摘要

有孔虫组合是环境变化的强有力的生物指标,并在位于佛罗里达群岛西南地区的马克萨斯群岛收集的沉积物岩心中进行了分析。14C和210Pb测年的沉积物岩心顶部85 cm有孔虫组成和丰度测试揭示了1990年、1939年和1872年有孔虫组合的变化。基于优势种的生态偏好,盐度和水下植被(SAV)覆盖的变化可能影响有孔虫的物种组成。这些变化可能是由墨西哥湾东部地区降水模式的变化引起的,这些变化与主要海洋-大气遥相关的变化有关,如厄尔Niño南方涛动(ENSO)、大西洋多年代际涛动(AMO)、北大西洋涛动(NAO)以及热带风暴和飓风。这些气候现象的长期负相位与有孔虫组合的变化相吻合。尽管海洋-大气遥相关对南佛罗里达地区产生了普遍的负面影响,但在研究的岩心中记录了发育良好的附生植物组合。该组合记录在岩心的最上部,时间为公元1990年至2010年。这意味着一个密集的SAV社区存在于马克萨斯群岛穆尼港至少从20世纪90年代初。

Reconstruction of climate-induced environmental changes in the eastern Gulf of Mexico based on foraminifera sediment assemblages

Foraminifera assemblages are powerful bioindicators of environmental change and were analyzed in a sediment core collected from the Marquesas Keys, located in the southwestern region of the Florida Keys. The composition and abundance of foraminifera tests within the top 85 cm of the sediment core, dated with 14C and 210Pb, revealed changes in foraminifera assemblages in 1990 CE, 1939 CE, and 1872 CE. Based on the ecological preferences of the dominant species, changes in salinity and submerged aquatic vegetation (SAV) cover may have influenced foraminifera species composition. These changes were likely caused by variation in precipitation patterns in the eastern Gulf of Mexico region associated with shifts in the major ocean-atmosphere teleconnections such as the El Niño Southern Oscillation (ENSO), Atlantic Multidecadal Oscillation (AMO), North Atlantic Oscillation (NAO) along with tropical storms and hurricanes. Prolonged periods of the negative phases of these climate phenomena coincided with shifts in foraminifera assemblages. Despite a generally negative impact of the ocean-atmosphere teleconnections on the South Florida region, a well-developed epiphytic assemblage was recorded in the studied core. The assemblage was recorded in the uppermost part of the core and dated to the period between 1990 and 2010 CE. This implies that a dense SAV community was present within the Marquesas Keys Mooney Harbor since at least the early 1990.

期刊介绍: The Journal of Sea Research is an international and multidisciplinary periodical on marine research, with an emphasis on the functioning of marine ecosystems in coastal and shelf seas, including intertidal, estuarine and brackish environments. As several subdisciplines add to this aim, manuscripts are welcome from the fields of marine biology, marine chemistry, marine sedimentology and physical oceanography, provided they add to the understanding of ecosystem processes.
