Enhancing biomethane production from anaerobic digestion of Sargassum muticum
… yields from the anaerobic digestion (AD) of Sargassum muticum could improve the process energy balance and make its use during AD more economical and energetically favourable. Previous research showed that after 28 days of AD, methane yields from S. muticum were low (17% of the theoretical …

"Sump-Inlet" deployment linkage design for sargassum ocean sequestration (SOS)
Invasive floating sargassum seaweed has become a serious problem for Caribbean nations due to the blocking of fisheries and distinct rotten smell that disincentivizes tourism to these countries. The solution to this problem conceived in Luke Gray's master's thesis was to pump the sargassum to a …

Microplastic Abundance, Distribution and Impacts on Sargassum-Associated Juvenile Fishes in the Gulf of Mexico
… and ingested by small organisms. Pelagic <em>Sargassum</em>, an important habitat for larval and juvenile stages of many fish species, is found in large surface aggregations, and may provide complex structure in which microplastics become trapped. This could lead to greater risk of …

Ichthyoplankton Composition in the Loop Current and Sargassum Habitats in the Northern Gulf of Mexico
… mass between the GOM and Caribbean; and <em>Sargassum</em>, a two species assemblage of floating brown algae that is habitat for many larval and juvenile obligate and associated fishes. The objectives of this study were to characterize the density and community composition of ichthyoplankton …

Tracking Sargassum in the Caribbean: the design, deployment, and validation of a low-cost surface drifter
… designed to track and monitor the abundant Sargassum seaweed in the Caribbean. The phenomenon of the Great Atlantic Sargassum Belt (GASB), inundating coastlines in the northern equatorial Atlantic and Gulf of Mexico, has raised concerns due to its negative impacts on marine ecosystems, …

Historical Records And Current Status Of Fucales (Cystoseira and Sargassum spp.) In The Gulf of Naples
… distribution ad abundance of Cystoseira spp. and Sargassum spp. along different sectors of the Gulf of Naples in the bathymetric range between 0 and 50 m depth. Research was focused into three main objectives: 1) to assess the historical decline of Fucales the Gulf of Naples and their putative …

Assessing the Nursery-Role Function of Pelagic Sargassum for Juvenile Fishes in the Northern Gulf of Mexico
<p><em>Sargassum</em>, a genus of holopelagic brown algae, floats at the ocean’s surface using air-filled bladders and forms a complex comprised of two species, <em>S. natans</em> and<em> S. fluitans</em>. Oceanic processes (e.g., Langmuir circulation, etc.) aggregate <em>Sargassum </em>into mats …

Improving the anaerobic co-digestion of pelagic Sargassum and food waste into biogas and a bio-fertiliser using hydrothermal pre-treatment: Concept to application in the Caribbean
In recent years pelagic Sargassum has invaded the coastlines of the Caribbean region, Gulf of Mexico, Florida and West Africa. With intense expansion since 2011 due to environmental and oceanic anthropogenic changes, these brown seaweeds have negatively impacted aquaculture and the overall …

Modular auger design to prevent clogging in suction
… of clogging in suction piping meant to process sargassum seaweed. The auger supports a slurry pump-based system being designed to address sargassum blooms adversely affecting beaches in the Caribbean. By reducing clogging, the auger will prevent damage to the pump and reductions in productivity. …

Early Life History of <i>Prognichtys occidentalis</i> and <i>Caranx crysos</i> Associated With <i>Sargassus</i> Habitat in the Northcentral Gulf of Mexico
<p>Pelagic Sargassum and associated fronts provide an important combination of enhanced biological production and structural habitat in oceanic environments. Fronts are regions of convergence between two water masses and often provide enhanced prey densities for juvenile fishes. The present study …

Acclimating across healthy and degraded reefs
… species -Epinephelus merra (a small grouper) and Sargassum polycystum C. Agardh (a brown macroalga)- which are found in both fished and protected reefs, to investigate this plastic response and understand how these species cope in healthy versus degraded environments. We found that the fish E. …

The role of brown algal cell walls in morphogenesis and development
… In two brown algal model systems: the Sargassum muticum apex and the Fucus serratus embryo, I have used a combination of imaging techniques, growth analyses, surgical and pharmacological treatments, as well as molecular, biochemical and mechanical approaches to characterise the growth …
