Rare, tiny find in West Australian waters

24.06.2004


A miniscule marine creature caught during a recent Indian Ocean research voyage is believed to be the first of its kind identified in the Southern Hemisphere

A miniscule marine creature caught during a recent Indian Ocean research voyage is believed to be the first of its kind identified in the Southern Hemisphere.The single celled organism, supporting what looks like 6 legs is a phaeodaria from the family coelodendridae, also known as a radiolarian. Measuring only 1.4 mm, the organism was found during an investigation of ocean eddies by the National Marine Facility, Southern Surveyor.

"It was a case of being in the right place at the right time with the right people," says PhD student Harriet Paterson, who discovered the radiolarian. Harriet works with the Strategic Research Fund for the Marine Environment (SRFME) a joint CSIRO-West Australian Government marine research team based at Floreat, Perth. "Our objective was to collect samples of marine life in ocean eddies and this was a complete surprise to us, and I’m sure to other researchers in this field from Northern Hemisphere institutions," Ms Paterson said. Ms Paterson detailed her research to colleagues during a science symposium in Perth yesterday (June 16).



The Director of SRFME, Dr John Keesing, said the discovery is an example of how state and federal agencies are coming together to tackle the problem of exploring and managing Australia’s vast and valuable ocean resources.

"Australia’s territory is 70 per cent ocean. We need more ocean scientists. We need to be able to provide hard scientific facts about our oceans that will allow legislators, regulators and industry to be able to address the challenge of managing our ocean resources.

"The West Australian Government, CSIRO Marine Research and the CSIRO Wealth from Oceans Flagship have come together to provide a program to train and supervise new PhD students in the area of marine science. This discovery is a direct result of that program," said Dr Keesing.

The find has excited scientists researching the micro zooplankton world. The pheodaria was captured in a sediment trap deployed within an ’upwelling’ eddy bringing cold and nutrient-rich deep ocean water to the surface by Dr Stephan Pesant a member of the University of Western Australia team lead by Dr Anya Waite, Centre for Water Research.

The micro zooplankton species is understood to live from depths of 100 to 5000 metres. Its food range extends from ocean algae to tiny shellfish. It consumes prey in the same manner as a spider, remineralising part of the ’ocean snow’ and helping to sustain other small forms of marine life.

Ms Paterson has searched the scientific literature and believe this is the first sample to be found in the Southern Hemisphere. The first sample was recorded during the world’s first oceanographic voyage by the British ship Challenger in the 1870’s, and then more than a century later, US scientist Dr Neil Swanberg collected 18 specimens down to a depth of 500 metres in one voyage from a submersible in 1986.

Im Focus: Light from a roll – hybrid OLED creates innovative and functional luminous surfaces

Up to now, OLEDs have been used exclusively as a novel lighting technology for use in luminaires and lamps. However, flexible organic technology can offer much more: as an active lighting surface, it can be combined with a wide variety of materials, not just to modify but to revolutionize the functionality and design of countless existing products. To exemplify this, the Fraunhofer FEP together with the company EMDE development of light GmbH will be presenting hybrid flexible OLEDs integrated into textile designs within the EU-funded project PI-SCALE for the first time at LOPEC (March 19-21, 2019 in Munich, Germany) as examples of some of the many possible applications.

The Fraunhofer FEP, a provider of research and development services in the field of organic electronics, has long been involved in the development of...

Im Focus: Regensburg physicists watch electron transfer in a single molecule

For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.

The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks...
