Mathematical modeling and numerical simulation of wave attenuation in sea ice
Watanabe 112 2505 Correa Rd, Honolulu, HI, United StatesDr. Philippe Guyenne Professor Department of Mathematical Sciences University of Delaware Location Information **This seminar will be held both in person (Watanabe Hall 112) and over Zoom** Meeting ID: 961 6222 2366 Passcode: OREseminar https://hawaii.zoom.us/j/96162222366 Parameterizations of wave-ice interactions, in particular for wave attenuation due to sea ice, are needed to improve the capabilities of spectral wave forecasting models in applications to the polar regions. For this purpose, a linear continuum model is proposed based on a two-layer formulation where the floating sea ice is described as a poro-visco-elastic medium and the underlying ocean is viewed as a
Experimental and numerical investigation on the runup of leading-depression N-waves
Zoom Meeting ID: 961 6222 2366 Passcode: OREseminarDr. Peter Lo, Assistant Professor Department of Engineering Science and Ocean Engineering National Taiwan University Location Information **This seminar will be held over Zoom only** Meeting ID: 961 6222 2366 Passcode: OREseminar https://hawaii.zoom.us/j/96162222366 Solitary waves, widely used benchmark waves in hydrodynamic studies, had historically been implied as a suitable wave form for tsunamis. However, modern tsunami records reveal solitary waves to be an inaccurate model for real tsunamis. For example, before the arrival of a tsunami at shore, a significant recession of water is often observed. Solitary waves are incapable of capturing this drawdown phenomenon, and the leading-depression N-waves (LDNs)
The effect of water wave conditions and geometrical parameters of a fixed Oscillating Water Column Wave Energy Converter on its hydrodynamic performance
Watanabe 112 2505 Correa Rd, Honolulu, HI, United StatesDr. Ayrton Alfonso Medina Rodriguez Postdoctoral Researcher Applied Research Laboratory and Department of Ocean and Resources Engineering University of Hawaiʻi at Mānoa Location Information **This seminar will be held both in person (Watanabe Hall 112) and over Zoom** Meeting ID: 961 6222 2366 Passcode: OREseminar https://hawaii.zoom.us/j/96162222366 In order to achieve maximum pneumatic power in an Oscillating Water Column (OWC) device, it is crucial for the chamber to operate as close to the resonance condition as possible. This means that the frequency of the incident wave must match the resonant frequency of the converter. This resonant frequency is influenced not only
Advancements in passive acoustic monitoring: A framework for automated tracking of marine mammals

Using a variety of sensors and array configurations, PAM can provide insights into species identity, movements, behaviors and abundance of populations, and is thus an invaluable tool for assessing and monitoring populations. With the advancement of
