Registering Climatic Variability

To increase our understanding of climatic variability it is vital to be able to measure changes in nature. One way of doing this is by measuring sea temperature, current speed and direction over time. Aanderaa Instruments in Norway has just delivered thirty Recording Current Meter RCM 11s (a Doppler Current Meter) for long-term ocean observation experiments. The aim is to study the world’s ocean circulation and climatic variability. The instruments will be placed in four key areas of ocean circulation in the world: The Canary Basin The Irminger Sea, Labrador Sea The Mozambique Channel East Indonesia During the next five...

Emu Survey for Thames Dredging

Emu Ltd, UK, has completed a study in the Thames Estuary to provide comparative data for a dredging programme. The Port of London Authority commissioned Emu to monitor background dissolved oxygen (DO2) and suspended sediment levels in support of a maintenance dredging project in the Princes Channel on the southern side of the Estuary. The Emu-gathered data will be compared with data gathered during dredging to determine the effect of dredging activity on the marine environment. The data was obtained from a custom-designed seabed-mounted frame with sensors positioned one metre above the seabed. (read more)

More Instruments for China

China Ocean Technology Centre in Tianjin has for years used equipment from Aanderaa Instruments in Norway to measure temperature, current speed and current direction in the ocean. Now the centre has bought another thirteen units of the Doppler Current Meter RCM 9 and RCM 11. China Ocean Technology Centre is a research centre outside Beijing and has for a long time studied changes in the ocean. The Doppler Current Meter is well suited for deep-sea operations and has a depth capacity of 6,000 metres below sea level. The meters delivered to the Chinese Centre have sensors that measure sea temperature,... (read more)

LinkQuest Data Fusion Functions

LinkQuest high-speed underwater acoustic modems have recently incorporated data fusion functions. All LinkQuest modems can now interface to up to eight underwater sensors or devices using the RS232 interface. These systems can also sample up to sixteen analogue inputs simultaneously and provide up to 1Gbytes of permanent storage on a compact flash disk. Using this platform, LinkQuest Inc. delivered two sets of UWM2000 modem systems to Fugro Change Inc. Early 2003. These systems interface to a DigiQuartz depth sensor, a load cell and a compass and pitch/roll sensor. The sensor data is stored on a compact flash data logger at... (read more)
