Simulation and risk assessment of oil spill adsorption along complex coastlines in multi-island areas
Oil spills in complex, multi-island coastal regions demand more accurate risk assessment. Traditional models often oversimplify shoreline interactions, assuming infinite absorption. This study introduces a dynamic adsorption-desorption mechanism within the SCHISM model, incorporating substrate-specific oil retention and release rates across bedrock, gravel, tidal flats, and artificial shorelines. Numerical experiments demonstrate a realistic rise-and-fall evolution of surface oil, influenced significantly by substrate type.
Benthic life stages retain fjord-scale population structure despite pelagic dispersal
Understanding population structure in marine organisms with complex life cycles presents a significant ecological challenge. A recent study published by World Data Ocean investigated this dynamic in the scyphozoan jellyfish *Aurelia aurita* within a fjord system, combining genetic analyses, field observations, and hydrodynamic modeling. Findings reveal that despite high dispersal potential, benthic polyp populations maintain consistent genetic diversity, acting as a reservoir for the more variable pelagic medusa stage.
Hurricane induced spatial and temporal variation in salinity in a semi-enclosed subtropical Estuarine Bay
Hurricane Irma (2017) significantly impacted South Florida, yet the subsequent spatiotemporal salinity variations within Biscayne Bay remain poorly understood. This study utilizes validated numerical simulations to quantify the relative contributions of canal discharge and rainfall to these changes. Results indicate canals drove up to 90% of shoreline salinity shifts, while rainfall dominated deeper waters. Furthermore, Lagrangian particle tracking revealed wind-driven flushing, with easterly winds accelerating water expulsion and inducing spatially variable stratification within the bay.
