Australasian ocean currents
Ocean currents have a significant impact on climate, and are in turn shaped by climatic conditions. The four main currents in the Australasian region are the Antarctic Circumpolar Current, the Leeuwin Current, the Indonesian Throughflow and the East Australian Current.
New climate change research team established
One of Australia's leading climate change modelling experts, CSIRO Wealth from Oceans Flagship’s Dr Wenju Cai, has been awarded a five-year CSIRO fellowship to establish a new research team examining climate influences on Australia.
Hitomi the bigeye tuna puts CSIRO research on radar
Want to know where Mirella the gold spot trevally or Nero the spangled emperor hang out? Or how about where Hitomi the bigeye tuna, Papa the whale shark, and Galileo the tiger shark patrolled the southern oceans?
Scientists question fisheries health test
A measure widely advocated as a means of assessing the health of marine ecosystems is an ineffective guide to trends in biodiversity, and more direct monitoring is needed, a new study has found.
Deep thinking on the world’s oceans
The world's deep ocean researchers – scientists whose field of interest extends into the uncertain world below about 2000 metres – met in Hobart this week to discuss deep ocean changes, their causes and their implications.
Global warming’s influence on El Niño still unknown
The climate of the Pacific region will undergo significant changes as atmospheric temperatures rise but scientists can not yet identify the influence it will have on the El Niño-Southern Oscillation (ENSO) weather phenomenon.
Scientists offer new take on selective fishing
A new, less selective approach to commercial fishing is needed to ensure the ongoing productivity of marine ecosystems and to maintain biodiversity, according to a paper in the Proceedings of the National Academy of Sciences of the United States of America.
Massive Southern Ocean current discovered
A deep ocean current with a volume equivalent to 40 Amazon Rivers has been discovered by Japanese and Australian scientists near the Kerguelen plateau, in the Indian Ocean sector of the Southern Ocean, 4,200 kilometres south-west of Perth.
New coastal research body to turn science into action
An A$11 million collaboration aimed at helping Australia translate science into practical applications for adapting to climate change, population growth and other coastal pressures will be launched today in Perth.
Warming Indian Ocean – impacts to be discussed
The impacts of a warming Indian Ocean on Western Australia’s climate, environment and fisheries will be discussed today in Perth by scientists at a Western Australian Marine Science Institution (WAMSI) symposium.
Southern Ocean winds open window to the deep sea
Australian and US scientists have discovered how changes in winds blowing on the Southern Ocean drive variations in the depth of the surface layer of sea water responsible for regulating exchanges of heat and carbon dioxide between the ocean and the atmosphere.
Marine reserves mend food chains, link by link
Conservation managers need to take a long-term view when assessing the value of marine protected areas, according to a paper in today’s Proceedings of the National Academy of Sciences of the United States of America.
Anglers urged to share tales of longtail tuna
Coastal anglers are being encouraged to help ensure the long-term sustainability of Australia’s newest ‘recreational only’ species, the longtail tuna, by reporting catches using a new online system.
Helping Albacore tuna come out of the can
Scientists are set to study the earbones and organs of more than 2000 albacore tuna to better understand the growth, age and breeding patterns of this increasingly important species.
