A perspective on the future of physical oceanography

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012
The ocean flows because it is forced by winds, tides and exchanges of heat and freshwater with the overlying atmosphere and cryosphere. To achieve a state where the defining properties of the ocean (such as its energy and momentum) do not continuously ...

A low‐cost, automated, and adaptable system for field‐based measurement of pCO2, pCH4, and associated variables in groundwater

Limnology and Oceanography: Methods, EarlyView.
Abstract The Groundwater Automated Chemical Examiner (GrACE) is an automated analytical system of integrated sensors for the field‐based measurement of chemical and physical properties of groundwater. The GrACE system was designed to explore parameters influencing the dissolved concentrations of carbon dioxide (pCO2) and methane (pCH4) in groundwater ...

Simulating climate change scenarios established by the Intergovernmental Panel on Climate Change in aquatic mesocosms

Limnology and Oceanography: Methods, EarlyView.
Abstract Climate change poses a major threat to ecosystems worldwide, with temperature changes being a key driver of ecological disruption in aquatic environments due to the limited ability of many aquatic species to relocate in response. Despite advances in aquatic experimental approaches to temperature control, most studies rely on simplified warming

Evaluation of Tidal Asymmetry and Its Effect on Tidal Energy Resources in the Great Island Region of the Gulf of California

Journal of Marine Science and Engineering
Hydrokinetic tidal energy is one of the few marine renewable energy resources with sufficiently mature technology for commercial exploitation. However, several parameters affect its exploitability, such as the minimum speed threshold, ambient turbulence ...

Oil-Slick Category Discrimination (Seeps vs. Spills): A Linear Discriminant Analysis Using RADARSAT-2 Backscatter Coefficients (σ°, β°, and γ°) in Campeche Bay (Gulf of Mexico)

Remote Sensing, 2019
A novel empirical approach to categorize oil slicks’ sea surface expressions in synthetic aperture radar (SAR) measurements into oil seeps or oil spills is investigated, contributing both to academic remote sensing research and to practical ...

Using physics‐informed neural networks to quantify submarine groundwater discharge under high‐frequency tidal dynamics using heat as a tracer

Limnology and Oceanography: Methods, EarlyView.
Abstract Estimating exchange rates of submarine groundwater discharge (SGD) at high temporal resolution over extended periods remains challenging, particularly when using heat as a tracer in highly dynamic environments such as tidal systems. Currently available heat transport models struggle to accurately quantify SGD exchange rates in these settings ...

Understanding the Interdecadal Changes in the Teleconnection Pattern of the East Asian Summer Monsoon Precipitation With Concurrent ENSO

Geophysical Research Letters
Interdecadal changes in the relationship between East Asian Summer Monsoon Precipitation (EASMP) and the concurrent El Niño‐Southern Oscillation (ENSO) vary across subregions, making it challenging to holistically understand these variations and the ...

Predicting potential Arctic kelp distribution and lower‐depth biomass from seafloor irradiance

Limnology and Oceanography: Methods, EarlyView.
Abstract Kelps have an extensive distribution in Arctic coastal waters. However, quantifying their role in the Arctic food web and carbon cycle is challenged by the scarcity of documented geographical distribution, standing stocks and production. Here we present a framework based on an empirical function to predict the potential kelp distribution and ...

Investigation of the loss of sound signals in the presence of Eddy in a hypothetical area

نشریه مهندسی دریا, 2021
Marine phenomena that disturb the stratification cause oscillations in the acoustic signals. Among them, Eddies can be effective factors in mixing the ocean and create significant disturbances in the sound field.
