TLDR
The unaccounted carbon sink is conservatively estimated at 112 ± 85 Tg C a 1, equivalent in magnitude to 30-40% of the global riverine organic carbon input to the coastal zone.
Abstract
results in a conservative estimate of 218 ± 72 Tg C a 1 . When using the best available estimates of various carbon sinks (organic carbon export, sediment burial, and mineralization), it appears that >50% of the carbon fixed by mangrove vegetation is unaccounted for. This unaccounted carbon sink is conservatively estimated at 112 ± 85 Tg C a 1 , equivalent in magnitude to 30–40% of the global riverine organic carbon input to the coastal zone. Our analysis suggests that mineralization is severely underestimated, and that the majority of carbon export from mangroves to adjacent waters occurs as dissolved inorganic carbon (DIC). CO2 efflux from sediments and creek waters and tidal export of DIC appear to be the major sinks. These processes are quantitatively comparable in magnitude to the unaccounted carbon sink in current budgets, but are not yet adequately constrained with the limited published data available so far.

Mangroves among the most carbon-rich forests in the tropics

TL;DR: In this article, the authors quantified whole-ecosystem carbon storage by measuring tree and dead wood biomass, soil carbon content, and soil depth in 25 mangrove forests across a broad area of the Indo-Pacific region.

Tidal wetland stability in the face of human impacts and sea-level rise

TL;DR: Whether wetlands continue to survive sea-level rise depends largely on how human impacts interact with rapid sea- level rise, and socio-economic factors that influence transgression into adjacent uplands.

Carbon Cycling and Storage in Mangrove Forests

TL;DR: Of immediate concern are potential carbon losses to deforestation that are greater than these ecosystems' rates of carbon storage, and large reservoirs of dissolved inorganic carbon in deep soils are a large loss of carbon.

Estuarine and Coastal Ocean Carbon Paradox: CO2 Sinks or Sites of Terrestrial Carbon Incineration?

TL;DR: It is demonstrated here that CO2 release in estuaries is largely supported by microbial decomposition of highly productive intertidal marsh biomass, thus leading to more dissolved inorganic carbon export to the ocean.

The value of the world's ecosystem services and natural capital

TL;DR: In this paper, the authors have estimated the current economic value of 17 ecosystem services for 16 biomes, based on published studies and a few original calculations, for the entire biosphere, the value (most of which is outside the market) is estimated to be in the range of US$16-54 trillion (10^(12)) per year, with an average of US $33 trillion per year.

Present state and future of the world's mangrove forests

TL;DR: In this article, the authors show that over the past 50 years, approximately one-third of the world's mangrove forests have been lost, but most data show very variable loss rates and there is considerable margin of error in most estimates.

Mangrove forests: one of the world's threatened major tropical environments.

TL;DR: In this article, Saenger et al. reviewed the status of mangrove swamps worldwide and assessed the effect of human activities on mangroves in the coastal environment using satellite imagery.
