这通常是在第一天潜水后或是一系列潜水的第一潜后立即出现的。

This was always immediately after the first dive day or first dives in a series.

我非常同意楼主的意见，第一潜，应该找个容易的潜点，尤其是在Galapagos那种复杂环境的地方。

Yes, absolutely. The first dive with divers whom one does not know, especially in a challenging dive environment, should be an easy dive.

我很纳闷，作为第一个正式下潜前的简报，怎么会如此草率。

I was surprised at the brevity of the briefing, especially as it was our first actual dive of the trip.
