Have you ever been too afraid to enter the vast ocean because of what’s lurking out there? Well, OCEARCH, a non-profit organization, are undergoing an operation to research and better understand sharks. Shark tagging has been in operation to figure out what sharks get up to, where they go, and what their habits are.

OCEARCH are tagging white pointers (great whites) and tiger sharks off the West Australian and Queensland coasts. So far they have tagged 47 sharks with only one shark casualty. OCEARCH are planning to better understand their migratory habits, diets, reproduction routine and their behavior by fitting them with trackers.

On a platform which hangs off the side of the boat, the sharks are raised for under 15 minutes whilst they undergo twelve procedures including satellite tracking, blood samples, acoustic and accelerometer tags, all of which are mounted on the dorsal fin. The sharks then are lowered into the water where they safely swim away unharmed. The trackers will fall off the sharks dorsal fins in about 12-18 months, allowing us their location and habits to be recorded for the time being. …show more content…
OCEARCH have now got an app where the satellite trackers will show us real-time screening of the sharks movements. This will greatly benefit us with safety and the feeling we are being looked after. The tagged sharks are living as normal and are being useful to OCEARCH’s research which will help us better understand their movements and habits. “We are only beginning to understand how these sharks move between the warm temperate waters of New South Wales in the summer, to the sub-tropical and tropical waters of Queensland in winter,” said University of Queensland, shark scientist, Bonnie

Tattoo

...some people view it as the "devil's art", the changing culture and acceptance of tattoos is becoming more mainstream and viewed as an expression of individuality. Some people claim that tattoos have been around since 12000 B.C. Generally the earliest known tattoos are from the Iceman, a mummy found on what is now the Italian-Austrian border. The Iceman has been carbon dated as over 5000 years old. Prior to this discovery, Egyptian mummies were thought to show the earliest signs of tattoos. These tattoos usually were found on female mummies. The markings on the female represented their status and relation to the ruler or pharaohs of the time. As the Egyptian empire spread so did the influence of tattooing on other cultures and societies. Egyptians spread the art of tattoos throughout the world and different cultures adapted tattooing. Greeks used tattooing to mark rankings of spies, slaves and criminals. These markings were usually done on the face. Facial tattoos were also used in Japan on criminals. They were tattooed on the forehead with a design to signify a dog after three offences. In Japan, tattoos were also used for religious as well as social meanings. The Ainu, who introduced the art of tattooing to the Japanese, still use tattoos to mark girls coming of age and the status of married women(Tattoos by Design.com). According to DesignBoom, "Polynesian tattooing [is] considered the most intricate and skillful of the ancient world". The elaborate tattoos of the...

A Local Ecosystem

...Biology – Module 1 – A Local Ecosystem The distribution, diversity and numbers of plants and animals found in ecosystems are determined by biotic and abiotic factors. Compare the abiotic characteristics of aquatic and terrestrial environments. An aquatic environment is one that consists in water. The abiotic characteristics of an aquatic environment include: Buoyancy – This refers to the upward pressure (or thrust) that is applied on the organism by its medium. Buoyancy is determined by the density of the medium and determines the floating ability of an organism. Water provides sufficient buoyancy for many organisms, e.g., the jellyfish. If a jellyfish is taken out of water and placed on land it will disintegrate by spreading apart. Thus, the water provides enough buoyancy (pressure) in order to keep the shape of the jellyfish. Pressure – This is the downward force that is applied on an organism by its medium. In water, the pressure is dependent on the depth. Organisms that live at the bottom of the ocean experience the effects of extreme pressure and they must have specific adaptations that enable them to survive in such harsh environments. Temperature Variations – Usually in an aquatic environment there are minimal temperature variations to that compared with terrestrial environments. The temperature variations also depend on the size of the body of water; a large body of water will experience much less temperature variations than a smaller body...

Electricity

..."amber-like"coined in the year 1600 from the Greek ήλεκτρον (electron) meaning amber(hardened plant resin), because static electricity effects were produced classically by rubbing amber. Usage In general usage, the word "electricity" adequately refers to a number of physical effects. In scientific usage, however, the term is vague, and these related, but distinct, concepts are better identified by more precise terms: * Electric charge: a property of some subatomic particles, which determines their electromagnetic interactions. Electrically charged matter is influenced by, and produces, electromagnetic fields. * Electric current: a movement or flow of electrically charged particles, typically measured in amperes. * Electric field: an influence produced by an electric charge on other charges in its vicinity. * Electric potential: the capacity of an electric field to do work on an electric charge, typically measured in volts. * Electromagnetism: a fundamental interaction between the magnetic field and the presence and motion of an electric charge. The most common use of the word "electricity" is less precise. It refers to: * Electric power provided commercially by the electrical power industry. In a loose but common use of the term, "electricity" may be used to mean "wired for...

Life of Pi

...Acclaim for Yann Martel's Life of Pi "Life of Pi is not just a readable and engaging novel, it's a finely twisted length of yarn— yarn implying a far-fetched story you can't quite swallow whole, but can't dismiss outright. Life of Pi is in this tradition—a story of uncertain veracity, made credible by the art of the yarn-spinner. Like its noteworthy ancestors, among which I take to be Robinson Crusoe, Gulliver's Travels, the Ancient Mariner, Moby Dick and Pincher Martin, it's a tale of disaster at sea coupled with miraculous survival—a boys' adventure for grownups." —Margaret Atwood, The Sunday Times (London) "A fabulous romp through an imagination by turns ecstatic, cunning, despairing and resilient, this novel is an impressive achievement. . . . Martel displays the clever voice and tremendous storytelling skills of an emerging master." —Publisher's Weekly (starred review) "[Life of Pi] has a buoyant, exotic, insistence reminiscent of Edgar Allen Poe's most Gothic fiction. . . . Oddities abound and the storytelling is first-rate. Yann Martel has written a novel full of grisly reality, outlandish plot, inventive setting and thought-provoking questions about the value and purpose of fiction." —The Edmonton journal "Martel's ceaselessly clever writing . . . [and] artful, occasionally hilarious, internal dialogue . . . make a fine argument for the divinity of good art." —The Gazette "Astounding and beautiful. . . . The book is a pleasure not only for the subtleties of its philosophy...

Hia Its Ya Birthdya

...Yann Martel: Life of Pi life of pi A NOVEL author's note This book was born as I was hungry. Let me explain. In the spring of 1996, my second book, a novel, came out in Canada. It didn't fare well. Reviewers were puzzled, or damned it with faint praise. Then readers ignored it. Despite my best efforts at playing the clown or the trapeze artist, the media circus made no difference. The book did not move. Books lined the shelves of bookstores like kids standing in a row to play baseball or soccer, and mine was the gangly, unathletic kid that no one wanted on their team. It vanished quickly and quietly. The fiasco did not affect me too much. I had already moved on to another story, a novel set in Portugal in 1939. Only I was feeling restless. And I had a little money. So I flew to Bombay. This is not so illogical if you realize three things: that a stint in India will beat the restlessness out of any living creature; that a little money can go a long way there; and that a novel set in Portugal in 1939 may have very little to do with Portugal in 1939. I had been to India before, in the north, for five months. On that first trip I had come to the subcontinent completely unprepared. Actually, I had a preparation of one word. When I told a friend who knew the country well of my travel plans, he said casually, "They speak a funny English in India. They like words like bamboozle." I remembered his words as my plane started its descent towards Delhi, so the word bamboozle ...

Effective Learning Techniques

...Improving Students’ Learning With Effective Learning Techniques: Promising Directions From Cognitive and Educational Psychology Many students are being left behind by an educational system that some people believe is in crisis. Improving educational outcomes will require efforts on many fronts, but a central premise of this monograph is that one part of a solution involves helping students to better regulate their learning through the use of effective learning techniques. Fortunately, cognitive and educational psychologists have been developing and evaluating easy-to-use learning techniques that could help students achieve their learning goals. In this monograph, we discuss 10 learning techniques in detail and offer recommendations about their relative utility. We selected techniques that were expected to be relatively easy to use and hence could be adopted by many students. Also, some techniques (e.g., highlighting and rereading) were selected because students report relying heavily on them, which makes it especially important to examine how well they work. The techniques include elaborative interrogation, self-explanation, summarization, highlighting (or underlining), the keyword mnemonic, imagery use for text learning, rereading, practice testing, distributed practice, and interleaved practice.   To offer recommendations about the relative utility of these techniques, we evaluated whether their benefits generalize across four categories of variables: learning...
