In New Zealand, southern right whales were hunted to near extinction1 about a century ago. Since that time, the population has slowly recovered.
在新西兰，南露脊鲸在大约一个世纪前被捕杀至濒临灭绝。但自那时起，其数量就缓慢回升。

My name is Dr Emma Carroll. I'm the lead scientist on a research project called 'Tohora no Aotearoa', which is a Maori phrase that means 'southern right whales of New Zealand'. We estimated there are around 2000 whales in 2009.

“我是艾玛·卡罗尔博士。我是一个名为 ‘Tohora no Aotearoa’ 的研究项目的首席科学家，这是一个毛利语短语，意思是 ‘新西兰南露脊鲸’。我们在2009年估计约有2000头鲸鱼。
However, nobody's really gone back to look at them over the last decade.
然而，在过去十年间，没有人真正回去查看它们。
And so, this year and last year, we conducted surveys at their main wintering ground down in the Auckland Islands, which is about 450 kilometres south of the main islands of New Zealand.
所以，今年和去年，我们在这些鲸鱼的主要越冬地开展了调查，即新西兰主岛以南450公里的奥克兰群岛。”

So, what we did is we used satellite tags
