Under the Sea with the RRS Discovery

Last month the The RRS Discovery, the most advanced research ship was launched in Southampton.
At £75 million it is one of the most expensive research ships ever commissioned. It measures at  just over 100 metres long, with seven main laboratories and a bridge like the Starship Enterprise! It has just begun expeditions around the British Isles, currently examining the UK’s continental shelf, a band of sea floor around 50m-100m deep.

“These shelves are really very important,” says Dr Sanders from the National Oceanography Centre in Southampton. “There is a lot going on in the shelf seas and we need to understand how they work so we can safeguard their future.”

Fact or Fable? Most body heat is lost through the head

Many people believe that you should keep your head covered during cold weather, as most body heat is lost through the head. It’s certainly true that any part of your body that’s exposed to cooler air will lose warmth; heat always moves from something warm to something cooler (that’s called the second law of thermodynamics). And our heads and faces are more sensitive to changes in temperature than other parts of the body.
