Using Soil Sensors to Monitor Soil pH and Salinity
Background:Soil pH and salinity are two important parameters affecting plant growth and development. Therefore, monitoring these characteristics is crucial for agronomists and gardeners alike. The use of soil sensors has revolutionized the way we monitor and manage these soil properties. This paper explores the application of soil sensors in monitoring soil pH and salinity, their applications in ...

Coastal Development’s Impact on Tidal Creeks: An Ecosystem Metabolism Analysis
The steady march of progress looks different to all, but in his doctoral dissertation Sam Bickley, Ph.D., measured the effect that a certain type of progress is having on tidal creeks. Rapid development along coastal areas, particularly residential and suburban expansion, can have significant implications for the surrounding environment. While existing protections and conservation efforts can ...

Scientists Monitor Water in Everglades with Hydrostation-in-a-Briefcase - Case Study
Overview Scientists at the Everglades Science Center are studying the flow of freshwater into Florida Bay and the impact the diversion of water has had throughout the Everglades ecosystem. Their studies include corals, seagrasses, mangroves, game fishes, crocodiles, wading birds, White-crowned Pigeons and many ecosystem-level studies. Their experiments link changes in freshwater flow to ...

Linear Conversion of Conductivity To Salinity
Disclaimer: This article covers an equation for linear scaling of conductivity sensors to estimate salinity based on the Practical Salinity Scale of 1978 (PSS-78). The equation effectively estimates seawater salinity between the practical salinity ranges of 22 and 42, temperatures 5-35°C, and pressure less than 200 dBar, using a temperature-compensated conductivity sensor. This is not for ...

Managing Water Quality in Aquaculture
Introduction Annual demand of seafood has increased significantly over the past 50 years, from less than 50 million metric tons to over 175 million metric tons. Due to the unsustainable nature of fisheries catching wild seafood, the aquaculture industry has accounted for most of this increase. Industry growth is also expected in the future as the world’s meat demand continues to rise. ...

Factors Affecting Dissolved Oxygen
Introduction Regardless of what type of sensor is used to measure dissolved oxygen, there are three factors that must be accounted for to ensure accuracy. They are: Salinity Pressure Temperature Each one influences the concentration at 100% saturation but temperature is unique because it also affects how oxygen interacts with sensor membranes. The rest of this article goes over how to ...

Protecting Endangered Coral Reefs
What Reefs Do for Us Coral reefs are the source of multiple important benefits—to humans, animals, oceans, and the entire planet. Occupying less than 1% of all ocean spaces, reefs provide habitat for a full 25% of all marine species. Fish, mollusks, worms, crustaceans, echinoderms, sponges, and other marine animals all thrive in healthy reef habitats, which provide those species with ...

Study of salt content in Harlingen canals - Case Study
Antea Group uses AP-5000 for salinity measurements in Frisian surface water Commissioned by the municipality of Harlingen, Antea Group measured the salinity of the Harlingen canals in Friesland. A motorboat with an advanced mobile multiparameter probe was used to travel the length of the canals and conduct the measurements. Project Manager Jeroen Kruse talks about the project, the outcome of ...

Groundwater monitoring at the San Andres Isles - Case Study
Project Monitoring of saline intrusion, Groundwater quantity and quality. Client CORALINA (enviromental public autority of San Andres Isles) Implemented by Maser and Eijkelkamp Soil & Water Country Colombia, archipelago of San Andres Background information of the project The island of San Andres, depends currently for over 80% on groundwater for its watersupply, but its ...

The Importance of Dynamic Density Compensation in Water Level Monitoring
OBTAINING SUPERIOR WATER LEVEL ACCURACY IN COASTAL ENVIRONMENTS In-Situ Inc. water level instruments measure the sum of all pressures (atmospheric and hydrostatic) exerted on a pressure transducer and use that data to calculate water levels. Water density contributes to the total hydrostatic pressure. Saltwater has a higher specific gravity than fresh water. A standard column of saltwater exerts ...

The importance of groundwater monitoring
Groundwater monitoring is an essential element in any environmental information system. Based upon validated groundwater monitoring data, information is derived on which decisions can be made. Constant monitoring provides the necessary data input for your smart environment and is basically the basis of the decision making process concerning spatial planning and climate change adaptation. As in ...

Chemical fingerprinting of saline water intrusion into sewage lines
High salinity in sewage sludge can affect not only the operation of wastewater treatment plants (WWTPs) but also the quality of treated water generated, thereby limiting its downstream reuse. Using data on geochemical parameters, both for the central WWTP in Abu Dhabi, UAE, and literature values for potential regional saline water sources (e.g., shallow groundwater and regional Arabian Gulf ...

Salinity and miniDOT
The miniDOT and other optical dissolved oxygen sensors measure oxygen within a special plastic material that has the property of changing its fluorescence in response to the amount of oxygen present. Oxygen arrives within this material by diffusion from the surrounding environment, which is usually water. The miniDOT determines oxygen concentration in water dissolved oxygen by optically ...

Use of Electromagnetic Induction Tools in salinity assessment/appraisals in eastern Colorado
Abstract Electromagnetic induction (EMI) is a relatively low-cost and rapid method for measuring, assessing spatially soil salinity. The two studies were conducted to evaluate data obtained with a single-frequency (EM38 meter) and multi-frequency (GEM300 sensor) EMI instruments and to relate apparent conductivity measured by these instruments with the more conventional conductivity of the ...

Discrete entropy theory for optimal redesigning of salinity monitoring network in San Francisco bay
The paper presents an entropy-based method for designing an optimum bay water salinity monitoring network in San Francisco bay (S.F. bay) considering maximum-monitoring-information and minimum-data-lost criteria. Due to cost concerns, it is necessary to design the optimal salinity monitoring network with a minimal number of sampling stations to provide reliable data. The monthly data recorded ...

Surface Ocean Acidification studies using Ships Of Opportunity
Ships of Opportunity Ships of opportunity (SOOP) are used as a platform for cost-efficient collection of environmental data, Ferrybox. The SOOP network operated by NIVA cover the majority of the Norwegian coastline (from Germany (54N ) in the South to Svalbard (78N) in the North. This network is used in the national OA monitoring program. Globally, SOOPs are used for pCO2 measurements and this ...

Salinity monitoring in western Australia using remotely sensed and other spatial data
Received for publication January 27, 2009. The southwest of Western Australia is affected by dryland salinity that results in the loss of previously productive agricultural land, damage to buildings, roads, and other infrastructure, decline in pockets of remnant vegetation and biodiversity, and reduction in water quality. Accurate information on the location and rate of change of the extent of ...

Evaluation of regional groundwater quality using PCA and geostatistics in the urban coastal aquifer, East Coast of India
A systematic groundwater quality-monitoring program was conducted, and a total of 201 groundwater samples were collected. Multivariate and geostatistical techniques were employed to investigate major contamination types and its spatial characteristics in the study area. Principal Component Analysis (PCA) reveals that salinity (Factor 1) and nutrient (Factor 2) are very predominant contaminants in ...
