SeaweedSeaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of Rhodophyta (red), Phaeophyta (brown) and Chlorophyta (green) macroalgae. Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonic algae, play a vital role in capturing carbon, producing at least 50% of Earth's oxygen. Natural seaweed ecosystems are sometimes under threat from human activity.
PorphyraPorphyra is a genus of coldwater seaweeds that grow in cold, shallow seawater. More specifically, it belongs to red algae phylum of laver species (from which comes laverbread), comprising approximately 70 species. It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans. In East Asia, it is used to produce the sea vegetable products nori (in Japan) and gim (in Korea).
Vitamin B12Vitamin B12, also known as cobalamin, is a water-soluble vitamin involved in metabolism. It is one of eight B vitamins. It is required by animals, which use it as a cofactor in DNA synthesis, and in both fatty acid and amino acid metabolism. It is important in the normal functioning of the nervous system via its role in the synthesis of myelin, and in the circulatory system in the maturation of red blood cells in the bone marrow. Plants do not need cobalamin and carry out the reactions with enzymes that are not dependent on it.
NoriNori 海苔 is a dried edible seaweed used in Japanese cuisine, made from species of the red algae genus Pyropia, including P. yezoensis and P. tenera. It has a strong and distinctive flavor, and is often used to wrap rolls of sushi or onigiri (rice balls). The finished dried sheets are made by a shredding and rack-drying process that resembles papermaking. They are sold in packs in grocery stores for culinary purposes. Since nori sheets easily absorb water from the air and degrade, a desiccant is needed when storing nori for any significant time.
Gim (food)Gim (), also romanized as kim, is a generic term for a group of edible seaweeds dried to be used as an ingredient in Korean cuisine, consisting of various species in the genera Pyropia and Porphyra, including P. tenera, P. yezoensis, P. suborbiculata, P. pseudolinearis, P. dentata, and P. seriata. Along with wakame and sweet kelp, gim is one of the most widely cultivated and consumed types of seaweed in Korea. The dried sheets of gim are often rolled to wrap and be eaten with rice.
Bristol ChannelThe Bristol Channel (Môr Hafren, literal translation: "Severn Sea") is a major inlet in the island of Great Britain, separating South Wales (from Pembrokeshire to the Vale of Glamorgan) and South West England (from Devon, Somerset to North Somerset). It extends from the smaller Severn Estuary of the River Severn (Afon Hafren) to the North Atlantic Ocean. It takes its name from the English city and port of Bristol Long stretches of both sides of the coastline are designated as Heritage Coast.
