Ask HN: What does the Google Ocean team do?

I was out for dinner with family last night, when I noticed a group come into the restaurant wearing Google Ocean fleeces. One member of the group was carrying a laptop and some documents, from which I surmised that I was witnessing a project team dinner. Does anyone know what the Google Ocean team might be doing in the field? Could they be piloting the Google Ocean View submersible? I'm in North Vancouver, British Columbia.
