Variability in Shelf Sedimentation in Response to Fluvial Sediment Supply and Coastal Erosion over the Past 1,000 Years in Monterey Bay, CA, USA.

This dataset contains sedimentological and geochronological data from 5 sediment cores collected from Monterey Bay, CA, USA. The purpose of this data was to investigate changes in sedimentation on the Monterey Bay shelf over decadal and centennial time scales. All cores were collected from continental shelf areas, in water depths of ~100 m or less, and the cores were collected in 2014 and 2017. Four of the cores were collected using a multi-corer and were less than ~35 cm in length, the fifth core was collected using a gravity corer and was ~90 cm in length. The data include grain size data, 210Pb activities, 137Cs activities, and 14C dates.

本数据集包含采自美国加利福尼亚州蒙特雷湾的5根沉积岩芯（sediment cores）的沉积学与地质年代学数据。该数据旨在探究蒙特雷湾陆架（continental shelf）在十年至百年时间尺度上的沉积作用变化。所有岩芯均采自水深约100米及以下的大陆架区域，采样时间为2014年和2017年。其中4根岩芯通过多管取样器（multi-corer）采集，长度不足约35厘米；第5根岩芯通过重力取样器（gravity corer）采集，长度约90厘米。数据内容涵盖粒度数据、铅-210（²¹⁰Pb）活度、铯-137（¹³⁷Cs）活度及碳-14（¹⁴C）测年数据。
