In 1864 the French author, Jules Verne, published his novel “Journey To The Interior of the Earth”. In this book 3 men explore volcanic tunnels that lead miles beneath the Earth’s surface, and have a number of strange encounters along the way. One of these is the discovery of a massive ocean, deep underground. Now, 150 years later, it seems that Monsieur Verne’s imagination may have been more accurate than he knew.
An enormous reservoir of water, roughly 3 times bigger than all of the Earth’s oceans put together, has been detected 400 miles below the surface. The water is trapped inside a layer of blue rock called ringwoodite, in the layer of hot rock between the Earth’s core and its surface) that is known as the mantle.
Sitting back, ready for another interesting and rather aggressive night on COD (Call of Duty), I launch my dashboard to see the usual suspects all gathered playing the latest shoot ’em ups.
Except one. Looking again, I notice my 13-year-old brother Jimbob is playing a game I’ve never seen – MINECRAFT.
After much persuasion and explanation “COME ON BRO, BUY IT PLEASE, YOU BUILD STUFF”, I decide to purchase it, in order to support him in our mum’s campaign to play online more responsibly.
The game launches and all I see is blocks. Have I got the right game? Where are the graphics?
Wandering mindlessly around, past trees, rivers and spiders, until Harvey Jimbob asks me to come to his house. Here’s the strangest part: he built it.
Although beaches are fun places they can also be dangerous, and you may have heard some stories in the news lately about people getting into difficulties when they’re in or by the sea. Our science editor Sam Gouldson, who lives on the Sussex coast, shares her tips for beach safety.
Go to a Beach with Lifeguards
Many beaches have lifeguards, who are trained to keep people safe whether they’re on the beach or in the sea. You can find out where these beaches are by searching the Good Beach Guide (for the UK), Irish Water Safety (for Ireland) or the ILSE (for Europe). Find out more about the RNLI Lifeguards in UK here.
Pay Attention to the Flags
Beaches in the UK use a flag system to inform you of possible hazards. If there are red and yellow flags this means that there are lifeguards in that area and that it’s safe to swim.
A black and white chequered flag means that the area is for people using paddleboards, surfboards and kayaks, and that you should not swim there.
A red flag means that the area is dangerous and you should not go into the water for any reason. There may also be information boards and signs at the beach, and you should read these thoroughly.
Stay With Your Group
If you stick with your family or friends you can all keep an eye on each other. Find somewhere distinctive to use as a base while you’re at the beach and agree where you’ll meet up if you get separated.
If there are younger children in your group make sure they’re with a responsible adult or older teen. Some beaches have a wristband scheme so that children can be easily identified and their group members contacted if they wander off; if the beach you’re visiting has one of these schemes, take part.
Learn About the Sea
Different beaches have different conditions. The tide can come in much faster at one beach than at another, and you should always keep an eye on the water and which direction it’s flowing in. You can look up tide tables online so that you’re aware of when the tide is likely to turn and don’t get cut off from the shore.
Some beaches have dangerous features called rip tides, which are strong currents that can quickly sweep you out to sea without warning. Always check with the beach’s lifeguards if there are any areas that you should avoid – many beaches have a noticeboard to inform visitors about the current conditions.
Waves can also be dangerous, depending on how fast the water is moving and how steeply the beach shelves. Some beaches will have sharp rocks or other hazards that may not be clearly visible from the shore. Again, check the lifeguard’s advice before you go into the water.
If the weather is cool, consider wearing a protective suit to keep you warm in the water, as cold water shock can affect your breathing, blood pressure and heart rate.
Be Careful When Using Inflatables
Inflatable toys and beds are designed to be used in swimming pools, not on open water. But if you do use them make sure there is an adult with you and that you’re in the lifeguarded area between the red and yellow flags.
You should stay near the shore and never use inflatables when there are big waves or an windsock is flying; these are signs that the wind is too strong.
Know What to Do If You Get Into Trouble
If you find yourself in difficulties, stay calm. If the water is shallow enough for you to stand, wade through the water instead of trying to swim in it. Raise at least one hand in the air and shout loudly and clearly for help, and don’t try to swim against the tide because you’ll just tire yourself out.
If you have a board or an inflatable hold onto it; not only will it help you stay afloat it will also make you easier for rescuers to spot.
If you see someone who is in trouble in the water, stay calm. Alert the lifeguards, or if you can’t see them call the emergency services on 999 (in the UK) or 112 (anywhere in Europe).
Stay Safe in the Sun
Although the sea can be dangerous, so too can the sun. Always use sunscreen with a sun protection factor (SPF) of at least 30, and re-apply frequently.
Keep your head and shoulders covered, wear sunglasses to protect your eyes and stay in the shade at the hottest part of the day (usually between 11am and 3pm).
In our series of Great Women You Should Know … here comes daredevil and adventurer Betty Skelton
When she was eight, Betty fell in love with aeroplanes. She watched them flying over her house every day, she devoured books about them, and she begged her parents to take her to airfields where she would persuade pilots to take her on rides above the clouds.
Betty must have been a very persuasive person, because she also talked a young Navy pilot into giving the whole family flying lessons. And when I say whole family, I mean it: Betty flew her first plane solo when she was just twelve years old. She might have been a tiny daredevil, but she was so scared her mother would scold her for doing it that she kept it a secret for a week!
