The Marine National Facility research vessel Investigator arrived in Sydney earlier this week, which made for some spectacular photos of the ship against grey clouds and a dark harbour!
The 94 metre vessel tied alongside at the Royal Australian Navy’s Fleet Base East, in Woolloomooloo, which is known as Garden Island.
Check out the aerial photos.
THIS MEDIA RELEASE WAS DISTRIBUTED BY CSIRO, IMOS AND THE MNF ON FRIDAY 15 MAY 2015.
Researchers head to the seas off the east coast of Australia today on Australia’s new Marine National Facility research vessel, Investigator, to put in place ongoing measurements to track the vast volumes of water that influence our weather and climate.
“The East Australian Current sets the whole structure of the Tasman Sea,” CSIRO scientist and voyage leader Dr Bernadette Sloyan said.
“It influences our climate, the ecosystem, commercial and recreational fishing, much of what we see on the coast.
“If the current wasn’t there, we’d have a very different Tasman Sea.”
Dr Sloyan said the current was also a key component of global ocean circulation, moving heat, freshwater and nutrients around the South Pacific.
It moves massive amounts of water – each second transporting more than 25 million cubic metres of water, or 10,000 Olympic swimming pools, southwards.
“The voyage will deploy six large moorings, from the continental slope to the deep ocean off Brisbane,” Dr Sloyan said.
“This is where the East Australian Current approaches its maximum strength and its flow is relatively uniform so we can measure the current’s average flow and how it varies over time.”
The collaboration between CSIRO, the Marine National Facility and the Integrated Marine Observing System (IMOS) will enable the maintenance of multi-year monitoring of the current.
“The East Australian Current shows variations over a range of timescales from seasonal to decadal,” IMOS Director Tim Moltmann said.
“Much of what we know about the current has come from irregularly distributed observations collected over many decades.
“What is lacking is a sustained time-series of observations of the East Australian Current across its entire extent and of sufficient duration to understand seasonal, interannnual and decadal signals.
“The IMOS observations will provide significant new insights into the variable nature of the East Australian Current.”
Dr Sloyan said the current had important implications for Australia’s weather and climate.
“It is the dominant mechanism for the redistribution of tropical Pacific Ocean heat between the ocean and atmosphere in the Australian region,” she said.The waters in the Tasman Sea have warmed by more than 2oC, faster than other parts of the world’s oceans.
“Western boundary current regions, such as the EAC system, are highly variable and linked to large-scale ocean changes,” Dr Sloyan said.
“Monitoring the EAC therefore, provides information of the large-scale drivers of regional ocean change. These changes may result in subtropical marine species moving into temperate waters, altering the habitat of many species.”
Investigator is a 93.9 metre purpose-built research vessel, capable of travelling 10,000 nm in a single voyage, carrying up to 40 scientists and support staff, from the equator to the Antarctic ice-edge. The Marine National Facility is a blue-water research capability funded by the Australian Government. Under direction of an independent Steering Committee, it is owned and operated by CSIRO on behalf of the nation.
Over the past few months we’ve been working on an incredible virtual tour of the Marine National Facility research vessel, Investigator and it’s now ready for you.
Why don’t you come on board and run up and down the corridors, walk up the gangway, poke your nose into the fridge and see what’s for breakfast, sneak into the off limits area for the drop keels, check out the cabins, laboratories, the bridge… and… and… and…
It’s so awesome, you might never want to leave!

So what happened on the benthic trial voyage on board RV Investigator?
Tim O’Hara from Museum Victoria has written a fabulous blog about his experiences and you should check it out!
We’re looking for your feedback on how often the Marine National Facility calls for applications for sea time.
Over the years we’ve been listening to what you’ve been saying regarding how often the MNF calls for applications and in early February the MNF Steering Committee met and came up with two proposals.
We’d like you to read the discussion paper and let us know by 1600 AEST Thursday 14 May 2015 what you think.
Get to it, your contribution matters!
RV Investigator has been south of Tasmania with a huge team of biologists from around Australia, on the benthic biology trial voyage.
The aim of the voyage was to test the sampling equipment used by benthic scientists and to develop safe handling procedures. Benthic marine science refers to being on and just below the seafloor.
On board were scientists from CSIRO, Museum Victoria, the Australian Museum, the University of Western Sydney, South Australia Museum and the University of Tasmania.
It was an exciting voyage where the weird and wonderful things that live in our oceans were collected from the sea floor and brought on board to be studied.
The words hairy scary, ooey gooey, creepy crawly, blimely slimy come to mind!
