Discrete water sampling is resource and time intensive; however, it remains a key method in marine chemistry and trace metals research. Existing autonomous water samplers (or autosamplers) are often costly (i.e., ~$35K to ~$40K), bulky and extremely complex, making them inaccessible to scientists without engineering backgrounds.
As part of their Coastal Health Collective funded by Mānoa Strategic Investment Initiative, A. Kealoha (OCN), N. Hawco (OCN), E. Nalley (Sea Grant), C. Pagniello (ORE) and C. Nelson (OCN) proposed to develop a low-cost, open-source kit for undergraduate students from non-engineering majors to build Eulerian autosamplers (Goal 3, Obj 3). These autosamplers will also be used to ground truth measurements made by a novel drifting package, which includes an autosampler, across Lahaina coral reefs (Goal 2, Obj 2b).
In this course, you will design this autosampler kit.
