Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...
Although computer models of wind flow over terrain have improved dramatically in the past few years, there is still no substitute for data recorded at the site. So you want to build a wind farm. Good for you. With the global drive towards a low carbon economy, it is surely the right way to go for many individuals, companies and, indeed, Governments around the world. As information from the ...
The MWRA is a state government agency that provides wholesale water and sewer services to 2.5 million people and more than 5,500 large industrial users. It also monitors outflows in Cape Cod Bay and Boston Harbor using a range of advanced technologies. As an industrial user of electricity, agency officials are looking to reduce economic volatility from electricity costs and to improve energy ...
Our current pattern of resource use is leading to the depletion and, consequently, scarcity of natural resources (1), the degradation of ecosystems and volatile and increasing prices of natural resources. On a planet with finite resources, the challenge is to find a way of delivering greater value and more services with fewer inputs (EC, 2011a). Resources are defined as raw materials, such as ...
Civil infrastructures are usually monitored through its whole life cycle. SHM (Structural Health Monitoring) technologies enable the estimation of the structural state and detection of structural change that affects the performance of a structure. Two discriminating factors in SHM are the time-scale of the change (how quickly the state changes) and the severity of the change. These factors ...
Recovery of free-product petroleum at the former St. Croix Alumina (SCA) site in Kingshill on St. Croix, VI, is addressing ground-water contamination caused by past releases of fuel and refined petroleum at SCA. The oil recovery system employs wind-driven turbine compressors (WTCs), wind-driven electric generators (WEGs), and photovoltaic (PV) panels to power pneumatic and electric submersible ...
River flood alert and water reservoir managements are global growing requirements. SolidAT offers a full or partial solution (according to the customer's requirements) that can save lives and damage to property inflected by river floods. Moreover we provide real time water reservoir level and capacity. Awareness of governments and municipalities world wide is growing. Below is described a case ...
A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...
Good Neighbours Limit their Noise Impact Long-term noise monitoring has taken place in various applications for many years. Business such as airports, power stations, refineries, mines, etc., may be required to perform continuous noise monitoring to ensure legal operating conditions are not breached, and to demonstrate to local authorities and communities that the business continues to be a good ...
The Office of Meteorology and Hydrology in Mexico equipped a vehicle with measurement technology for verification of their Hydro-Met stations. We are proud that they decided to choose our smart WS501 compact weather station (All-in-one) for measurement of the meteorlogical parameters. With the integration of the smart weather sensor WS501-UMB the calibration vehicle can provide accurate data ...
Globally, ecosystems are subjected to prolonged droughts and extreme heat events, leading to forest die‐offs and dominance shifts in vegetation. Some scientists and managers view soil as the main resource to be considered in monitoring ecosystem responses to aridification. As the medium through which precipitation is received, stored and redistributed for plant use, soil is an important factor ...
Like many research programs, our LTER site is continually struggling to manage numerous remote sensor stations and their data . We are constantly looking to improve the quality and availability of the data they are collecting while using technician time and resources effectively. One option on the market to manage sensor network data is Vista Data Vision (VDV) and after some initial testing, we ...
Underwater exploration, fish farms, dive jobs, marine research, municipal and commercial water utilities are obvious industries for the utilization of Deep Trekker mini-ROVs and pipe crawlers. However another industry that has seen remarkable success integrating underwater inspection robots is energy production. Diverse methods of creating energy provide a number of applications which benefit ...
Soils can be highly variable in terms of CO2 flux values. Even at a seemingly uniform site, the soil CO2 flux might range from 2 μmol/m2/s at one location to over 4 mol/m2/s just a few meters away. To obtain reliable site mean flux values, it is important to determine how many readings might be required so that time and resources can be properly allocated before starting an investigation. In ...
The Missouri Department of Natural Resources (MoDNR) and Washington University participated in a project to collect and analyze air toxics metals data. It was funded through a Community Air Toxics Grant from the U.S. Environmental Protection Agency (USEPA). The study grew out of the southside St. Louis Community Air Project (CAP) which identified six hazardous air pollutants of concern including ...
AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...
ABSTRACT The current lack of empirical data on outdoor tobacco smoke (OTS) levels impedes OTS exposure and risk assessments. We sought to measure peak ...
L3.1 | Chemical Security: Sustainable Utilities through a Secure Power Grid Jeff Simmerman | Lieutenant Commander USCG (ret), ERM On Christmas Day 2009, a young radicalized Detroit-bound passenger on a Northwest (NW) Flight 253 attempted to become a bomber aboard that flight with a liquid explosive. This liquid ...
Many of the Environmental Protection Agency's (EPA's) methods used to monitor air, water and soil for environmental contaminants prescribe step-by-step details on how the chemical analysis must be conducted and prohibit any deviations or variations. The EPA has recognized that monitoring equipment and technology have improved tremendously over the last few years; that environmental media do not ...
The U.S. EPA revised the primary National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2) on June 2, 2010 by implementing a new 1-hour standard of 75 parts per billion (ppb) (calculated as the three-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations). Based on an evaluation of the risks posed by acute exposure to SO2, EPA ...
