Long-term time series of high frequency sampled sea level data collected in the Port of Genoa are analyzed to investigate the sub-daily variability. Spectral analysis evidences a well developed energy peak on 20–30 minutes band. Oscillations on this frequency band, the so-called meteo-tsunami, are an almost frequent feature in the analyzed signal. Their amplitudes are generally of few centimeters...
An upward-looking 150kHz narrow-band Acoustic Doppler Current profiler was operated in Terra Nova Bay (Ross Sea, Antarctica) from 5 February 2000 to 16 January 2001 to monitor marine currents. The instrument sampled the upper 160m of the water column with a time resolution of 1h. Although the experimental setup was not specifically designed to assess zooplankton and fish distributions and behaviour,...
A significant amount of Expendable Bathythermograph (XBT) data has been collected in the Mediterranean Sea since 1999 in the framework of operational oceanography activities. The management and storage of such a volume of data poses significant challenges and opportunities. The SeaDataNet project, a pan-European infrastructure for marine data diffusion, provides a convenient way to avoid dispersion...
Underwater acoustic measurements have been recently carried out in Tethys Bay (Ross Sea, Antarctica) during the XXIX Italian Antarctic Expedition to support acoustic propagation studies in the area and to investigate the environmental noise. Tethys Bay is a small deep cove close to the Antarctic Italian base Mario Zucchelli Station (Baia Terra Nova −74°42' S e 164°07' E) and covered with sea-ice for...
Three years of 300 kHz Acoustic Current Doppler Profiler ancillary data collected in the Central Ligurian Sea are analyzed to investigate the zooplankton diel vertical migration in the upper thermocline. After a pre-processing aimed at avoiding the slant range attenuation, hourly volume backscattering strength time series were obtained. Despite the lack of concurrent net samples collection, different...
Continuous marine environment monitoring is one of the main scientific topic for the oceanographic community involved in the analysis of climate changes and in the implementation of coupled ocean-atmosphere models. However, the space-time scale of the physical phenomena to be investigated, the need of resources and adverse meteo-marine conditions make difficult collecting long time series of in-situ...
