Abstract Mangroves and saltmarshes are biogeochemical hotspots storing carbon in sediments the ocean following lateral export (outwelling). Coastal seawater pH is modified by both uptake of anthropogenic dioxide natural processes, e.g., wetland inputs. Here, we investigate how mangroves influence coastal carbonate chemistry quantify contribution alkalinity dissolved inorganic (DIC) outwelling to blue budgets. Observations from 45 16 worldwide revealed that >70% intertidal wetlands more...
Abstract. Ocean acidification, a complex phenomenon that lowers seawater pH, is the net outcome of several contributions. They include dissolution increasing atmospheric CO2 adds up with dissolved inorganic carbon (dissolved CO2, H2CO3, HCO3−, and CO32−) generated upon mineralization primary producers (PP) organic matter (DOM). The aquatic processes leading to are substantially affected by increased DOM nutrients via terrestrial runoff, acidic rainfall, PP algal blooms, nitrification,...
Abstract The fugacity of CO 2 ( f (water)) and air‐water flux were compared between a river‐dominated anthropogenically disturbed open estuary, the Hugli, comparatively pristine mangrove‐dominated semiclosed marine Matla, on east coast India. Annual mean salinity Hugli Estuary (≈7.1) was much less to Matla (≈20.0). All stations highly supersaturated with (annual ~ 2200 µatm), whereas marginally oversaturated 530 µatm). During postmonsoon season, outer station under saturated respect acted as...
Mangrove, seagrass, and coral habitats often lie adjacent to each other in the tropics subtropics. Lateral carbon fluxes their consecutive effects on CO2 dynamics air-water along ecosystem continuum are overlooked. We measured partial pressure of water associated biogeochemical parameters with a high temporal resolution estimated continuum. Their lateral were by using mass-balance model. The results showed that waters surrounding mangrove, acted as strong, moderate, weak source atmospheric...
ABSTRACT While seagrass ecosystems are acknowledged for their role as blue carbon sinks, significant uncertainties remain regarding the sequestration of sediment inorganic (SIC) and its broader implications cycling. These knowledge gaps hinder a comprehensive assessment contribution to global budget. To address this gap, drivers sources SIC in nine tropical Indo‐Pacific were analyzed using partial least squares path modeling oxygen isotopes binding Bayesian mixing models. We found that...
Mangroves are active carbon sequesters playing a crucial role in coastal ecosystems. In the present study, aboveground biomass (AGB) was estimated 5-year-old Avicennia marina plantation (approximate area ≈190 ha) of Indian Sundarbans using high-resolution satellite data order to assess its sequestration potential. The reflectance values each band LISS IV and vegetation indices, viz., normalized difference index (NDVI), optimized soil adjusted (OSAVI), transformed (TDVI), derived from data,...
The total blue carbon stock of the Bangladesh Sundarban mangroves was evaluated and probable future status after a century predicted based on recent trend changes in last 30 years implementing hybrid model Markov Chain Cellular automata. At present 36.24 Tg C 54.95 are stored above-ground below-ground compartments respectively resulting 91.19 C. According to prediction 15.88 would be lost from this region by year 2115. low saline species composition classes dominated mainly Heritiera spp....
Abstract Reduction in riverine freshwater supply due to climate change as well anthropogenic activities are documented throughout the globe. How river discontinuity upstream reaches and subsequent reduction influx alter inorganic organic carbon dynamics downstream estuaries adjacent mangroves has been rarely reported. We investigated of system matter (OM) two Indian near mangroves; Matla Estuary was reduced that Dhamra uninterrupted. Seasonal sampling conducted over an annual cycle. used...
The present paper dealt with the annual dynamics of absorption coefficient chromophoric dissolved organic matter at 440 nm {aCDOM(440)} during February 2015 to January 2016 in continental shelf northern Bay Bengal (nBoB) for first time. Sea surface salinity (SSS), chlorophyll-a (Chl-a), total suspended (TSM) were also analyzed. It was hypothesized that CDOM should exhibit significant spatial and temporal variability this region. aCDOM(440) spectral slope ranged between 0.1002 m−1–0.6631 m−1...
Abstract Estuaries and coastal waters are generally significant emitters of CO 2 to the atmosphere. Globally, submarine groundwater discharge (SGD) is a driver inorganic carbon dynamics partial pressure in water [ p (water)] estuaries waters. However, there few studies emission SGD large tropical estuaries. To investigate drivers (water) two India, Hooghly Matla estuaries, we conducted coupled radon surveys surface We also collected high‐temporal‐resolution (1 min) data related...
