Seminar: Innovative, Interdisciplinary Tools to Study Marine Animals in Our Changing Ocean
POST 723 1680 East-West Road, Honolulu, HI, United StatesCamille Pagniello, Ph.D. Assistant Researcher & SOEST Early Career Fellow Hawai’i Institute of Marine Biology University of Hawai‘i at Mānoa Although an abundance of ocean data has been gathered since the year 2000, the ocean remains under-sampled. In many instances, there is still a scarcity of data at any one location and time. However, the rise of small, and efficient microcontrollers and single-board computers has catalyzed the development of low-cost, open-source, “do-it-yourself” ocean observing technologies. Combined with advances in data science, signal processing and machine learning, there is a real opportunity to move beyond traditional and expensive oceanographic instruments and
