Leatherback sea turtles (Dermochelys coriacea) nest on dynamic, erosion-prone beaches. Erosive processes and resulting nest loss have long been presumed to be a hindrance to clutch survival. In order to better understand how leatherbacks cope with unstable nesting beaches, I investigated the role of beach erosion in leatherback nest site selection at Playa Gandoca, Costa Rica. I also examined t...

Unique oil:sand aggregates, termed surface residue balls (SRBs), were formed on coastal headland beaches along the northern Gulf of Mexico as emulsified MC252 crude oil mixed with sand following the Deepwater Horizon spill event. The objective of this study is to assess the biodegradation potential of crude oil components in these aggregates using multiple lines of evidence on a heavily-impacte...

Enterococci are used to assess the risk of negative human health impacts from recreational waters. Studies have shown sustained populations of enterococci within sediments of beaches but comprehensive surveys of multiple tidal zones on beaches in a regional area and their relationship to beach management decisions are limited. We sampled three tidal zones on eight South Florida beaches in Miami...

In mid-winter in a temperate area, untreated municipal sewage overflowed onto ocean beaches. To assess the infection risk posed to beachgoers by sewage-borne pathogens, we developed a framework to predict the concentration of pathogens in beach sand, and coupled the environmental concentration to sand-exposure parameters and dose-response relationships for representative sewage-borne pathogens....

eighteen kilometers long coastal stretch from the new mangalore port in the north totalapadi in the south has been studied in order to understand shoreline changes and erosion/ accretion patterns that have taken place due to the natural processes and anthropogenic activities. shoreline changes and quantification of beach erosion/accretion were made using the survey of india topomap, multidated ...

Microplastics' (particles size ≤5 mm) sources and fate in marine bottom and beach sediments of the brackish are strongly polluted Baltic Sea have been investigated. Microplastics were extracted using sodium chloride (1.2 g cm-3). Their qualitative identification was conducted using micro-Fourier-transform infrared spectroscopy (μFT-IR). Concentration of microplastics varied from 25 particles kg...
