BBC Britain's Secret Seas (complete, 4 episodes - 2011):

BBC Britain's Secret Seas 1 of 4 Giants Of The West 2011:
In the first programme of the series, the team uncover the world of the giants 
that reside in and on our Western seas.

A few metres off the Cornish shore, the team study Britain\'s largest fish, the 
basking shark. Despite the fact that they grow up to ten metres long, little is
known about them, which makes effective conservation very difficult. In an 
exceptional encounter, the team are surrounded by up to twelve sharks as they 
feed on microscopic plankton.

Their shark expedition then takes them north to the Isle of Man. Working 
alongside local scientists, they take shark DNA samples using a kitchen scourer
in order to assess the genetic health and long-term fitness of these great 
leviathans. The team also run into a giant swarm of jellyfish.

In the waters of South Wales, Tooni encounters an invading army of giant spiny 
spider crabs. These creatures boast a leg span of over a metre across, and 
Tooni reveals that they come into the shallow waters every year to find a mate.

On Lundy Island off the Devon coast, Frank assesses whether the island\'s 
protected underwater No Take Zone could be used as a template to establish a 
nationwide network of marine nature reserves right around our island.

Frank also reveals how Great Britain still relies on the sea to import goods. 
He boards one of the biggest transatlantic container ships in the world, The 
Atlantic Companion, as the vast ship brings its cargo into Liverpool Docks.

In treacherous waters off the Isles of Scilly, Paul dives the largest shipwreck
in British waters to assess the legacy of the worst ecological disaster to 
affect our shores so far; the ill-fated Torrey Canyon oil tanker.

BBC Britain's Secret Seas 2 of 4 The Wild North 2011:
In the second programme in the series, explorer Paul Rose, marine biologist 
Tooni Mahto and maritime journalist Frank Pope explore the wild seas around 
Scotland.

The team travel to Bass Rock, one of the largest gannet colonies in the world. 
They are there to try and find out why when most British seabird populations 
are in decline, the northern gannet is bucking the trend. Tooni helps 
scientists who are using GPS trackers to discover the extraordinary distances 
gannets can fly in the search for food. Paul goes beneath the waves to witness
the amazing diving ability of Britain\'s largest seabird.

Tooni joins a scientist in St Andrews Bay in search of the bottlenose dolphin 
to find out why dolphins have unique signature whistles - could they be names 
as we know them? She also takes Paul on a spectacular night dive at St Abbs in
search of the amazing sea creatures that fluoresce beyond our visual spectrum.
And intriguingly, this discovery has been used to help study cancerous cells.

Expedition leader, Paul Rose, meets the hidden heroes of the Royal Navy. They 
are on a special clearance mission around Garvie Island at Cape Wrath. The Navy
divers go underwater clearing live 1,000lb unexploded bombs dropped by aircraft
during training exercises. These are modern and extremely powerful weapons that
must be detonated with explosives - underwater.

We have over 25,000 wrecks around the British Isles. These wrecks are a rich 
archaeological record of our maritime heritage, but sadly they are being 
damaged by trawlers, souvenir hunters and the forces of nature. Frank and Paul 
Rose go to the Sound of Mull, to see first-hand what can be done to preserve 
the history locked away in these relics.

BBC Britain's Secret Seas 3 of 4 The Power Of The East 2011:
This time on Britain\'s Secret Seas, the team set out to explore the waters off 
our eastern coastline, which are constantly pounded by the raw power of the 
waves. These are the shallowest waters off our shores but over the centuries 
they have been some of our most productive, providing oil and gas as well as 
fish for our tables. But things are changing in the North Sea and our team 
discover a sea full of surprises.

On the Farne Islands, they come face to face with England\'s largest colony of 
grey seals to find out what makes them such extraordinary divers and successful
hunters. Grey seals can dive for over forty minutes on a single breath - the 
team find out how they do it and why they seem to be coping with the changing 
conditions on the east coast far better than the harbour seal.

Elsewhere, Frank looks at the newest form of energy in the North Sea, at a wind
farm off the Norfolk coast, and Tooni examines what effect the wind turbines 
are having on marine life. Paul uncovers the intriguing history of light 
vessels among the sandbanks of the Thames Estuary; and Tooni gets to the bottom
of a bumper lobster harvest in the port of Bridlington.

Paul dives with a shoal of fish that soon transform into a school when he 
starts to behave as if he were a predator. To find out how they are able to 
achieve such synchronised motion and why they suddenly change direction, he 
joins a scientist who has created a plastic imposter - Robofish.

BBC Britain's Secret Seas 4 of 4 The Bustling South 2011:
In the final programme of the series, explorer Paul Rose, marine biologist 
Tooni Mahto and underwater archaeologist Frank Pope explore our busy southern 
shores.

As one of the world\'s busiest shipping lanes, our southern seas are littered 
with wrecks. Outside Poole harbour, the team join an archaeological excavation 
of a mysterious 17th century ship. Bearing incredibly ornate carvings of a 
merman, Frank reveals this is one of the most important underwater discoveries 
since the Mary Rose. Paul joins the dive team working on the wreck to try to 
discover where this ship came from. But it\'s a race against time as the timbers
are being destroyed; Tooni wants to find out why.

Frank and Tooni examine how we balance the needs of marine life with those of 
people when the two come into conflict. Studland Bay in Dorset is home to a 
thriving population of spiny seahorses living amongst the rare eelgrass beds. 
Only identified as breeding in the area seven years ago, the intensive use of 
the bay, illegal boat moorings and pleasure boats anchors are threatening to 
decimate the seahorses fragile eelgrass habitat.

Paul dives two wrecks in the search of the mighty conger eel to find out if, 
when he comes face to face with one, these incredible beasts will live up to 
their fearsome reputation.

As the tourists hit the roller coaster and dodgems on Brighton pier, they know 
little of the wonder beneath them. Tooni dives underneath Brighton pier to 
reveal one of the best places on the south coast to see a great variety of our 
native marine life.

Out in Lyme Bay, Frank dives the wreck of an experimental WWII submarine.
