Durvillaea antarctica

Durvillaea antarctica, commonly known as cochayuyo, is a large, robust bull kelp species and the dominant seaweed in southern New Zealand and Chile. D. antarctica has a circumpolar distribution between the latitudes of 29°S (in Chile) and 55°S (on Macquarie Island). It is found on exposed shores, especially in the northern parts of its range, and attaches itself with a strong holdfast. D. antarctica, an alga, does not have air bladders, but floats due to a unique honeycomb structure within the alga's blades, which also helps the kelp avoid being damaged by the strong waves.

Morphology

The blades of Durvillaea antarctica are green to golden brown with a leathery texture. The honeycomb structure of the blade gives strength and buoyancy. This novel structure is thought to be responsible for the wide distribution of this genus, as the kelp is able to float when its holdfast fails. It can colonise other coastlines in this manner, and has been shown to carry communities of invertebrates across vast ocean distances from one shore to another. It is thought that this 'rafting' with Durvillaea antarctica and other floating seaweeds allowed a wide range of species to recolonise sub-Antarctic shores scoured clean by ice during the last Ice Age.

Antarctica

Antarctica (US English ⁱ/æntˈɑːrktɪkə/, UK English /ænˈtɑːktɪkə/ or /ænˈtɑːtɪkə/ or /ænˈɑːtɪkə/) is Earth's southernmost continent, containing the geographic South Pole. It is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres (5,400,000 square miles), it is the fifth-largest continent in area after Asia, Africa, North America, and South America. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 kilometres (1.2 mi) in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.

Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Antarctica is considered a desert, with annual precipitation of only 200 mm (8 in) along the coast and far less inland. The temperature in Antarctica has reached −89.2 °C (−128.6 °F), though the average for the third quarter (the coldest part of the year) is −63 °C (−81 °F). There are no permanent human residents, but anywhere from 1,000 to 5,000 people reside throughout the year at the research stations scattered across the continent. Organisms native to Antarctica include many types of algae, bacteria, fungi, plants, protista, and certain animals, such as mites, nematodes, penguins, seals and tardigrades. Vegetation, where it occurs, is tundra.

Eight Below

Eight Below is a 2006 American adventure drama film based on Antarctica by Toshirô Ishidô, Koreyoshi Kurahara, Tatsuo Nogami and Susumu Saji. It was produced by Patrick Crowley and David Hoberman, directed by Frank Marshall with music by Mark Isham and written by David DiGilio. It stars Paul Walker, Bruce Greenwood, Moon Bloodgood, and Jason Biggs. It was released theatrically on February 17, 2006, by Walt Disney Pictures in the United States. The film is set in Antarctica, but was filmed in Svalbard, Norway, Greenland, and British Columbia, Canada. The film received positive reviews from critics and it earned $120.4 million on a $40 million budget.

Plot

In 1993, Jerry Shepard (Paul Walker) is a guide at an Antarctica research base under contract with the National Science Foundation. UCLA professor, Dr. Davis McClaren (Bruce Greenwood), arrives at the base. He presses Shepard to take him to Mount Melbourne to attempt to find a rare meteorite from the planet Mercury. Shepard does so, ignoring his own intuition, which tells him it is too late in the season to complete such a treacherous route, and decides that the only way to get to Mount Melbourne is by dog sled.
