What happens is that you set the tag to detach from the shark after a fixed period, in this case it was eight months, and literally to the day the tag popped off, drifted up, said hello to the satellite and sent, not all the data, but enough data for us to use.
经过一段固定时间后，你往往还要把标签从姥鲨身上分离下来 这一般是在8个月后 到那天标签被取下，漂浮起来，然后向卫星发送数据 并不是发送所有数据，但对我们来说已经足够了
