Modernisation of Hydrological Measurement Stations Along the River Elbe, Germany
End of last year AADI’s (Norway) German distributor Nautilus Marine Service GmbH was awarded a contract by the German Waterway and Shipping Administration (WSV) to modernise their network of hydrological monitoring stations along the river Elbe. The upgrade comprises 7 AADI Data Buoys and 10 river pile stations as well as the delivery of up to 130 SEAGUARD®
. The data buoys are fitted with a SEAGUARD® cable. Data from both SEAGUARD®
to monitor water flow (speed, direction), temperature, salinity, turbidity and oxygen. A second, identical configured SEAGUARD® is installed at approx. one meter above the river bed in a bottom frame and linked with the data buoy by a special data and lifting
s are stored and can be transmitted in real-time from the buoy into the network of the WSV.
The setup for the pile based stations is similar. Here the same parameters as for the buoys will be measured approximately 2 meters and 4 meters above the river bed and send out in real-time as well.
In addition to the acquisition of hydrological standard parameters along the river Elbe to fulfil their duties in terms of administration and the provision of safety for the federal waterway Elbe and adjacent territorial waters, the scientific focus has put back on the basic transport processes of sediments, suspended material and the morphological behaviour of the bottom zone of the tidal river Elbe and their natural and anthropogenic influences.

Observed rising dredging amounts at the Elbe estuary over the last years due to greatly increased dredging activities of the Hamburg Port Authority and an upstream shift of dredging areas of the WSV towards Hamburg during the same time period require more dredging capacities and subsequently more ecological tests have to be carried out to give real-time input to live data models predicting the transport of sediments into the shipping channels.

Aquaread Ltd (UK), the award winning British manufacturer of environmental water analysis equipment, has just launched the ODO Plus™, claimed to be the world’s most advanced portable Optical Dissolved Oxygen measurement system for field use.
Optical DO sensing technology allows high precision, membrane-free, long-term stability along with infrequent calibration and immunity to fouling by sulphide and other gases.
The new ODO Plus™ is the only portable Optical DO system currently available which includes direct EC measurement for accurate salinity compensation. Automatic temperature and barometric pressure compensation is also included.
Added to this, a built in GPS receiver tags all data measurements with precise geographic co-
ordinates so that up to 2000 sets of readings can be downloaded onto a PC and viewed against Google™ Maps or Google™ Earth satellite photographs.

Deep Water Sampling Representative Samples from Lake, River and Sea Water

One of the most simple and useful devices for water sampling is the "Mare-Lacus" sampling kit. It is a handy, light, stainless steel AISI 316 and PTFE Teflon sampler with an autoclavable glass container and a rope coil. It gives the possibilty to collect water samples at a pre- determined depth in sterile or non-sterile conditions (maximum depth 15 metres) from lake, river, sea, canal or tank. "Mare-Lacus" produced by International PBI (Italy) can be used from a boat or bridge. The opening and closures of the bottle cap at pre-detemined depth is commanded by a magnetic system.

The C3 Submersible Fluorometer from Turner Designs (USA) is now available with an Analog Output Adapter which outputs a 0-5 VDC signal for 1, 2, or 3 channels depending on the C3 configuration. The adapter enables integration with CTDs or any dataloggers that accept a 0-5 VDC signal. It plugs directly into the C3 and is securely held in place by the battery bracket. The C-Soft Windows-based user interface allows for intuitive C3 calibration, data logging, and data management.
The C3 Submersible Fluorometer incorporates up to three optical sensors, temperature, and depth. Sensors can be selected to detect in vivo Chlorophyll, blue green algae, rhodamine WT dye, fluorescein dye, crude oil, CDOM, optical brighteners for wastewater treatment, and turbidity. The C3 can
be used in freshwater, coastal and open ocean applications. The versatility of the C3 allows for both vertical profiling and long-term moored data collection. The C3 can also be used for continuous flow sampling with the addition of the flow cap.
