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 2022 and 2023, and will be upgraded periodically.
