| The coast of Tanzania is characterised by a wide diversity of biotopes and species, typical of the tropical Indowest Pacific oceans, and the peoples living there utilise a variety of its natural resources. Because of the extent of the diversity and variety, several different examples are used by this study to elucidate the complexity of issues and multiplicity of management responses related to use of coastal and marine resources. It emerges that coastal management requires an integrated cross-sectoral approach to address the wide array of interrelated issues involved. |

| Gross sedimentation rates (GSRs) were monitored together with meteorological data and the main biochemical characteristics of the collected material (i.e. organic content, C, N, total proteins, carbohydrates, lipids and available proteins) over a three year cycle at a shallow station (18 m) of the Bay of Banyuls, France. GSRs were between 0.26 (11/04/92) and 317.75 gDW m(-2) d(-1) (18/02/94). They followed an annual cycle with low and relatively constant values during spring and summer and high, variable Values during fall and winter. During the study GSRs correlated poorly (state of the sea, precipitation) or even non-significantly (wind speed) with the main meteorological parameters. GSRs correlated negatively with the organic content of the material... |

| The coastal zone and oceans surrounding Sub-Saharan Africa, with their vast resources of food, energy, and minerals, not only are composed of various fragile ecosystems, but are scenes of a variety of often conflicting uses. At present, the uncontrolled development of the coastal zone and ocean and the almost haphazard exploitation of their natural resources threaten to turn the promise of economic prosperity into an environmental nightmare that portends great dangers for present and future generations. There is the urgent need to put in place national management policies that address the environmental controls and procedures to be applied in pursuit of economic development. However, the oceans have no physical boundaries corresponding to national... |

| Surface gravity waves generated by winds are ubiquitous on our oceans and play a primordial role in the dynamics of the ocean–land–atmosphere interfaces. In particular, wind-generated waves cause fluctuations of the sea level at the coast over timescales from a few seconds (individual wave runup) to a few hours (wave-induced setup). These wave-induced processes are of major importance for coastal management as they add up to tides and atmospheric surges during storm events and enhance coastal flooding and erosion. Changes in the atmospheric circulation associated with natural climate cycles or caused by increasing greenhouse gas emissions affect the wave conditions worldwide, which may drive significant changes in the wave-induced coastal hydrodynamics.... |

| ABSTRACT To counteract the spread of the Covid-19 pandemic disease, the Colombian government decreed a quarantine period from March 24 to July 1, 2020, which forced the cessation of tourist activities and the closure of the main tourist destinations of the Colombian Caribbean: Santa Marta, Cartagena, and San Andrés. During this period, a significant increase in the environmental quality of these coastal zones was perceived. To quantify environmental changes in the coastal zone, the variation in chlorophyll concentration and total suspended solids observed by the Sentinel-3 satellite mission, 30 days before and after the start of the quarantine, was analyzed. The results showed a decrease in the concentration of chlorophyll (> 20 %) and suspended solids... |

| The main content of the new European Water Framework Directive is presented. Within its river basin management approach, a special mention of coastal waters status is made. Among the issues at stake are the setting up of river basin management plans, including coastal waters, and water quality assessment system leading to an harmonized definition of quality objectives and their appropriate indicators. The Rhone-Mediterranean-Corsica Water Master Plan, launched in 1996, is considered to be well fitted to this river basin approach and the necessary tools which go with it. It shows up how a river quality assessment system (SEQ) can be adapted to the coastal waters and how it can progressively lead to an efficient set of publishable environmental and... |

| This study focuses on assessing the state of population distribution, land cover distribution, biodiversity hotspots and protected areas in global coastal zones. The coastal zone is defined as land within 100 km of the coastline. This study attempts to answer such questions as: how crowded are the coastal zones, what is the pattern of land cover distribution in these areas, how many of these areas are designated as protected areas, and what is the state of the biodiversity hotspots. This study uses globally consistent and comprehensive geo-spatial data sets based on remote sensing and other sources. The application of modern Geographic Information System (GIS) layering methods and consistent data sets has made it possible to identify and quantify selected... |

| Understanding the nature and origins of food sources supporting coastal lagoon-inhabiting organisms is necessary to evaluate the ecological status of such ecosystems. The trophic ecology of a bivalve specie Spondylus crassisquama was studied in the Ojo de Liebre lagoon (Baja California, Mexico), combining stable isotope (SI), fatty acid (FA) and sterols analyses along a transect under oceanic influences. The second objective of the study was to investigate if sterols compositions give complementary information to those obtained from FA and SI. Temporal and spatial patterns of the three biomarkers in bivalve tissues suggest oceanic inputs at the mouth of the lagoon, while the inner station was characterized by a contribution of local sources including an... |

| Between 1987 and 1995, 93 strandings of marine mammals were recorded along the ecuadorian continental coast, including one mass stranding of 56. The strandings involved 12 species of cetaceans (10 Odontoceti and 2 Mysticeti) and one species of pinniped. The Odontoceti were represented by: bottlenose dolphin Tursiops truncatus (n=30), sperm whale Physeter macrocephalus (n=25), Pacific spotted dolphin Stenella attenuata (n=7), striped dolphin Stenella coeruleoalba (n=2), false killer whale Pseudorca crassidens (n=2), Cuvier's beaked whale Ziphius cavirostris (n=2), short finned pilot whale Globicephala macrorhynchus (n=1), short-beaked common dolphin Delphinus delphis (n=3), Risso's dolphin Grampus griseus (n=1) and pygmy killer whale Feresa attenuata (n=1).... |
