The Arctic Ocean
The Arctic Ocean (also called Northern Icy Ocean or Northern Ocean), located in theNorthern Hemisphere and mostly in the Arctic north polar region, is the smallest and shallowest of the world's five major oceanic divisions. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea or simply the Arctic Sea, classifying it a mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be seen as the northernmost part of the all-encompassing World Ocean.
Almost completely surrounded by Eurasia and North America, the Arctic Ocean is partly covered by sea icethroughout the year (and almost completely in winter). The Arctic Ocean's temperature and salinity varyseasonally as the ice cover melts and freezes; its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy freshwater inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities. The summer shrinking of the ice has been quoted at 50%. The US National Snow and Ice Data Center (NSIDC) uses satellite data to provide a daily record of Arctic sea ice cover and the rate of melting compared to an average period and specific past years.
扩展阅读：雅思听力高分必备三大技巧
一、先看问题，寻找关键词
在雅思听力训练中，考生一定要养成先看问题，寻找问题的关键词，在去听原文。这样能锻炼考生对答案的敏感度。在看问题的时候，考生可以知道这题的出题方向是什么，是偏重原因的，还是偏重数字的，还是人物关系。考生可以用笔画下关键词，提高反应能力，还能有效进行同义转化。
二、注意判断题，多记连接词
判断题是考验考生是否能听懂原文中所提到的内容以及各种抉择。通常的解题技巧是用排除法来得到正确答案，这时候难度会加大，要求考生能听懂每段话的详细意思。因为里面通常还会出现转折，也就是前段说了一个观点，最后反驳这个观点，考生很容易产生误导，选择第一个听到的观点。
三、把握原文信号词，注意填写格式
在雅思听力考试中，最考验的就是考生对细节把握的能力。很多像电话号码，住址，门牌号，还有邮编号都需要考生在听的时候就要记下来。还要记一下专有名词，例如名字，数字，食物，还有地方。
