Shipwreck Coast
Investigating Marine and National Parks
What you do
Go to http://www.parkweb.vic.gov.au/education/marine-mapping/Vic_MNP-map.htm
Hold the curser over the left rectangle on the orange map of the Victorian coast, this will bring up a yellow map os the shipwreck coast.
Move the curser down and click on the name Merri MS. This will bring up a short movie on the Marine National Park and Sanctuary
Then do the same for The Arches and The Twelve Apostles.
List as many words as you can to describe the Weedy Seadragon, our Victorian
marine state emblem.
(before doing so read about them at:http://www.parkweb.vic.gov.au/education/factfiles/07.htm
)
Use the dictionary to find the meaning of: maritime, plankton, lee, starboard, mollusc,
mariner, pelagic.
Write a 3-line Haiku poem about the sea using the format- line 1 has 5 syllables describing “where”- line 2 has 7 syllables describing “what”- line 3 has 5 syllables describing “how”
(eg.In the kelp forest
Dragons drift gracefully byWhile kelp sways gently)
Whale News!Baby whales are born underwater. Soon after, they are taken to thesurface to breathe and seek out their mother to drink from hernipple. The milk is very rich and helps the young calf grow quickly.When born, the Blue Whale weighs over 2 1/2 tonnes and is about 6- 7 metres long.
Whale TravelMost whales migrate longdistances each year insummer to the Arctic andAntarctic. In winter theyreturn to warmer waters, likethose around Australia, togive birth. They eat very littleduring their migration towarmer waters and tend todraw nourishment from theirblubber (fat around theirbodies).
Let's wail togetherWhales have been swimming in our oceans for twenty-five million years. It's a sad thingindeed that in the last 150 years whalers have brought them to the verge of extinction.
Park WhalesLast winter Southern RightWhales were spotted in theseas next to Port CampbellNational Park. Many differentwhales have been sightedand sometimes stranded onthe coast of Victoria. Watchcarefully for whales next timeyou visit the beach.

Make a Paper Whale
1. Fold A & B to the centre line.
Open up.
2. Turn paper round and repeat. 3. Fold along dotted line
so that flap sticks up.
Repeat on other side.
4. Fold
down flaps
and turn
over.
5. Fold back E & F to centre
line, but slightly below centre
of the paper. Cut along centre
line as shown. Fold the bottom
corner over towards the
middle. Fold the body in half
along the centre line.
6. Fold back the flipper on each side along the
dotted line. Fold the tail upwards along the
dotted line. Open the tail flukes.
7. Draw in the mouth and eyes.
Activity: A Virtual Transect
Background: When conducting surveys scientists use long lines called transects that cross through an area and provide a reference point along which observations can be recorded.
• In underwater surveys in water divers use transect lines to find out about marine habitats. Where water is too deep or difficult for divers to visit, video cameras are towed behind a boat and the data collected is later analysed to work out what is found in an area. Scientists are interested to know what material is found on the sea floor and what changes in the type of habitats are found in different areas.
Activity: A Virtual Transect Objective: You will conduct an underwater survey of a park by
analysing a section of towed video footage collected in a section of Point Addis Marine National Park.
Method: • Watch the video clip (
http://www.parkweb.vic.gov.au/education/marine-mapping/act03/act03-01.htm) several times to get a sense of the changes that occur in this section of the Marine National Park
• Using the distance information provided with the video clip use the table to record any changes that are observed in the type of materials that occur on the sea floor. Record these as sand or rock on the table.
• Repeat the clip and this time observe where kelp (brown seaweeds) occur and record this on the table.
• Repeat the clip again and this time make note of any sponge habitats that are found along the bottom.
• Finally record the presence of large groups of fish or other animals.
Activity: A Virtual Transect
Use these symbols to complete the table above: R (rock ) S (Sand) + (present) - (not present)

Animals seen
Record your results in the table below:
If you were asked to show this information with a drawing or chart rather than a table what would it look like? What shapes and symbols would you use? Give it a go.
What if your survey found other things on the sea bed? What shapes and symbols would you use for shipwrecks or dangerous rocks?
Living Between theTides (1)…Why are Victoria’s rocky shores special?
More than 95% of the animals and plants in our southernwaters are not found elsewhere on our planet. This includes
many of the sea stars, molluscs, crustaceans and othercreatures.
The shoreline area between the high and low tide is known asthe "intertidal area". This is an extremely challenging habitatfor survival and is in a state of constant change. As the tide
moves up and down, animals and plants must cope withproblems like drying out, waves, and the presence of many
predators. Only creatures that are well suited to thesechanges can survive here.
Rocky shores are an especially important type of intertidalarea. The rocks provide something solid for plants and
animals to hold on to and also can provide some protectionfrom changes in the environment and predators. As a result
rocky shores are rich in plant and animal diversity.
Living Between theTides (2)…Victoria’s Marine National Parks and Marine Sanctuaries.
Victoria is the first place in the world to establish a system of highly protected Marine National Parks and Marine Sanctuaries. 13 large Marine National Parks and 11 smaller Marine Sanctuaries are located across the state’s coastline and provide
protection of examples of our marine and coastal biodiversity.
Like our wonderful system of National Parks on land, our new Marine National Parks and Marine Sanctuaries protect all animals and plants within them from being removed or
killed.Marine National Parks and Marine Sanctuaries are also places for people. These areas
are important for scientific research, education, conservation, recreation and tourism, and fisheries management.
Recreational activities that are compatible with long term marine conservation such as snorkelling, diving, and photography are encouraged.
Marine National Parks and Marine Sanctuaries are fully protected. You may not fish, or remove animals, plants or artefacts such as shells, rocks, sand, and items of
maritime or indigenous value.
Living Between theTides (3)…Caring for the Coast and You
Even though the animals and plants of the rocky shore can cope with
difficult conditions, they still need to be treated with care. By adopting the
following behaviours you will help protect our fragile shore life while also
looking after yourself.
Caring for the Coast:
Enjoy exploring the rocky shore with care but leave the creatures where they are.
Handling may harm them and you.Always return any organisms or rocks you
may have disturbed to their original locations.
Keep marine animals and plants moist and cool when observing them by holding them
under waterStick to established paths to get down to
the rocky shorePlease observe and obey any signage on
siteTread lightly and try to walk or stand on
patches of sand or bare rock to avoid trampling rocky shore life
Please take your rubbish home – rubbish can harm birds and marine animals
Do not feed birds, seals, or other marine life
Keep clear of seals and bird nesting or roosting areas
Personal Care:
• Watch where your hands are going at all times to avoid
potentially dangerous creatures like the blue ringed octopus
• Wear sturdy shoes that grip well when walking on rock platforms to
avoid slipping and cuts• Never turn your back on the sea and be alert for large unexpected
waves at all times• Stay away from cliff edges and
bases• Check tide times when exploring
so you won’t be caught out• Be sun smart and use
sunscreen, a hat and suitable clothing to protect from the suns
damaging rays!
Write a letter to the Premier of Victoria telling him why Marine National Parks are important and what you think of them. Be as convincing as you can.
(Before doing so read about national parks at:http://www.parkweb.vic.gov.au/education/factfiles/26.htm
http://www.parkweb.vic.gov.au/education/factfiles/24.htm )
Design and make a series of signs to place around one of our Marine
National Parks orMarine Sanctuaries informing
people of its protected status and advising them what
they should do to care for it.
