And these are some new breed of sounding line?

那些新式的测验器又是做什么用的呢？

They're thermometric sounding lines that report water temperatures in the different strata.

那些是温度测验器，给我报告海底下面各水层的温度。

These were the same waterways where Captain Denham, aboard the Herald, payed out 14,000 meters of sounding line without finding bottom.

就是在这一带海水中，海拉尔号的邓亨船长曾投下一万四千米长的探测器，但没有达到海底。也是在这里。
