NIWA -  a flashship

Artificially-  not true

Atmospheric - thing that keeps it up

High-resolution - good perfect

Examined by scientists - good scientists

Submersible - submerged

Enabled - blocked

Seabed - The bottom of the sea 

• How do the scientists study the reef? What are they trying to show or figure out?By diving and they are trying to discover If coral can survive was bad things in the water 
• Why are the NZ scientists testing in an "artificially acidified sea water" - what does this mean? They get a bucket and put some pollution in it and see if the coral can grow.

• Why does Australia have tropical coral and NZ have cold-water coral?Because New Zealand is not close to the equator and it is very cold.
• Where does NZ cold-water coral grow? How far down? Why can't NZ have tropical coral?Around New Zealand 2500 m down and it is too because it is too cold. 
• How do scientists get the cold water coral so they can study it? Because NZ corals only live in cold water 

• Make a DLO showing 'before and after' type photos of coral reefs. Make a screencast and explain how coral reefs are damaged using your own words.
• Before pollution the ocean looked very good but after the pollution started the corals started dieing

The great Barrier Reef 2

The Great Barrier Reef

Reef sharks- are sharks that live in the reff

Clams-very big clams

Cauliflower coral-corals that look like cauliflower

Snorkeling-Diving with a small tube

Staghorn coral- coral like sticks 

Clownfish- A very beautiful fish what yellow and orange

Vibrantly-Small sound wave

Ecosystem-Life

Greenhouse gas- bad gas

Acidification-dissolves water

Where is the Barrier Reef- the easten coast of Australia 

How long- 2900km

How is it made-It is made by the waves the waves created cracking rocks so the coral 

 can live in it then the fish live in the coral 

Name 10 animals that live their- corals, lobsters, clams, seahorses, sponges, sea turtles. clown fish. Angelfish, Reef sharks and Algae  

Why is it called a Tropical Reef- because it is warm and it is close to the equator. 

What temperature is the Great Barrier Reef- 23 degrees Celsius in Winter and 29 degrees Celsius in summer.

What is an ocean Acidification-Water is going too hot because the Carbon dioxide dissolves in the water and heats up. 

And why is it bad it is- fish dies and corals don't grow
