Understanding and measuring eutrophication in lakes and water bodies
Eutrophication is a growing concern when it comes to water quality. It happens when water bodies become overloaded with nutrients such as nitrogen and phosphorus. This nutrient surplus can result in problems like oxygen depletion (hypoxia) and the proliferation of harmful algal blooms. Both of these issues can have severe repercussions for aquatic ecosystems. In this article, we’ll take a ...

Preventing Acid Mine Drainage: Role of Digital Temperature Sensors
Acid mine drainage (AMD), also known as acid rock drainage (ARD), is a significant environmental concern arising from the exposure of sulfide minerals in mining waste to air and water. This chemical reaction, driven by the oxidation of sulfides, leads to the generation of highly acidic waters and the release of toxic heavy metals, wreaking havoc on ecosystems and water quality. AMD’s ...

Revolutionizing Fish Farming: Harnessing the Power of Absolute Ozone Generators
As the global demand for seafood continues to surge, aquaculture has emerged as a vital solution to meet this growing need sustainably. However, fish farming comes with its challenges, one of which is maintaining optimal water quality to ensure the health and growth of aquatic species. This is where ozone technology, specifically Absolute Ozone® generators, is making a remarkable impact. ...

Effect of air pollution on plants and animals
Air pollution, emerging as a formidable adversary to global ecosystems, is primarily born from the unbridled activities of industrialisation, urban sprawl, and transport congestion. Both plants and animals, the core pillars of our ecological fabric, grapple with the multidimensional repercussions of deteriorating air quality. A profound understanding of these ramifications is imperative, ...

Deeper Insights into Marine Fish Migration Amid Global Warming
Introduction In the era of climate change, understanding the shifting dynamics of marine ecosystems is paramount. With rising global temperatures, marine fish populations are responding by altering their spatial distributions, opening up a new frontier in marine biology research. For researchers probing this environmental enigma, the Hiden HPR-40 Dissolved Species Analyzer (DSA) offers an ...

Water Pollutants Feminizing Male Fish
Hormones from birth control pills and other ’emerging contaminants’ can remain in wastewater effluent even after treatment A wide range of pollutants can contaminate freshwater systems, including physical contaminants such as plastics and microplastics, as well as chemicals, heavy metals, and other toxins. One class of pollutants, so-called “emerging contaminants,” ...

The Impact of Drought on Biodiversity
This year saw some record-breaking temperatures hit around the country, with prolonged periods of dry weather and several heatwaves during the summer… which have converged to put even more pressure on water resources all over the UK. Maximum temperatures this summer were far above average for much of England in 2022, with a new record temperature set for the UK at 40.3 degrees C, recorded ...

What is Water Transfer?
To consider the benefits of water transfer as a concept, we must first consider the issue of inequalities in water distribution around the world, something that makes water transfer and interconnection a vital part of modern-day resource management… particularly now, in the face of climate change and ever-increasing extreme weather events. Because over 70 per cent of the earth’s ...

Scotland Water Scarcity Risk Reaches ‘Significant’ Level
Businesses around Scotland are now being called upon by the Scottish Environment Protection Agency (SEPA) to implement water-saving measures across their sites, with water scarcity levels now reaching Significant in mid and north Fife. It’s possible that abstraction restrictions could be brought in by the organisation, with January 2022 the driest the east of Scotland has seen since 1940. ...

Data from the Ocean is a Big Deal: Here’s Why (and How We Can Get Better Collecting It)
It’s hard to overstate the importance of our oceans. They cover nearly three-quarters of the globe, represent a major food source, and regulate our climate. By 2030, the Organization for Economic Cooperation and Development estimates ocean-based industries will generate $3 trillion of economic activity. But in a world where data has become critical to manage every challenge and ...

Ultrasound for algal bloom control: background, research and effects
Blooming of (toxic) algae is a global problem that increases each year due to pollution and climate change. In order to restore our aquatic ecosystems, actions must be taken that address excess algal growth. Over the past years, innovations around lake restoration and algal bloom remediation have been introduced and tested. One of these methods is the use of interactive systems that control ...

Concrete Breathes New Life into Artificial Reef
A tank once used for the ASCE Concrete Canoe Competition, sponsored by the NPCA Foundation, has found new life. Florida marine life will benefit for decades to come thanks to its final resting place. A precast concrete tank designed for swamp testing the canoes was used during the 2019 competition held at Florida Tech. Participants were fascinated by the tank, and it became the backdrop for ...

The Importance of Measuring Dissolved Oxygen Levels During Summer: Low Water, High Temperatures
In a previous blog post, we explored the importance of measuring dissolved oxygen (DO) levels during the late winter and early spring, particularly after a late snowfall. The decreased DO levels which accompany cold temperatures and snowed-over surfaces can stress fish populations, sometimes to the point of winterkill. Summer, at the other end of the weather and temperature spectrum, can also ...

Monitoring Harmful Algal Blooms in Summer
Monitoring Harmful Algal Blooms Late summer is a great time to be on the water. Hot sun, clear skies and warm water draw recreationists of all stripes—boaters, kayakers, swimmers, fishing enthusiasts—to the water, looking for one last hurrah before the onset of fall. In a few, unfortunate cases, however, late summer weather can contribute to a condition that is not so delightful and ...

Golden Algae Treatment Success
The Challenge: In recent years Golden Algae has become a growing problem, causing fish kills and aquatic health issues in the fall and winter. Chemical management through the use of copper sulfate is not very effective even in the short term. In the long term, copper sulfate is toxic to many of the beneficial aquatic algae, bacteria and protozoa that can potentially compete with the golden ...

Australian desalination plant attracts fish
With growing populations and climate uncertainty, water security is a global concern. Many nations operate desalination plants, which remove salt from seawater to make it drinkable. These facilities typically discharge excess salt as hypersaline brine back into the ocean, with uncertain ecological effects. Now, researchers in Environmental Science & Technology report that a large desalination ...

Sounds of the past give new hope for coral reef restoration
Young fish can be drawn to degraded coral reefs by loudspeakers playing the sounds of healthy reefs, according to new research published today in Nature Communications. An international team of scientists from the UK's University of Exeter and University of Bristol, and Australia's James Cook University and Australian Institute of Marine Science, say this "acoustic enrichment" could be a ...
