Working primarily with the Fish REA team, I'm used to having up to four people at most in the water at a given time during a survey. The reason is fairly simple, fish don’t like being disturbed. Today was a markedly different experience as I jumped aboard the biggest field boat on board the Hi’ialakai, HI-1, and went on a documentary dive with the benthic, oceanography, and ARMS teams.
It isn’t just the sheer number of people on an HI-1 dive that differs from a regular day out with the Fish REA team; it is also what they are doing. To successfully establish fish counts, divers hover quietly several feet above the bottom watching and noting the behavior of their subjects. In contrast, today the ARMS team was both deploying new settling plates and collecting baseline units which were stationed at this site two years ago, just after the Marine National Monument designation took place (http://www.fws.gov/marianastrenchmarinemonument/).
The Fish REA team does its best to blend in with the surroundings bringing minimal gear; today a single oceanography diver brought more equipment to the bottom than could possibly be carried once filled, more than doubling his size and weight.

Yes it is true, Fish REA folks can sometimes be seen looking down into a hole trying to identify a camouflaged fish or eel, but when one dive buddy is looking down the other is most likely looking up and around. In contrast, I couldn’t get a single member of the benthic, oceanography or ARMS teams to look up for this photograph.
In the end I learned that you don’t absolutely need to have a lot of big fish around to have an enjoyable and educational dive, especially when algae experts are willing to show you what it would look like if a barracuda in the vicinity decided to charge the oceanography samples.

Thanks to everyone for another great day on Leg 2 of MARAMP.
Google earth seems to indicte HI is anchored off of a golf course in Saipan. wish I was there, NICE! enjoy
