Abstract Globorotalia truncatulinoides oscillations have been recorded from different marine sediment cores collected in the central and western Mediterranean Sea. The abundances of this species over the last 500 yrs. demonstrates its potential value as bio-indicator of particular oceanographic condition during the Maunder Minimum (MM) event of the Little Ice Age (LIA). The comparison between the G. truncatulinoides abundance patterns of the Balearic Basin, central and south Tyrrhenian Sea and central and eastern Sicily Channel allows to highlight a similar response of this species during the MM event in the central-western Mediterranean Sea. The ecological meanings of this species and its peculiar high abundance percentages in the total assemblages suggest the development of enhanced vertical mixing conditions during MM winter season with a strong advection of nutrients from the nutrient-rich deeper layers and enhances the productivity levels in the mixed layer. The intensified vertical mixing could be linked to persistence of an atmospheric blocking event recorded by several authors during the MM.

小冰河时代中西地中海的Globorotalia truncatulinoides

摘要 Globorotalia truncatulinoides 振荡已从地中海中部和西部收集的不同海洋沉积物芯中记录下来。该物种在过去 500 年的丰度。证明了其作为小冰河时代 (LIA) 的蒙德极小期 (MM) 事件期间特定海洋条件的生物指标的潜在价值。巴利阿里盆地、第勒尼安海中部和南部以及西西里海峡中部和东部的 G. truncatulinoides 丰度模式之间的比较可以突出显示该物种在地中海中西部的 MM 事件期间的类似反应。该物种的生态意义及其在总组合中独特的高丰度百分比表明，在 MM 冬季期间发展了增强的垂直混合条件，营养物质从富含营养的深层进行强烈平流，并提高了混合层的生产力水平. 加剧的垂直混合可能与多位作者在 MM 期间记录的大气阻塞事件的持续存在有关。
