Observations of microwave backscatter from shoaling and breaking surface waves acquired with a shore-based, coherent-on-receive X-band marine radar are presented. The was located at the dune cliff sandy beach two breaker bars. Waves were approximately shore-normal (inclination < 10°) during study period. Consistent other studies, intensity is significantly increased ( <inline-formula xmlns:mml=...

This paper presents detailed laboratory experiments investigating the effect onshore and offshore wind conditions have on nearshore wave dynamics, including extreme winds. The were performed using monochromatic waves a linearly sloping bed. results show that delay breaking promote steep breakers, while extend surf zone flatten waves. Firstly, linear cnoïdal models used in standard formulations ...

Abstract We demonstrate that a hovering, drone-mounted laser scanner (lidar) paired with survey-grade satellite and inertial positioning system measures the wave transformation across surf zone resulting runup accuracy almost equal to stationary truck-mounted terrestrial lidar. The drone, multirotor small uncrewed aircraft (sUAS), provides unobstructed measurements by hovering above at 20-m ele...

Coarse sea salt particles are emitted ubiquitously from the ocean surface by wave-breaking and bubblebursting processes. These particles impact the atmospheric chemistry by affecting the condensation of gas-phase species and, thus, indirectly the nucleation of new fine particles, particularly in regions with significant air pollution. In this study, atmospheric particle concentrations are model...

Studies on surf zone zooplankton biodiversity and population dynamics processes remain scarce in comparison to other coastal areas. In this work, we analysed the seasonal (winter/summer) variability of assemblage structure copepod biomass distinct areas with different substrate types (sandy beaches/rocky shores) at west coast Iberian Peninsula (Portugal).
