Science and Technology Log
The HI’IALAKAI continued running survey lines of the ocean floor near Nihoa. Scientists continued grouping together larger swaths of data in the drylab, like pieces of a puzzle emerging from the depths of the ocean. We cruised by Nihoa several times collecting benthic data.
I began the day answering emails from students and teachers. I edited a file of data in the drylab and flitted about taking pictures of people and places on board. The cruise is beginning to wind down, so there isn’t as much to do at this point and no boats are being deployed either. I must admit my stomach is a little upset from the rolling and pitching of the boat. I sleep terribly one night, then like a rock the next.
QUESTION OF THE DAY: CO Kuester (commanding officer) has given commands for the ship to arrive at the entrance to Honolulu Harbor by 0700 on Saturday, April 23rd. The ship has 260 nautical miles to still cover, and we travel ten knots an hour. 1) How many hours will it take us to reach our destination? __________________ 2) A nautical mile > a statute mile (mile on land) if…
1 nautical mile (1 knot) = 1.15 statute miles then… 260 knots =____________ statute miles?
(thanks to Lt. Wingate and ENS Jones for help with this question!)
ANSWER TO YESTERDAY’s Question: I have seen many sea creatures around the Northern Hawaiian Islands coral reef ecosystem. Animals such as the whitetip shark, sea turtles, and monk seals. These animals are all living things that eat other living things for energy. In a food web, they are called consumers.
