Spatiotemporal Prediction of Tidal Currents Using Gaussian Processes [PDF]
Journal of Geophysical Research: Oceans, 2019 AbstractPredicting fast tidal currents can be a challenging task. Unlike tidal water levels, currents can vary sharply over short distances. The classical approach of harmonic analysis can analyze data at point locations and there is a need for a method that can handle spatiotemporal data, as well as be robust to the uncertainty and noise inevitable in

Predicting Tidal Currents Using 25-h Observations through a Complete Tidal Species Modulation with Tidal Current Constant Corrections Method [PDF]
Journal of Atmospheric and Oceanic Technology, 2018 AbstractA new approach enabling the prediction of tidal currents, for observation sites with as little as ≥25 h of data, has been developed as a practical way of utilizing very short tidal current records. We name this technique the complete tidal species modulation with tidal current constant corrections (CTSM+TCCC) method. In addition to a short-term

Prediction of tidal currents using Bayesian machine learning [PDF]
Ocean Engineering, 2018 Abstract We propose the use of machine learning techniques in the Bayesian framework for the prediction of tidal currents. Computer algorithms based on the classical harmonic analysis approach have been used for several decades in tidal predictions, however the method has several limitations in terms of handling of noise, expressing uncertainty ...

Prediction of tidal-driven currents using convolutional neural network
Journal of Physics: Conference Series, 2022 Abstract Efficient forecasting models of coastal currents are required for the predictive control of smart vessels with autonomous or remote operating capabilities. Accurate physics-based numerical models demand computational resources that often are unavailable onboard ships; moreover, internet bandwidth at remote locations might not be

Estimation of skew surge uncertainties when predicting tides in the past
Weather and Climate Extremes, 2023 The study of storm surges and more generally of extreme events is a subject of growing interest in the current context of coastal risk management in a changing climate. Recent studies show that the consideration of past events improves statistical models.

Tidal Currents in Douglas Channel, British Columbia: Evaluation and Prediction
Water, 2023 Douglas Channel is the principal shipping route between the town of Kitimat and the Pacific Ocean. Prediction of near-surface currents is crucial for safe tanker navigation and cleaning-up oil spills. Three years of current velocity data were collected at two moorings located 30 km apart.

What can seabirds tell us about the tide? [PDF]
Ocean Science, 2018 Small global positioning system (GPS) trackers are now routinely used to study the movement and behaviour of birds at sea. If the birds rest on the water they become “drifters of opportunity” and can be used to give information about surface currents. In

Tides and Tidal Currents—Guidelines for Site and Energy Resource Assessment
Energies, 2021 The main aim of this paper was to classify and to analyze the expeditious resource assessment procedure to help energy planners and system designers dealing with tides and tidal currents. Depending on the geographical features of the site to be evaluated,
