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.
A giant "blob" of sargassum seaweed measuring 5,000 miles wide — twice the width of the continental United States — is headed for the Florida coast and already covering beaches with algae that ...
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 ...
A biologist holds clumps of dulse seaweed grown by Cascadia Seaweed in British Columbia, Canada. The company is cultivating the algae for use as a feed additive and biostimulant in agriculture ...
The brown algae include the largest and fastest growing of seaweeds. [6] Fronds of Macrocystis may grow as much as 50 cm (20 in) per day, and the stipes can grow 6 cm (2.4 in) in a single day. [13] Growth in most brown algae occurs at the tips of structures as a result of divisions in a single apical cell or in a row of such
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.
