The Deep Sea - Top 10 Facts
The deep sea is the largest habitat on the planet, taking up to 95% of the earth’s living space. Yet, the deep sea also the most unexplored environment, despite being one of the most amazing places on the planet. Throughout this video we’ll explain 10 amazing interesting facts about the deep sea.

Nobody knows where it begins - The ‘deep-sea’ is a contested term, lacking a single exact definition. For some it refers to the any part of the ocean where scary, odd and downright bizarre creatures live. For others, it’s a descriptive definition of specific ocean depths. Credit: http://linkbun.ch/04fay - Deep sea creatures are purposefully incredibly diverse. - Species from the deep may look like they’ve evolved in strange ways just to freak us out, but in fact they’ve evolved that way for specific survival purposes. For instance, to take advantage of the lack of light, most animals are transparent or red, a colour which few creatures can detect and is camouflaging in the darkness. Credit: http://linkbun.ch/04f2h - Exploring the deep is tremendously testing - An obvious fact, but one you probably haven’t seriously thought about. Part of the reason why it’s taken us so long to explore is because only recently have we created new generations of incredibly sophisticated underwater vehicles that are able to venture so deep. Credit: http://linkbun.ch/04f2i - Only three people have ever been to the deep sea - Due to the previously mentioned extremities, the deep sea may be the final frontier of exploration. Many more people have then been into space than to the deep sea. Like seriously, a loaaad more. Over 500 people have been into space, whereas only 3 people have ever ventured over 1000 fathoms into the depth of our oceans. Credit: http://linkbun.ch/04f2j - New species are being discovered daily - Since it’s largely unexplored, each time a vehicle is sent into the deep, it’s highly likely to unearth a new discovery. Over a recent year-long period the World Register of Marine Species reported discovering 1451 new marine species, of which many were found to be from the deep sea. Credit: http://linkbun.ch/04f2k - It’s a giant’s playground - The term Deep-sea gigantism exists in zoology for a reason. It refers to the tendency for deep-sea dwelling animals to be larger in size than their shallower-water relatives. We're not sure whether it comes about as a result of adaptation for scarce resources, greater pressure, or for other reasons. Credit: http://linkbun.ch/04f2l - Some amazing ecosystems exist on the ocean floor - In 1977 a deep-sea research expedition made history as they found hydrothermal vents releasing mineral rich water at the bottom of the ocean. Credit: http://linkbun.ch/04f2m - Geothermal vents aren’t the only thriving ecosystems on the ocean floor - Lush Deep-water coral gardens of various sizes, colours and shapes are able to survive in the Icy cold and extremely dim waters of up to 6000m (20,000 ft) below the ocean’s surface. In fact, scientists have discovered nearly as many species of deep-sea corals as shallow-water species. Unlike shallow-water corals, deep-sea corals don’t need sunlight but rather obtain the energy and nutrients they need to survive by trapping tiny organisms in passing currents. Credit: http://linkbun.ch/04f2n - The deep-sea may solve many of our problems - Some organisms that live in deep-sea coral habitats and the deep sea in general produce chemicals with enormous potential for future medicinal or commercial products such as pharmaceuticals, enzymes, pesticides or cosmetics. Credit: http://linkbun.ch/04f2o - The sea floor is a barren land - Put all your thoughts of geothermal vents and deep-sea coral reefs aside because the vast majority of the seafloor is featureless mud. On the face of it, it’s pretty similar to the empty expanses of outer space, but in space you can see everything using telescopes.

Living on the Ocean Floor
Living on the Ocean Floor - footage recorded by Vincent Zintzen, Te Papa Fish Team, Natural Environment. Film recorded using a baited Lander in various locations and depths around NZ. The video unit lights up the dark world of the deep sea. Food is scarce so the animals that live in the depths are attracted to the bait. The camera reveals the interesting behaviour of these creatures as they strive to survive in their extreme environment The footage of the seal shark attacking the hagfish, and getting a mouthful of slime for his troubles, is a good example of the knowledge gained through this difficult and exacting research.

Community Ecology: Feel the Love - Crash Course Ecology #4
Interactions between species are what define ecological communities, and community ecology studies these interactions anywhere they take place. Although interspecies interactions are mostly competitive, competition is pretty dangerous, so a lot of interactions are actually about side-stepping direct competition and instead finding ways to divvy up resources to let species get along.

Dokdo’s Rich Ecology
[Anchor Lead] Korea’s Dokdo Island is known as an ecological treasure trove home to many rare animals and plants. Korea’s easternmost islets are again drawing attention for ecological value, as rare aquatic species with unique appearances and names have been observed in the clean waters near the rocky outcroppings. [Pkg] Dokdo Island is situated in the middle of the vast blue ocean. It is an ecological treasure trove inhabited by roughly 590 species of animals and plants. A picturesque scene unfolds under the sea. Schools of fish in various colors swim about in leisure. A black sea bream, a native of Dokdo, takes a break between the rocks. Coral reefs, a resting place for fish, adorn the underwater world with splendid colors. In particular, the ocean beneath Dokdo Island is teeming with living organisms, because it is a place where warm and cold currents meet. Last year, the government discovered three unrecorded species, including paranamixis shrimp. Recently, an undocumented species of the moss fringehead, indigenous to Dokdo, was identified for the first time. Moss fringeheads, a fish in the order of perciformes, are characterized by cockscomb-like tentacles. The government has decided to name the species the Dokdo moss fringehead and register it in a list of aquatic organisms. [Soundbite] Ahn Yong-rak(National Marine Biodiversity Institute) : "Various marine creatures have been secured and the importance of Dokdo as a repository of maritime resources has been rediscovered." Dokdo, part of Korea's sovereign territory, is a rich repository of maritime resources. The continued discovery of new species presents valuable assets that prove the nation's biological sovereignty over the island.

13 Shocking Effects of Pollution
13 Very important and terrible effects of the pollution that us humans are creating from trash harming animals to noise pollution Subscribe to American Eye http://goo.gl/GBphkv 7. Acid Rain Acid rain can occur naturally from volcanic emissions but there is a direct result of human activities and acid rain. With toxic fumes getting mixed into clouds, they get absorbed into our atmosphere and can come out from rain. Animals and plants need a particular ph level in order to stay healthy... 6. Noise Pollution Effects Many of us might limit the idea of pollution only to nature and not sound. We are quite used to the sounds of urban life and it doesn’t begin to bother us. Whether it’s listening to music or pets barking, it might not be a serious issue. But when noise keeps us from going to sleep at night, it begins to turn into pollution. This normal infers to noises that are unnatural and excessive. This can actually lead to more problems than you’d like to think. Our ears were not constructed to handle the amount of noise that we might experience in the big cities of today. Loud noise can certainly lead to sleeping disorders and health issues as well. Studies show that aggressiveness can be a direct link to noise pollution. This affects other animals as well, especially since they rely heavily on sound in for things such as hunting and mating rituals. 5. Toxic Air Pollution Some places in China are experiencing record high levels of air pollution. It’s getting so rough out there that even dogs are wearing surgical masks to protect themselves from the toxic fumes. In 2015, 100 million people were warned and told to stay inside their houses across 10 different cities. Schools and factories were shut down, hoping to reduce exposure to the heavy blankets of toxic air swarming the country. Rising levels of air pollution have caused a new disease; called the Beijing Cough. This is from burning a large amount of petroleum in recent years. In the past, the air pollution from China has travelled to the Central Valley of California. A number of children suffer from respiratory illnesses and things don’t seem to be getting any better. Kids are more vulnerable to respiratory illnesses due to their size Living somewhere with a lot of pollution certainly makes it difficult for Santa Claus act jolly during Christmas time 4. Smog Smog is a direct result of air pollution and other places like LA There are several pollutants that make the sky murky. There’s particulate matter which includes smoke and is the main cause for smog. But there are other pollutants that are released which certainly don’t help. Other common air pollutants include Hydrocarbons, Sulfur Dioxides, and silent, invisible killer (carbon monoxide). Cars, and trucks also emit a large amount of smog. A simple way to reduce this is to participate in carpooling or taking public transportation. Each year, 50,000 or more people die in the US due to air pollution. 3. Trash Outweighing Fish It’s predicted that in the future, about 30 years from now if changes aren’t made, they’re will be more trash in Earth’s oceans. The amount of plastic waste is much higher than other type of trash that is found and is much more hazardous to our ecosystem. Much of this could simply be avoided by just recycling. The plastic is not only valuable to companies who want to use it, but quite important to keep out of our oceans. It takes one plastic water bottle, 450 years to biodegrade. Some bottles possibly 1000! Debris left over from fishing can be left in the ocean and harm seals like we see in this photo. 2. Fish Kills Another shocking effect of pollution is what’s known as a fish kill. This is when a large amount of fish show up dead and can be caused from numerous environmental factors. Although there are natural causes for this, things like toxicity, reduced levels of dissolved oxygen and drought are all possible ways. Agricultural pollutions with water rich in pesticides can often reach places where fish are present. If a chemical like cyanide is released into the water, people will be able to tell from the fish's gills turning a cherry red. The fish’s habitat is fairly fragile and any slight changes in chemical compounds can result in fish kills. 1. Global Warming With so much carbon and greenhouse gases being emitted into the air, where are they supposed to go? Our ozone layer which regulates our temperature, keeps gases from escaping. Temperatures changed and oceans are getting warmer and even slight changes can have dramatic consequences. Glaciers melting. Coral reefs disappearing, droughts, floods can all be a result of this. Let’s all do our part and keep mother earth alive and flourising… Before it’s too late.

Paludarium Ecosphere WITH FISH
I would never intentionally put fish in a sealed ecosphere like this, but since I accidentally caught one I might as well. TWITTER: https://twitter.com/HelloDustinDust EMAIL: [email protected] PAYPAL DONATIONS: [email protected] In this video I create a Paludarium, which combines aspects of an aquarium (water) and a terrarium (land) into a single display and can potentially host both land and aquatic animals. I'm taking things even further by completely sealing the paludarium off from the outside world inside an airtight container. The intent is to create a completely self sustained ecosystem that recycles nutrients and wastes in order to sustain life inside. The only external input is the solar energy from the sun, which keeps the entire system running.

Ecology: Oxygen & Growth of Aquatic cold blooded animals
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.

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.

Lost at sea: Ecological assessment around a sunken shipping container
Thousands of shipping containers are lost from cargo vessels each year. Many of these containers eventually sink to the deep seafloor. In 2004, researchers at the Monterey Bay Aquarium Research Institute (MBARI) discovered a lost shipping container almost 1,300 meters (4,200 feet) below the surface of the Monterey Bay National Marine Sanctuary. In the first ever survey of its kind, researchers from MBARI and the Sanctuary recently described how deep-sea animal communities on and around the container differed from those in surrounding areas. The red dots seen in some of the underwater footage are lasers mounted on the remotely operated submersible. The lasers are 29 cm apart and allow the scientists to estimate animal size.

Simple Animals: Sponges, Jellies, & Octopuses - Crash Course Biology #22
Hank introduces us to the "simplest" of the animals, complexity-wise: beginning with sponges (whose very inclusion in the list as "animals" has been called into question because they are so simple) and finishing with the most complex molluscs, octopuses and squid. We differentiate them by the number of tissue layers they have, and by the complexity of those layers.

Marine Pollution
The ocean covers almost three quarters of our planet. Populations in coastal regions are growing and placing increasing pressure on coastal and marine ecosystems. Marine pollution of many kinds threatens the health of the ocean and its living resources. While the past decades have seen efforts at the local, national, and international levels to address the problems of marine pollution, more needs to be done. Learn more about marine pollution at www.state.gov/ourocean.

Endangered Species: Worth Saving from Extinction?
Species are going extinct at crazy high rates. Does it matter? Find out in this video. SUBSCRIBE to Above the Noise: [https://www.youtube.com/abovethenoise...] ABOVE THE NOISE is a show that cuts through the hype and investigates the research behind controversial and trending topics in the news. Hosted by Myles Bess and Shirin Ghaffary. *NEW VIDEOS EVERY OTHER WEDNESDAY* What does it mean when a species goes extinct? A species goes extinct when there are no longer any more of that species left on earth. That species is gone forever aka extinct. What is the 6th mass extinction? Throughout earth’s history there have been five major mass extinction events-- where a large percentage of species died out. Scientists estimate that we are in the middle of the 6th mass extinction event right now, where species are dying out at 1,000 to 10,000 times baseline extinction rates. Why should we care if a species goes extinct? Moral and ethical arguments to try to prevent species extinction include reasons like all life has a right to be here, or that we owe it to our grandchildren to protect species so they can see them in the wild. Species also impact the ecosystems they are a part of; plants and animals depend on each other in an ecosystem for things like food and shelter, so if one species dies out, then that could affect other species in an ecosystem. For example sea otters live in kelp forests and eat sea urchins, and when they were hunted almost to extinction the sea urchin population increased and ate all the kelp-- destroying the kelp forest habitat. What are ecosystem services? Ecosystem services are the collective benefits we get from ecosystems. Ecosystems provide us with a lot of great things like natural resources and water, and are home to living things we depend on-- like insects that pollinate our crops and decomposers that get rid of our waste. Ecosystems are healthiest when they are the most biodiverse.

Symbiosis is close and often long-term interaction between different biological species. The definition of symbiosis is controversial among scientists. Some believe symbiosis should only refer to persistent mutualisms, while others believe it should apply to all types of persistent biological interactions (i.e. mutualistic, commensalistic, or parasitic). In this video we show how you can simply visualize all three.

UC Grad Slam is an annual contest in which master’s and Ph.D. students across UC campuses – in disciplines ranging from hard sciences to humanities – compete to sum up their research for a general audience. Grad Slam 2016 was held on April 22, at LinkedIn in San Francisco. More information at http://gradslam.universityofcalifornia.edu
Marine ecology in easter island
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.
