Turbidity (NTU) data from the LTER-Eastern Ligurian Sea Site (Italy), 2015

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 year 2015 and will be upgraded periodically.

自2015年起，作为长期生态研究网络（LTER）东部利古里亚海站点的协调员，ENEA收集了不同深度的浑浊度数据（中心/代表性坐标：纬度44.002684，经度9.992889；https://deims.org/56a6b13f-7c03-4bfa-ad4f-5f7e0f8189ca）。浑浊度以 nephelometric turbidity unit（NTU）为单位进行测量，并参照适当的浑浊度标准。测量工作是通过将 nephelometric turbidimeter 连接到 ctd 探头（型号sbe19plus）来完成的。对于每个剖面，CTD在已知深度处部署，同时使用研究船的绞车将 go-flo 瓶（用于总悬浮固体样品）一同放下。浑浊度测量以4 Hz的采样率进行，并存储在CTD的内部缓冲区中，以便进行后续下载处理。浑浊度值范围大约在80 NTU左右，但大部分测量值低于20 NTU。LTER东部利古里亚海站的主要目的是研究海岸生态系统（尤其是该地区的造礁生物群落和长寿底栖物种），水文动力学过程，以及长期气候变化的影响。此处提出的dataset主要涉及2015年，并将定期更新。
