![]() Thousand (ppt) which is the typical unit for which salinity is ![]() Is much more salty and has on average ~3.5% salt content, also While fresh spring water and most lakes and rivers contain more dissolved salts (~0.02-0.4 Rain is essentially pure water (consisting only of H 2O with trace amounts of elements and other compounds picked up from atmospheric dust), This water comes in many forms, each with it's own special properties. Liquid water covers most of the surface of our planet. And only on such planets could life as we know it Only a planet of the right mass, chemical composition, and Nor has a drop of water been observed yet in interstellar No liquid water has been confirmed in our solar system, but it is likely that Jupiter's moon Europa and Saturn's moon Enceladus have liquid oceans under a frozen crust. However, liquid water is a rare commodity in our solar system. Water for granted after all, our bodies are mostly made of water. Planet Earth has been called the "Blue Planet"ĭue to the abundant water on its surface. ![]() What role does the ocean play in climate change? Hopefully, with more information on what we are doing to our planet we can find a way to change it and make it better.What is the composition and structure of the ocean? Not only does it show you the beauty hidden below the waters it is also shows how humans have ruined the seas and how we have killed off and eaten and hunted so many types of fish so much so that they are depleting fast. This documentary is one of my favourites but it is also heartbreaking too. Even going out on a jet ski in treacherous waters just to get some good shots of some dolphins seems like a crazy thing but these guys will happily do it. This one thing shows how much time and effort the team put into figuring things out for the show and how to get the best shots. ![]() One thing I loved was that they stuck a camera connected to a suction cup to a killer whale when it came up to the surface so they could really get into the action. How they filmed it and what lengths they went to. Especially the fish that, after a few years of being a woman, becomes a man to continue her genes – I couldn’t quite believe that one.īut the part I love most in these documentaries is the end where they show how they did it. The brain power of these animals is enormous! The amount of skill and evolution these things have gone through to become the beings they are today is so cool to see. To even the killer whales who use their tales to cause shock waves in the ocean to stun fish so they’re easier to eat. We get to be up close and personal with a range of ocean life including killer whales, dolphins, seals, walruses and even a fish with teeth! We get to see how these animals have adapted to be able to survive, calling back to the fish with teeth again, he is able to find clams and break them open on rocks to eat the insides. The first episode of Blue Planet II follows animals from Antartica to the tropical coral reefs. So move over lizard chasing snakes, it’s the walrus’ time! I think it’s the fact we don’t know much about it so there’s so much more to learn. David Attenborough is back! He is honestly one of my favourite presenters and although I love the Planet Earth documentaries there’s something so much more interesting about the ocean.
