marine Environmental Science. This year’s winner is Dr. Jeff Kelleway from Macquarie University for his paper in the journal Global Change Biology entitled: “Seventy years of continuous encroachment substantially increases 'blue carbon' capacity as mangroves replace intertidal salt marshes".

  • SIMS Director wins AMSA Jubilee Award


    Congratulations to Professor Peter Steinberg, Director & CEO, SIMS on his 2017 AMSA Jubilee Award. The award for excellence in marine research is presented to a scientist who has made an outstanding contribution to marine science research in Australia. Peter is a renowned authority in the areas of marine chemical ecology and surface colonisation as well as a leading proponent of the macro-micro approach to environmental microbiology. SIMS is delighted to have won two out of the past three annual awards. Professor Maria Byrne of University of Sydney won in 2015.

  • NSW Government support for SIMS


    21st May 2017


    SIMS was delighted to host a recent tour of the facilities by Premier Gladys Berejiklian. The premier was at SIMS to announce the NSW Government's support for the development of a business plan around an exciting SIMS initiative, a proposal for a Centre for Urban Marine Innovation on Sydney Harbour.


    The NSW government has been a long term supporter of facility developments at SIMS, reflecting the governments ongoing commitment to marine science research.

  • Bright clouds could help curb coral bleaching


    The Great Barrier Reef is one of the most spectacular natural wonders of the world, but with two-thirds of the reef already devastated by coral bleaching, scientists fear that the entire system has reached a critical tipping point.

    In an effort to curb further bleaching and protect the delicate coral communities below, Sydney Institute of Marine Science researcher, Dr Daniel Harrison and colleagues from the Ocean Technology Group at the University of Sydney, are investigating whether bleaching can be effectively mitigated by temporarily increasing the amount and ‘brightness’ of cloud cover during times of heat stress to the reef.

  • Congratulations to Daniel Harrison


    2017 Myer Innovation Fellowship winner


    SIMS is pleased to announce that Daniel Harrison from the USYD has won a Myer Innovation Fellowship for 2017, for his submission “Temporary Cloud Intensification - A method to save the Great Barrier Reef for future generations?”. dan harrison Daniel will be working with the CSIRO & the eReefs biogeochemical model to investigate whether coral bleaching can be mitigated by temporarily increasing the amount & ‘brightness’ of cloud cover during times of heat stress. .

  • Our oceanographer seals


    ABC news, 25th February 2017


    The ABC accompanied a team of scientists, including SIMS' Clive McMahon tracking elephant seals as part of the Integrated Marine Observing System (IMOS). Elephant seals dive almost continuously while at sea, gathering information including temperature and salinity wherever they travel and giving scientists new insights into remote and previously inaccessible locations.SIMS seal dinner

  • Underwater video reveals culprits behind disappearance of NSW kelp forests


    Seaweed-eating fish are becoming increasingly voracious as the ocean warms due to climate change and are responsible for the recent destruction of kelp forests off the NSW north coast near Coffs Harbour, research shows.

    “Kelp forests provide vital habitat for hundreds of marine species, including fish, lobster and abalone” says study first author Dr Adriana Vergés of UNSW and SIMS. “As a result of climate change, warm-water fish species are shifting their range and invading temperate areas. Our results show that overgrazing by these fish can have a profound impact, leading to kelp deforestation and barren reefs.

  • Shallow Reefs off Singapore survive in the face of adversity


    An analysis of the health of highly impacted coral reefs off Singapore during a 27-year long period has shown they are more resilient to the impacts of human activity and warming than expected. The study by the team, which includes researchers from UNSW and SIMS, the National University of Singapore, Nanyang Technological University, and Singapore’s National Parks Board, is published in the journal Scientific Reports. Study senior author Professor Peter Steinberg from UNSW / Sydney Institute of Marine Science (SIMS) adds: “This is by no means a cause for complacency regarding the state of our reefs, but rather highlights that if we can reduce local stressors, reefs are more likely to be able to rebound from the effects of global stressors such as climate change.”

  • Time to tackle urban coastlines


    SIMS Media Release, 25 May 2016


    A collaboration between the Sydney Institute of Marine Sciences (SIMS) and a Melbourne-based think tank is aiming to transform harbour shorelines around the world. In many harbours, including Sydney Harbour, more than 50% of the shoreline has been converted to seawall. These sandstone / concrete coastlines reduce biodiversity, and are commonly dominated by pest species.

    To find ways of addressing this problem, SIMS is conducting a 12-month project using concrete seawall tiles by Reef Design Lab, a not-for-profit design studio and think tank based in Melbourne. The tiles are being retrofitted to seawalls at two sites in Sydney Harbour (Balmain and Waverton).

Long Term Projects

World Harbour Project

Initiated by SIMS, the aim of the World Harbour Project is to link, facilitate and enhance programs of research and management across major urban harbours and ports of the world.


SIMS operates the NSW node of the Integrated Marine Observing System (IMOS). IMOS is a nation-wide collaborative program which uses the latest advances in technology to observe the oceans. The program has strong links with similar international programs and agencies.

Sydney Harbour Research Program

SIMS is conducting a multidisciplinary research project. The objectives are to identify, preserve and enhance the resilience of those species and habitats in Sydney Harbour that have high ecosystem and conservation value, and to enhance the capacity of relevant government departments to make key management decisions regarding the Harbour.

OEH Coastal Processes and Responses Node

The NSW Office Of Environment and Heritage (OEH) has established the NSW Adaptation Hub to generate the key information necessary to manage the consequences of environmental change in NSW. There are three research Nodes within the Hub, and SIMS manages the Coastal Processes and Responses Node.
