Measurement of water quality in coastal regions and estuaries is critical in the characterization of hypoxic ‘dead zones’ as a result of nutrient loading and algal blooms in the water bodies. Sediment loading analysis through turbidity measurement is also important for coastal trend identification and modeling. Hydrolab and Sea-bird Coastal offer a variety of multiparameter water quality instrumentation and nutrient sensors for long-term coastal applications.
Sea cargo containers and wooden packing materials are fumigated to control the spreading of pest animals and micro-organisms. Fumigant gases are toxic and measurements are carried out as a health and safety precaution. Measurements are required by e.g. customs inspectors prior to opening containers, making the shipping companies responsible for carrying out measurements. Products shipped in containers may release VOCs from e.g. solvents and glues used in manufacturing process. The concentrations of vapors may be...
Researchers at Battelle Pacific Northwest Laboratory used a Tekran 2600 on a 2009 ship cruise. Due to the low levels of mercury in water, Tekran provided them with a custom 2600 Event Table to pre-concentrate mercury from multiple samples to push the detection limit lower. When planning an ocean bound cruise, instrument dependability is a paramount concern. At sea, there is no possibility to return instrumentation to the manufacturer for quick repair. The Tekran 2600 has a well deserved reputation for dependability...
OPSIS provides various monitoring solutions for marine vessels. One application is to monitor in Inert Gas Generators (IGG) onboard ships to control the quality of the nitrogen. The reliable systems supply accurate values continuously, and presents it directly to the control system.
Machine condition monitoring based on oil analysis has become an important, if not mandatory, maintenance practice by the marine industry. An effective oil analysis program will keep important assets such as engines, gearboxes, hydraulic systems, turbines, compressors, generators and any other oil-wetted machinery in operation by reducing unexpected failures and costly unscheduled down time.
Climate change makes for more extreme weather. The main reasons for this are wind and precipitation.That is why an increasing number of meteorological and hydrological monitoring networks are coming together. Global coverage with hydro-meteorological measuring technology is varied. Very old and very modern (new) measuring networks are used for climate monitoring worldwide. And there are still large gaps, for example on the oceans.
Solar radiation is not only the driving force behind the Earth’s weather phenomena, it also drives photovoltaic energy production. One day of solar energy received by the Earth exceeds the amount of worldwide energy consumption per year. Exploring this merely inexhaustible source of energy - either by direct transformation of radiant energy into electricity or by indirect energy production via wind, waves, etc. - seems to be the obvious way to go. In this context solar radiation measurements are of primary...
The migration of magma towards the surface in a volcano is usually accompanied by the release of gas that was previously dissolved in the magma itself. In an open conduit volcano, most of the gas escapes through the main conduits of the volcano and then through the craters. However, a significant proportion (approximately 10%) of the total quantity of gas can escape laterally through faults and fractures that are normally present in the flanks of a volcano. Therefore, increases in the amount of gas emitted...
For survey operations up to 6000m depth (and deeper by special request), Valeport offer instruments to measure and record the classic physical parameters of Temperature, Depth, Salinity, Density, Currents and Waves. Along with the most accurate Sound Velocity sensors in the world; the ability to interface other parameters / sensors such as pH, Dissolved Oxygen Turbidity, Flourometer, Transmissometer and PAR; Housings and deployment frames to suit in-line moorings, profiling and seabed deployments, Valeport can...
Monitoring the dilution and movement of a tracer introduced into the water column provides an excellent means of determining the path that may be followed by a discharge and the rate at which dilution is likely to take place. Fluorescent dyes such as Rhodamine, Fluorescein or Agma are the most frequently used tracers for such investigations. Chelsea Technologies has been providing dye tracing systems for over 30 years. Typical applications include sub-sea pipeline leak detection, pollution studies, natural water...
NMR applications include methods that can be useful in quantifying and speciating dissolved organic matter in earth’s atmosphere, ocean, and soil (e.g., chlorofluorocarbons, benzene, toluene, ethylbenzene & xylene (BTEX), methyl tert-butyl ether (MTBE).
New geographic information system (GIS) technology tools enable you to better understand and represent the systems at work in the seas and oceans. From the coastal shoreline to the bathymetric bottom, marine GIS has been adapted and implemented to help you achieve your goals in coastal zone management, research, ocean industries, and navigation.
Oceanic and lake sciences challenge the abilities of traditional software tools. Virtually everything of interest lies beneath the surface. This is a 3D world with complex issues that affect the life in these water bodies and all life on Earth. EVS, MVS, and EnterVol’s modular toolkits provide the technology to address a myriad of surface and subsurface issues.
The quality of compressed breathing gases for aircraft, diving and marine has very tight limits imposed by bodies such as NATO and national bodies such as MOD. The test requirements are for contaminants such as CO, CO2, Total VOC, CFCs and halogenated hydrocarbons, as well as H2O and O2 content.

Fugro EMU Limited has a long established history working with the leisure industry providing first class sampling, analysis and consultancy services for a range of private and government organisations. Working on vessels, leisure complexes, beaches, swimming pools and dive sites all carried out by our in-house teams.
Over the past 20 years active fluorescence has been widely adopted by the scientific community, ecosystem managers and crop growers as a rapid and non-invasive method of estimating photosynthetic performance within a wide range of organisms, including phytoplankton (microalgae and cyanobacteria), biofilms, benthic autotrophs (corals, macroalgae and sea grasses) and terrestrial plants. The main rational for applying active fluorescence is that changes in key fluorescence parameters can reveal the early onset of...
Research programmes demand both technology and affordable products to cover studies from rivers to full ocean depth. Valeport have gained significant knowledge through close collaboration with some of the worlds leading institutes. A clear example of this is our CTD sensor fitted to the seal tags of the Sea Mammal Research Unit (SMRU) of St Andrews University, Scotland as they monitor marine mammal behaviour within their oceanic environment, by obtaining oceanographic quality CTD casts.
