Good evening and welcome to the sunniest March Newsround for a

blooming long time! Yep, I'm Ricky and she's Hayley and here's what's

coming up: I'll have the low-down on the sunny weather and how long

it's going to last. And we will be telling you about what happened

here. But first, he may be the man behind

Hollywood blockbusters Avatar and Titanic but film director, James

Cameron, has reached new heights, or rather depths with his latest

venture. Yes we've been telling you about his plan to take a one-man

sub to the deepest point in the ocean and poke around in one of the

most secret parts of the planet. And he's done it! Take a look.

Pilot coming out! No wonder he's happy, Hollywood film director,

James Cameron, has just returned from the deepest part of the

world's ocean. Challenger Deep. Challenger Deep is in the huge

Mariana trench at the bottom of the Pacific Ocean, about 200 miles

South West of the island of Guam. It's nearly 11,000 metres deep.

That's the same as stacking 115 Big Bens on top of each other - that's

a lot of Big Bens! It took James Cameron and his special one-man sub,

Deepsea Challenger, two hours to reach the bottom. Man it's a long

way down, when you go past Titanic, then you got past Bismarck, then go

past where the mirrors can go and still only halfway there, two

thirds of the way there. travelling so far underwater can be

dangerous. This is only the second time a manned craft has explored

these dark depths, the first time was over 50 years ago. The weight

of all the water on top of him puts his sub under a lot of pressure.

It's like feeling the weight of a small family car resting on your

fingernail. Never nice. The Hollywood director is a bit of a

submarine geek and has taken the plunge for a new 3D documentary.

His sub was kitted out with all sort of hi-tech lights and cameras

but it's not clear what he was expecting to find during his three

hours on the ocean floor. Sunlight can't reach past depths of 1000

metres, so it's very dark but he might have seen a few of these

prawn-like amphipods down there at the bottom. But whatever he's seen,

his images of the ocean floor should be incredible viewing. But

don't expect to see Kate and Leo acting their way around Challenger

Deep anytime soon. I love you, Jack. The sun's shining - more on that

later. So time for a bit of cricket and in the opening day of their

two-test series, Sri Lanka have kept England on their toes. England

started well, taking eight quick wickets but an amazing unbeaten 168

from Mahela Jayawardene, means Sri Lanka are now on 289-8.

Three people have had to be rescued from a hot air balloon after they

accidentally flew it straight into power lines and got tangled up. The

balloonists were left dangling for five hours while the electricity

was turned off. No-one was hurt in the accident in Northamptonshire.

Now you may have noticed it's been a bit warm recently. Oh yes, it's

felt like a little bit of summer has landed in March. It's about

twice the temperature it usually would be at this time of year and

in Scotland they had the hottest March day on record yesterday.

So is this warm spell good news and will it last? I've been back to my

lovely Blackpool to find out Most of the country was bathed in

sun this weekend from the South of England to the north of Scotland

where records for March have been smashed! In Aberdeenshire, it

topped 22.8 degrees Celsius yesterday! These are the type of

temperatures we'd expect in the summer but it's still March and

this weekend the weather was hotter in the UK than it was in Barcelona

in Spain! And so many people have been making the most of it. It has

been really nice because you get to play out more and do more stuff

than in winter. You can do more stuff outside. You can play

football and rugby. If it was raining, you cannot play it. And it

has been very sweaty, to heart. Well, you can stay playing outside

for a bit longer boys as these summer temperatures are expected to

continue. Temperatures will stay warm for the next few days but be

cooler by Thursday. By the weekend we will see the last of it.

Temperatures will be where they should be for the time of the year.

But in some parts of the country the hot weather is causing problems.

Reservoirs in the south east of England are so empty there'll be

hosepipe bans from the beginning of next month. But here in Blackpool

the weather is good news all round! Joe here has sold ten times as many

ice creams as usual and there have been more people enjoying the

tourist attractions. But next week the weather will probably be back

to normal March temperatures, so I'm going to make the most of it

while I can. Tough assignment that, Hayley!

We've been asking you what you've been making of the hot weather.

Natasha, from Swindon, says: And Archie, from London, has joined

lots of others at the beach. He A Japanese fishing boat that swept

away in last year's devastating tsunami has been spotted off the

west coast of Canada. It's drifted without a crew for almost 4,500

miles across the sea and was spotted by coastguards, who'll

follow it to make sure it doesn't get in the way of other ships.

Millions of tonnes of debris will reach land eventually but this is

by far the largest bit found so far. Kids across the UK have been

learning more about the lives of children in Africa with the help of

a charity called 'SOS Children'. They've helped orphans film and

write about their everyday lives and post it online. And kids over

here have discovered that they've got a lot in common with young

people in Africa. What is great about Africa is you are learning

about children in Africa, what they have for breakfast, what they do in

their daily lives and what they like to do. They can relate to

children who are miles away from them.

Finally, what happens when thousands of Doctor Who fans all

head to Cardiff? You get the show's first ever official convention of

course! Fans have been meeting all the heroes and villains from the

show, plus Matt Smith and Karen Gillan even showed up!

That's it for now, but check out the website for a look at a new
