I’ll be spending about 3 weeks working in the area where a large chunk of the Larsen C ice-shelf broke off. Enter your email address to follow this blog and receive notifications of new posts by email. The coastal areas were packed full of elephant seals, fur seals, penguins, petrels and albatross. I got the job at British Antarctic Survey second time round. They helped me add meaning to my work and place the results in the context of the system. The next few weeks were a whirlwind of activity: medicals; advanced boat driving training; first aid courses; and learning to drive a JCB. This area, west of the Mariana Trench, is where plate spreading and submarine volcanism are concentrated. I was thirteen at the time. Life in the Freezer was the series that inspired me to work in the Antarctic, which set me on the road (or boat) to South Georgia for 2 years and then to studying for my PhD at Newcastle University. But life on South Georgia had to come to an end. Required fields are marked *. I applied. There is no way I could have undertaken this work without the support of so many scientific and technical disciplines. My decision paid off because the job was advertised again. The floor of the deep ocean is almost devoid of life, because little food can be found there. It consists of two parts and includes many aquatic animals, foliage, scenery and more. Match. Blue planet the deep. I applied. Flashcards. These beasties sometimes even feed on the hydrogen sulphide that leaks out of the vents too! He has also discovered hydrothermal vents and “black smokers” in the Galapagos Rift and East Pacific Rise in 1977 and 1979. Discover the spectacular smoking chimneys of the hydrothermal vents. I spent hours watching video footage of the deep-sea Patagonian toothfish and crabs attracted to baited deep-sea landers as part of my final year project. I spent two years on the island doing science that helped manage the commercial fisheries around the island. Whether you are into maths, biology, chemistry, physics, engineering, geology or microbiology, there is a career for you that involves our Blue Planet. The Blue Planet - Seas of Life, is an excellent documentary. Featured image credit: http://www.mashable.com, Your email address will not be published. Some of the worksheets displayed are ocean world the deep blue planet 5 6 ovr l lesson 1 where in the world is the open ocean g3 u2 l3 lesson 3 dare to compare gems macmillan mcgraw hill 5 hydrothermal vents work ocean currents name period. Created by. Bill Nye discusses the discovery of hydrothermal vents on the ocean's floor. The show will also appear in Canada on BBC Earth early next year. My work focused on what the animals were eating and constructing food webs at each of the sites we visited. When the mineral-laden water, whose temperature may exceed 400 degrees Centigrade, vents into the cold ocean, some of the dissolved minerals immediately separate out to form particles of metal sulfides, which accumulate around the vents. Hot, mineral-rich fluids supply nutrient chemicals. One of these hydrogen sulfide-making species is Pyrolobus fumarii (or "fire lobe of the chimney"), that was first isolated from a hydrothermal vent at the Mid-Atlantic Ridge. Next year, I am going to explore the seabed that has not been exposed to open waters for approximately 120,000 years. I worked with scientists that had backgrounds in chemistry, geology, microbiology, biology, computer science and supported by mechanical and electrical engineers, technicians and a large ships crew. The episode showed the widespread death and, The BBC managed to capture extremely rare footage of an eruption of an, I found it incredible how certain underwater creatures have adapted. The cold seawater is heated by hot magma and reemerges to form the vents. Most likely, Joye said, new vents have opened since then, or the rate of hydrothermal fluid flow has increased. So, I just asked the question “What skills and experience do I need to get the job?”. What astounding discovery was made by a deep sea submersible in the Gulf of Mexico in 1990? I got the PhD position. Required fields are marked *. Hydrothermal vents are known to occur along tectonic boundaries in the Earth’s crust, so the >56,000 km-long mid-ocean ridge system is a great place to begin our search. There was a huge amount of relief on the boat as the scientists got to work. The research team has been assembled from a number of different universities and institutions and will once more be a collaborative effort. She was the doctor in my second year. They were very similar. Seeps and vents are essentially underwater vacuums and geysers where breaks occur in the Earth's tectonic plates. I was even there at the moment when the crab stuck its claw into the hot water. I realised during that series that I wanted to be a scientist but not just any scientist, one that went to the Antarctic. Write. The island of South Georgia was truly stunning. The PhD was part of 5 year NERC programme trying to find and understand hydrothermal vents in the Antarctic. I spent about four months at sea in the Antarctic across three research expeditions, during my PhD at Newcastle University. It will also go down as a big landmark in my research career. Sorry, your blog cannot share posts by email. Hydrothermal vents are simply underwater geysers, comprised of cracks or fissures in the ocean floor from which mineral-rich and geothermally heated water bursts forth. I worked on fish larvae, managed an aquarium which housed crabs, aged Patagonian toothfish using their ear bones called otoliths, undertook diet studies on icefish and went on fish stock assessments around the island. It just goes to show that sometime adventures never truly end. Start studying Blue Planet- Deep Ocean. We discovered whole new communities and species and mapped where the different animals lived around the vents. The crabs live in areas where hot water pores over them which provides the conditions for the bacteria to grow. This included: going back to university and doing a masters in Oceanography; learning to drive boats; sea survival training; and going to sea as a fisheries observer on a Portuguese deep-water trawler off Canada. And yet, Blue Planet succeeded amply. I took Maths, English, History, Biology and Chemistry Highers and got onto a marine biology degree course. At the surface of the ocean, water becomes steam at 100 degrees centigrade. Posted on November 8, ... Hydrothermal sea vents that belch out heat that could melt metal lead can be withstood by specially adapted creatures (the episode showed crabs and shrimp). I was finally going to South Georgia! Although it is narrated by David Attenborough, it is not a part of his "Life of" series. The show will also appear in Canada on BBC Earth early next year. For many people, Blue Planet II will inspire them too, some of whom will go into marine science as well. The team had discovered a hydrothermal vent site that hadn't existed in 2008. It is a beautiful work of art, visually stunning, and also of course very entertaining which ultimately is what is was made for. The footage features the Endeavour hydrothermal vents, a wonder of nature that's located 250 km southwest of Vancouver Island … Spell. Little did I know that in just over ten years I would be living and working on the island. I moved to Newcastle. PLAY. The inspiration that lead me to sitting on a ship, watching a video feed from a remotely operated vehicle over two kilometers below, began with another David Attenborough documentary. This indicated that the bacteria living on those crabs were its food source. After a number of hours searching the seafloor we eventually found our first hydrothermal vent field. Then I was finally deployed. Texas A&M Oceanographers On Pacific Expedition Will Be Featured On BBC Blue Planet Live March 27-28 Dr. Jason B.
