Turbidity (NTU) data from the LTER-Eastern Ligurian Sea Site (Italy), 2020-2021

since 2015, enea as coordinator of the eastern ligurian sea site in the long term ecological research network (lter) has collected turbidity data at different depths (centroid/representative coordinates latitude: 44.002684 longitude: 9.992889; https://deims.org/56a6b13f-7c03-4bfa-ad4f-5f7e0f8189ca). turbidity is measured in nephelometric turbidity unit (ntu), referenced to a proper turbidity standard. turbidity measurements are performed by using a nephelometric turbidimeter connected to a ctd probe (mod. sbe19plus). for each profile, the ctd is deployed at well-known depths together with the go-flo bottle (for total suspended solids samples) by using the winch of the research vessel. turbidity measures are acquired at a sampling rate of 4 hz and stored in the internal buffer of the ctd, ready to be downloaded for post-processing. turbidity values range up to about 80 ntu, but the main part of measures is below 20 ntu. the lter eastern ligurian sea site has as its main purpose the study of coastal ecosystems (especially coralligenous communities and long-lived benthic species in the area), hydrodynamic processes and, in the long term, the effects of climate change. the dataset proposed here refers to the years 2020 and 2021, and will be upgraded periodically.

自2015年起，作为长期生态研究网络（LTER）中东部利古里亚海站点的协调者，enea长期收集不同深度的浊度数据（中心/代表性坐标纬度：44.002684，经度：9.992889；https://deims.org/56a6b13f-7c03-4bfa-ad4f-5f7e0f8189ca）。浊度以 nephelometric turbidity unit（NTU）为单位进行测量，并参照适当的浊度标准。浊度测量通过连接至CTD探头（型号：sbe19plus）的 nephelometric turbidimeter进行。对于每个剖面，CTD探头在已知深度处与go-flo瓶（用于总悬浮固体样品）一同部署，利用研究船的绞车完成。浊度测量以4Hz的采样率进行，并存储在CTD的内部缓冲区中，以便后续下载处理。浊度值范围约为80NTU，但主要测量值低于20NTU。LTER东部利古里亚海站的主要目的是研究沿海生态系统（尤其是该地区的珊瑚礁群落和长寿底栖物种），水文过程，以及长期气候变化的影响。此处提出的数据集涉及2020年和2021年，并将定期更新。
