Goodbye from Heron Island
Three weeks on Heron Island has come and gone.
Samples are being packed away and diving gear is being aired out.
This was CReefs Australia's second trip to Heron Island giving the team
a second chance to collect samples from the reefs.
It was also a second opportunity to discover new species, proving that
even in an area where thousands of tourists dive each year, there is still
so much left to discover and describe.

During this trip the Autonomous Reef Monitoring Structures were
retrieved, uncovering a new genus of squat lobster, with more discoveries
expected.
The team of scientists and support crew worked long and hard – often
late into the night with early starts the next day – but also knew how to
relax.
It became an evening tradition to head down to the pier to watch the
sunset and chat about the day's work.
Phil Bock continued his field trip tradition of keeping everyone well
caffeinated and Francois Michonneau took charge of the whiteboard, while
Aaron Anderson, a man of his word, will be fondly remembered for his
budgie smugglers.
Damien Tosh kept us well-fed and happy with his delicious meals.
Now it's time for everyone to head back to their home institutions and
start work analysing the specimens they collected during this expedition.
Until next year. farewell from Heron Island. See you at Ningaloo in
May.

Behind the scenes
"Behind every great man is a great woman", or so the saying goes.
But definitely, behind every great field trip is a great support crew.
The three-week stay on Heron Island would not happen without the
dedicated work of the CReefs Australia support crew who keep the
scientists equipped and fed.
Heading the support crew list is Dr Julian Caley, AIMS Principal
Research Scientist, Principal Investigator of the global CReefs Project,
and leader of these expeditions.
Not far behind is CReefs Australia Field Project Manager Shawn Smith,
who not only plans the entire expedition – booking flights and organising
equipment and supplies – his skills extend to making hand mixers out of
power drills and cable ties.
Is there anything this man can't do?

Damien" Gastronomic taxonomist" Tosh has delivered amazing gourmet
meals night after night. Together with Aaron "Moustachio "Anderson the
pair have been the social glue on the island.
A born entertainer, Aaron has demonstrated his extensive knowledge of
marine life at the research station’s touch tank as well as his boating
and diving experience as one of the expedition’s coxswains.
The other coxswain, Stuart Kininmonth, joins the team from the
Australian Institute of Marine Science, as does Postdoctoral Research
Fellow Camille Mellin. Both are assisting with boating, diving and other
research tasks.
And then there's me, the excursion's blogger. After a couple of weeks
with the team of scientists I have a few new words to add to my vocabulary
and a new appreciation of the work of taxonomists.

Hard work and dedication pays off
What do you imagine is a typical day for a marine biologist out in the
field?
On Heron Island, the expeditioners wake up at the crack of dawn to
prepare for their morning dives. Convening at the boat shed, the gear is
packed and the boats lowered into the water before they set off for the
morning's location, whether it be Sykes Reef, Wistari Reef, the channel,
or some other location.
|
After a morning spent diving to collect samples the boats return in
time for lunch, sometimes quite a late lunch. Then it's back to the
lab where the eager group of taxonomists spends their afternoon
sorting and processing the samples.
Field work of this nature is a rare opportunity for most, who work
late into the night to ensure they don't fall behind in their
processing.
Senior Principal Research Scientist at the Australian Museum in
Sydney, Pat Hutchings, said her time on the island with co-worker
Postdoctoral Researcher Maria Capa was short so they intended to make
the most of it.
"Our strategy was to work long and hard for as long as we could,"
Pat said.
So too was the strategy of Florida Museum of Natural History PhD
student Seabird McKeon.
"These opportunities are rare so we make the most of it," he said.
But it's not all work and no play. |

University of California scientist Laetitia Plaisance, who is based at
the Smithsonian Institution in Washington, said she enjoyed the
friendly atmosphere of the CReefs Australia trips as the team talked
freely about their work. The friendly nature of the CReefs Australia
team even extends to sharing samples and helping their fellow
taxonomists search for species during dives. |

New genus found in Autonomous Reef Monitoring Structure
Specially designed mini-habitats retrieved last week from the ocean
floor have uncovered a new genus of squat lobster.
Kareen Schnabel, Collection Manager of New Zealand's National Institute
of Water and Atmospheric Research made the exciting discovery, with more
new species expected to be discovered.
The new genus was sampled for the first time from one of nine
Autonomous Reef Monitoring Structures (ARMS) deployed on the reef
surrounding Heron Island during last year's September CReefs Australia
expedition and retrieved last week.
The ARMS, consisting of a series of stacked plastic layers, are
designed to mimic a reef environment, allowing sea creatures to take up
residence inside.
|
Laetitia Plaisance, of the Smithsonian Institution in Washington DC
and involved in the international ARMS project, said the devices were
designed and developed by CReefs scientists as a standardised method
for comparing localities and to monitor biodiversity over time. The
CReefs Australia team has begun processing species samples collected
from the ARMS but Laetitia said it would take time before more
discoveries were made.
Once back in Washington, Laetitia will begin DNA barcoding the
contents of the ARMS collected during this field trip.
"My job is only just starting," she said. |

Autonomous Reef Monitoring Structures.

More than 300 ARMS have been deployed in locations around the world,
with almost 40 retrieved so far, including nine from Lizard Island in
February this year and nine from Heron Island last week.
Once the worldwide data is collected and processed, Laetitia said a
better estimate of marine biodiversity could be calculated.
"Because so little of the world's oceans have been explored – less than
5 per cent – the current estimate of marine life biodiversity stands at
between one and 10 million species."
The data will also provide marine scientists with a better
understanding of the human impact on marine environments, Laetitia said.
"At the moment we have no idea how much the biodiversity of a coral
reef is reduced by disturbances."

Magic carpet brings worms to the surface
CReefs Australia's polychaete biologists are using an unusual method to
collect samples.
Known as the "magic carpet" technique, a small plastic tarp is secured
to the ocean floor with a heavy chain to cut off oxygen to the area
underneath by preventing water flow.
|

Senior Principal Research Scientist at the Australian Museum in Sydney,
Pat Hutchings, said the area of ocean floor selected for the technique
"looked like a desert" when snorkelled over, but the sediment contained
animals beneath the surface.
"The theory is that you reduce the oxygen content of the sediments,
bringing all the animals to the surface," Pat said.
Some hours later, the plastic sheet is carefully peeled back and the
animals at the surface of the sediment are gently gathered into a catch
bag.
Polychaete consultant Lynda Avery, an associate at the Museum of
Victoria, said the polychaete species collected were then divided up into
taxonomic families and sent off to members of the polychaete team to
examine.
From the polychaetes collected from the magic carpet laid during this
field trip, Lynda is studying Opheliids;Senior Principal Research
Scientist at the Australian Museum in Sydney, Pat Hutchings, is examining
Terebellidae and Museum and Art Gallery of the Northern Territory Chris
Glasby is examining Nereididae. Polychaete expert Charlotte Watson, also
of the Museum and Art Gallery of the Northern Territory, is assisting the
team.
Lynda said the method had produced "very good" results when used during
a CReefs Australia field trip to Ningaloo in May, but this time had not
worked as effectively.
"But we'll wait and see the final results," she said.
Lynda also used the traditional method of collecting by "grab" nearby
to the magic carpet site in order to gather a different set of samples and
allow her to compare the results of the two collection methods.

BHP Billiton employees get involved
Usually desk-bound, Sjaak Lemmens has been getting a lot of hands-on
experience this past week.
An environmental advisor from Perth, Sjaak joined the Heron Island
expedition as part of the BHP Billiton Employee Engagement Program, which
sends two employees on each of the CReefs expeditions to show them
first-hand the kind of scientific work that goes on.
An experienced diver and former marine biologist with 30 years
experience, Sjaak spent a lot of time in the water during his stay.
He assisted with the retrieval of the Autonomous Reef Monitoring
Structures and helped some of the biologists collect samples.
|
Sjaak said he put his hand up to join the trip because he wanted the
opportunity to get involved.
"This was very much the kind of work I used to do," he said.
Sjaak left this afternoon after seven days on the island, and was
replaced by, Mark Hammond, another environmental advisor with BHP Billiton
Mark will pick up where Sjaak left off, assisting the CReefs team where
needed – and fitting in some snorkeling whenever he can.
Based in Moranbah, Queensland, Mark said he hoped to learn more about
marine taxonomy as well as help out the scientists where needed.
He said the mine he worked at was within the Great Barrier Reef
catchment and he hoped to gain a better understanding of how his
day-to-day activities could impact the reef.
Sjaak said he was sad to leave the island and had enjoyed his time with
the CReefs Australia team.
"I've been impressed by the level of dedication here. There's a great
team spirit," he said.

New squat lobster genus discovered
A new genus of squat lobster has been found off the southern coast of
Heron Island.
The tiny creature, barely half a centimetre long, was collected from
one of the Autonomous Reef Monitoring Structures(ARMS).
The ARMS were installed during last year's Heron Island expedition and
retrieved last week.
|
Kareen Schnabel, the Collection Manager at New Zealand's National
Institute of Water and Atmospheric Research Invertebrate Collection, made
the exciting discovery when she was able to identify the family the squat
lobster belonged to but not the genus.
She will now describe and name the new genus.
"I've named species before but I've never named a genus," she said.
Kareen said the shape of the creature’s rostrum, the patterns she
observed on the carapace and its claws were distinctly different from
other genera in this group.
She said squat lobster research had previously focused on deep-water
environments greater than 100m and there was a lack of collections and
knowledge of shallow water fauna.
"Shallow water fauna hasn’t been very well described in the South-West
Pacific, and this is something I would like to concentrate on in the
future," she said.

Squat lobsters are a diverse group of crustaceans commonly found in the
deep sea, with a total of about 900 species worldwide.

Taxonomy misunderstood and unrecognised
As much as two-thirds of marine life remains undiscovered – and this is
particularly true for the Australian tropics – yet the work of scientists
seeking out new species and describing them is often misunderstood and
unrecognised, says a senior scientist at Sydney's Australian Museum.
Senior Principal Research Scientist Pat Hutchings said taxonomy – the
practice and science of classification – struggled to gain funding from
major granting bodies and suffered a shortage of skilled taxonomists.
|
She said universities did not always expose their students to the
fieldwork that often inspired young marine taxonomists.
For young career scientists who do gain a passion for this branch of
science, Dr Hutchings said career opportunities were linked to funding.
"Although the Australian Museum is currently recruiting, there are very
few positions available nationally," she said.
Senior Curator at the Museum of Tropical Queensland (Queensland
Museum), Niel Bruce said taxonomy also faced the hurdle of not being
regarded as a serious science.
"Some of the other scientists in other disciplines don't see it as a
science but as a service, perhaps not realising just how much remains
unknown," Dr Bruce said.
"Yet everything we do as biologists is underpinned by sound taxonomy."
Despite these hurdles, Dr Bruce said BHP Billiton’s funding of the
CReefs Australia project and Australia Biological Resources Study funding
had made it possible for experienced and student taxonomists to expand
their research of coral reefs, considered to be the most diverse of all
marine ecosystems. |

AIMS Principal Research Scientist and Principal Investigator of the
CReefs project, Dr Julian Caley, said a number of young scientists had
joined this year's Heron Island expedition and he was impressed by their
enthusiasm.
"They are like-minded, dedicated to their particular groups of interest
and willing to share their findings and enthusiasm leading to a real
synergy among the researchers," Dr Caley said.
He said the young scientists were proof there was a pool of talent
available to replace older scientists as they retired – so long as there
were jobs available to accommodate them.

Collaborations extend beyond Heron Island expedition
CReefs Australia has produced some invaluable international
collaborations.
The Ocean Genome Legacy, based in Massachusetts, United States, has
begun working with the Queensland Museum's Centre for Biodiversity to help
sequence its entire collection of octocorals.
In addition, the organisation is in the early stages of assisting the
museum's parasitologist, Tom Cribb, by extracting the DNA from an archival
collection of fish parasites stored in alcohol.
|
The partnerships are the result of both organisations’ direct
involvement in the CReefs Australia project.
OGL Staff Scientist Abby Fusaro said the organisation relied heavily
on the expert knowledge and collections from a network of
collaborators around the world.
"Engaging researchers who are knowledgeable about their taxa offers
us the expertise we can't do without," Abby said.
She is also assisting Australian Museum Senior Principal Research
Scientist Pat Hutchings and Postdoctoral Researcher Maria Capa in
defining the taxonomic relationships of polychaetes, and Melbourne
Museum Associate Professor Phil Bock in his identification of bryozoa.
She said the collaborations would assist in the collection of
molecular data.
"It's fun having your hands in everyone's work," she said.
Abby will return to the United States with around 900 species
samples, which she will further process before the data is registered
with the organisation's collection. |

Next year OGL will launch an online catalogue of its collection, making
sequence data publicly available and providing access to DNA extracts for
scientific research.
