E2-M3A

Southern Adriatic Interdisciplinary Laboratory for Ocean Research

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.

March 2017
Deployment FixO3-RITMARE07. The maintenance campaign is carried out using two naval vessels: MN Pasquale Cristina and NR Minerva UNO. During these two campaigns, the following operations are done: recovery of the buoy (including rope lined and acoustic releasers) and of the deep mooring, ground instrument maintenance and sea retrieval. Due to safety reasons and permissions, the NR Minerva UNO was used for the deployment of the heavy ballast (2Tons) of the buoy.

All instruments, belonging to both surface buoy and deep mooring, have been cleaned, washed and maintained. Specifically, the quality of the recorded data (through pre-processing of the acquired data), battery life and residual battery charge at data discharging were verified. All the CTDs were supplied with new batteries and were re-programmed to start recording from 26-03-2017 00:00:00. Finally, they were deployed with MN Pasquale Cristina on March 25th, 2017.
November 2016The E2M3A observatory is successfully maintained and the TNA experiment continues 
April 2015The 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.

Distance from Land 100 km
Max Depth 1220 m
Oceanographic features of area The Southern Adriatic is an area of dense water formation through open-sea convection.

The dense water formed locally is named Adriatic Dense Water (AdDW). During winter, vertical mixing (upwelling, wintertime convection) has a rather prominent role in homogenizing physical and chemical seawater properties down to 800m depth, and in controlling the primary production (upwelling water is a source of nutrients in the euphotic zone, which stimulates the growth of phytoplankton).
Additionally, also very dense water formed during favourable winter conditions on the Northern Adriatic Shelf (NAdDW) reaches the Southern Adriatic 2-3 months after its formation. Once arrived following the Western Adriatic current along the Italian coast and dendending on its density, it is able to sink to the very deep layer of the Southern Adriatic Pit.

Both AdDW and NAdDW flow through the Strait of Otranto to the abyssal Eastern Mediterranean basin and become the main component of the Eastern Mediterranean Deep Water (EMDW), sustaining the thermohaline circulation of the whole basin.

TNA

The observatory has been working continuously since 2006, providing valuable information on the interannual variability of the processes of formation of water masses. In the context of Eurosites (EU-FP7_European Network of Observatories) (http://www.eurosites.info/), in summer 2009 it was stationed a completely redesigned system for the surface buoy, which is now part of the European contribution OceanSITES the global array (www.oceansites.org). The E2M3A system is characterized by a surface buoy and a subsurface single mooring line. The surface buoy hull of welded steel construction has a discus shape (diameter 2 m), which provides three main compartments, provision for installation of sensors, ballast compartments and provision for the attachment of the superstructure. Inside there is a Control Panel that manages the acquisition and system electronics (power management, solar panels, GPS, battery voltage and current, internal temperature, orientation, etc.). The position of the buoy is controlled with GPS and monitored by Argos beacon (ARGOS 1-way comm) that transmit the position if the anchor line is accidentally severed. A Globalstar satellite link in turn enables the real-time transmission from the platform to the ground station. The secondary mooring line houses a chain of instruments with sensors at different depths to measure physical and chemical charachteristics from intermediate layer to the bottom. An Iridium SBD beacon is installed to transmit the position during the recovery operations and in case of breakage of the mooring rope. Each anchor line is equipped with double releasers to allow easy retrieval of the system. The three types of measurements that are collected at the E2M3A are: • Air-sea interface measurements which includes a meteorological station and solar radiation sensor; • Biochemical (pH and pCO2) and physical properties of the subsurface layer (10m depth) through probes attached on a metal cage and transmitted to the surface buoy through an inductive cable; • Biochemical (Dissolved Oxygen) and physical properties (Temperature, Conductivity, horizontal and vertical Currents, Transmissometer) of the seawater in the layer 100m-bottom through probes attached on a deep mooring line. The data are subject to a quality control according to the OceanSITES procedures. The delayed mode data are typically controlled within 2-6 months after the recovery of the equipment, provided in NetCDF OceanSITES format and stored at the National Oceanographic Data Centre (NODC-OGS) of Trieste.

Potential Additional Uses
Data Ports Surface buoy : the Electronic Control Panel can accommodate up to 6 communication ports. Currently there are no available ports. It is however always possible to accommodate self-powered and self-recording instruments both in air (on the superstructure) than in water (on the cage).

Subsurface mooring : compatibly with the installation limits is possible to host several self-powered and self-recording instruments.

Availability of External Power Surface buoy: a power connection only (12v) is available in the Electronic Control Panel to install instruments on the superstructure. Also available is an unused cable in the umbilical that can carry power (12v) for a subsurface instrument (on the cage).
Instrument installation methodology

Schematic drawings of the surface and subsurface moorings show the installation details. Deep observatory_e2m3a_march15 Buoy_e2m3a_march15 User groups have to provide mechanical and electrical specifications of the instruments to assess consumption, type of connectors, brackets, clamps, etc.

Data History

Details on the data/istruments history are summarized in the following document: e2m3a_DataHistory_OGSSite_05062015

Instrument installation methodology The two anchor lines that constitute the observing site follow two separate maintenance procedures.
The subsurface mooring consists of self-powered and self-contained instrumentation and therefore has a fixed time limit related to power and memory capacity. In addition, the architecture of the mooring require adequate vessels, weather and sea conditions for maintenance.
Procedure: Recovery of the mooring line - Download of the recorded data - Routine maintenance of the instruments (eventual replacement in case of damage) - Redeployment of the mooring line at the same location.
The surface buoy has a greater accessibility and therefore require less use of resources for ordinary maintenance, that consists of superstructure sensors and power system inspection. At scheduled intervals is operated the recovery of the instruments in the cage at 10 m depth. The power supply system with solar panels allows scheduling intervals less close than the deep mooring.
Observatory maintenance estimated or planned schedules The observatory maintenance is scheduled in a range of 8-12 months for the subsurface mooring and 1 year for the surface buoy.
