  • Rivers, Estuaries, Deltas - Woods Hole Oceanographic Institution
    Rivers, estuaries, and deltas are key to understanding the chemical structure of seawater, and are home to some of the world's most diverse ecosystems
  • Rivers, Estuaries, Deltas - Woods Hole Oceanographic Institution
    Stretching from inland rivers and bays to the edge of the continental shelf, the coastal ocean accounts for about 10 percent of the ocean's surface area Yet this relatively small sliver of ocean contains about half of all the microscopic plants adrift in our seas
  • For now, river deltas gain land worldwide - Woods Hole Oceanographic . . .
    Delta areas worldwide have gained land in the past 30 years, despite river damming Recent land gains are unlikely to last due to expected sea-level rise

    WAVE INFLUENCE ON DELTAS— IMPLICATIONS FOR THE DANUBE DELTA On the basis of a survey of the morphology of several deltas and or deltaic lobes, Bhattacharya and Giosan (2003) introduced a conceptual model for wave-influenced deltas that classifies them into symmetric, asymmetric, and deflected types (Fig 5)
  • Brackish Water: Where Fresh Water Rivers Meet A Salt Water Sea
    In this issue of Oceanus, we talk about the science behind brackish water and estuaries Learn about the transitions of salt water to fresh water
  • The Once and Future Danube River Delta
    The traditional understanding of deltas holds that the river carries all the mud and sand deposited at the river mouth But Giosan questioned this old assumption, and he and his colleagues are showing that not all the sediment is brought by the river
  • Wave-influenced deltas: geomorphological implications for facies . . .
    A process-based facies model for asymmetric wave-influenced deltas predicts significant river-borne muds with potentially lower quality reservoir facies in prodelta and downdrift areas, and better quality sand in updrift areas Many ancient barrier-lagoon systems and ‘offshore bars’ may be better reinterpreted as components of large-scale asymmetric wave-influenced deltaic systems The
  • Significant effect of sediment cohesion on delta morphology
    Douglas A Edmonds1* and Rudy L Slingerland2 The morphologies of the world’s deltas are thought to be determined by river discharge, tidal range and wave action1 More recently, sea-level rise2,3 and human engineering4 have been shown to shape delta evolution The effects of factors such as sediment type and the overall amount of sediment carried by rivers are considered secondary4–6 In

    INTRODUCTION Deltas are amongst the most environmentally and economi-cally important coastal sedimentary environments Twenty-one of the world’s 25 largest rivers, which deliver 31% of total fluvial sediment reaching the ocean, have well-expressed deltas developed at the open coast (Milliman and Meade, 1983; Meade, 1996) Deltas have high natural and agricultural productivity, rich
