Maerl - History

History

Maerl has been extracted for centuries mainly for use as an agricultural fertilizer. The amount extracted increased in the late 20th century and in 2000, maerl was extracted at ∼5,000 tonnes per year in Ireland and ∼500,000 tonnes per year in France. Large scale maerl extraction over the past 40 years has removed and degraded maerl beds. In Cornwall, England, maerl has been extracted since 1970’s, but was banned in 2005 by Falmouth Harbour Commissioners.

An early reference to maerl was made by John Ray in 1690 who reported it from Falmouth. In Ireland, maerl is extracted from subfossil beds in Bantry Bay by Celtic Sea Minerals . The maerl-forming species Lithothamion corallioides and Phymatolithon calcareum are listed in Annex V of the EC Habitats Directive .

Famous quotes containing the word history:

    Social history might be defined negatively as the history of a people with the politics left out.
    —G.M. (George Macaulay)

    The custard is setting; meanwhile
    I not only have my own history to worry about
    But am forced to fret over insufficient details related to large
    Unfinished concepts that can never bring themselves to the point
    Of being, with or without my help, if any were forthcoming.
    John Ashbery (b. 1927)

    Throughout the history of commercial life nobody has ever quite liked the commission man. His function is too vague, his presence always seems one too many, his profit looks too easy, and even when you admit that he has a necessary function, you feel that this function is, as it were, a personification of something that in an ethical society would not need to exist. If people could deal with one another honestly, they would not need agents.
    Raymond Chandler (1888–1959)
