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)

Thales Completes Thames Measurement Programme

Thales Geosolutions environmental and metocean services division has recently successfully completed a thirteen-month long oceanographic measurement programme in the outer Thames estuary. The programme was conducted for Hydrosearch and is part of a pre-development study for the erection of an offshore wind farm. Using its dedicated data processing facilities based at its offices in Cape Town, Thales delivered a comprehensive range of product services to complement the measurement programme. In addition to using manufacturer-supplied software, Thales has developed Matlab-based data processing software to conduct rigorous quality control on data and present it in whatever format is required by the client....

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)

Versatile Tide Gauge

Valeport Ltd, UK, has introduced a seabed-mounted tide recorder that makes precise water level measurements where conventional units attached to piers and jetties are not practicable. Applications are in oceanography, hydrography and marine civil engineering projects. Called the MIDAS Tide Recorder, the new instrument is also designed to be part of an in-line mooring. The high accuracy (±0.01 per cent) pressure sensor and temperature sensor is housed in acetal rated to 1,000m water depth. The MIDAS Tide Recorder has a wide range of sampling regimes and rates. It can sample at 1, 2, 4 or 8Hz and can log/output data... (read more)

NOAA Uses RS to Monitor Algae

Using remote sensing technology, scientists at NOAA have developed a way in which to identify and monitor harmful algal blooms. This monitoring will help detect HABs along the coastal areas of the US, where they are causing concern, while providing more information to managers on how to reduce the impact of these toxic blooms. Scientists from the NOAA National Centers for Coastal Ocean Science are monitoring HABs using a combination of ocean colour satellite imagery with field and meteorological data. Satellites from the Sea-viewing Wide Field of view Sensor (SeaWiFS) owned by Orbimage provide information on the colour of the... (read more)
