Degradation of coastal ecosystems in the Great Barrier Reef (GBR) lagoon, Australia, has been linked with increased land-based runoff of suspended solids, nutrients and pesticides since European settlement. This study estimated the increase in river loads for all 35 GBR basins, using the best available estimates of pre-European and current loads derived from catchment modelling and monitoring. ...

Caspian Sea is the largest land locked water body in the world and has been characterized by significant relative sea-level changes since the Pliocene. The sea-level oscillations have strongly impacted the coastal areas depending on geomorphological setting. This study aims to investigate the impacts of sea level oscillations on low-lying coasts of the southeastern flank of the Caspian Sea...

Background, aim and scope In water systems, water quality and geochemical properties of sediments determine the speciation of trace metals, metal transport, and sediment-water exchange, influencing metal availability and its potential effects to biota. Studies from temperate climates have shown that iron-ore mining and tailing wastewaters, besides being a source of trace metals, usually show hi...

Total marine fisheries catches from the Exclusive Economic Zone of Benin and its coastal lagoons were estimated between 1950 and 2010. The reconstruction considered artisanal and industrial sectors and their discards, subsistence fisheries from the marine and lagoon waters including those generated by women for the first time. Small-scale catch estimates were obtained using catch per unit of ef...

A methodology associated with the simulation of tidal range projects through a coastal hydrodynamic model is discussed regarding its capabilities and limitations. Particular focus is directed towards the formulations imposed for the representation of hydraulic structures and the corresponding model boundary conditions. Details of refinements are presented that would be applicable in representin...

The aim of this study was to evaluate the deposition impact of dredged material from Patos lagoon estuary on a benthic macroinvertebrate assemblage structure in an adjacent coastal marine area. Nine sampling stations were chosen at random in the disposal area, and nine others in the same way in an adjacent control area. Samples were collected at a 19 m depth before sediment disposal (11 July 20...

The coastal wetland, Ballona Lagoon in Southern California has experienced degradation and size reduction due to urbanization. This study analyzes nitrate concentrations the lagoon identify contamination sources assess its impact. includes determining levels during high low tides wet dry seasons, establishing concentration gradients, examining relationship between salinity concentrations. were ...

This study evaluated the effect of the burrowing crab Chasmagnathus granulata on the benthic community in mudflats of the Mar Chiquita coastal lagoon (Argentina, 378 459 S, 578 269 W). A significantly higher abundance of the polychaete Laeonereis acuta was found inside the C. granulata crab bed than outside. However, L. acuta abundance decreased in summer probably due to the greater activity of...

Small-scale fisheries of lagoon-estuarine complexes (LECs) in Northwest Mexico were investigated using official landings data. Species groups found in landings were clustered into three categories according to their life cycle and habitat distribution: Lagoon-estuarine (LE), Transition zone (TZ) and Coastal (CO). Average landings were highest for LE (19,606 t yr), followed by TZ (7,234 t yr), a...

To detect changes in ecosystems due to human impact, experimental designs must include replicates at the appropriate scale to avoid pseudoreplication. Although coastal lagoons, with their highly variable environmental factors and biological assemblages, are relatively well-studied systems, very little is known about their natural scales of variation. In this study, we investigate the spatio-tem...
