7-8 ANTARCTIC BIOMES Bio Accumulation Mercury and metal accumulation Human Impact ~Least-touched continent by humans Antarctic Penguins ~Many different types of penguins
~All share basic qualities/adaptations ~Some types of penguins are: Rockhopper Penguin

Adele Penguin

Emperor Penguin

Chinstrap Penguin

Erectrested Penguin

Fiordland Penguin
Gentoo Penguin

Galapagos Penguin

Humboltd Penguin

King Penguin

Little Blue Penguin

Magellanic Penguin

Macaroni Penguin

Royal Penguin

Snares Island Penguin

Yellow Eyed Penguin ~On the very South ~Not warm at all We're going to take you to a day in Antarctica!!!! YOU WILL LEARN ABOUT: ~Climate in Antarctica ~Plants and Wildlife ~Food chains + Food webs ~HOOOMAN impacts ~ Fun facts ~Type of biome/location ~History of Antarctica Location/Type of Biome ~ Located directly on south pole ~ Type of Biome Animals Although Antarctica is EXTREMELY cold it still has a variety of animals. How was it found? Three different types
Declared its own biome - An Ice biome - A desert biome - Its own biome Climate / Rainfall Coldest temperature ever recorded on Earth! Coldest temp
-128.6°F (-88.0°C) Less than 2 inches of snow fall each year. Antarctica has over 1000 species of animals life. Antarctica was once covered in lots of millimeters of snow Summer Average Temperature (Dec - Feb)
−10°C (coast) and −30°C (interior plateau)

Winter Average Temperature
−20°C (coast) and −60°C (interior plateau) (example of a food web) Released by anthropogenic and natural sources
Occurs in the atmosphere
A long lifetime (In the atmosphere) Mercury emitted by anthropogenic and natural sources occurs in the atmosphere mostly in the gaseous elemental form, which has a long lifetime in tropical and temperate regions. Once deposited in terrestrial and aquatic ecosystems the metal is partly re-emitted into the air, thus assuming the characteristics of global pollutants such as persistent volatile chemicals. In polar regions, during and after the sunrise, the photochemically driven oxidation of gaseous Hg by reactive halogens may result in areas of greatly enhanced Hg deposition. Mercury concentrations in soils, lichens, and mosses collected in a stretch between 74 degrees 30' S and 76 degrees 00' S, in ice-free coastal areas of Victoria Land facing the Terra Nova Bay coastal polynya, were higher than typical Antarctic baselines. The finding of enhanced Hg bioaccumulation in Antarctic terrestrial ecosystems facing a coastal polynya strongly supports recent speculations on the role of ice crystals ("frost flowers") growing in polynyas as a dominant source of sea salt aerosols and bromine compounds, which are involved in springtime mercury depletion events (MDEs). These results raise concern aboutthe possible environmental effects of changes in regional climate and sea ice coverage, and on the possible role of Antarctica as a sink in the mercury cycle.

YOUR FACE *runs away* Also I stole your timey-wimey detector THE END Allons-y! The name "Antarctica" comes from a Greek word that means "Opposite of north" Antarctica is the only continent not owned by any country Around 90% of Earth's ice is found on Antarctica About 70% of the Earth's freshwater is found in the Antarctica ice cap The thickest point in Antarctica's ice sheet is 4,776 meters deep and 2,160 meters thick The ice in Antarctica is melting 10x faster than it did 600 years ago Periodicals Bibliography http://www.inchinapinch.com/hab_pgs/polar/antarctica/animals.htm
