MABEL 1 - Transmissometer Marinaro, Giuditta. (2005). Transmissometer dataset (Ctg Alphatracka II @ 1 sample / hour) from INGV/SN-2 seafloor platform during MABEL project in Weddell Sea site (Weddell Sea), part of PNRA network. dataset Alphatracka MKII is a transmissometer monitors the total suspended matter in water by measuring the beam attenuation coefficient alfa at 660 nm. Transmissometer provides information about possible suspension of particle matter due to bottom currents. The time-series is complete and continue through all period of measurement, without gap of data or relevant sensor problem. info@moist.it Istituto Nazionale di Geofisica e Vulcanologia (INGV) en UTF-8 UTF-8 open false Multidisciplinary Oceanic Information SysTem (MOIST)
