Howdy all,

This first week in Hawaii has already been an invaluable experience in helping me understand the role and responsibilities of a marine tech in contributing to a vital oceanographic time series. 

For the first two days of my internship, I was able to spend some time aboard the R/V Kilo Moana where I got to meet the crew and better understand the ship itself. While loading and preparing for HOT 345 with the science team, I learned how a CTD termination is performed, a basic job requirement for any marine technician. After helping the science team and crew pack for the cruise we were off to Station Kahe the next day to weight test the Hawboldt LARS wench system, perform a Hyperpro cast, CTD cast, and a trace metal cast. Even on the first day of the cruise, I was already being exposed to new scientific equipment and sampling techniques. After performing these preliminary tests and sampling we were off to Station Aloha, the primary sampling site for HOT cruises.

At Station Aloha I was introduced to even more new equipment and sampling techniques while learning about directing deck operations and getting to know my cruise mates better. The cruise was business as usual until there was a malfunction in the Hawboldt hydraulics system forcing the rosette and CTD to be moved to an alternative tension-based wench system that routed through the ship’s A-frame. Unfortunately, soon after this new wench system was set up it also malfunctioned when proof of tension was not maintained for the system, forcing the repair of the original Hawboldt system. This series of events required a new termination and hours of work, wasting valuable ship time. While this was not an ideal situation, it showed that anything can go wrong on a cruise and that complex problem-solving is a requirement for a marine tech. In this way, it was a valuable learning experience for me. 

The rest of the cruise remained relatively uneventful, and I was able to learn about computer networking systems and using Linux from one of the marine techs as well as discuss what a career as a marine tech might look like. We were able to complete our sampling at Station Aloha, the WHOTS mooring, and Station Kaena and return to Honolulu without any other issues. I am excited to continue updating this blog with the new skills and experiences I gain over the next week working with CTD systems and processing data.

Best,

Hunter
