The new pelagic Operational Observatory of the Catalan Sea (OOCS) for the
coordinated multisensor measurement of atmospheric and oceanographic conditions has
been recently installed (2009) in the Catalan Sea (41°39'N, 2°54'E; Western Mediterranean)
and continuously operated (with minor maintenance gaps) until today. This multiparametric
platform is moored at 192 m depth, 9.3 km off Blanes harbour (Girona, Spain). It is
composed of a buoy holding atmospheric sensors and a set of oceanographic sensors
measuring the water conditions over the upper 100 m depth. The station is located close to the head of the Blanes submarine canyon where an important multispecies pelagic and
demersal fishery gives the station ecological and economic relevance. The OOCS provides
important records on atmospheric and oceanographic conditions, the latter through the
measurement of hydrological and biogeochemical parameters, at depths with a time
resolution never attained before for this area of the Mediterranean. Twenty four moored
sensors and probes operating in a coordinated fashion provide important data on Essential
Ocean Variables (EOVs; UNESCO) such as temperature, salinity, pressure, dissolved
oxygen, chlorophyll fluorescence, and turbidity. In comparison with other pelagic
observatories presently operating in other world areas, OOCS also measures photosynthetic
available radiation (PAR) from above the sea surface and at different depths in the upper
50 m. Data are recorded each 30 min and transmitted in real-time to a ground station
via GPRS. This time series is published and automatically updated at the frequency of
data collection on the official OOCS website (http://www.ceab.csic.es/~oceans). Under
development are embedded automated routines for the in situ data treatment and
assimilation into numerical models, in order to provide a reliable local marine processing
forecast. In this work, our goal is to detail the OOCS multisensor architecture in relation
to the coordinated capability for the remote, continuous and prolonged monitoring of
atmospheric and oceanographic conditions, including data communication and storage.
Accordingly, time series of measurements for a number of biological parameters will be
presented for the summer months of 2011. Marine hindcast outputs from the numerical
models implemented for simulating the conditions over the study area are shown. The
strong changes of atmospheric conditions recorded in the last years over the area have
altered the marine conditions of living organisms, but the dimension of the impact remains
unclear. The OOCS multisensor coordinated monitoring has been specifically designed to
address this issue, thus contributing to better understand the present environmental
fluctuations and to provide a sound basis for a more accurate marine forecast system.
