During winter, the Southern Ocean sea ice freezes, essentially doubling the size of Antarctica. The extent of the sea ice is about 17 to 20 million square kilometers.
What else can I help you with?
When does antarctica have the minimum extent of sea ice?
March.
Is there a sea in Antarctica?
There is a sea but it is solid ice
Is the sea ice around Antarctica greater in September or February?
Probably September, since its greatest extent is in June and it hasn't melted. In February, the sea ice has melted by exposure to sun 24/7, and has not yet frozen over.
How far does the sea ice extend around Antarctica?
Your answer depends on the time of year when you want to measure the ice. In winter, the sea ice freezes and almost doubles the size of the Antarctic continent. The edges of the ice are ragged and change, depending on the action of the liquid sea.
How are the seas of the Antarctic different in the winter than in the summer?
During winter, the sea ice of the Southern Ocean freezes to the extent that it appears to double the size of Antarctica.
How does Antarctica's melting ice affect global sea levels?
Antarctica's melting ice will flow into the sea. This will raise sea levels around the world. There is enough ice on Antarctica to raise sea levels by 60 metres (200 feet).
How much does the Antarctica grow a year?
Essentially, continents do not 'grow', but sea levels can drop, thus expanding the visible land. However, in the case of Antarctica, 98% of it is covered with an ice sheet. During the winter, the Southern Ocean freezes, and the sea ice attaches itself to the continental ice sheet. This, apparently, can 'double' the size of the continent, when, in fact, it is simply a way to describe the extent of the ice.
What 2 water forms in Antarctica?
Any water in Antarctica forms into ice, either sea ice or fresh-water ice.
Why is the base of Antarctica's sea ice often brown in color?
Antarctica's sea ice gets its colour from the algae that bloom under it after the sun comes up; frozen to the under side of the sea ice, it appears brown.
What is drifting ice in antarctica?
Icebergs (drifting ice) in Antarctica have broken off from the glaciers and ice shelves that stretch out over the sea at the continent's coastline.
Is Antarctica causing sea level rise?
No. Antarctica is a continent. It is mostly covered by ice. It does nothing by sit there surrounding the south pole. The ice that is melting on Antarctica is contributing to the rise of sea levels, but the continent is not doing this.
When does sea ice form in high latitudes the sea ice has?
Sea ice typically forms in high latitudes during the autumn months as temperatures drop and ocean waters begin to freeze. This process generally starts in late September to early October in the Arctic and can continue into the winter months, reaching its maximum extent typically around March. Factors such as air temperature, ocean currents, and wind patterns influence the timing and extent of sea ice formation.
