After a long red-eye flight from American Samoa, NOAA Officer Rebecca Waddington greeted me at the Honolulu International Airport.  As the sun came up, we drove to pier 45. As I made my way onto the ship, I was introduced to the crew: The NOAA officers, the deck crew, the engineer crew, the scientists, and the doctor. The next few days were filled with walking around Honolulu and getting used to ship life.

The sun was just above the horizon and already the KA’IMIMOANA was buzzing with movement as the crew was getting ready for an on-time departure. The horn sounded as we sailed out of the harbor. The plan of the day was to conduct a helicopter emergency drill and then return to the fueling dock for a six-hour fueling session. Half way through with fueling, we were informed that our departure was going to be delayed till Friday morning due to some electrical difficultly with the alarm systems.

All systems were go as we headed out of the fueling harbor at noon. The ocean was calm but there was an uneasiness in some of the crew as it is believed to bad luck to sail on a Friday.

All new hands onboard attended a safety lecture where we learned what to do in case of: man-overboard, fire and collision, or abandoned ship emergency.  A while later an abandoned ship drill was conducted. All hands had to grab their assigned gear and meet at their designated safety boat. Our “gumby suits” had to be put on and whistles checked, after which we were able to dress down without PFDs (Personal Floatation Device) on to await further instructions. As the sunset an amazing full moon rose to fill the night sky. What a wonderful night!

The morning started with my assisting one of the researchers with fixing a CTD.  The Conductivity, Temperature & Depth instrument measures the conductivity and temperature of water, which will assist in obtaining the amount of salinity.  Using the salinity and the temperature, the density of the water can be determined.  In turn, knowing the densities of the ocean, scientists can determine currents.  The main CTD instrument is surrounded by 14 or so Niskin Bottles.  These bottles collect water at a certain depth to be used in a variety of other tests on ship or on land. All new hands onboard watched a “HAZMAT: Your Right to Know” video and then the ship’s familiarization video. That afternoon we had a fire drill. All scientists meet in the galley unless the fire is in the galley, and then we meet on the boat deck and act as runners for the ship’s crew; if any vents need to be closed or boundaries need to be checked, it’s all part of a team.
