Seaweed aquaculture, the fastest-growing component of global food production, offers a slate opportunities to mitigate and adapt climate change. farms release carbon that maybe buried in sediments or exported deep sea, therefore acting as CO2 sink. The crop can also be used, total part, for biofuel with potential mitigation capacity, terms avoided emissions from fossil fuels, about 1500 tons km-2 year-1. aquaculture help reduce agriculture, by improving soil quality substituting synthetic...
Abstract Seagrass meadows, key ecosystems supporting fisheries, carbon sequestration and coastal protection, are globally threatened. In Europe, loss recovery of seagrasses reported, but the changes in extent density at continental scale remain unclear. Here we collate assessments from 1869 to 2016 show that 1/3 European seagrass area was lost due disease, deteriorated water quality, development, with losses peaking 1970s 1980s. Since then, rates slowed down for most species fast-growing...
Seagrasses export a substantial portion of their primary production, both in particulate and dissolved organic form, but the fate this production remains unaccounted for terms seagrass carbon sequestration. Here we review available evidence on to conclude that represents significant contribution sequestration, sediments outside meadows deep sea. The presented implies sequestration has been underestimated by only including burial within sediments.
In the 1980s, Danish coastal waters suffered from eutrophication and several nutrient management plans have been implemented during years to improve ecological status. This study aims at giving a holistic ecosystem perspective on 25 of mitigation measures. We report trends inputs responses these in various chemical biological components. Nutrient land were reduced by ~50 % for nitrogen (N) 56 phosphorus (P) since 1990. These reductions resulted significant parallel declines concentrations,...
In coastal areas around the world, dominant primary producers are benthic macrophytes, including seagrasses and macroalgae, that provide habitat structure food for diverse abundant populations communities, drive ecosystem processes. Seagrass meadows macroalgal forests economically central to human particularly in developing contributing fisheries yield, storm protection, blue carbon storage, important cultural values. These services threatened worldwide by activities, with substantial of...
Abstract Aim Macroalgal habitats are believed to be the most extensive and productive of all coastal vegetated ecosystems. In stark contrast growing attention on their contribution carbon export sequestration, understanding global extent production is limited these have remained poorly assessed for decades. Here we report a first data‐driven assessment macroalgal based modelled observed distributions net primary (NPP) across habitat types. Location Global ocean. Time period Contemporary....
Abstract Macroalgae drive the largest CO 2 flux fixed globally by marine macrophytes. Most of resulting biomass is exported through coastal ocean as detritus and yet almost no field measurements have verified its potential net sequestration in sediments. This gap limits scope for inclusion macroalgae within blue carbon schemes that support globally, understanding role their plays distal food webs. Here, we pursued three lines evidence (eDNA sequencing, Bayesian Stable Isotope Mixing...
The magnitude and distribution of net primary production (NPP) in the coastal ocean remains poorly constrained, particularly for shallow marine vegetation. Here, using a compilation situ annual NPP measurements across >400 sites 72 geographic ecoregions, we provide global predictions productivity seaweed habitats, which form largest vegetated biome on planet. We find that is strongly coupled to climatic variables, peaks at temperate latitudes, dominated by forests large brown seaweeds....
ABSTRACT This paper focuses on the marine foundation eelgrass species, Zostera marina , along a gradient from northern Baltic Sea to north‐east Atlantic. vast region supports minimum of 1480 km 2 (maximum >2100 ), which corresponds more than four times previously quantified area in Western Europe. Eelgrass meadows low salinity support highest diversity (4–6 spp.) angiosperms overall, but productivity is (<2 g dw m ‐2 d ‐1 ) and are isolated genetically impoverished. Higher areas...
Abstract Invasion of ocean surface waters by anthropogenic CO 2 emitted to the atmosphere is expected reduce seawater pH 7.8 end this century compromising marine calcifiers. A broad range biological and mineralogical mechanisms allow calcifiers cope with acidification, however these are energetically demanding which affect other processes (trade-offs) important implications for resilience organisms against stressful conditions. Hence, food availability may play a critical role in determining...
Abstract Calcium carbonates (CaCO 3 ) often accumulate in mangrove and seagrass sediments. As CaCO production emits CO 2 , there is concern that this may partially offset the role of Blue Carbon ecosystems as sinks through burial organic carbon (C org ). A global collection data on inorganic rates inorg 12% mass) revealed 0.8 TgC yr −1 15–62 ecosystems, respectively. In seagrass, correspond to an 30% net sequestration. However, a mass balance assessment highlights C mainly supported by...
