Seasonal Metal Distribution in Ondo Coastal Sediment, Nigeria

Seasonal distribution of pharmaceuticals in marine water and sediment from a Mediterranean coastal lagoon (SE Spain).

The seasonal variations in the occurrence and distribution of pharmaceuticals were evaluated in seawater and sediment of Mar Menor lagoon from spring 2010 to winter 2011. A total of 20 pharmaceuticals in seawater and 14 in sediments were found at concentrations from low ngL(-)(1) up to 168ngL(-)(1) (azithromycin) in seawater and from low ngg(-1) up to 50.3ngg(-1) (xylazine) in sediments. Azithr...

Impact of Seasonal Hypoxia on Activity and Community Structure of Chemolithoautotrophic Bacteria in a Coastal Sediment.

Seasonal hypoxia in coastal systems drastically changes the availability of electron acceptors in bottom water, which alters the sedimentary reoxidation of reduced compounds. However, the effect of seasonal hypoxia on the chemolithoautotrophic community that catalyzes these reoxidation reactions is rarely studied. Here, we examine the changes in activity and structure of the sedimentary chemoli...

Sediment Released to Coastal Waters of Southeast Asia: Seasonal and Spatial Distributions

Coastal hypoxia and sediment biogeochemistry

The intensity, duration and frequency of coastal hypoxia (oxygen concentration <63μM) are increasing due to human alteration of coastal ecosystems and changes in oceanographic conditions due to global warming. Here we provide a concise review of the consequences of coastal hypoxia for sediment biogeochemistry. Changes in bottomwater oxygen levels have consequences for early diagenetic pathways ...

iCOASST – INTEGRATING COASTAL SEDIMENT SYSTEMS

Coastal areas in England and Wales are at greater risk of flooding and erosion than their landward equivalents. To address these hazards, over the last 20 years, a process to develop long-term Shoreline Management Plans (SMPs) has been developed (Leafe et al., 1998; Cooper et al., 2002; DEFRA, 2006). The spatial boundary of SMPs is defined by coastal cell and sub-cell boundaries (of order 10 2 ...
