WORK EXPEREINCE AT DPI QUEENSCLIFF

MDC Volunteer Lauren.D. reports on her work placement at DPI Queencliff...
As part of my university studies at Deakin University the unit Professional Practice requires the completion of 80hrs of work experience. I decided to undertake this placement at Queenscliff’s Department of Primary Industries in the Aquaculture department as I am very interested in this industry. Also, I was familiar with the area, projects and staff due to volunteering at the Marine Discovery Centre. This gave me a foot in the door to secure a work experience placement.

So far I am loving placement. I have gained huge amounts of industry knowledge and have met many interesting people. Two projects that I have participated in include the abalone offshore trials and the oyster hatchery.  Last Wednesday we induced spawning in the oysters. This was achieved by anaesthetising the oysters to extract larvae. In the end we obtained around 11 million larvae. It was amazing to be a part of and very interesting! I have also learnt huge amounts on the very successful mussel hatchery. I would definitely recommend the aquaculture department to others wishing to take part in placement – it’s awesome!

SUCKING SLURPING SEAHORSES

Seahorse feeding time with Georgie & Tess....

Seahorses are named for their equine profile. Although they are bony fish, they do not have scales, but rather a thin skin stretched over a series of bony plates arranged in rings throughout their body. Each species has a distinct number of rings.

Seahorses are ambush predators, feeding primarily on crustaceans, mostly shrimp. At the MDC the seahorses are fed a variety of foods: live amphiods, plankton but mostly brine shrimp.

Tap tap tap, this is how we get the
cheeky little shrimp out of the net

They swim very poorly by using a dorsal fin, which they rapidly flutter and pectoral fins, located behind their eyes, which they use to steer. Seahorses have no caudal fin. Since they are poor swimmers, they are most likely to be found resting, with their prehensile tails wound around a stationary object.

to grasp and/or hold objects.
They have long straw like snouts, which they use to suck up food, and eyes that can move independently of each other, much like a chameleon.

Clay-mation!

Today marked the beginning of a new technological revolution for arts and crafts at the Marine Discovery Centre with iPads being used for the first time!

On a busy Friday at the MDC, the kids came in droves to see not only the variety of marine wildlife on display but also to participate in the arts and crafts activities, including regular craftwork and then our new addition to the school holiday schedule - dubbed "Clay-mation."

Children were first given some brief instructions on how to use the new technology and were then paired up to create some awesome homemade marine based cinema using just plasticine and the iPads. Essentially, all it requires is the free app loaded onto the iPads, some coloured paper and tape to make a marine background stuck to the wall, and then some imagination and some clay to use it with!

The kids had a blast and soon we had some great videos to show for our newfound technology!



Luisa, Jordan and Ted with their Clay-mation plasticine models!


Each pair came up with their own individual motion capture story to tell and we had some great ideas including a surfing story, a beach scene, and even an Inter-tidal zone theme!

An Inter-tidal Zone movie in the making!

Surf's Up!
 

The kids hard at work directing their fishing video!


All in all, the new activity proved to be a big hit with the kids and is sure to be in the future as we continue to improve on our arts and crafts department for kids these holidays! Go MDC!

Videos of the children's creative motion capture stories are available for viewing at www.youtube.com/seaclaymation

Thanks Tim for your assisstance and great report. Today not only marked the beginning of iPads and clay-mation at the MDC but it was also Tim's first day as an MDC volunteer. What a blast!

Tuesdays with Peter.P

Long standing volunteer Peter.P tells us a bit about what he does during his volunteer time every Tuesday at the MDC...

I have been a senior volunteer at the Marine Discover Centre every Tuesday for the past 6 years. I began as an interpretive volunteer and eventually took on other responsibilities.
My daily duties consist of:
- Cleaning and tidying the Preparation Room.
- Compiling & maintaining an inventory of preparation supplies.
- Laboratory equipment maintenance.
- Ensuring that their are enough habitat series poster packs made up & beach combing poster rolled for all the school groups and other visitors to the MDC each week.
- I also compile a monthly newsletter for the Marine Discovery Centre. This contains some interesting articles I put together on local ecological and environmental issues. I also suggest ways in which we can mitigate pollution within our marine and freshwater habitats. These aquatic habitats support rich plant communities and incredible marine life.
- Whilst I do all these tasks with great pleasure my real passion remains for being an interpretive volunteer. Here I get to share my knowledge on Victoria's marine environment with MDC visitors. I usually talk about the importance of aquatic communities, the various aquatic habitats and how we should car for them. I discuss effective natural resource management with a focus on the effects of pollutants on fish populations.
I thoroughly enjoy my time as a volunteer at the MDC. All the staff and volunteers are really friendly, knowledgeable and share a passion for our marine environment. I find every volunteer day so interesting and valuable. The MDC is such an excellent centre for students and the general public to learn about Victoria's aquatic environments with a diverse array of habitats close by and the magnificent Swan Bay on its doorstep.  I look forward to continuing my role as an MDC volunteer for years to come.

Thanks Peter, you're a great help! We'll be sure to say g'day if we are ever in on a Tuesday!

There's something about Amy

Remember Amy? She worked as an Education Officer and Volunteer/Work Experience Coordinator for the MDC from November 2006 to February 2009 – after starting out as a grade 10 work experience student and subsequent volunteer for numerous years. Where in the world is she now? Just a week after finishing her contract with the MDC in Feb 2009, Amy was on a plane to move to Vancouver to start a new life with her long-distance boyfriend Darren and to continue her work in Marine Education... ahhh... the things we do for love...



AMY'S SNAPSHOT SINCE LEAVING THE MDC:

March - May 2009
Educator: 'Gently Down the Seymour'
Seymour Salmon Hatchery, BC,Canada 
 
From beach walks in the Australian summer to freezing cold days in many, many layers of warm clothing conducting education programs with primary school students that came to the hatchery (which was covered in 3 feet of snow!) to learn about Pacific Salmon life cycles, stream habitat surveys, forest ecology and freshwater invertebrate collection and identification.
 
May - September 2009
Interpreter
Vancouver Aquarium, BC, Canada
Working with the Interpretive Delivery Department at Vancouver Aquarium (not interpreting language, but rather the animals, their life history traits and conservation issues) this was Amy’s first experience conducting “shows” on microphone – from Beluga whales to hissing cockroaches!
 
September 2009 - present
Curriculum Programs Coordinator
Vancouver Aquarium, BC, Canada
Back in her element: the core of this role involves coordinating the Aquarium’s school programs and the volunteer educators who conduct the programs – Amy facilitates the field trips and leads the class’ education program, but the volunteers are the ones who do the bulk of the teaching for students in small groups of 5-8. The Aquarium offers over 20 different school programs each year from preschool to grade 12, with 150 volunteers to assist! Over the past 2 years Amy has focussed her niche within her team of 4 coordinators to proffessional development workshops and resources for teachers, supervising & mentoring student teachers, evaluation methods, customised education programs and improving marketting and communication methods internally and externally.
 
“I miss my MDC co-workers and volunteers… not to mention snorkelling and exploring sandy beaches! Hope to be back on Aussie soil in the near future! Thinking of you all and hoping you’re happy and well.” - Amy

Thanks Amy, we miss you too and enjoy hearing your lovely voice recording every time we call up the MDC office!

It's Science Week!


Three super sweet & friendly vols, Elly, Kirsten & Laura (aka the three musselteers), report on their time lending a hand at the MDC trailer during Living Science...


On Sunday the 14th of August the MDC participated in the first 2011 national science week event Living Science at the Queen Victoria Market. The event was all about exploring the science of food. There were plenty of activities for everybody to enjoy!

The focus of the MDC stand was the Mussel industry and how DPI are working to improve mussel farms in Port Phillip Bay. Samad is a researcher at DPI working on mussel farming and told us all about the interesting research he is working on to improve mussel stocks. The MDC trailer had lots of information and resources available about sustainable fishing, Port Philip Bay and of course the touch tank, which everyone loved.

We met Tubby the Robot, who provided lots of entertainment for the children...as well as us.



He even came with his own robot fish!
 
CSIRO had a demonstration on how to make your own sherbet, which tasted just like Wizz Fizz. All you need is: 1 teaspoon of sodium bicarbonate (baking powder), 1 teaspoon of citric acid and 6 teaspoons of icing sugar. Sift all the ingredients together and you have your very own sherbet. Pop it into your very own marine decorated paper bag to make the experience even better!

Here we are filling out some surveys about our Science Week experiences, we of course rated it very highly.




We got lollies to reward our efforts...

...and even a free pen!

Melbourne Uni had a really cool demonstration about the science of making chocolate. We didn’t realise there were so many steps involved in making chocolate. Roasted cocoa beans are very bitter and we much preferred tasting the final product.

We all had a great day at the market and learnt lots. We hope everyone who visited our stall, had a great experience and learnt all about the mussel industry, once they realised we weren’t actually selling mussels. Many people asked us if the mussel ropes on display were for sale. They weren’t!
 Yumo! Thanks ladies!

Whale watching in Port Philip Bay

Many of you will know Alan and Mary long-time volunteers and now occasional staff. A truly dynamic duo, Alan an underwater cinematographer extraordinaire and Mary a world renowned prestigious underwater photographer, wowzza!

Alan and Mary some how have an incredible knack of attracting envious and magic marine experiences. Some call them whale callers, some think they are really marine animals pretending to be humans, others think they are humans pretending to be marine animals… but here at the MDC we call them just damn lucky!

 

Over the last three weeks when the sun was shinning and the whales were calling, Alan and Mary headed out on their boat to scout Port Philip Bay for some of their marine mammal friends.

Low and behold each of the three weekends they went out they came across glorious Humpbacks off the Mornington Peninsular. Last Saturday they came across four males and one female off Mount Martha!

 



It appears that for the first time recorded in the bay these massive marine mammals are mating! Alan and Mary observed some battle wounds on the males who are busy fighting each other over the lone female. It appears that the barnacles present on their bodies are cutting into their skin as they push, shove and hit each other. Alan and Mary have been logging their observations with the Dolphin Research Institute and ensuring that their humpbacked friend don’t stray into the bays shipping channel, ensuring no large container ships cause any unnecessary harm.  

 

To view more of Mary’s photos visit her Marine Life Image Library. You may have already seen some of her photos in the media. Some of her pics of her humpbacked friends have recently featured in the Herald Sun.  

Alan and Mary truly are lucky ducks!

One very happy diver...

Our own little mermaid MDC junior volunteer Shari recently returned from a sweet dive trip up north. Here she shares her news and some of her incredible and award winning photo's with us. Massive congratulations and thank you Shari, very inspiring and very proud!

Shari aka MDC little mermaid

As some of you know I recently returned from a week long dive trip in Cairns. Being marine-y people, I thought you'd like to see some photos and have a re-cap!

Organised through my local dive shop, dad and I booked a week-long live aboard trip. For all those non-divers, a live aboard is just a trip on which you live aboard the boat for X amount of time!
We arrived in Cairns, greeted by other eager divers from the local club. After a night of heavy partying (for some), most of the dive crew were still asleep at 1pm when we got to the hotel. That day was spent shopping at different markets, finding amazing little tropical treasures. A quiet night ensued, as we were up early for transfer to the boat.

We arrived at the dock, and quickly boarded the amazing 120ft vessel 'The Spirit of Freedom'. Overcome by the sheer size and beauty of the boat, we were briefed on the sun deck before leaving port. We were headed about 200 miles North of Cairns on the Ribbon Reefs. That afternoon, we did 2 'intro' dives so the crew could get used to us and check out our dive styles. The dives weren't particularly excellent, but that seemed to be lead up to the next few days of diving. The first reef we visited was called Saxon reef, and we did our two dives at 'Turtle Bommie' and 'Coral Gardens'. (Unfortunately we didn't see any turtles on that dive!)


After each dive, the crew would quickly present us with piles of fresh fruit and light snacks to keep up our energy. Being the only vegetarian on board, I was quickly ridiculed by the more 'blokey' divers!
Dinnertime was light but filling, with a lovely tofu and mushroom stir-fry for me, and a critically endangered bluefin tuna steak for the rest (the irony!). We all seemed to sleep well that night, with lovely calm seas that seemed to rock us gently to sleep.


Heading out for a dive
My lovely dreams stopped abruptly at 6am, with the crew knocking at the door politely shouting "Dive time!!". In the space of 10 minutes, all the underwater creatures had climbed from their bunks with weary eyes, and were sitting with a small bowl of cereal. Within half an hour, we all had wetsuits on and were being briefed on our first 'real' dive. The cod hole!


Without much thought whatsoever, we leapt into the lovely 25 degree water and were immediately greeted by at least 3 giant potato cod. What a way to start a morning! The cod hole is a series of 'steps' that lead to around 40m, with 8m at shallow sandy coral gardens. It was an absolutely lovely dive, with jagged reef lining the sand which made up a hidden ecosystem of nudibranchs and clownfish. Our second dive was the cod feed, straight after our main breakfast (hash browns and fried things galore!).


At the feed, we knelt in a circle on the sandy, shallow bottom. Inevitably, this proved difficult since there was a slight current slowly tipping us all over. A crew member swum to the middle of the circle with a bucket of pilchards, and sat in the centre. We watched her swim to the first 'victim', and she would gesture the question 'Are you ready?' and if you nodded, she threw a pilchard right in front of your nose. Instantly, a 2m+ potato cod swept in, opened its massive mouth and just as it enveloped your entire face, it sucked the small fish in and swam off behind you. This dive was a truly amazing experience.. but this was nothing compared to what else we had in store!


Potato cods bigger than a sack of potatoes

The third dive for that day was at the Twin Towers. Oh my, such an amazing seascape! On a 30m reef, a huge rock structure spiralled beautifully up to two 8m pinnacles. Everyone started at the bottom to get some depth, before exploring the piles of coral and rocks. Caves were rutted out of the rock, which made homes for large white tip reef sharks and batfish. Looking closer revealed different species of nudibranchs, some only 3 millimetres long! In between the towers, a very friendly olive sea snake swam with us for a while, swirling in and out of my legs. It was hard not to handle it like my pet snakes at home!

On the outskirts of the towers, large pelagic barracuda circled in the blue water, and Spanish mackerel danced in the sunlight. It was hard to leave the site! But when it came time for our safety stop at 5 metres, we were met once again by the curious sea snake. He teased me for a few more minutes before going back to explore the peaks of the erupting monument. Whilst waiting for my dive computer to count down 5 minutes on the safety stop, dad and I played 'paper, scissors, rock'.

 I glanced behind him and out of the light blue ocean, I saw a glint of white off in the distance. I watched for a while longer, and before long it appeared again. This time though, I saw a goliath appear from the empty blue - a dwarf minke whale. We watched as long as we could, but soon had to surface because we were very close to running out of air.

Delightful dancing dwarf minke whale

We clambered back onto the boat and quickly stripped off our dive gear, ready to jump right back in! There was an ecstatic feeling in the air as all the divers rushed into the water as snorkelers; we swum out behind the dive deck and grabbed a line that had been tied to the stern. As soon as I looked down, I saw 3 dwarf minke whales 4 metres below me - absolutely amazing. As we each latched onto the line, the whales cruised past, looking at us. There were about 7, some with distinguishing markings, some more curious than others.

As people left the water, they seemed to become braver and venture closer and closer to us. The whales would just drift past, and wouldn't be seen again for 5 minutes or so. Suddenly they would all sweep in at once from different angles, and it was almost like they were dancing for us - a beautifully choreographed dance of curiosity and happiness, with each pass closer and closer. By the time we were the last few in the water, the whales were close enough to touch, almost inviting us to caress their large, soft bodies (but of course that was illegal!).
Absolutely stunning, it was just one mammal to another, accepting each other for simply being. A moment I will never, ever forget.


The fourth (and final) dive that day was at Challenger Bay. It was of course a lovely dive with numerous nudibranchs, and a highlight of juvenile lionfish and soft corals. Bright yellow trumpet fish gently fluttered past, creating the perfect evening/late afternoon dive. Later that day, a night dive at Challenger bay was optional, but I chose to sit out as I was quite water logged after being under all day!


Another early morning dive at Pixie Pinnacle - What can I say. A very impressive dive starting deep and spiralling up toward gardens of soft corals littered with lionfish and nudis, sea snakes and pipefish. The fish shoaling on the rock face, elegantly twisting and swimming in unison seemed to be in their own little grand ballroom. Words cannot express the beauty of these dives.


Lionfish at Pixie Pinnacle

When we arrived at our next dive site, whales had been spotted again! We either had the option to dive the site or snorkel with the whales, so I stripped off the camera strobes and went in snorkelling. There were only 2 other people in the water which made the second encounter even more calming. To my surprise, this was the same pod of whales that we had seen the day before!! I could see the older, more experienced one that came closer to us, and the quicker younger ones that hung deeper. It was amazing to have them swim straight for us, and then duck under the water before colliding and glide so easily underneath us, whilst we kicked and flopped on the surface like a fish would on land. The thing that set this apart from the previous encounter was the 'singing'; at one point, one of the whales hung below us and tipped it's head down - I had shivers down my spine as it begun to sing and make these wonderful, deep burping sounds. I just wish I could understand it!

Having to get out of the water and leave those wondrous whales for the last time was one of the hardest things I've had to do. It was so sad to have shared such a special moment with them, and just leave without saying goodbye and thanks!

Wondrous whales

Singing stars


Our second last stop was 'the Cathedral'. This beautiful dive was dominated by white spotted eagle rays and dozens of mobula rays (like a mini-manta ray!). Big coral and rock bommies pushed up from the ground formed big upwellings of small fish and plenty of soft coral. Turtles swum around and around, scouting the area, as larger pelagic fish drifted in the deep blue. This dive was a hotspot for the Dusky Nembrotha (I suggest you Google!). These are probably my favourite nudibranchs - black bodies with lime green spots and neon orange lining, such striking contrast!

Dusky Nembrotha

 Our last dive was a drift dive in the afternoon. It was at an aptly named Dynamite Pass. Our boat anchored in deeper water, and we had split up into 4 groups. Each group was taken out about 2kms by one of the on-board zodiacs, and dropped on the edge of a large wall. We all rolled back into the water at once and quickly descended. The wall was reef that was infused with sand - it really did look like the reef had been blown up, and sand was seeping out of the wounds. As the current pushed us, we went into the shallows and explored the maze-like shallows.


Imagine you're in sand shallows, 6m deep. You face a coral wall, with a metre wide crack down the centre. You swim through, carefully not to damage the large fans jutting out in front of you. As your round a corner, a whole new world opens up. An underwater garden of Eden with creatures that possibly haven't seen humans before. Holothuroids (my favourite!) are dotted across the sand and you watch as small damselfish come in and out of hiding in coral rubble.


Other divers soon joined dad and I, and we each explored these shallow gardens in our own way, each reminiscent of the trip and its ultimate beauty. I just lay on my back and looked up at the surface, watching the waves lapping softly, my bubbles climbing to meet the clouds. We were like children exploring a new place, as excited as could be, skittish and light-headed. Handstands and underwater fighting were just a way of expressing the sheer joy of being truly care free.


That evening our group sat on the top deck, watching the sun set, waiting for nothing. It was so beautiful and nostalgic, we were all completely speechless. We sat there, enjoying coronas, waiting for the night celebrations to start. And they did after the fourth round!


Soon after coming home, I entered 2 of my photographs into the 'Young' category in the Cairns Underwater Film Festival. I recently found out that I came runner up and winner for that bracket! Big thanks to Harbour Dive, the Spirit of Freedom Crew and my dive buddies for this truly unforgettable experience!!

An awesome crew and sweet dive buddies
Happy diving

Cute & sexy squid...

I would like to welcome our three new additions to the Marine Discovery Centre!  We now have three beautiful female dumpling squid to fill the empty blue ring tank.  However, they love to hide so I hope you enjoy the challenge of finding them!  And perhaps if you are lucky you will get to see them eat.  They are speedy and veracious predators, the little glass shrimp don’t stand a chance!

Sweet little dumplings, too cute for words.

These squid have been donated by myself (Amanda) as I am finishing up my research on the mating behaviour of these amazing animals.  These squid mate multiple times during their breeding season and each copulation can last up to two hours!  The mating begins quite viciously with the male quickly grabbing the female and then manoeuvring her into position.  He then pumps jets of water into her mantle cavity, presumably to remove sperm from previous matings, before transferring the spermatophore bundle.  The remainder of the two hours is required to complete the transfer and eversion of the spermatophores. 
Karma Seatra, how embarrassment!
My research involves investigating the costs of mating in this species.  These costs could include energetic costs, predation costs and lifetime costs.  I am currently submerged in statistics to try and determine which factors are actually significant.  So I will need to get back to you with the results!  I hope you all get a chance to come into the MDC and see these cute little critters!

Hide & seek little ticksters.
Epic photos Amanda! Many thanks, we all look forward to hearing your results & checking out these cuties in the MDC aquarium!
