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
- Investigating plan-view asymmetry in wave-influenced deltas
ABSTRACT: We investigate the asymmetrical development of deltas in terms of a high-angle-wave instabil-ity in the shape of a shoreline due to breaking-wave driven alongshore sediment transport Demonstrating the strong wave-angle dependence of shoreline evolution, numerical modeling suggests that the characteristics of the wave climate can play an integral role in the morphological evolution

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)
- 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

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
- Scientists Urge Protection of World’s Deltas
Scientists call for maintenance efforts to be started now to avert the loss of vast expanses of coastline, and the consequent losses of ecological services, economic and social crises, and large-scale migrations
