NOAA Teacher at Sea
Onboard NOAA Ship KA‘IMIMOANA
January 4 – 22, 2010
Geographical Area: Hawaiian Islands
Date: January 6, 2010
The KA is under her own steam, well actually diesel and electric, and we are making 10 knots (you should figure out how fast that is in miles per hour) at a heading of 173 degrees. The KA uses diesel generators to create the current to drive here electric propulsion motors. She is a vey quit ship because of this configuration which was part of her original deign…to be quite. The KA is a former Navy antisubmarine warfare ship and needed to be quiet to play her role listening for submarines that might have been lurking around the oceans. Now that quiet nature makes it nice for those of us about to have our first night at sea.
Our current position was 157degrees 51 minutes and 7 seconds west longitude (157:51:07 W) and 22 degrees 55 minutes and 8 seconds north latitude (22:55:09N) at 19:30 lcl on the 5th of January. At that time we had been at sea for about five hours and have many more to go on our way to work the 155 W Buoy line. Sunset was fantastic, but very short. It seems to take almost no time to go from day to night here in the tropics. You can see how it looks behind some of the “birds” (anemometers) that will measure windspeed and direction on the buoys. We are now (09:10 lcl) about 40 nautical miles south of the Big Island and can just see it in the distance. It will be some time before we see land again.
Since we are running a little slow on the internet I will simply post a few images from our first day rather than a video. I will attempt to post a video or two later on but currently we are limited on our bandwidth to about 128K.
For two days I have been overwhelmed as I observed all of the aspects of the crew’s preparation for the TAO mission to Samoa. I am fascinated with everything about this operation – watching the crew load the ship, observing the ship being fueled, viewing the massive nuclear submarines located in Pearl Harbor, and assembling the sensors that collect climate data from each of the buoys we will deploy. Yesterday, in preparation for our voyage, we continued to calibrate instruments and assemble sensors.Last night was our first night at sea, I slept like a baby -the gentle rocking of the boat was like being in a giant cradle.
