Abstract. [] Key Method We estimate the rates of carbon accumulation in mangrove sediments and of carbon export to the coastal seas. From the rates of litter fall and export we calculate carbon accumulating in mangrove sediments to be in the order of 23×1012 g C per year and mangrove carbon introduced into the coastal ocean to be in the order of 46×1012 g C per year. They account for about 11% of the total input of terrestrial carbon into the ocean and 15% of the total carbon accumulating in modern marine…

Mangrove production and carbon sinks: A revision of global budget estimates

Mangrove forests are highly productive but globally threatened coastal ecosystems, whose role in the carbon budget of the coastal zone has long been debated. Here we provide a comprehensive synthesis

Organic carbon dynamics in mangrove ecosystems : a review

The productivity of mangroves in northwestern Mexico: a meta-analysis of current data

Mangroves constitute highly productive ecosystems that export organic material to surrounding areas. They reach their northernmost distribution on the American Pacific coast in arid northwestern

Sediment transport and carbon sequestration characteristics along mangrove fringed coasts

Mangroves play an important role in sequestering carbon and trapping sediments. However, the effectiveness of such functions is unclear due to the restriction of knowledge on the sedimentation

Carbon dynamics and trophic relationships in a human impacted and mangrove dominated tropical estuary (Can Gio, Vietnam)

Mangrove estuaries are highly dynamic environments importing carbon originating from both the watershed and the coastal ocean to the adjacent floodplain, and exporting to the ocean a fraction of that

Organic carbon burial rates in mangrove sediments: Strengthening the global budget

Mangrove wetlands exist in the transition zone between terrestrial and marine environments and as such were historically overlooked in discussions of terrestrial and marine carbon cycling. In recent

Environmental Geochemistry of Surface sediments around the mangrove Forests of the Manakudy estuary, Southwest coast of India

The mangrove ecosystems are highly productive intertidal forests distributed along the tropical coast and they stabilize the coastal zone from erosion and act as a buffer zone between land and sea. A



Carbon sinks in mangroves and their implications to carbon budget of tropical coastal ecosystems

Nearly 50% of terrigenous materials delivered to the world's oceans are delivered through just twenty-one major river systems. These river-dominated coastal margins (including estuarine and shelf

The role of sediment microorganisms in the productivity, conservation, and rehabilitation of mangrove ecosystems: an overview

This overview summarizes the current state of knowledge of microbial transformations of nutrients in mangrove ecosystems and illustrates the important contributions these microorganisms make to the productivity of the ecosystems.

Currents and Sediment Transport in Mangrove Forests

Abstract A field study of the tidal currents, cohesive sediment dynamics and transport of organic carbon in a highly vegetated mangrove swamp was carried out at Middle Creek, Cairns, Australia. The

Organic matter in sediments in the mangrove areas and adjacent continental margins of Brazil .1. Amino acids and hexosamines

The nature of sedimentary organic matter from mangroves and the continental margin of eastern Brazil (8 degrees-24 degrees S) has been investigated in order to obtain information on sources and

Role of riverine mangrove forests in organic carbon export to the tropical coastal ocean: A preliminary mass balance for the Fly Delta (Papua New Guinea)

A preliminary mass balance for organic carbon in the Fly Delta was constructed to determine the quantity and source of organic matter exported to the adjacent Gulf of Papua and Coral Sea. Total

Inorganic sediment budget in the mangrove-fringed Fly River Delta, Papua New Guinea

Six oceanographic moorings were maintained for 8 weeks across the mouth of the mangrove-fringed Fly River estuary from April to June 1995 in the southeast trade wind season. A further 4 moorings were
