Report at Institute of Biological Sciences Ålesund, Norwegian University of Science and Technology (NTNU). (FREDELUCES ELLARIZZA TISADO, Course of Applied Marine Environmental Studies)
From October 21, 2024 to January 4, 2025, I did an internship in Institute of Biological Sciences Ålesund, Norwegian University of Science and Technology (NTNU). I did a collaborative research with Dr. Lars Christian Gansel and Dr. Snorre Bakke on their acoustic telemetry project for position tracking of crabs. Conventionally, acoustic receivers listening to the tagged crabs are stationary. This setup limits the coverage area of telemetry network, and becomes costly to maintain when more stationary receivers are added. To address this, we developed a drifting acoustic receiver with GNSS/GPS receiver which we will simply call as drifters. The GNSS/GPS receiver gives position of the acoustic receiver, so that every time a sound signal is received, the location of the acoustic receiver is known.
My main task in this project focuses on the prototype development, deployment, and data analysis. By using information from range tests between an acoustic receiver and transmitter, we can identify the probable area of location of crabs when a sound signal is received. To localize a crab, we deployed three drifters. We plan to continue this research after I came back to Japan. We are hoping that this project could be published to help researchers and industries interested for marine animal tracking. Aside from this, I also joined fieldwork for getting plankton samples for their salmon lice research.
Colleagues in NTNU IBA are approachable and friendly, and it felt easy to do research work with them even if I am from a different field. In this internship, I realized and acknowledged the importance of doing interdisciplinary research. This gave me an opportunity to think how my research background can contribute in solving bigger research problems. I was also able to meet some international students in NTNU, and join a cabin trip where we saw the beautiful Northern Lights. During free time, I visited some museums and walked around the city center. I also met two GNSS researchers from SINTEF, Trondheim, Norway that are working with solutions for GNSS spoofing and jamming.
I'd like to thank the Marine AI Office, Kino-sensei, and Takenawa-sensei for organizing this internship program for students in the Marine AI program. I am also thankful to NTNU IBA for their warm welcome and sharing their knowledge and friendship with me. To all students that might be reading this, I strongly encourage you to join such programs. I can attest that it will help deepen your research skills and establish collaborative work with other researchers.
