Kelp

Kelps are large seaweeds (algae) belonging to the brown algae (Phaeophyceae) in the order Laminariales. There are about 30 different genera.

Kelp grows in "underwater forests" (kelp forests) in shallow oceans, and is thought to have appeared in the Miocene, 23 to 5 million years ago. The organisms require nutrient-rich water with temperatures between 6 and 14 °C (43 and 57 °F). They are known for their high growth rate — the genera Macrocystis and Nereocystis can grow as fast as half a metre a day, ultimately reaching 30 to 80 metres (100 to 260 ft).

Through the 19th century, the word "kelp" was closely associated with seaweeds that could be burned to obtain soda ash (primarily sodium carbonate). The seaweeds used included species from both the orders Laminariales and Fucales. The word "kelp" was also used directly to refer to these processed ashes.

Description

In most kelp, the thallus (or body) consists of flat or leaf-like structures known as blades. Blades originate from elongated stem-like structures, the stipes. The holdfast, a root-like structure, anchors the kelp to the substrate of the ocean. Gas-filled bladders (pneumatocysts) form at the base of blades of American species, such as Nereocystis lueteana, (Mert. & Post & Rupr.) to hold the kelp blades close to the surface.

    Autumn

    by: Kalle Baah

    This ya thing I wanna say
    Wouldn't throw my love away
    I'm coming with the tide
    So I never gonna ride off on a side
    This is my chariot
    My lonely days are gone
    This is my chariot
    I never gonna blow it once again
    Or twice, no nice, cause your eyes is my price
    I'm coming with the autumn
    I'm coming with the autumn wind
    I'm coming with the autumn
    I'm coming with the autumn wind
    Pick down the apple from the tree
    It's charity for you and me
    The autumn wind blow chilly and cold
    And you are the one that I wanna hold
    Please take your stand and come with me
    Cast your spell and set us free
    From ball and chain
    And then we know which way to go
    I'm coming with the autumn
    I'm coming with the autumn wind
    I'm coming with the autumn
