Observatories

ANTARES

Multidisciplinary, permanent marine observatory providing high-bandwidth real-time data transmission from deep-sea for geosciences and marine environmental sciences. Site is part of the MOOSE network providing real-time data transmission through two deep cabled moorings. These moorings are complemented by stand-alone mooring near the junction box. Physical and biogeochemical parameters recorded by autonomous sensors with regular maintenance. In addition monthly ship occupation for CTD profiles and seawater collection. Cabled extension of the neutrino telescope is offering connectors for direct link to shore in addition to operational seismometer already in place.

Biscay AGL

Mooring in SE Bay of Biscay it comprises a fully-equipped ODAS buoy transmitting data in real-time plus monthly hydrographical and biogeochemical sampling of water column from research vessel. Buoy obtains core measurements of meteorological, physical, biogeochemical, and ecological parameters with high significance to weather forecasting and climate monitoring. Data immediately provided through IEO web page (hourly).

CIS

Multidisciplinary mooring, located in the Central Irminger Sea, Subpolar North Atlantic and part of the FP7 NACLIM project.
The site is located in the centre of the Irminger Gyre, characterized by particular deep winter mixed layer depth. The mixed layer deepening is promoted through the combination of the cyclonic circulation of the Irminger gyre and strong surface buoyancy forcing in winter.
Focus of the interdisciplinary research is on the biogeochemical cycling in a potential deep water formtion area. The physical background field (Temperature, Salinity, Currents) of the upper 1500m is surveyed with a number of sensors. Moreover, biogeochemical sensors (O2, Chl-a, zooplankton) is measured in mixed layer.

The site area is shared with the LOCO mooring established by the NIOZ in 2002. The sampling and logistics of the moorings is coordinated with the NACLIM project.

In Septmber 2014 the CIS observatory was moved little south and the original position is now occupied by the 4 mooring construction as part of the US OOI initiative. With this configuration one observatory (OOI) is located at the center of the gyre, while CIS and LOCO are where typically the strongest buoyancy focring is found (related to the Greenland Tip Jet).

 

CVOO

This observatory is composed of a mooring and a small vessel maintaining the time-series continuity at Tropical Eastern North Atlantic.

DELOS A

The DELOS (Deep-ocean Environmental Long-term Observatory System) system comprises two environmental monitoring platforms: DELOS A located in the near field (within 50 m of a sea floor well); and DELOS B located in the far field (~16 km from sea floor infrastructure).

DELOS A located on flat (<1° slope), finely sedimented sea floor within petroleum lease Block 18 in a mid- slope area off Angola between the deep-sea fans of the Congo and Kwanza rivers.  The platform hosts a camera module, oceanographic module and acoustic module, each with multiple instruments.

DELOS B

The DELOS (Deep-ocean Environmental Long-term Observatory System) system comprises two environmental monitoring platforms: DELOS A located in the near field (within 50 m of a sea floor well); and DELOS B located in the far field (~16 km from sea floor infrastructure).

DELOS B located on flat (<1° slope), finely sedimented sea floor within petroleum lease Block 18 in a mid- slope area off Angola, between the deep-sea fans of the Congo and Kwanza rivers.  The platform hosts a camera module, oceanographic module and acoustic module, each with multiple instruments, plus a sediment trap module.

DYFAMED

Multidisciplinary site within MOOSE network (Ligurian Sea), in passage between eastern and western Med Sea. Strong influence of atmospheric deposition influencing productivity and particle export monitored by atmospheric survey (Cap Ferrat) and two permanent sediment traps. Physical parameters recorded from surface to deep waters through monthly visits and permanent deep mooring. Biogeochemical parameters obtained monthly during ship visits. The site is also a way point of gliders and used for cross- validation of bio-parameters (nitrate, oxygen).

E1-M3A

Multidisciplinary mooring located at the eastern Mediterranean off shore Crete island, an area of open sea conditions, characterized as extremely oligotrophic where dense waters with intermediate and deep characteristics are formed.

E2-M3A

Deep-sea, continuous monitoring station: it provides the longest oceanographic time series in the South Adriatic Pit (Eastern Mediterranean Sea). The observatory is composed by two moorings (surface buoy and sub-surface mooring line) and designed to monitor physical and biogeochemical processes in the water column from the surface down to the bottom (approximately 1220m).  The E2-M3A surface buoy collects air/sea meteorological and physical measurements in the surface layer (2m depth). The secondary deep mooring instead, is equipped with current meters (RDI-ADCP and Seaguard-RCM), CTD’s with Dissolved Oxygen and optical sensors. New biochemical sensors (CO2 and pH) were deployed during the first year of the FiXO3 project to enhance the payload of the site.

April 2015 The E2M3A observatory participates to the first TNA (Trans National Access) call, receiving the proposal of Aanderaa: “COMbined testing of new acoustic profilers with Biochemical Optodes in the Adriatic Sea [COMBO] “. See all news on  http://nettuno.ogs.trieste.it/e2-m3a/news.html

Nov 2015

The FixO3-RITMARE05 maintenance cruise was carried out in the southern Adriactic Sea in the framework of the COMBO TNA proposal : “COMbined testing of new acoustic profilers with Biochemical Optodes in the Adriatic Sea [COMBO] “. The FIXO3- RITMARE05 cruise has been held successfully on board the R/V OGS-Explora from the 26 October to 4 November 2015. The principal aim of the oceanographic campaign was the complete maintenance of the multi-parameter moorings constituting the SAILOR-E2M3A Site and the monitoring of the properties of the western area of the southern Adriatic by means of the repeated Bari Dubrovnik transect (only in Italian waters).
The high sea temperatures recorded during this summer resulted in extremely high biofouling that covered most of the instruments positioned in the buoy tube and surface cage. Following the best practices procedures already in act, on this occasion inter-calibration tests have been conducted to compare and verify measurements made by CTD’s installed on the moorings with those made with the CTD 9/11 probe. The latter normally used as control probe. Two tests were conducted: the first immediately after the recovery of the mooring, instruments using the same batteries and the second before the redeployment with new batteries and cleaned instruments. In both case the sampling time was set to 5’.
For both tests the mooring self-recording instruments were mounted on the SBE32 Carousel sampling device together with the CTD 9/11 probe and lowered at 300 m for 1 hour in the first case and at 1000m for 45minutes. Water samples for dissolved oxygen and salinity calibration were also taken. The results will give valuable information on the accuracy of the recorded time series. Finally, a drifter of the EuroARGO program was released in the area of the southern Adriatic Pit.
