Free diving Free diving is about not having tanks or air. The world record deepest free dive is 281m with fins. The longest time under water was over 11 min.
Submarines Submarines are basically are big tanks of air. They can go deeper than any divers. Periscopes let them see above the surface.
Tunnels under the sea The longest under water section is the Channel Tunnel connecting France and England. Some of the Cornish mines go right under the sea. Some people think there will be cities under the sea in the future.
Self contained under water breathing apparatus Scuba diving is a type of diving unlike free diving scuba diving you carry on your back a tank of air. Divers that go to deep could get the bends. If you get the bends you have to go in a special machine that takes away the bends, called a decompression chamber.
Where Under water volcanos happen where two plates meet under the sea. For example the ring of fire and Iceland.
What They are volcanos under the water.
Chimneys and life around Chimneys are under water volcanos they create spires of rock. They are some times called “black smokers”. Bacteria feeds on the chemicals coming out of the chimney. And the bacteria supports other life forms like shrimps. It can create ecosystems in the deep sea that would normally require sun light.
Why doesn’t the sea evaporate? Some of the sea does evaporate but is always replaced by rivers and rain so the ocean soaks up the heat.
Atolls Is the brim of a volcano and then coral grows on the brim. An atoll only happens in the tropics because coral only grows in the warm seas.
Conditions In shallow water it isn’t very compressed, but in deep water it is so compressed it is like having ten elephants on your back. The deeper you go the darker it gets, because the water above absorbs the light of the sun. Also the deeper you go the colder it gets until you get to a certain depth where it stays the same cold temperature.
How to get there To get there you might think is impossible but we have learned how to do it. The machine that is helping us to do it is called a submarine. A submarine is a big tank of air that protects humans from the water but if you want to go really deep you use a very strong submarine called a bathysphere.
James Cameron is a film director who recently went to the bottom of the Mariana Trench in a mini sub.
Animals Some animals in the deep sea are very strange, for example the Anglerfish has a light on its head to attract prey. There are more than just the Anglerfish, like the gulper eel and the Dragonfish . All these strange creatures have evolved to the deep sea so well they couldn’t survive in shallow water.
Today we went on a canoe trip, to go and see a giant sand dune. We had to row against the current and the wind on the way, and we got splashed a lot. On the way we found a tiny island and it was covered in cockles, so we got a few for dinner and we put them in the bottom of the canoe.
When we got up to where the giant sand dune was, the sand was very sticky and squidgy, so I ran around in circles and made a big trail of footprints so it looked like 10,000 people had stood there. We couldn’t go to the giant sand dune because it was a breeding pace for birds, but we still walked along the beach with the squelchy sand, and when the wind blew, all of the sand went along the ground and hurt our feet. When it got past you, you could see lines of sand blowing along in the wind.
We had lunch behind a sand dune and then we went back home. One the way back it was less splashy as we were going with the current, and hardly had to paddle at all.
When we got back we went for swim and drifted right round a catamaran and back to the beach.
One tree Hill is in the middle of the city of Auckland, in a park called Cornwall Park.
The funny thing about one tree hill is that at top there isn’t a tree, because some random guy chopped it down because it was an English tree, and when England came to invade New Zealand they planted that tree there on top of the hill because that random guy thought that the tree represented all the bad things that had been happening to New Zealand. So that random guy thought that he would chop it down with an axe.
One Tree Hill is also a place where they had a memorial for a Maori chief and in honour of the Maori people. One Tree Hill is also a volcano which could erupt at any second. When you are at the top you can see lots of other volcanoes in Auckland.
It is also a Maori hill so they lived there in little huts to defend from strangers. Now it is completely surrounded by the city of Auckland. Here is my video of One Tree Hill so you can see what it is like. I was born only a couple of miles from there.
Today is a very exciting day because we are going to Hobbition. But first we are going to the Buried Village.
We are staying in a holiday home with Aunty Jilly my Godmum and her dog named Jess. It is her birthday this week. The holiday home is by Lake Tarawera, which is next too a large volcano that has three craters. This volcano was the most recent large volcano eruption in New Zealand. It erupted in 1886 on June 10th.
When it erupted it buried the pink and white terraces. The pink and white terraces were layers and layers of rock created by the steaming geysers that lots of people used to visit. This was a real treasure to New Zealand and one of the eight wonders of the world.
The mud also buried a maori village. They dug it up with a spade and a brush so we could view it. We saw a secret passage way in one of the houses which went into the wall. There was also a sewing machine in a tree and a cannon which wasn’t called a cannon.
Sam and Anna at Bag End in Hobbiton
After that we went to Hobbition, which was in the middle of a sheep farm. First when we came in we saw a nice mans hobbit hole who had a grumpy wife, this is where Gandalf and Frodo first ride in on their carriage. And then lots of hobbits children come running up to Gandalf and begged him to do some magic and he makes some fireworks.
After that we walked into the main part of Hobbiton. Everything was grown naturally with no sprays and there was lots of vegetables which the hobbits plant, look after and eat. In reality there are 8 gardeners who do all this work and they don’t like to be called hobbits!
At the top of the hill was Bagend also known as Underhill, which is where Frodo and Bilbo live. It is the biggest hobbit hole.
The we walked down the hill and got to the party field and party tree and that is where Bilbo had his birthday party and he loved it.
At the end of our quest we went to the Green Dragon and had a nice glass of Ginger Beer and a muffin. I would like to live in Hobbiton and stay there forever.
Today we went to see steaming geysers and boiling mud pools at Rotorua. First we went to the Maori show, there were Maoris doing dances and had a spear called a Taiaha. The Taiaha was good for distracting, poking and whacking their enemies, and I got to hold one and chat to the warriors.
After that we went to see some Kiwis. When the female has the egg, the last week she can’t eat anything at all because the egg is too big in her tummy. So when she lays the egg she leaves home and she leaves all the work to the male. The male has to sit on the egg for the last 90 days.
Next we went to see a mud pool, which was all gloopy and smelly, and there were bubbles popping out of it. They were the gas leaving the mud from deep underground. Then we went to see the Geyser and it started erupting just as we got there. The water in the Geysers is steaming and boiling on the way up, but when it comes back down from the air it is cold again. The chemicals coming up from underground left colours everywhere, yellow, green and orange. And they stink.
This is a steaming geyser errupting
Next we went to a proper Maori village where they used to live. There were houses off the ground, and they had very small doors. They hang out fish to dry in the sun. They use the cooking pots and place layers and layers of food on top of each other. Then from underground the warmth cooks the food and then they just pick it up and eat it. They had a Maori canoe called a Whaka.
In the evening we got to go and see glow worms. They were just like little dots on the bank of the Williams’ lane, and you could poke your head through the bushes to see them. Some of them flashed and some were really bright. They were white.
