Weekend #Plankton Factoid 🦠🦐
Since 2011, millions of tons of a brown algae called Sargassum has washed onto beaches in the Caribbean. The rotting seaweed releases toxic hydrogen sulfide, smelling of rotten eggs, impacting tourism and shore access. It was initially thought Saharan iron dust was the cause, but new #science

Time-domain pressure and surface wave propagation over generic topography due to sea floor motion
The surface gravity wave evolution, imitating tsunamis triggered by the ocean floor's arbitrary temporal motion over a generic seafloor topography, is investigated using the linearised water wave theory of a compressible ocean. The unprecedented details of pressure wave bounce between the water surface and ocean floor, followed by the generation of acoustic-gravity wave (AGW) propagation away from the initial disturbance, are shown for the first time. The computational novelty covers accurate p…
