Along with D. poha, blades of D. antarctica are used to make traditional pōhā bags, which are used to carry and store food and fresh water, to propagate live shellfish, and to make clothing and equipment for sports. [40] [41] [42] Pōhā are especially associated with Ngāi Tahu and are often used to carry and store muttonbird (tītī) chicks.
Nereocystis (Greek, 'mermaid's bladder') is a monotypic genus of subtidal kelp containing the species Nereocystis luetkeana. [1] Some English names include edible kelp, bull kelp, bullwhip kelp, ribbon kelp, bladder wrack, and variations of these names. [2]
Alginate, a kelp-derived carbohydrate, is used to thicken products such as ice cream, jelly, salad dressing, and toothpaste, as well as an ingredient in exotic dog food and in manufactured goods. [44] [45] [46] Alginate powder is also used frequently in general dentistry and orthodontics for making impressions of the upper and lower arches. [47]
Promising seaweed yarnmaker AlgiKnit has resurfaced after four years of fine-tuning, fund-raising and development with new digs and a first reveal of its kelp-based yarn. The Brooklyn-based ...
Species in the genus Durvillaea are also sometimes called "bull kelp", but this is just a shortening of the common name southern bull kelp. Durvillaea is a genus in the order Fucales and, though superficially similar in appearance, is not a true kelp (all of which are in the order Laminariales ).
Durvillaea bull kelp grow within intertidal and shallow subtidal areas, typically on rocky wave-exposed coastal sites. [13] D. antarctica and D. poha are intertidal, whereas D. willana is subtidal (to 6 m depths). [16] Intertidal species can grow at the uppermost limit of the intertidal zone if there is sufficient wave wash. [17]

An alternative offset would be to cultivate kelp forests. Kelp can grow at 2 feet per day, 30 times faster than terrestrial plants. Planting kelp across 10% of the oceans (4.5 x the area of Australia) could provide the same offset. Additionally, the kelp would support a fish harvest of 2 megatons per year and reduce ocean acidification. Large ...
