The Fudu Estuary Sandbar Lagoon is one of the most representative sandbar-lagoon landforms in China, and has undergone drastic evolution recent years, accompanied by increased coastal engineering activities. process its control factors are studied through remote sensing interpretation sediment transport calculations. During 2010–2021, sandbar quickly extended at an average speed 49.5 m/a, but a...

An abnormal embryo (male of 465 mm total length) and 13 other embryos were removed from a pregnant female bull shark (Carcharhinus leucas) caught in coastal waters between the Grijalva River Terminos Lagoon southwestern Gulf Mexico. The first record synophthalmia leucism is presented. cyclopia case reviewed.

Modern coastal environments are considered highly selective and dynamic, not only due to the natural variability of physical chemical parameters, but also because anthropogenic contamination. Our study aims identify environmental and/or factors influencing benthic foraminiferal abundances over a period one year in Tramandaí-Armazém Lagoon, southern Brazil. Assemblages were composed exclusively ...

The Vaccarès Lagoon System, located in the central part of Rhône Delta (France), is a complex shallow coastal lagoon, exposed to typical Mediterranean climate and specific hydrological regime affected by man-controlled exchanges with sea agricultural drainage channels. In this article, we report results obtained series monitoring programs, different spatial temporal resolutions. Long-term datas...

The Patos Lagoon coastal plume is a small-scale outflow that strongly controlled by meteorological tides. However, the riverine discharge of lagoon subject to high decadal variability. Hence, amount alters scale this and its effects over inner shelf environment. This study uses hydrodynamic simulations Lagrangian model estimate spreading under two different conditions.Through parameters, we cha...

Bivalves influence both the ecology and the economy of coastal regions. By filterfeeding on particles in the water column, these organisms reduce turbidity and link benthic and pelagic production. In addition, production and sales of harvested bivalves are a source of income in coastal areas like the Eastern Shore of Virginia (USA). Phytoplankton are known to be a main food source to many bival...

This study examines the effect of pH changes on photosynthetic characteristics and the role of dissolved inorganic carbon (DIC) in determining the dominance of three species of macroalgae Chaetomorpha linum (O.F. Müller) Kützing, Gracilaria verrucosa (Hudson) Papenfuss and Ulva sp. in a Mediterranean coastal lagoon. Fluctuations of pH were measured in the lagoon in summer. Water column CO(2) an...

This paper describes the building of an integrated simulation tool based on a systems approach, and its contribution to local political discussion of the mitigation of microbiological contamination of the water in a coastal area. Local management schemes view water quality as a high-priority environmental objective. In practice, how far this objective is achieved depends on trade-offs between t...
