Five of the units included pressure sensors to determine the changing water levels for the purposes of data collection, with the further use of the results for hydrodynamic modeling.These measuring stations each consist of a 2.5 m long stainless steel pole that is vertically anchored in the tidal flats. The pressure sensors are positioned approximately 20 cm above the seabed to determine the changing water levels. On the upper part of the pole, protected by stainless steel housing, are the secure and waterproof mounted Tide Master device

The corer is universally acknowledged as being the only way of reliably collecting a truly undisturbed sediment sample from the seabed.The multiple corer is hydrostatically damped to control the speed of descent of the core tubes into the sediment, and is constructed from stainless steel. The system features detachable core assemblies, which enables the core tubes (or if necessary the entire core tube assembly) to be removed from the corer for analysis or storage. The core tubes are sealed top and bottom once the sample has been taken, allowing rapid retrieval of the corer without

Ty-Met Cable Ties Help Maintain Position in High-vibration Applications

Ty-Met stainless steel retained-tension ball-lock cable ties, new from Thomas & Betts (T&B), a member of the ABB Group, feature specially formed spring crimps that help maintain consistent tension on the tie after installation. Consistent tension enables the cable tie to remain in position, even under high-vibration conditions. “Ty-Met retained-tension cable ties won’t slide down the bundle of cables after installation,” said Ralph Donati, product marketing director, Installation Products, at ABB Electrification Products. “The spring crimp was engineered to

molded PE hulls are foam filled to prevent the buoy sinking in the unlikely event that the outer hull is damaged. All instrumentation and cables are held internally and are protected by the rugged enclosed top section, which has been designed to minimize damage from the elements or interference. The stainless steel central structure removes the possibility of any corrosion issues, while offering good water flow for water quality sensors, while also providing a very high degree of protection for valuable, sensitive, or delicate equipment.    The platforms also offer a higher visibility profile
