Drake Passage-aboard the tour ship Explorer February 19 We were welcomed today by the captain and crew.They gave us warm Antarctic jackets and talked happily with us.Sea birds followed the ship closely,sailing in the cold wind.As we headed south,we saw a pink ship in the distance.Our captain explained that it was not a ship but an iceberg-the first one of our trip. |
Deception Island,Antarctica February 21 We landed on Bailey Head,where thousands and thousands of penguins (企鵝) greeted us.The crew gave us a set of rules to follow to protect the environment.Mark,one of the scientists on our ship,asked us to bring him any rubbish that we find.He is studying the amount of rubbish created by tourists in Antarctica each year. At night we listened to Christina,a woman scientist.She explained the plant and animal life to us.Then she showed us a DVD on Antarctica. The more I see,the more I want to learn. |
Cuverville Island,Antarctica February 23 We awakened this morning to the noisy sound of penguins.They're loud!We met a team of biologists living in tents.They are studying the effect of tourists on baby penguins.When our captain invited the biologists to come on board for a hot shower,they joined us immediately.Then we cruised (乘郵輪) through the icebergs,which appeared in unbelievable shapes and sizes,as the sun was sinking in the sky.They seemed to be works of art. |
