The role of macroalgae in Blue Carbon assessments has been controversial, partially due to uncertainties about the fate of exported macroalgae. Available evidence suggests that macroalgae are exported to reach the open ocean and the deep sea. Nevertheless, this evidence lacks systematic assessment. Here, we provide robust evidence of macroalgal export beyond coastal habitats. We used metagenomes and metabarcodes from the global expeditions Tara Oceans and Malaspina 2010 Circumnavigation. We… 
Whole System Analysis Is Required To Determine The Fate Of Macroalgal Carbon: A Systematic Review
The role of marine primary producers in capturing atmospheric CO2 has received increased attention in the global mission to mitigate climate change. Yet, our understanding of carbon sequestration
Coastal darkening substantially limits the contribution of kelp to coastal carbon cycles
It is shown that increased turbidity, resulting in a 63 % reduction in light, can result in a 95% reduction in kelp productivity, and the results highlight the negative impacts of turbidity on a large source of previously unaccounted for carbon.
Carbon Sequestration in the Form of Recalcitrant Dissolved Organic Carbon in a Seaweed (Kelp) Farming Environment.
Under climate change scenarios, the contribution of macroalgae to carbon sequestration has attracted wide attention. As primary producers, macroalgae can release substantial amounts of dissolved
Environmental DNA identifies marine macrophyte contributions to Blue Carbon sediments
Estimation of marine macrophyte contribution to coastal sediments is key to understand carbon sequestration dynamics. Nevertheless, identification of macrophyte carbon is challenging. We propose
Variability in the Net Ecosystem Productivity (NEP) of Seaweed Farms
The important role of vegetated ecosystems in the sequestration of carbon has gained strong interest across a wide variety of disciplines. With evidence growing of the potential for macroalgae
A global dataset of seaweed net primary productivity
The dataset presented here provides a basis for local, regional and global comparative studies of the NPP of underwater vegetation, and is pivotal for achieving a better understanding of the role seaweeds play in the global coastal carbon cycle.
Effects of Nutrient Availability on the Release of Dissolved and Particulate Organic Carbon by Pyropia haitanensis and Its Implications
As an important component of the coastal-offshore ecosystem, Pyropia haitanensis aquaculture is continually being challenged due to rapid environmental changes because of global climate change and
Substantial blue carbon in overlooked Australian kelp forests
It is concluded that the omission of kelp forests from blue carbon assessments significantly underestimates the carbon storage and sequestration potential from vegetated coastal ecosystems globally.


Substantial role of macroalgae in marine carbon sequestration
Marine macroalgae are dominant primary producers in coastal zones. A review of the published literature suggests that macroalgae may play an important role in carbon sequestration. Vegetated coastal
The fate of marine autotrophic production
Ex- trapolation of these results to the global ocean identifies marine angiosperms, which only contribute 4% of total ocean NPP, as major contributors of the NPP stored and subsequently buried in marine sediments, to lead to estimates of total burial of marine NPP that exceed current estimates by 15-50%.
Sequestration of macroalgal carbon: the elephant in the Blue Carbon room
Because of the large carbon sink they support, incorporation of macroalgae into BC accounting and actions is an imperative, and requires a paradigm shift in accounting procedures as well as developing methods to enable the capacity to trace carbon from donor to sink habitats in the ocean.
Light availability in the coastal ocean: Impact on the distribution of benthic photosynthetic organisms and their contribution to primary production
Abstract. One of the major features of the coastal zone is that part of its sea floor receives a significant amount of sunlight and can therefore sustain benthic primary production by seagrasses,
Comparison of marine macrophytes for their contributions to blue carbon sequestration.
The results of this study show that marine macroalgae do contain refractory compounds and thus may be more valuable to long-term carbon sequestration than the authors previously have considered.
Potential export of unattached benthic macroalgae to the deep sea through wind‐driven Langmuir circulation
Carbon export to the deep sea is conventionally attributed to the sinking of open ocean phytoplankton. Here, we report a Langmuir supercell event driven by high winds across the shallow Great Bahama
Reviews and syntheses: Hidden forests, the role of vegetated coastal habitats in the ocean carbon budget
Abstract. Vegetated coastal habitats, including seagrass and macroalgal beds, mangrove forests and salt marshes, form highly productive ecosystems, but their contribution to the global carbon budget
A blueprint for blue carbon: toward an improved understanding of the role of vegetated coastal habitats in sequestering CO2
Recent research has highlighted the valuable role that coastal and marine ecosystems play in sequestering carbon dioxide (CO(2)). The carbon (C) sequestered in vegetated coastal ecosystems,
