Bari ;Cipriani, S.; Provincia La Spezia ;De Marte, M.; Istituto Idrografico Marina Militare; ; ; ; ;; ; ; This paper highlights some magnetic evidences revealed by a recent marine magnetic survey ran near the Margherita di Savoia shoreline, Puglia (Italy). The survey has been planned to probe one of the expected settlement site not perused yet. The accurate elaboration of high density total magnetic field intensity data shows some features which can be interpreted as markers of harbor framework, at present time partially uprooted. A model of the bodies which cause the magnetic anomaly is also provided.183 460 - PublicationOpen AccessEnvironmental magneto-gradiometric marine survey in a highly anthropic noisy area(2009-10)

This region, which is a noisy harbour environment, provides a challenging test for magnetic methods. To reduce spurious noise signals, with both temporal and spatial origins, we used two Geometrics G880 model caesium magnetometers towed in a transverse gradient configuration. We show how, in shallow waters, this gradiometric configuration allows us to distinguish anomalies due to small metallic bodies near the seabed from the induced noise due to the anthropic contribution and geomagnetic field variations. A direct visual inspection confirmed that the peculiarities highlighted in the gradient anomaly map were due to abandoned metallic objects found on the seabed.555 191 - PublicationOpen AccessSurface circulation in the Liguro-Provençal basin as measured by satellite-tracked drifters (2007-2009)(2010-01)

Complex circulation patterns prevailed in the eastern Ligurian Sea, before the drifters eventually joined the Northern Current (NC) in the coastal area off Genoa. Between 5°E and 7°E30’, most drifters were advected offshore before heading to the east and eventually closing a basin-wide cyclonic circulation. This offshore turning is related to the wind and wind stress curl during Mistral events. Although the Western Corsican Current was well delineated by the drifters, no signature of the Eastern Corsican Current was shown, indicating limited connectivity between the Tyrrhenian and Ligurian seas in summer 2007. Pseudo-Eulerian velocity statistics were calculated in the coastal region extending between Genoa and the Gulf of Lyons. Fast currents are evident on the shelf break, especially off Imperia (maximum of 90 cm/s) where the bathymetric slope is larger and the NC is closer to shore and narrower. In contrast, a stagnation area inshore of the NC near Fréjus is characterized by little mean flow and low velocity fluctuations. Mean currents are also reduced off Menton-Nice where the variability is maximum. More to the west, the NC broadens and slightly reduces in strength.404 600
