Interglacial stage

Japanese: interglacial stage（英語表記）interglacialstage

...the names of the glacial periods are derived from the names of the rivers along the Danube, starting with the oldest, and are arranged in alphabetical order: Biber, Danube, Günz, Mindel, Riss, and Würm. Interglacial periods were placed between each glacial stage, and the relative length of an interglacial period was determined from the degree of weathering, as the meltwater gravel layers of the glacial period were weathered during the interglacial period. In Northern Europe, where the Scandinavian ice sheet was located, the same river names were used, and the Elster, Saale, and Weichselian periods were named from the oldest to the newest, and the interglacial periods characterized by marine deposits were named after the Holstein and Eem periods, which are the distribution areas of the marine deposits. ...

From [Ice Age]

…The Quaternary Pleistocene glacial period, known as the glacial age, saw periods of cold weather when continental glaciers covered not only the poles but also the plains and hills of the mid-latitudes. Such periods are called glacial periods. Glacial periods alternate with interglacial stages, periods of warm weather similar to the present climate. Glacial periods are further divided into subglacial periods, which are periods of warmer weather, although temperatures were lower than today and vegetation did not recover as quickly as today. …

…それはドナウ川沿いの河川名をとり，ビーバー，ドナウ，ギュンツ，ミンデル，リス，ウルム氷期と古い方から順に，その頭文字がアルファベット順に工夫されている氷期名である。それぞれの氷期glacial stageの間に間氷期interglacial stageがおかれたが，氷期の融氷水礫層が間氷期には風化されることにより，風化の程度から間氷期の時間の相対的な長さが考えられた。スカンジナビア氷床があった北ヨーロッパでも同じように河川名を採用し，古い方からエルスター，ザーレ，ワイクセル氷期とし，その間に海成層で特徴づけられる間氷期を，海成層の分布域のホルスタイン，エームの名で区分した。…

【氷期】より

…第四紀更新世のいわゆる氷河時代には，両極のみならず中緯度の平野･丘陵部も広く大陸氷河におおわれた気候の寒冷期があり，そのような時期を氷期という。氷期は現在の気候と同等の温暖気候の時期である間氷期interglacial stageと交代をくり返している。氷期はさらに，現在にくらべれば気温は低く，植生の回復も現在ほどではないにしても温暖化した時期の亜間氷期によって亜氷期に区分される。…
