“…The system is composed by a depressor towed by a surface unit at fixed depth and an instrumented vehicle, that slides along a cable from the surface to the depressor. This approach starts from a previous development that was built in the mid-80s (Nomoto et al 1986). …”

“…A third approach to the oceanographic studies is the utilization of towed measuring devices [5], which permits a high sampling rate and a high spatial resolution, maintaining a quasisynoptic temporal view [6][7][8]. Although it has not been commonly used to date, it seems to be the best way to study several marine areas [9,10].…”

A modern approach to the study of pelagic ecosystems requires both an appropriate spatial and temporal resolution and a synoptic observation. For this reason, it is indispensable a rapid and high-resolution data acquisition along the water column. During the CNR project PRISMA II, four oceanographic cruises were performed in the Northern Adriatic Sea to analyse the high variability of ecological processes related to the frontal system. The SARAGO, a towed undulating vehicle, allowed a fine description of physical and biological acquired parameters (CTD, chlorophyll a concentration, photosynthetic efficiency, PAR). In succession, CTD and bottle carousel casts were performed to analyse physical and biogeochemical features. In this work, we compare the distribution and quantification of the relevant variables acquired by the two different sampling methods.A mathematical model was applied to estimate primary production.

SJAMSTEC has developed a data compression and data transfer system between a observation vessel and a ground station via a satellite communication system. At the ground station, images of sea surface temperature and surface albedo are extracted from surface data obtained from observation satellites, and are proceeded to compress its volume to reduce communication cost. On the vessel, data obtained from oceanographic instruments are processed to extract an information to present phenomenon of ocean and are proceeded to compress its volume. With a connection between the computer on the ground station and the computer on the vessel via the Inmarsat satellite communication system, data are transferred to each side. Data transferred from the ground station to the vessel help scientists to understand ocean where they are located. Data transferred from the vessel to the ground station help scientists to understand vertical structures of ocean without touching to ocean and without waiting the vessel.
