[1] Total alkalinity (AT) was measured during the Meteor 51/2 cruise, crossing the Mediterranean Sea from west to east. AT concentrations were high ( 2600 mmol kg ) and alkalinity-salinity-correlations had negative intercepts. These results are explained by evaporation coupled with high freshwater AT inputs into coastal areas. Salinity adjustment of AT revealed excess alkalinity throughout the ...

Sedimentation and erosion processes can be influenced by hydro-oceanographic factors. These factors include waves, currents, tides because they interact directly with the coastal/coastal area. Related to these problems, sedimentation is one thing that needs studied. One way used in providing information about widely use a hydrodynamic model. Based on this, it seen important conduct research det...

Tropical cyclones affect the Gulf of Mexico coastline annually; however, the historical record of these events is limited to about 400 years. To establish the occurrence frequency and the importance of cyclones in creating strata, this record needs to be validated by examining coastal sediments for preservation potential of storm bedding. St. Vincent Island National Wildlife Refuge is located i...

[1] Sediment flux from rivers to oceans is the fundamental driver of fluvio-deltaic morphodynamics and continental margin sedimentation, yet sediment transport across the river-to-marine boundary is poorly understood. Coastal rivers typically are affected by backwater, a zone of spatially decelerating flow that is transitional between normal flow upstream and the offshore river plume. Flow dece...

-Local characteristics in the upwelling of Galicia (NW Iberian Peninsula) are studied in terms of dissolved silicate patterns in the seawater column and opal distribution in the sediments. Freshwater input, upwelling, remineralization and sedimentation are considered. The freshwater silicate input is not important during the upwelling season. Upwelling is the main process controlling silicate b...

Introduction Degradation of the world's coral reefs is one of the most vivid examples of the effects of global environmental damage of marine ecosystems. The major stressors responsible for coral reef decline have been attributed to coastal urban and industrial development, agricultural activity, sedimentation, overharvesting, marine pollution, disease and climate change Reef species experienci...
