A comparison of biomonitoring methodologies for surf zone fish communities. [PDF]

open access: yesPLoS ONE, 2023
Surf zones are highly dynamic marine ecosystems that are subject to increasing anthropogenic and climatic pressures, posing multiple challenges for biomonitoring.

Wave-Induced Distribution of Microplastic in the Surf Zone [PDF]

open access: goldFrontiers in Marine Science, 2020
In this study, the wave-induced distribution of 13 microplastic (MP) samples of different size, shape, and density was investigated in a wave flume with a sandy mobile beach bed profile.

Quantifying Optically Derived Two-Dimensional Wave-Averaged Currents in the Surf Zone

open access: yesRemote Sensing, 2021
Complex two-dimensional nearshore current patterns are generated by feedbacks between sub-aqueous morphology and momentum imparted on the water column by breaking waves, winds, and tides.

Shortwave Sand Transport in the Shallow Surf Zone. [PDF]

open access: yesJ Geophys Res Earth Surf, 2018
Empirical parameterizations of the shortwave sand transport that are used in practical engineering models lack the representation of certain processes to accurately predict morphodynamics in shallow water. Therefore, measurements of near‐bed velocity and

Surf Zone Turbulence and Suspended Sediment Dynamics—A Review

open access: yesJournal of Marine Science and Engineering, 2021
The existence of sandy beaches relies on the onshore transport of sand by waves during post-storm conditions. Most operational sediment transport models employ wave-averaged terms, and/or the instantaneous cross-shore velocity signal, but the models ...

Reynolds Stress in Surf Zone

open access: diamondCoastal Engineering 1984, 1984
The on-offshore and the vertical components u, w of the velocity in a surf zone on a uniformly sloping beach in a wave tank were measured simultaneously with a laser-doppler velocimeter under two conditions. The time variation of the Reynolds stress -u'w' during one wave period is discussed.

SEASONAL EVALUATION OF THE CONDITION FACTOR IN A SURF-ZONE ASSEMBLAGE FROM SOUTHEASTERN BRAZIL

open access: goldBoletim do Instituto de Pesca, 2019
The surf zone is a highly dynamic environment subject to seasonal fluctuations which could impose restrictions to the development of juvenile fish. The allometric condition factor index (K) provides a value of ‘well-being’ for fish, been used to compare ...

Environmental controls on surf zone injuries on high-energy beaches [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2019
The two primary causes of surf zone injuries (SZIs) worldwide, including fatal drowning and severe spinal injuries, are rip currents (rips) and shore-break waves. SZIs also result from surfing and bodyboarding activity.

Wave-Tracking in the Surf Zone Using Coastal Video Imagery with Deep Neural Networks

open access: yesAtmosphere, 2020
In this paper, we propose a series of procedures for coastal wave-tracking using coastal video imagery with deep neural networks. It consists of three stages: video enhancement, hydrodynamic scene separation and wave-tracking.

Composition, density and biomass of fish community from the surf zone as a function of the lunar cycle at Miramar Beach in Cabedelo, Paraíba

open access: yesNeotropical Ichthyology, 2019
The influence of the moon cycles on the ichthyofauna has been little studied in the surf zone. In this study, the number of species, density and biomass were evaluated as a function of the moon.
