Seeing how the Hawaiian islands affect the distribution of critters will be interesting as well. I think there may be a whole bunch of 'empty' blue water between Monterey and Hawaii. However, many gelatinous critters like salps and doliolids can make a living in even nutrient poor waters and I expect to see them on our dives. The best part of a cruise is the feeling that comes from being more a part of the ocean than apart from it. I wanted to do something that was stimulating, challenging and fun.
Marine biology holds promise of all that as well as the thrill of discovery.
Although research cruises are usually hard work and long hours, at no other time are these things more apparent. Find scientists that do interesting things, get to know and help them. It's important to find more than one.
