Name


'Muckle' is Scots for 'big' or 'large'; 'holm' is from the Old Norse holmr, a small and rounded islet.[4]


Geography


To the south lies Little Green Holm, and between the two is the Sound of Green Holms. Eastward is a strait called Fall of Warness between Muckle Green Holm and the much larger island of Eday.

Muckle Green Holm has a great cormorant colony and a population of European otters.[2]


Tidal power


The Fall of Warness has strong tidal currents suitable for tidal power.

Starting in 2007,[5] the European Marine Energy Centre installed tidal power testing equipment.[6]

In 2021, Orbital Marine Power installed a tidal turbine called Orbital O2 that supplies 2MW to the electrical grid.

[de] Muckle Green Holm

Muckle Green Holm ist eine heute unbewohnte Insel der Orkney in Schottland. Sie ist in etwa 28 Hektar groß und steigt bis auf 28 Meter über dem Meeresspiegel. Die wörtliche Bedeutung des Namens ist widersprüchlich. „Holm“ vom altnordischen holmr bedeutet kleine Insel. „Muckle“, ist schottisch für „groß“. So ist Muckle Green Holm eine große kleine grüne Insel. Im Süden von Muckle Green Holm liegt Little Green Holm, und zwischen beiden der Sound of Green Holms.

Muckle Green Holm è un'isola disabitata settentrionale dell'arcipelago delle Isole Orcadi, in Scozia. Si estende per circa 28 ettari e la sua altezza massima è di 28 metri sul livello del mare, dove sorge una stazione di triangolazione. Il significato letterale del nome risulta contraddittorio: "Holm" deriva dall'antico norreno holmr, che significa "isoletta piccola e rotonda".[1] "Muckle" in lingua scots significa invece "grande" o "largo", pertanto il nome completo significherebbe "piccola grande isola". A sud dell'isola sorge Little Green Holm e tra le due vi è il Sound of Green Holms. Verso est vi è uno stretto chiamato Fall of Warness, situato tra Muckle Green Holm e l'isola molto più grande di Eday. In queste acque, il Centro Europeo per l'Energia Marina ha installato strumentazione per test sull'energia mareomotrice.[2]
