“…However, the sulphur content of S. muticum has been found to vary with season and storage [32,33]. This lower sulphur could reduce the problems of rotting Sargassum producing foul-smelling and toxic hydrogen sulphide [8,18]. The carbon content (27-29%) is similar to that reported for S. natans (28.9%) [71] but lower than that reported for S. fluitans (34.29%); however, the latter sample had a lower ash content (24%), and minerals could have leached-out [19] increasing the relative carbon content.…”

“…The beaches of the Caribbean have been experiencing increasing inundations of large masses of seaweed, primarily pelagic Sargassum (S. natans and S. fluitans) over the past decade [1][2][3][4][5][6]. These inundations have environmental [3,4,7], health [8,9] and financial implications [2,6]. The Caribbean region is highly dependent on tourism which provides over 15% of GDP and 14% of jobs, with a tourist spend of US$ 31.4 billion in 2016 [10].…”

The Caribbean has been experiencing beach inundations of pelagic Sargassum, causing environmental, health and financial issues. This study showed variations in the composition and methane potential (MP) between the species of Sargassum. The MPs for S. natans VIII, S. natans I and S. fluitans (145, 66 and 113 mL CH4 g−1 Volatile Solids) were considerably below theoretical potentials, possibly due to the high levels of indigestible fibre and inhibitors. The mixed mats Sargassum composition was substantially different from the individual species, being higher in ash, calcium, iron, arsenic and phenolics. The mixed mats produced no methane, perhaps due to the high levels of phenolics. There was a strong correlation between MP and phenolic content. Heavy metals and metalloids were at levels that should not cause concern, except for arsenic (21–124 mg kg−1 dry weight). Further work on the speciation of arsenic in Sargassum is required to fully determine the risk to health and agriculture. Both protein and lipid levels were low. The ‘indispensable amino acid’ profile compares favourably with that recommended by the World Health Organisation. Lipids had a high proportion of Polyunsaturated Fatty Acids. The use of Sargassum for biogas production could be challenging, and further work is required.

“…Sargassum is transported by ocean currents to coastal zones, and in the last 15 years, in particular in 2014-2015 (Schell et al, 2015;Hu et al, 2016), massive accumulations (100 kg wet wt/m 2 ) have been documented in bays and beaches of the Gulf of Mexico, Caribbean Islands (as well as in West African Atlantic coasts). Sargassum beachings cause economic losses to coastal fisheries and tourism, alter the dynamics of the shoreline ecosystems, and the hydrogen sulfide produced by the seaweed decomposition can also affect human health (Dabor et al, 2018;Langin, 2018). These negative impacts have fostered research to understand the factors involved in Sargassum bloom dynamics.…”

Anderson et al. Harmful Algal Bloom Observing System automated, near real-time information from nearshore and offshore sites situated in HAB transport pathways to provide improved, advanced HAB warnings; (4) merge ecological knowledge and models with existing Earth System Modeling Frameworks to enhance end-to-end capabilities in forecasting and scenario-building; (5) provide seasonal to decadal forecasts to allow governments to plan, adapt to a changing marine environment, and ensure coastal industries are supported and sustained in the years ahead; and (6) support implementation of the recent calls for action by the United Nations Decade 2010 Sustainable Development Goals (SDGs) to develop indicators that are relevant to an effective and global HAB early warning system.

“…En diciembre de 2018, un grupo de investigación sobre el sargazo publicó en The Lancet una carta en la que urgía la atención internacional sobre los efectos en la salud pública del alga en las islas del Caribe. En esta carta reportaban 11 400 casos de exposición aguda en Guadalupe y Martinica entre enero y agosto de dicho año; 3 intensiva debido a lesiones pulmonares. Se evidenció también el número de consultas relacionadas con la exposición a los gases del sargazo en descomposición.…”
