Turbidity (NTU) data from the LTER-Eastern Ligurian Sea Site (Italy), 2017

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 2017 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者，ENEA收集了不同深度的混浊度数据（中心/代表性坐标：纬度：44.002684，经度：9.992889；https://deims.org/56a6b13f-7c03-4bfa-ad4f-5f7e0f8189ca）。混浊度以 nephelometric turbidity unit（ nephelometric turbidity unit，NTU）为单位进行测量，并参照合适的混浊度标准。混浊度测量通过将 nephelometric turbidimeter 连接到 ctd 探头（型号：sbe19plus）进行。对于每个剖面，使用研究船的绞车将 ctd 在已知的深度部署，同时使用 go-flo 瓶（用于总悬浮固体样品）进行采集。混浊度测量以4Hz的采样率进行，并存储在 ctd 的内部缓冲区中，以便进行后期处理。混浊度值高达约80NTU，但大部分测量值低于20NTU。LTER东部利古里亚海站的主要目的是研究海岸生态系统（尤其是该地区的珊瑚礁生境和长寿底栖物种），水动力学过程，以及长期而言，气候变化的影响。此处提出的数据集涉及2017年，并将定期更新。
