How does water temperature affect the distribution of life in the oceans?

	In the first Blue Planet challenge, Journey to the Deep, you can explore some of the ocean's habitats and encounter an array of marine animals as you venture from a familiar rocky shoreline to the weird waters of the deepest abyss. You can find all the information you will need to complete the challenge in the dropdown fact files and infobursts.

	The Gulf Stream moves more 100 times as much water as all the rivers on earth at a speed of up to 97km (60 miles) per day. At its peak rate of flow, it can shift 90 million tonnes of water per second.
