Deep-ocean trench research provided University of Hawaiʻi<\/span> at Mānoa students in the Global Environmental Science<\/a> (GES<\/abbr>) bachelor\u2019s degree program valuable experience and inspiration in fall 2023. The mission of the oceanographic cruise aboard the research vessel Kilo Moana<\/em> was to test and refine the performance of the Hadal Water Column Profiler<\/a>, a unique scientific instrument designed to study the physical, chemical and biological properties of the water in the deep-ocean trenches.<\/p>\n

“These deep ocean research cruises provide great opportunities for our students to engage in hands-on science, experience life at sea, and envision possible career paths—not just research scientists, but also the engineers and ship\u2019s crew that all work together to conduct successful at-sea observations,” said Glenn Carter, chief scientist of the Kilo Moana<\/em> cruise and associate professor of oceanography at the 糖心视频<\/abbr> Mānoa School of Ocean and Earth Science and Technology<\/a> (SOEST<\/abbr>).<\/p>\n

Eight undergraduate and four graduate students joined Carter and faculty members from the Department of Oceanography<\/a>, including deep-sea biologist Jeff Drazen, chemical oceanographer Chris Measures, and biological oceanographer Craig Nelson for the four-day expedition off Oʻahu\u2019s<\/span> Waiʻanae<\/span> Coast.<\/p>\n

“The experience turned out to be far more than what I expected, in the best way possible,” said Mattia Da Fieno, GES<\/abbr> student and cruise participant. “It was an incredible opportunity that both opened my eyes to how a lot of the scientific world works and let me put a lot of the skills I have been learning to good use.”<\/p>\n

In addition to the hadal profiler testing, the team collected zooplankton (tiny, floating animals, such as krill) using net tows, and measured vertical profiles on water properties using a Conductivity-Temperature-Depth (CTD<\/abbr>) sensor package.<\/p>\n

The cruise was structured so that all the undergraduate students were able to assist or observe in all the various operations, including sorting zooplankton and analyzing the CTD<\/abbr> water samples. The zooplankton and CTD<\/abbr> data will be used to understand the effect of islands on the marine food web.<\/p>\n

“Going out to sea to do research has been one of my biggest dreams since I started college,” said Ande Westerhausen, GES<\/abbr> student and cruise participant. “My most memorable experiences on the ship were the late nights processing zooplankton and bonding with my lab mates. Aboard the ship I quickly fell in love with the constantly busy environment where something is always going on.”<\/p>\n
