‘Black water’: The three Australian sites that are ground zero for climate change
In the summer of 2011, as flooding across Victoria and Queensland killed 35 people and left a $14 billion damage bill, something very different was happening on the other side of the country. Record summer ocean temperatures up to 5C above average represented the worst marine heatwave Western Australia had ever seen.
Congratulations Maria Jung - one of eight young researchers to receive a major boost to support for doctorate research in marine science. Working across a diverse range of innovative projects in ocean science, the eight PhD students were awarded a total of $92,000 through the 2020 Robson and Robertson Awards Scheme.
A Snapshot of 70 Years of Marine Research in Shark Bay: Ecological, Social and Economic
A new report launched this week by the Western Australian Marine Science Institution brings together the last seven decades of marine research on Gathaagudu, Shark Bay. Gary Kendrick hands the Report over to Malgana Traditional Owners.
Blue carbon, conservation economies & the great seagrass restoration
Gary Kendrick’s great love is the WA coastline and its seagrasses. Gary and colleagues have been at the forefront of seagrass restoration and the blue carbon movement more broadly. And with such a massive extent of coastline featuring globally significant carbon stores, World Heritage Sites, and deep community and cultural knowledge, the potential for WA is enormous.
With the future of fishing in Australia directly related to the quality of our waterways, one national not-for-profit has put the call out for recreational fishers to help conserve their beloved streams, lakes and estuaries.
Snapper habitat gets second dose of seagrass seeds
West Australian recreational fishers and divers have worked to restore the lost seagrass meadows of Cockburn Sound for the second consecutive year by collecting and spreading seeds to speed the plant’s restoration and improve the habitat for Pink Snapper.
Malgana people add their voice to science priorities for Shark Bay
Generations of Malgana people from Gatharragudu (Shark Bay) came together to start the process of understanding the decades of research that has been carried out in the World Heritage Site and to develop priorities for the future. Matt Fraser got the opportunity to share seagrass research firsthand.
Congratulations to Belinda Martin - selected as a finalist in the Exxon Mobil Student Scientist of the Year for her innovative research into seagrass microbes. The winners will be announced at an awards ceremony on 13 August 2019.
Shark Bay: A World Heritage Site at catastrophic risk
The devastating bleaching on the Great Barrier Reef in 2016 and 2017 rightly captured the world’s attention. But what’s less widely known is that another World Heritage-listed marine ecosystem was also devastated by an extreme marine heatwave in Western Australia in 2011. Safeguarding Shark Bay from climate change will require a coordinated research and management effort from government, local industry, academic institutions and local Indigenous groups.
Momentum builds to save seagrass as it disappears at a fast rate
‘Operation Posidonia’ launched in Port Stephens today. A team led by UNSW and the Sydney Institute of Marine Science is asking local communities to help restore endangered Posidonia seagrass meadows by collecting shoots that naturally become detached after large storms. Listen to the radio interview.
'Seeds for Snapper' restoring the seagrass meadows of Cockburn Sound
In an Australian first, hundreds of West Australian recreational fishers will be asked to take part in a trial to restore the lost seagrass meadows of Cockburn Sound. Cockburn Sound has lost some 80% of its seagrass habitat since the 1960’s, down from 4000ha originally, to 900ha today. OzFish Unlimited is leading this trial, with support from Recfishwest and researchers from the University of Western Australia, along with BCF.
The New York Times Magazine dedicated this issue to a single long story, 'Losing Earth: The decade we almost stopped climate change', by writer-at-large Nathaniel Rich with amazing photographs and videos by George Steinmetz, about the ten-year period from 1979 to 1989, the decisive decade when humanity settled the science of climate change and came surprisingly close to finding a solution. The world was ready to act. But we failed to do what was necessary to avoid a catastrophe. Rich's story is a gripping narrative that reads like a historical whodunit.
Adapting to ecosystem change in the Shark Bay World Heritage site
Five years after the release of a report into the Shark Bay World Heritage site recommended a coordinated collaborative approach was vital to understand changes in the ecosystem, more than 70 science and industry experts have joined forces to examine the threats and prioritise the research needed to save its status.
A new study published today in Nature Climate Change by an international team of researchers highlights the devastating effects of a marine heatwave in one of the world’s largest remaining seagrass ecosystems. This collaborative study found the death of seagrasses in the Shark Bay World Heritage Site from a 2010/11 marine heat wave released up to nine million metric tons of carbon dioxide (CO2) into the atmosphere over the following three years.
Study finds ways to avoid hidden dangers of accumulated stresses on seagrass
Hundreds of millions of cubic meters of vital seagrass meadows worldwide can potentially be at risk of collapse from accumulated effects of repeated dredging and natural stress - a QUT-led research project examines just what the main risks are in a newly published article in the Journal of Applied Ecology.
Seagrass research included in $14.75 million of Federal funding
Researchers at The University of Western Australia have received $14.75 million in funding for 26 projects through the Federal Government’s Australian Research Council. UWA received $9.6 million for 25 Discovery Projects including:
Saving seagrasses from dredging - new research finds solutions
Timing of dredging is the key to helping preserve one of the world’s most productive and important ecosystems - seagrass meadows. The study, published overnight in Nature Communications, was led by QUT researchers in collaboration with seagrass experts at ECU, JCU, and UWA.
Study identifies bottlenecks in early seagrass growth
Seagrass meadows, key nursery and feeding grounds for many kinds of marine life, are being lost worldwide to nutrient pollution, warming waters, and other ills. A new study published today by an international research team reveals bottlenecks in the growth of seagrass from seed to seedling, knowledge useful for improving seed-based restoration efforts.
On Sunday 8th October we lost a great champion for Australia’s aquatic environment with the passing of Professor Arthur McComb. Arthur has been instrumental in the growth of aquatic ecosystem science in Australia. The underlying theme of Arthur’s research was to understand the fundamental processes that control plant biomass in aquatic systems and the place of primary producers in the functioning of whole ecosystems. Arthur’s legacy will live on through his writings and his many students.
Are Coral Reefs on Death Row? A masterclass with Charlie Veron
Members of the Kendrick lab were privileged to spend the morning in a Masterclass with Charlie Veron. We covered topics from coral taxonomy, biogeography, ancient mass extinctions and the re-evolution of modern corals to reticulate evolution and climate change. Are they facing another mass extinction? - this time at the hands of rapid ocean warming and acidification, largely driven by our human desire to burn fossil fuels? The mornings topics provided for some lively conversation! Thanks to the UWA Institute of Advanced Studies for sponsoring this event.
OI formally launches the Robson & Robertson Awards

The R&R Award was established to honour the founders of the Oceans Institute and have been made possible by a donation from the Jock Clough Marine Foundation. The R&R Award supports early career researchers in pioneering global research to address ocean challenges in conservation, genetics and aquaculture. Matt's research will focus on developing innovative solutions to improve the conservation and management of our coastal ecosystems. The Award also provided additional funding for 3 of our PhD students Ana Giraldo, Joseph Turner, and Daniel van Hees.
Healing old wounds: restoring Posidonia australis in mooring scars
Efforts to restore seagrass in Port Stephens have been boosted by a significant NSW State government grant. The research team led by Adriana Vergés at UNSW/Sydney Institute of Marine Science will be developing methods to restore endangered Posidonia seagrass meadows through environmentally friendly moorings and seagrass revegetation.
The Indian Ocean Marine Research Centre (IOMRC) was officially opened today. The centre brings together more than 300 marine scientists across a variety of disciplines who will collaborate to increase knowledge in areas such as biodiversity, commercial and recreational fishing, tourism, indigenous engagement, climate change, oceanography, sustainable use of marine resources and the conservation of marine life and ecosystems.
Seagrass Restoration Network: Saving our seagrasses for future generations
A group of Australian and New Zealand marine scientists are building a Seagrass Restoration Network to foster communication between researchers, restoration practitioners, community groups, and government policy makers engaged in marine conservation and restoration activities. A new website was launched this week using funds kindly made available through The Nature Conservancy and Deakin University. This new initiative is being led by prominent scientists, Deakin University’s Dr Craig Sherman and Professor Gary Kendrick from The University of Western Australia.
Discover our local coastal biodiversity
Join Scientists from the School of Botanical Sciences (UWA) to make a complete survey of the wonderful plants and animals that live on our Perth beaches and near shore marine environment. Bring the family and spend the morning discovering and documenting living things in their coastal environment.
Western Australian Young Achiever Awards - 2017 finalists announced
Congratulations to Matthew Fraser who was recently named as a finalist for the Western Australian Young Achiever Awards in the Environment and Sustainability category. Matthew created the Cottesloe Ecosystem Research Project where undergraduate students research one component of the Cottesloe Reef ecosystem - plants, invertebrates, or fish. They add data to a pre-existing long term dataset to report on changes, providing valuable monitoring. The winners will be announced at the Awards Gala Presentation Dinner this Friday.
Marbà et al. (2015) selected for Journal of Ecology's new virtual issue
The Journal of Ecology have announced the creation of a new subject category: Global Change Ecology. To mark the occasion, they have prepared a special virtual issue titled 'Plants in a changing world: global change and plant ecology'. The virtual issue consists of 21 of the finest research published on global change over the last few years, including Marbà et al. (2015) 'Impact of seagrass loss and subsequent revegetation on carbon sequestration and stocks.'
WAMSI: Avoiding or reducing dredging during sensitive periods
The Western Australian Marine Science Institution (WAMSI) has just published an article which examines whether dredging operations suspended during generic windows of environmental sensitivity could reduce the impacts on marine life has found the marine invertebrates, seagrasses and macroalgae too diverse to be covered by a one-size-fits-all approach.
Climate-driven regime shift of a temperate marine ecosystem
Ecosystems over time have endured much disturbance, yet they tend to remain intact, a characteristic we call resilience. Though many systems have been lost and destroyed, for systems that remain physically intact, there is debate as to whether changing temperatures will result in shifts or collapses. Wernberg et al. show that extreme warming of a temperate kelp forest off Australia resulted not only in its collapse, but also in a shift in community composition that brought about an increase in herbivorous tropical fishes that prevent the reestablishment of kelp. Thus, many systems may not be resilient to the rapid climate change that we face.
Published: Identifying knowledge gaps in seagrass research and management: An Australian perspective
Gary, Marion, and Liz attended a Seagrass Workshop in July 2015, hosted by Deakin University's Centre for Integrative Ecology. The workshop was held as part of the Australian Marine Sciences Association conference and included over 50 seagrass experts and student researchers. The aim was to update and redefine strategic priorities in Australian seagrass research. Participants identified 40 research questions across 10 fields as priorities. A multidisciplinary approach will be needed to facilitate greater understanding of the complex interactions among seagrasses and their environment.
CSIRO has teamed up with BHP Billiton Petroleum and the University of Western Australia to welcome a fresh faced trio of scientists. The new PhD students will be conducting research to protect and conserve one of Australia’s most unique landscapes: the Ningaloo Reef.
Many plant species reproduce using sexual and asexual methods – and this can vary depending on environmental and genetic conditions. A large amount of energy goes into producing flowers and seeds for sexual reproduction, while vegetative growth through continuous expansion of the original plant(s) requires much less energy. Sexual reproduction produces new combinations of genes which may be advantageous in changing environments. Yet vegetative growth may also be seen as advantageous through the persistence of the same locally adapted genetic individuals.
Five young West Australian scientists are spending their summer working alongside researchers at Kings Park and Botanic Garden as part of the Kings Park scholarship program. One of this years successful scholars is Henry Lambert, a UWA zoology and marine science double major, who will be researching alongside Elizabeth Sinclair, learning about the genetics of seagrass restoration.
Why are Australia’s marine parks being reviewed so soon after they were signed off?
The current government review of Australia’s proposed network of marine parks, called the Commonwealth Marine Reserves (CMRs), seems rather premature. After all, the management plans were approved only in March 2013 and as yet only the southeast region is being actively managed.
Dead whales are expensive – whose job is it to clear them up?
A whale carcass can be a big headache – just ask the locals at Broulee Beach in southern New South Wales, where a dead whale washed back ashore last month despite already having been towed out to sea just after Christmas.
An international team of researchers has found that the disappearance of seagrass meadows could be contributing to the release of carbon dioxide which has been stored for centuries. Researchers studied the impact of disappearing seagrass meadows (Posidonia australis), at Oyster Harbour in Albany, where long-term restoration of seagrass has been highly successful. They used sediment-dating techniques to quantify the accumulation of carbon in repopulated areas and calculate the erosion of carbon in areas that were not revegetated.
Climate change threatens Western Australia’s iconic Shark Bay
In the summer of 2010-2011 Western Australia experienced an unprecedented heatwave — but not on land. Between December 2010 and April 2011, sea temperatures off the WA coast reached 3ºC above average, and for two weeks peaked at 5ºC above average — 28ºC compared to the normal 23ºC. The effects were drastic. Corals bleached, and the makeup of the usually temperate south west marine ecosystems shifted to more tropical — both in fish, and algae.
Seagrasses are considered the forests of the marine world, but they have been in global decline for years, so news that Western Australian researchers have successfully transplanted seagrass is considered a significant development. ABC radio's Desley Blanch speaks with Gary Kendrick.
Seagrass meadow restoration trial using transplants – Cockburn Sound, Western Australia
Cockburn Sound is a natural embayment approximately 16 km long and 7 km wide, to the west of the southern end of the Perth metropolitan area. Its seagrass meadows have been reduced in area by 77% since 1967, largely due to the effects of eutrophication, industrial development and sand mining. To answer a range of questions relevant to seagrass restoration, we (i) carried out a transplant trial, (ii) monitored the impact and recovery of the donor site, and (iii) retrospectively assessed genetic diversity in the transplant site.
Shark Bay stromatolites at risk from climate change
Climate change – resulting in more frequent flooding of the Wooramel River that leads into Shark Bay – may threaten the unique stromatolites that make Shark Bay a World Heritage site. These stromatolites – rocky structures formed over millennia by blue-green algae or cyanobacteria – thrive in Shark Bay’s Hamelin Pool, where an unusual undersea landscape has created an environment twice as saline as normal seawater.
Science and art combine to engage Aboriginal students at One Arm Point
Angela Rossen's novel combination of art and science is switching kids on to the animals that live in the marine environment. The result is both beautiful and informative and is a source of pride for the children involved.
