Ocean Wave Powered Boats

, 2021
A brief outline of a feasibility study based on computer modeling of an ocean wave powered boat is presented. The boat consists of a main vessel and a trailing float with attached beams that are connected to the sides of the main vessel hull by revolute joints. The computer model is based on a Lagrangian formulation subject to the constraints of motion

Phase‐Resolved Attribution of Tropical Cyclone Cold Wakes From an Interpretable Data‐Driven Model

Journal of Geophysical Research: Machine Learning and Computation
Tropical cyclones (TCs) generate pronounced sea surface cooling through multiscale air‐sea interactions, yet predicting its full evolution and identifying the governing mechanisms remain challenging. Here we develop TC‐Net, an interpretable deep learning

A Maluku Sea intermediate western boundary current connecting Pacific Ocean circulation to the Indonesian Throughflow

Nature Communications, 2022
Here the authors use in situ mooring data in the Maluku Channel and the Lifamatola Passage of the Indonesian seas to show that a western boundary current transports Antarctic water from the South Pacific to the Indian Ocean.

Satellite Investigation of Semidiurnal Internal Tides in the Sulu-Sulawesi Seas

Remote Sensing, 2021
The mode-1 semidiurnal internal tides that emanate from multiple sources in the Sulu-Sulawesi Seas are investigated using multi-satellite altimeter data from 1993–2020.

Suppressed Changes of the Makassar Strait Throughflow During the 2020–2023 “Triple‐Dip” La Niña by Indian Ocean Winds

Geophysical Research Letters
As a crucial component of global ocean circulation, the Indonesian Throughflow (ITF) is modulated by the El Niño‐Southern Oscillation. While multi‐year La Niña events often greatly enhance the volume transport of the ITF, the 2020–2023 La Niña caused ...

Seasonal Link Between Deepwater Overflow Through the Luzon Strait and Deep Western Boundary Current in the Philippine Sea

Geophysical Research Letters, 2023
The cold dense water from the Pacific sinks to the deep South China Sea (SCS) through the Luzon Strait, driving the abyssal and overturning circulations in the SCS, and affecting the Indonesia Throughflow and its associated heat and freshwater fluxes ...

Observed Inhibited Downward Penetration of Wind‐Generated Near‐Inertial Energy in the Bering Sea

Geophysical Research Letters
Near‐inertial waves (NIWs) are energetic in the Bering Sea, but their downward propagation characteristics remain unknown. Here, we first report the penetration of near‐inertial energy generated by distinct synoptic wind forcing events using yearlong ...

A Transformer‐Based Deep Learning Model for Successful Predictions of the 2021 Second‐Year La Niña Condition

Geophysical Research Letters, 2023
A purely data‐driven and transformer‐based model with a novel self‐attention mechanism (3D‐Geoformer) is used to make predictions by adopting a rolling predictive manner similar to that in dynamical coupled models.

Increasing Heat Pile‐Up Events in the Southeast Indian Ocean Linked to Multi‐Year La Niña Conditions

Geophysical Research Letters
The southeast Indian Ocean (SEIO) has witnessed amplifying variability in the 0–700 m heat content during the past decades. More heat pile‐up (HPU) events have been observed than before, leading to increased occurrence of marine heatwaves and threats to ...
