The story I wanted to do initially was just a small focus to look at the few weeks each year where these animals migrate down from the Canadian arctic to the Gulf of St. Lawrence in Canada And all of this is played out against the backdrop of transient pack ice that moves with wind and tide.
现在，我想说的报道，起初 只是小小的关注一下，在每年的几个星期中 这些动物为了求爱，交配和产子 从加拿大境内的北极圈迁徙 到加拿大的圣劳伦斯海湾。 而这一切都是为了把握住 被风和洋流移动的 转瞬即逝的浮冰。
