Marine isotope stages (MIS), marine oxygen-isotope stages, or oxygen isotope stages (OIS), are alternating warm and cool periods in the Earth's paleoclimate, deduced from oxygen isotope data reflecting changes in temperature derived from data from deep sea core samples. Working backwards from the present, which is MIS 1 in the scale, stages with even numbers have high levels of oxygen-18 and represent cold glacial periods, while the odd-numbered stages are lows in the oxygen-18 figures, representing warm interglacial intervals. The data are derived from pollen and foraminifera (plankton) remains in drilled marine sediment cores, sapropels, and other data that reflect historic climate; these are called proxies.

  • La chronologie isotopique est fondée sur les variations des températures moyennes de la planète au cours du temps, déduites des proportions des isotopes 16O et 18O de l'oxygène (stades isotopiques de l'oxygène ou SIO) trouvées dans les carottages océaniques et glaciaires réalisés par les chercheurs. Valable à l'échelle planétaire, elle se substitue aujourd'hui aux chronologies locales fondées sur les périodes glaciaires traditionnelles. Dans la littérature, elle est généralement signifiée par les initiales anglaises « MIS » (Marine isotope stage). (fr)
  • Uno stadio isotopico marino (o MIS, dall'inglese Marine Isotope Stages), o più compiutamente stadio dell'isotopo marino dell'ossigeno, è uno dei periodi alternati caldi e freddi del clima terrestre, dedotti dalle variazioni del rapporto tra gli isotopi 16O e 18O dell'ossigeno presenti nei sedimenti fossili ottenuti da carotaggi di sedimenti estratti dai fondali marini.

  • 海洋酸素同位体ステージ(かいようさんそどういたいステージ、英:Marine oxygen Isotope Stage, MIS)は、天然に存在する酸素の同位体の比による過去の気温に基づいたステージ区分。 海底に連続して堆積した堆積物をボーリングし、サンプリングされた深海底ボーリングコア中の有孔虫の殻の酸素同位体比率から、古海洋水温の変動を推測、構成する。 (ja)
  • Een Marine Isotope Stage, (Engels voor: mariene isotopen-etage); acroniem: MIS, is een onderverdeling in de chronostratigrafie, gebaseerd op grond van de veranderingen in de verhouding tussen lichte en zware isotopen van zuurstof, zoals die wordt aangetroffen in kalkige fossielen uit diepzeekernen. Deze stratigrafie wordt ook wel de oceaanstratigrafie genoemd; een vroeger gebruikt acroniem is OIS (Engels: Oxygen Isotope Stage). (nl)
  • Ett syreisotopstadium är ett klimatstadium i jordens historia som identifierats genom mätning av förhållandet mellan syreisotoper. Förhållandet mellan halterna av syreisotoperna 18O och 16O i havslevande skaldjur beror på jordens klimat. Genom mätningar av kvartära och neogena lagerserier på havsbottnarna har man identifierat över hundra syreisotopstadier som numreras från nutid och bakåt. Man använder den engelska beteckningen Marine isotope stage med förkortningen MIS. Som exempel motsvaras MIS 1 av vår nuvarande värmetid Flandern och MIS 10 av istiden Elster för 340-380 miljoner år sedan. Udda nummer utgör varma stadier och jämna nummer kalla stadier. (sv)
  • 海洋同位素阶段(Marine isotope stages),简称MIS,又称海洋氧同位素阶段、深海氧同位素阶段(Marine oxygen-isotope stages)或氧同位素阶段(Oxygen isotope stages)简称OIS, 用来描述地球冷暖交替周期。地球冷暖会影响海洋水中的δ18O数值的变化,暖的时候小,冷的时候大。阶段由今到古按冷暖依次编号,暖为奇数,冷为偶数,末次冰期结束后到现在为MIS1阶段,MIS2-4为末次冰期,MIS5则是。 (zh)
  • Kyslíkové izotopové stádium nebo kyslíkový izotopový stupeň (jiný, spíše novější, název: mořské izotopové stádium, mořský izotopový stupeň; angl. oxygen isotope stage, marine isotope stage; skr. OIS resp. MIS) je jedno z období, která za sebou následují od současnosti až do daleké minulosti, a které jsou definovány na základě změny v organických a anorganických nálezech z daných období. Tato změna má kvazi-cyklický charakter - v chladném období, kdy se zvětšují kontinentální ledovce, poměr stoupá, v teplém období, kdy se kontinentální ledovce zmenšují, poměr klesá. OIS se používá: (cs)
  • Sauerstoff-Isotopenstufe (auch: Marine Isotope Stage, MIS; Isotopenstadium oder engl. Oxygen Isotope Stage, OIS) bezeichnet in der Geologie die Datierung von Sedimentschichten anhand der in ihnen enthaltenen stabilen Isotope des Sauerstoffs. (de)

  • Os estágios de isótopos de oxigênio marinhos, estágios de isótopos marinhos (MIS) ou estágios de isótopos de oxigênio (OIS), alternam períodos quentes e frios no paleoclima da Terra, deduzidos de dados de isótopos de oxigênio que refletem mudanças na temperatura derivadas de dados de amostras do núcleo do fundo do mar. Trabalhando para trás a partir do presente, que é MIS 1 na escala, estágios com números pares têm altos níveis de oxigênio-18 e representam períodos glaciais frios, enquanto os estágios de número ímpar são vales nas figuras de oxigênio-18, representando intervalos interglaciais quentes . Os dados são derivados de restos de pólen e foraminíferos (plâncton) em núcleos de sedimentos marinhos perfurados, sapropels e outros dados que refletem o clima histórico; estes são chamados (pt)
