Foundation WAMSI Chairman inducted into the WA Science Hall of Fame

WAMSI’s Foundation Chairman, Dr Bernard Bowen, was last night inducted into the WA Science Hall of Fame at the WA Science Awards Gala Dinner.

Dr Bernard Bowen was instrumental in establishing WAMSI during the inception and start-up period 2005 – 2007. Dr Bowen is currently the Chair of the International Centre for Radio Astronomy Research [ICRAR] which he took on after finishing as the WAMSI Chairman in July 2007. Dr Bowen has retained strong links with the marine science community through WAMSI however and is currently the Chairman of the WAMSI Strategic Programs Committee which advises the Board on strategic issues.

WAMSI CEO, Dr Steve Blake said “This award bestowed on Dr Bowen is very well deserved indeed. He has provided over 50 years of loyal service and scientific leadership to the State. Dr Bowen’s leadership across multiple science disciplines within WA is legendary. Dr Bowen’s focus on good governance, fair process and institutional enablement combines to give all joint venture participants confidence which encourages the ensuing co-investment and additional partnering opportunities.”

Scientists are studying the impact of a massive influx of fresh water and sediment to Shark Bay in Western Australia as a result of the area’s largest ever flood event recorded in December last year.

Shark Bay was declared a World Heritage Area in 1991, and has the distinction of being one of the few places in the world that satisfies all criteria for World Heritage listing.

The bay’s vast seagrass meadows – the most diverse assemblage of seagrasses in the world – support globally significant populations of endangered dugongs and turtles.

‘Seagrasses are important as the basis of the bay’s food web,’ said CSIRO researcher, Dr Mat Vanderklift. ‘An array of invertebrates feed on them, fish feed on the invertebrates, and predators like dolphin feed on the fish.

‘The meadows also provide a nursery for juveniles of many species, including crabs and prawns.’

As well as the CSIRO Wealth from Oceans Flagship, the flood-impact study involves The University of Western Australia (UWA), Curtin University and the WA Marine Science Institution.

A major ocean warming [marine heatwave] event occurred along the WA west coast from November 2010 until March 2011 influenced by a very strong La Nina event [opposite to El Nino] that caused masses of tropical water to flow between Indonesia and NW Australia and maintained very high ocean temperatures as it moved south down the west coast of WA. This was the same La Nina event that caused the incredible rain and flooding in eastern Australia during the same period of time.

At the height of the “heatwave”, temperatures of 3.5 deg C over ambient levels were recorded. This provides a major “shock” to the marine environment and caused fish kills and extensive coral bleaching in areas not accustomed to the sudden onset of high temperatures. Tropical fish species ended up much further south than their usual predicted ranges. Graphics depicting the southward migration of this heatwave event can be seen at: http://www.fish.wa.gov.au/docs/pub/Highlights/marine-heatwave.php

In some cases, these are the warmest sea temperatures ever recorded for these regions and they appear to have been influenced by a much stronger than usual Leeuwin Current over summer, associated with the very strong La Nina event. The baseline information collected through SRFME and WAMSI over the last 10 years has allowed marine scientists to begin to quantify the magnitude and significance of the event and also begin to predict the ongoing implications for Western Rock Lobster recruitment, prawns, scallops, finfish etc. It further illustrates the importance of establishing marine scientific baselines and ongoing monitoring. The extent of the coral bleaching has been reported as high as 90% in some parts of the Mid West around places such as Shark Bay. Scientists will now continue to monitor the recovery as the La Nina event continues to break down. Some marine scientists are suggesting the marine heatwave “event” may be a likely indication of what to expect in the future with predicted increased climate variability affecting the marine environment, especially ocean warming, as we move into the future.

On 14 June 2011, WAMSI was invited to participate in the Annual Indigenous Ranger Training Day held at Middle Lagoon on the Dampier Pennisula, north of Broome. Ranger groups came from throughout the Kimberley region.

The WAMSI CEO, Dr Steve Blake, was invited to present background and technical information on the marine environments along the WA coast with a particular focus on the Kimberley coastal areas. Also covered were: marine science research techniques, satellite tracking techniques, recent whale survey results, marine data management, international whale monitoring networks, migration patterns of humpback whales, the role of Kimberley coast as part of the annual migration, and the potential roles for rangers in both whale monitoring and broader marine science activities around the Kimberley coast. Four training sessions involving 80 Indigenous Rangers and participating Elders were conducted at the Two Moons Whale and Marine Research Base, concluding with Q & A and then a “hands-on” session with parts of a humpback whale skeleton for view. Steve Blake said “WAMSI is delighted to be able to assist with the training activities as part of the highly successful Aboriginal Ranger Programs in the Kimberley region.”
