Researchers from five countries are using new technology to track and learn more about the Southern Ocean's blue whales.
Accurate scale replicas of Arctic ice floes are the centrepiece of a new exhibition at the Architectural Association in London.ScanLAB scientists measured real floes in the Fram Strait, northwest of Svalbard, Norway using millimetre-perfect 3D-scanning technology.
The completed digital survey model was then used to guide a Computer Numerical Control machine which carved the moulds, which are then filled with seawater and frozen.
Greenpeace scientists have used the data recorded by the scanning to measure the speed at which floes are melting in the Arctic, while the scale models - which melt slowly before your eyes - provide a stunning visual display for visitors to the gallery. William Trossell and Matthew Shaw of ScanLAB gave BBC news a tour of the exhibition.

Humans are causing a sharp decline in the populations of reef sharks in the Pacific Ocean, according to a new study by an international group of marine scientists.The new estimates compare the numbers of reef sharks around the islands populated with living near the uninhabited islands. The results are alarming, researchers say.
"We estimate that the number of reef sharks has fallen considerably around the populated islands, usually over 90% compared to those living in the most pristine reefs," said author Marc Nadon of the Joint Institute for Marine and Atmospheric Research, University of Hawaii.
More than 1,600 underwater surveys conducted in 46 Pacific islands and atolls in the U.S. were conducted for the study and were combined with data on human population, habitat complexity, the size of the reefs and the satellite record.
The estimates were obtained using "drag dive" where divers reported sightings of sharks while being towed behind a small boat. A method that provides a more accurate census of mobile reef fish, including sharks in large areas, the researchers said.
"Around each of the densely populated areas we studied, in the main Hawaiian Islands, the archipelago of the Marianas and American Samoa, the number of reef sharks was very low compared to the reef in the same regions that were simply further away from human beings, "said Nadon.
The study co-author Julia Baum of the University of Victoria in Canada asserts that human disturbance on reef shark populations are probably due to fishing, either catches in the nets of commercial fishermen or recreational, or direct attacks for their fins.
"The reef shark fins are the most valuable, as they tend to be smaller than other sharks, but a lot of other oceanic sharks have declined greatly, so that's why fishermen are turning to them "said Baum.
It is estimated that these fins are sold around $ 100 per kilogram with a demand from Asian markets, where is shark fin soup that is on the menu for weddings and business banquets.
The reef sharks, which are about 1.8 to 2.4 meters long, are "predators" of coral reefs Baum says, and like other predators in ecosystems play an important role in structuring food webs. But there is still much to learn about their specific role.
"Frankly, we are still trying to figure out what the predators on the reefs. The reason for this is because most predators have been removed from the reefs.
A pod of orcas, or killer whales, cooperate to wash a Weddell seal off an ice floe. This sequence, filmed for Frozen Planet, marks the first complete filming of killer whale "wave washing" behavior.
'The Bloop is the name given to an ultra-low frequency and extremely powerful underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) several times during 1997. According to the NOAA description, it "rises rapidly in frequency over about one minute and was of sufficient amplitude to be heard on multiple sensors, at a range of over 5,000 km. The source of the sound remains unknown...''
''Scientists determined that its wave pattern indicates it was made by an animal, and not a giant electromagnet sucking a plane out of the sky, as the creators of Lost were no doubt hoping.''
''While the audio profile of the bloop does resemble that of a living creature, the system identified it as unknown because it was far too loud for that to have been the case: it was several times louder than the loudest known biological sound.''
''There is no animal big enough or loud enough to make that kind of noise, not by a long shot. Not a blue whale, not a howler monkey, not a startled teenage girl.''

Recently Mike Martin, experienced a first in his 20-years of fishing, when he caught a giant goldfish in Lake St. Clair near Detroit, Michigan. Martin said, "We see them all the time but, to actually catch them is rare." Normally, the angler takes trips to the lake to catch perch, so when he reeled in a 3-pound, nearly 15-inch long goldfish, he was shocked.
The typical pet fish are said to grow much larger when given room to grow and not restricted to confined spaces. Martin said, "This will probably be the only one I ever catch so he's going to go on the wall."
Giant cannibal shrimp are invading the coasts of America en masse — and while it sounds like the work of a mad scientist in one of those cheesy, low-budget, black-and-white 1950s science-fiction movies, the danger (or rather, lack thereof) is all too real.
U.S. Geological Survey (USGS) and National Oceanic and Atmospheric Administration (NOAA) researchers have discovered that there were more than 10 times as many sightings of Asian tiger shrimp, which can grow to be more than a foot long and can consume their smaller relatives, off the Atlantic and Gulf of Mexico coasts in the US in 2011 than there were in 2010, CNN's Brad Lendon reported on Thursday.
"We can confirm there was nearly a tenfold jump in reports of Asian tiger shrimp in 2011," USGS Biologist Pam Fuller, the head of the agency's Nonindigenous Aquatic Species database, said in a statement. "And they are probably even more prevalent than reports suggest, because the more fisherman and other locals become accustomed to seeing them, the less likely they are to report them."
Researchers from the USGS and the NOAA are reportedly working with various state agencies to examine this phenomenon and discover what the massive influx of this decapod species, which is indigenous to the Indo-Pacific, Asian and Australian regions, means for native types of shrimp.
The cause of the increase in sightings is unclear, Fuller said, and scientists with the two agencies are hoping to discover more about the biology of the Asian tiger shrimp and the possible impact they will have on the coastal ecosystems in the US.

During a July 2011 voyage to the Pacific Ocean's Mariana Trench, the deepest region on the planet, Scripps researchers and National Geographic engineers deployed untethered free-falling/ascending landers equipped with digital video and lights to search the largely unexplored region.
The team documented the deepest known existence of xenophyophores, single-celled animals exclusively found in deep-sea environments. Xenophyophores are noteworthy for their size, with individual cells often exceeding 10 centimeters (4 inches), their extreme abundance on the seafloor and their role as hosts for a variety of organisms.

Clinging with root-like "rhizoids" to the soft, muddy sediment, the harp sponge captures tiny animals that are swept into its branches by deep-sea currents. Typically, sponges feed by straining bacteria and bits of organic material from the seawater they filter through their bodies.
However, carnivorous harp sponges snare their prey—tiny crustaceans—with barbed hooks that cover the sponge's branching limbs. Once the harp sponge has its prey in its clutches, it envelops the animal in a thin membrane, and then slowly begins to digest it.
The harp sponge's unusual shape and exposure to currents may also help it to reproduce more effectively. The swollen balls at the tip of the sponge's upright branches produce packets of sperm. These sperm packets are released into passing currents and are captured on the branches of other nearby sponges.
The sperm then works its way from the packets into the host sponge to fertilize its eggs. As the fertilized eggs mature, these contact sites swell up, forming bulges part way up the host sponge's branches

Models posed in their swimwear and accessories next to the world's biggest fish in the Philippines for an unusual fashion photo shoot to raise awareness about poaching of whale sharks.In a one-of-a-kind photo shoot, models Hannah Fraser and Roberta Mancino swam underwater with 30-foot-long whale sharks in Oslob in the Philippines.
Photographer Kristian Schmidt followed the models under the sea to capture the images, which had been four months in the planning.As well as capturing extraordinary photographs, the shoot also aimed to raise awareness about the plight of the whale sharks which are often the victims of poaching.
The photographers tracked the whale sharks down by tapping the knowledge of locals in the Philippines, who have developed a bond with the whale sharks.The local fishermen often feed the whale sharks in shallow waters with handfuls of shrimp, meaning that they were able to attract the fish to the photographers' location.

Found underwater pyramids and "Washington Monument" at the bottom of the ocean, close to New Jersey,
Armed with patience and a program GOOGLE EARTH6, Frank Martin Salish (FM Salichs) found interesting objects on the seabed. Besides the pyramids, Frank identified obelisk resembling the famous Washington Monument, but exceeds the size of religious buildings of the U.S. capital (height Washington Monument is 169 feet). The rounded shape and some details of the base indicate that the needle may be artificial.
"In the study of the oceans with GOOGLE EARTH6 I found the 640-foot obelisk in the form of a tower. It is located about 120 ml of the coast of New Jersey. Located on a very large plane, without a number of other structures within a mile, building higher than the Washington Monument , which has a height of 555.5 feet.
On the east side of the base can be seen clearly square regions with very long, straight lines and right angles, leaving from fundameta. The lower eastern part of the base has a large circular hole, it seems that it has been hollowed. The tower has a cylindrical shape and is just as high mahogany, with a narrow peak. 10 km to the east of the obelisk is 3 pyramids and 14 km to the west near the continental shelf are dozens and dozens of pyramids.
They are highly visible and easy to identify satellite images GOOGLE EARTH6. I'm currently working on a large video and pictures of these places and soon present them for viewing. In the meantime, I want to acquaint you with the details of the obelisk.
A huge pod of about 1,000 Common Dolphins stampeded off the coast of Dana Point, California, like a herd of wild horses. This has happened twice recently though it is very rare. The line of wild dolphins could be seen from miles away churning up the water and, to the delight of whale watching passengers and crew aboard Captain Dave's Dolphin and Whale Safari, the dolphins turned and stampeded directly over to the boat. Often this unusual behavior happens without warning or anything frightening them as was the case this time.
Ecstatic passengers aboard Captain Dave's Dolphin and Whale Safari were able to see the spectacular show from a unique perspective too: below the surface from the Eye to Eye Underwater Viewing Pods! In the two Underwater Viewing Pods passengers are able to BE one of the pod and feel what's it like to swim with wild dolphins without having to get wet.
Dana Point is in Southern California which has the greatest density of oceanic dolphins per square mile of anywhere in the world. This includes nearly 450,000 common dolphins like the ones in this video. Porpoising is their fastest mode of travel as there is less resistance in air than water. Dolphins are here throughout the year, sometimes in herds numbering upwards of 10,000.
In addition to incredible dolphins, Dolphin Safari whale watchers met several gray whales making their annual migration to Baja, California. At one point the herd of stampeding dolphins adjusted their course and headed right at the gray whales! Don't worry for the whales though, they avoided the dolphins who were of no threat and are continuing their journey south.
Explorer Mike Horn and Photographer Chase Jarvis encounter a rare "super-pod" of dolphins off the coast of South Africa. Thousands and thousands of dolphins give Chase and crew a mind-blowing photo and video opportunity.
The video of the giant squid was shot at a depth of 630 meters (2,067 feet) in the sea near the Ogasawara islands.Japan's National Science Museum succeeded in filming the deep-sea creature in its natural habitat for the first time, working with Japanese public broadcaster NHK and the US Discovery Channel.
They spotted the squid at a depth of 2,067 feet using a submersible in July, some nine miles east of Chichi island in the north Pacific Ocean.The submarine with three people on board, including Tsunemi Kubodera from the museum, followed the enormous mollusc to a depth of 2,950ft (900 metres) as it swam into the ocean abyss.
NHK showed footage of the silver-coloured creature, which had huge black eyes, as it swam against the current, holding a bait squid in its arms against the backdrop of dark oceanic depths.The creature was about three metres long, but "estimated to be as long as eight metres if its two long arms had not been chopped off", Mr Kubodera said.He gave no explanation for its missing arms.He said it was the first video footage of a live giant squid in its natural habitat -- the depths of the sea where there is little oxygen.
Mr Kobudera, a squid specialist, also filmed what he says was the first live video footage of a giant squid in 2006 but only from his boat after it was hooked and brought up to the surface.
The giant squid, "Architeuthis" to scientists, is sometimes described as one of the last mysteries of the ocean, being part of a world so hostile to humans that it has been little explored.
Scientists have captured footage of an elusive giant squid measuring up to eight meters. Seen on NHK channel from Japan in collaboration with the Japan's National Science Museum and Discovery Channel.

The earth planet shouldn't be called earth, it should be called planet ocean. Oceans cover approximately 75% of the world's surface and without them the earth would die. The oceans sustain the life on this planet and are essential to our health.
The health of our oceans is being compromised by accelerated human disturbances such as over fishing, pollution, global warming and other environmental factors making the health of our oceans a very serious cause for concern.

Seventy-five percent of Steller Sea Lions have vanished in the North Pacific. Now, a team of researchers near Vancouver, British Columbia, is working with trained sea lions to figure out why the population is in such steep decline.
A keen birdwatcher at first thought he was watching a dog struggling to escape from floodwater in a Cambridgeshire field, but on closer inspection he realised it was a seal making its way through the flooded field 50 miles from the nearest coastline.
Robjn filmed the seal's efforts to get out of the ditch close to the Great Ouse River, near St Ives in the Cambridgeshire Fens. He said it was not the first time a seal had been spotted away from its natural habitat but this one had made it ten miles further inland than previous incidents.
