Ocean Alert: Overfishing
 
05:23
The world's oceans are the biggest source of food for the whole planet. Almost 35% of the world's population gets most of their protein from ocean animals. Although seafood markets around the market appear to be full, they hide a crisis: overfishing. Overfishing occurs when people catch more animals than the ocean can sustain.

Breathing under water is challenging. How does the oxygen uptake of cold-blooded, aquatic animals change as they grow? Both the capacity for oxygen uptake and the oxygen requirements of animals changes with body size. This animation explains how body size affects oxygen supply and demand via changes in surface area to volume ratios and viscosity effects to provide a better understanding of changes in respiratory challenges during growth.

How Temperature affects Growth
 
03:38
Can an oxygen perspective explain the effects of temperature on growth? Breathing under water is challenging, making it potentially difficult for ectotherms to meet their higher oxygen demand in warmer waters. This animation explains how an oxygen perspective helps to explain why temperature may differently affect small and large animals, providing an explanation for the temperature-size rule. In a previous animation we showed that the balance between oxygen supply and demand changes as animals grow (see http://www.youtube.com/watch?v=QCskh6NVa7U ).

► Adventure Ocean Quest - Fragile Mediterranean (FULL Documentary)
 
52:09
The Mediterranean Sea is a world of impressive diversity where ocean sunfish and whales live side by side, and colourful corals provide a home for smaller creatures. But human beings have left their mark here for thousands of years: ancient shipwrecks and fighter planes from the Second World War litter the ocean floor, while until recently raw sewage was fed straight into the sea. The impact has been devastating – today the Mediterranean is an ecosystem on the edge. But there is a glimmer of hope as measures to protect the sea from pollution and excessive disturbance are being put into place. Sandrine Ruiton from the University of Marseille specialises in research on artificial reefs to build up the lost marine biodiversity near cities like Marseille, one of the Mediterranean’s busiest ports. Until recently it was responsible for seriously polluting the surrounding Mediterranean Sea. Christian Petron himself has been instrumental in raising awareness of this ecosystem in dire straights. His own 30-year-old archive footage shows the extent of the pollution in graphic detail. Both Sandrine Ruiton and Christian are involved in the hugely successful ‘Prado Reef 2006’ project, which is designed to repopulate the local waters by encouraging the colonisation of new reefs. Even old shipwrecks and fighter planes turned into artificial reefs and first indications offer grounds for cautious optimism. But to be able to accurately assess the success of these artificial reefs, detailed population counts are absolutely essential. But their accuracy is questionable when carried out by divers with conventional equipment – reef creatures are notoriously shy and many are likely to hide at the approach of a noisy diver. So Sandrine Ruiton wants to find out if Frederic can achieve more accurate population counts on these fragile reefs by being less intrusive. His ability to move and behave almost like a fish without any cumbersome diving equipment allows him closer access without frightening the wildlife off. His first destination is the wreck of an freighter, sunk after world-war 2, closely followed and observed by Christian Petron. The collection of creatures found here are delicate and extremely cautious. But this dive also poses real challenges for Fred: diving in a wreck brings particular dangers with it, especially for a freediver. Nevertheless, he is determined to press on with his attempt to evaluate the state of Mediterranean marine wildlife. The artificial reef population surveys are only part of the reason why Frederic has come to the Mediterranean. He also works together with Dr. Pierre Chevaldonne, a scientist at the ‘Station Marine D’Endoume/Marseille’. Both are interested in an underwater cave that could be invaluable to modern science. Organisms and animals that are usually associated with much deeper waters thrive in this deep dark cave. In particular a collection of sponges could be of interest, not just because they provide an endless supply of biomarkers that are very sensitive to environmental changes: they are also highly relevant for modern medicine. Sponges are known to provide AZT (Azido-Thymidin) – currently one of the most used medications for the treatment of AIDS and in the fight against cancer. The sponges generate these substances as dangerous chemical weapons against predators or as a defence against harmful bacteria. The research team is renowned for their work on sponges, but the breathing bubbles emitted by conventional drivers would collect at the cave ceiling and gradually kill the cave dwellers. But Frederic’s approach is very different. By holding his breath, he can ensure that the sponges and other cave organisms are not threatened. He is able to explore the cave in detail and report his findings and bring samples back to the research group. This research can provide ground-breaking insights into modern medicine, as well as giving an indication of the health of the Mediterranean waters by examining the sponges’ biomarkers. Together, Frederic’s involvement in the artificial reef projects as well as the underwater cave exploration are extremely valuable contributions to the quest to document and protect the diversity of Mediterranean marine wildlife. He is in a unique position to access and approach the wildlife, that cannot be replicated by using conventional diving methods, and as such is an incredible opportunity for the scientists to gain a new window to the underwater life of the Mediterranean.

► Adventure Ocean Quest - The White Sharks of Guadalupe (FULL Documentary)
 
52:13
Up to 7 metres of muscle and teeth, packed into an agile and streamlined body that can weigh in at 2250kg – this is the great white shark, one of the most infamous hunters on Earth. But the reality is that these sharks may disappear from our oceans altogether within the next 20 years. Their terrifying reputation is part myth, part reality, rooted in their instinct to hunt and kill whatever looks like a good prey animal … and that can include human beings. But how far is their killer-reputation justified? Are great white sharks really the blood-thirsty loners we imagine them to be? Dr. Mauricio Hoyos is a scientist working on the behaviour and ecology of sharks. He wants to find out why they follow certain patterns of movements, including longdistance travels. The usual methods of getting close to great whites to study them closely and form impressions of their population cross-section include caged dives and diving with airtanks. But these techniques are now known to affect the sharks’ behaviour: the predators’ extraordinary electrical sensory systems react to the galvanic properties of metal. In addition, the sharks are often lured closer with bloody bait, a technique that undoubtedly increases the animals’ aggression and prey drive, which makes them uncomfortably dangerous diving partners. Furthermore, caged dives entirely rely on the animals coming to the researchers in order to take detailed notes on each individual, but the success of this depends on the sharks’ mood and willingness to approach the cage. Frederic is able to approach the animals and is treated entirely differently by them compared to conventional divers. His very basic equipment means that there is less chance of it interfering with the sharks’ normal and natural behaviour, which allows him to get close to them without triggering aggression. He dives with the sharks without a cage, without any form of protection – just Frederic and two other freedivers versus the predators in the water. They watch each other’s backs, because the sharks are known to attack mostly from behind. But freediving is the very thing that makes Frederic’s diving encounter with the great whites a safer experience. Frederic is likely to get much closer to the sharks than is normally possible, and in this way is able to assess the animals in more detail. Frederic’s assignment also includes an assessment of the sharks’ behaviour. This is also extremely difficult under normal conditions, when diving equipment interferes with the sharks’ behaviour. As such very little is known about the great whites’ detailed behaviour, and Frederic’s dives with them is an unprecedented window into their lives. Since Christian is there to document Frederic’s finding, the scientist is able to try to assess and interpret the behaviour witnessed by the freedivers. Since Great Whites have such a fearsome reputation, Frederic’s interactions with them in the water in itself provide the researchers with interesting insights into their interactions with humans. How and why does their behaviour differ towards a diver with conventional equipment compared to a freediver like Frederic and his two friends: This is an experiment that has never been documented before. To gain more insights into approaching fierce predators like the great white shark, Christian and Frederic have to be extremely well prepared. One thing is certain: with a predator like this, nothing can be left to chance. It is their success as a predator and their huge potential to inflict hideous damage that has made it so difficult to study them in detail and to assess their behaviour adequately from close quarters.

Marine ecology in easter island
 
03:39
Easter Island is the most isolated inhabited island in the world, over 3,000 kilometers from the Chilean coast. At about 29 degrees South, it is the southern limit to the range in which corals can thrive, and its extreme isolation has led to a depauperate marine community with extremely high endemism. However, whereas coral reefs around the world are currently in decline, reefs at Easter Island appear to have been increasing in coral cover for the last several decades from an algal-dominated state. Researchers from Chile and the US sought to determine how the small regional species pool and isolated oceanographic position of Easter Island might influence these changes.

Ghostly critters from the deep sea: Stygiomedusa gigantea
 
02:44
Stygiomedusa gigantea is one of the largest invertebrate predators known in the ocean, yet little is understood about its ecology and behavior. Stygiomedusa lacks tentacles, but has four extraordinarily large oral arms that are presumably used to envelope prey. The swimming bell of this spectacular medusa can reach over one meter across with arms over ten meters long. A symbiotic relationship between Stygiomedusa and the fish, Thalassobathia pelagica, was confirmed in 2003 when scientists from the Monterey Bay Aquarium Research Institute (MBARI) filmed the pair swimming together in the Gulf of California. The fish has adapted to using the medusa as a hiding place in its open ocean habitat. In twenty-seven years of scientific ROV surveys, researchers at MBARI have been lucky enough to observe this rare animal seven times, from depths of 750 meters down to 2187 meters.

Journal of Animal Ecology : In hot and cold water: differential life-history traits are key...

In hot and cold water: differential life-history traits are key to success in contrasting thermal deep-sea environments. Leigh Marsh et al (2015), Journal of Animal Ecology http://dx.doi.org/10.1111/1365-2656.12337 Few species of reptant decapod crustaceans thrive in the cold-stenothermal waters of the Southern Ocean. However, abundant populations of a new species of anomuran crab, Kiwa tyleri, occur at hydrothermal vent fields on the East Scotia Ridge. As a result of local thermal conditions at the vents, these crabs are not restricted by the physiological limits that otherwise exclude reptant decapods south of the polar front. We reveal the adult life history of this species by piecing together variation in microdistribution, body size frequency, sex ratio, and ovarian and embryonic development, which indicates a pattern in the distribution of female Kiwaidae in relation to their reproductive development. High-density ‘Kiwa’ assemblages observed in close proximity to sources of vent fluids are constrained by the thermal limit of elevated temperatures and the availability of resources for chemosynthetic nutrition. Although adult Kiwaidae depend on epibiotic chemosynthetic bacteria for nutrition, females move offsite after extrusion of their eggs to protect brooding embryos from the chemically harsh, thermally fluctuating vent environment. Consequently, brooding females in the periphery of the vent field are in turn restricted by low-temperature physiological boundaries of the deep-water Southern Ocean environment. Females have a high reproductive investment in few, large, yolky eggs, facilitating full lecithotrophy, with the release of larvae prolonged, and asynchronous. After embryos are released, larvae are reliant on locating isolated active areas of hydrothermal flow in order to settle and survive as chemosynthetic adults. Where the cold water restricts the ability of all adult stages to migrate over long distances, these low temperatures may facilitate the larvae in the location of vent sites by extending the larval development period through hypometabolism. These differential life-history adaptations to contrasting thermal environments lead to a disjunct life history among males and females of K. tyleri, which is key to their success in the Southern Ocean vent environment. We highlight the complexity in understanding the importance of life-history biology, in combination with environmental, ecological and physiological factors contributing to the overall global distribution of vent-endemic species.

Estuaries: Where the River Meets the Sea
 
02:01
Estuaries and their surrounding wetlands are bodies of water usually found where rivers meet the sea. Estuaries are home to unique plant and animal communities that have adapted to brackish water—a mixture of fresh water draining from the land and salty seawater. Estuaries are among the most productive ecosystems in the world. Many animals rely on estuaries for food, places to breed, and migration stopovers. Estuaries are delicate ecosystems. Congress created the National Estuarine Research Reserve System to protect more than one million acres of estuarine land and water. These estuarine reserves provide essential habitat for wildlife, offer educational opportunities for students, and serve as living laboratories for scientists.

Red Sea Coral Reef - Amazing World Under The Red Sea - History Channel HD Coral reefs are varied undersea ecological communities held with each other by calcium carbonate frameworks produced by corals. A lot of coral reefs are developed from stony reefs, which in turn consist of polyps that gather in groups. Unlike sea polyps, corals produce tough carbonate exoskeletons which support and safeguard the coral polyps. Frequently called "jungles of the sea", superficial coral reefs develop some of the most diverse environments on Earth. Paradoxically, coral reefs prosper even though they are surrounded by ocean waters that give couple of nutrients. They are most typically located at shallow depths in tropical waters, yet deep water as well as chilly water corals also already existing on smaller sized scales in other locations. Coral coral reefs are varied undersea ecosystems held with each other by calcium carbonate structures produced by corals. A lot of coral reefs are constructed from hostile reefs, which in turn consist of polyps that cluster in teams. Unlike sea anemones, corals secrete hard carbonate exoskeletons which support and protect the coral polyps.

Weird and wonderful deep-sea worms
 
03:31
Polychaete worms are common in the ocean. These worms have segmented bodies with paddle-like feet or parapodia on each segment. Most have bristles, or chaetae, that they use for defense, crawling, or swimming. Approximately 8,000 species have been described so far, but many new species are still being discovered. Some of the most beautiful and amazing polychaetes can be found in the midwater. In memory of Kristian Fauchald.

21:52
Tessa Danelesko, BSc is the coordinator for the B.C. Cetacean Sightings Network at the Vancouver Aquarium. She was raised in Calgary, Alberta and fell in love with the ocean during summer vacations while exploring the shores of Vancouver Island. She attended the University of Victoria and completed the Combined Biology and Psychology program. She has experience working and volunteering for a variety of marine conservation and research organizations that have taken her around the globe. About the Arctic Marine Life Course: Canada is an Arctic nation, yet only a small percentage of Canadians actually live in the Arctic. How do people living in the southern parts of Canada, or anywhere else in the world for that matter, learn about the unique and fascinating marine animals that inhabit this enigmatic environment? In collaboration with the Canadian Association of Science Centres (CASC) and the Canada's Accredited Zoos and Aquariums (CAZA), the Vancouver Aquarium Marine Science Centre is offering the Online Arctic Marine Life course to shed new light on this mysterious world! http://www.vanaqua.org/arctic-marine-life-course

Fluorescence in the deep-sea squid Histioteuthis: The case of the green-eyed squid
 
02:49
Scientists at MBARI recently deployed blue light-emitting diodes (LEDs) on our remotely operated submersibles to observe fluorescence in deep-sea animals and investigate the ecological roles of light in the deep sea. When we shined blue LEDs on the strawberry squid, Histioteuthis, we were surprised by an impressive light show. This squid has one normal-sized eye, and one extraordinarily large eye, which was brightly fluorescent, indicating the presence of a blue-absorbing fluorescent pigment. The fluorescent pigment most likely aids in capturing prey by breaking their camouflage. Many organisms have fluorescent structures, but we are still exploring what the natural functions of these fluorescent pigments are. For more information on fluorescence and bioluminescence go to http://biolum.eemb.ucsb.edu Video narration/animation/music/photos: Steve Haddock Video editing: Kyra Schlining Production support: Danielle Haddock, Linda Kuhnz, Lonny Lundsten, Nancy Jacobsen Stout, & Susan vonThun http://www.mbari.org
