Seaweed is lifted out of the top of an algae scrubber/cultivator, to be discarded or used as food, fertilizer, or skin care. Alginates are used in industrial products such as paper coatings, adhesives, dyes, gels, explosives and in processes such as paper sizing, textile printing, hydro-mulching and drilling.
A very large algae bloom in Lake Erie, North America, which can be seen from space. An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in fresh water or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. [1]
Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
The gas seaweed releases when it rots — hydrogen sulfide — can irritate your eyes, nose and throat. Tiny sea creatures living in the seaweed, like jellyfish and sea lice, can also cause skin ...
The seaweed can choke corals, wreak havoc on coastal ecosystems and diminish air quality. A sargassum bloom floats between the Gulf of Mexico and West Africa. The seaweed can choke corals, wreak ...
Once the seaweed begins to rot, it releases a substance called hydrogen sulfide, which gives off an unpleasant odor similar to rotting eggs. While it may be smelly, for the most part sargassum isn ...
The adults detect the scent of the seaweed and lie their eggs in the decaying algae. The seaweed's particular environment allows the eggs to hatch, and the larvae begin to burrow into the seaweed. The brown and green algae preferred by C. frigida are usually of either the genus Lamniaria or the genus Fucus.
Laminaria hyperborea is a massive, leathery seaweed, up to 360 cm long. [3] The holdfast is large and cone-shaped, with branched rhizoids, looking rather like a bird's foot. The stipe is circular in cross section, rough, thick at the base and tapering upwards. Older stipes are often covered with epiphytic red algae. The laminate blade is deeply ...
