Even shallow lakes stratify! In fact, they can stratify quite often - sometimes with dire consequences for the life they support. Warming from a couple of nice sunny days with low wind speeds can oftentimes be enough to cause stratification in shallow lakes. For nutrient rich lakes, hypoxia (low oxygen) in the bottom waters can form shortly after the onset of stratification - forcing much of the aquatic life in a lake to move upwards to a more oxygen rich habitat. In some bad cases, we see severe fish kills, where oxygen levels are low from top to bottom of the water column - leaving no room to escape hypoxia. An event of stratification, followed by hypoxia formation and then complete water column mixing can be short-lived in shallow lakes, and typically span from a single day to a few weeks. Traditional water sampling, such as that carried out to comply with the EU Water Framework Directive, will very often not be sufficient to capture these short-lived events. Sampling is typically carried out once per month, or bi-weekly at the most. But to capture these short-lived events, you need high-frequency data – for example data collected automatically every 15 min. through sensors installed on a floating buoy. The picture shows an example of high-frequency oxygen profiles recorded by a data buoy this summer in a typical shallow (max depth 2.6 m) Danish lake. Having such sensor system installed and running operationally through WaterWebTools can help you understand the system dynamics much better, including identifying whether an observed fish kill was caused by hypoxia, or due to other factors. If you would like to learn more about how a sensor system can be designed by WaterITech and installed in your system, please feel free to reach out, or check out our website at: https://lnkd.in/dYyeWwBR.

IDEA 4: Desalination | Ways to address the freshwater crisis Excerpt from the Popular Science Film: "Water from Air: The Path to Saving Humanity" #Watch the whole film: 🟢https://lnkd.in/e69zirqC 🔴youtu.be/0HG7kTGBIfo 97% of all the water in the world is found in seas and oceans. To obtain drinking water from them, salt needs to be removed and impurities filtered out. The idea seems simple and straightforward, but there are two problems with its widespread application. The first problem is that for every gallon of desalinated water about two gallons of hypersaline water remain. Almost always, this water is discharged back into the ocean. In areas where this water is discharged, marine life perishes. With widespread application, this would lead to the death of all marine life in the ocean. The second problem is the pipeline, – thousands of kilometers of new pipes from the ocean to consumers with all the ensuing consequences. Furthermore, there is a possibility that strong earthquakes near the San Andreas Fault could damage the pipelines. This would lead to a disaster, leaving a huge number of people without a primary source of water. These are the main methods that your specialists offer today for addressing the water scarcity issue. As we can see, there's no perfect solution. Unfortunately, that's not all the difficulties. It's time to talk about the second water-related problem. Yes, it's the second global water issue humanity is facing. Even if we obtain water from icebergs or the Great Lakes, every liter of this water will contain around 240,000 particles of micro- and nanoplastics. #Creativesociety #climate #climatecrisis #heavyrain #flood #floods #flooding #snow #water #trending #viral #survival #trending #viral #ocean #technology #drought #forest #tree #mountains #nature #ecology #environment #SundayVibes #SundayThought #SundayMotivation

Trees don’t like to breathe wildfire smoke, either – and they’ll hold their breath to avoid it https://lnkd.in/gD2tAxxR When wildfire smoke is in the air, doctors urge people to stay indoors to avoid breathing in harmful particles and gases. But what happens to trees and other plants that can’t escape from the smoke? They respond a bit like us, it turns out: Some trees essentially shut their windows and doors and hold their breath. As atmospheric and chemical scientists, we study the air quality and ecological effects of wildfire smoke and other pollutants. In a study that started quite by accident when smoke overwhelmed our research site in Colorado, we were able to watch in real time how the leaves of living pine trees responded. While scientists usually think about urban regions as being large sources of ozone that effect crops downwind, wildfire smoke is an emerging concern. Other compounds, including nitrogen oxides, can also harm plants and reduce photosynthesis. The long-term impact is still unknown The jury is still out on exactly how long the effects of wildfire smoke last and how repeated smoke events will affect plants – including trees and crops – over the long term. With wildfires increasing in severity and frequency due to climate change, forest management policies and human behavior, it’s important to gain a better understanding of the impact.

#snsinstitutions #snsdesingthinkers #snsdesingthinking Acid rain has been shown to have adverse impacts on forests, freshwaters, soils, microbes, insects and aquatic life-forms.[3] In ecosystems, persistent acid rain reduces tree bark durability, leaving flora more susceptible to environmental stressors such as drought, heat/cold and pest infestation. Acid rain is also capable of detrimenting soil composition by stripping it of nutrients such as calcium and magnesium which play a role in plant growth and maintaining healthy soil. In terms of human infrastructure, acid rain also causes paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues as well as having impacts on human health.[4][5][6][7] Some governments, including those in Europe and North America, have made efforts since the 1970s to reduce the release of sulfur dioxide and nitrogen oxide into the atmosphere through air pollution regulations. These efforts have had positive results due to the widespread research on acid rain starting in the 1960s and the publicized information on its harmful effects.[8][9] The main source of sulfur and nitrogen compounds that result in acid rain are anthropogenic, but nitrogen oxides can also be produced naturally by lightning strikes and sulfur dioxide is produced by volcanic eruptions.

Technocomm has now installed a DO (dissolved Oxygen) sensor at the same location as its Flood monitoring sensor. Dissolved DO is a direct indicator of the state of health of a river. If the values are 6+ mg/L it's an indication of a healthy river. If effluent or other chemicals are introduced into the water stream, the DO level will drop. As a general indication of ecosystems: Healthy: 6+ mg/L Stressed: 3-5 mg/L Hypoxic : 1-3 mg/L - potentially fatal conditions for many aquatic species. Anoxic: below 1 mg/L - most aerobic organisms cannot survive. Take a look at the LIVE data feed for this location here: The river Lamborn appears to be very healthy..! https://lnkd.in/e7hTP-Bu... Our FloodSense sensor remains working in place showing the river level at the same location. https://lnkd.in/eVsR8wdV...

Rising temperatures can exacerbate algae blooms by creating ideal conditions for their rapid growth. These blooms can deplete oxygen levels in water, leading to fish kills and harming other aquatic life. 🐟 👎 Additionally, some algae species produce toxins ⚠️ that pose risks to human health, making their proliferation a concern for both ecosystems and public safety. Our mission is to turn green water into clean water, but we can't do it alone! We need partners on this journey to save our planet! What questions do you have for us? Ask below! #MadeWithBLOOM #algae

The Great Lakes are home to diverse aquatic life, serving as a water source for numerous communities and an economic hub across multiple industries. However, scientists are seeing a disturbing trend of declining ice coverage across the Great Lakes, which may have disastrous implications. "Robust ice cover protects lake shorelines from high waves that can bring severe flooding and damage the coastline...Some microorganisms use the ice as a safe haven to spawn and lay eggs. A lack of ice coverage can lead to more severe snow storms because an unfrozen lake is a prerequisite for ‘lake effect’ snow," notes NOAA Great Lakes Environmental Research Laboratory physical scientist James Kessler. The decrease in ice cover highlights the importance of monitoring and tracking the health of our watershed. Cleveland Water Alliance is vested in innovative technologies that monitor and protect the health of our lake. Dan Rosenzweig-Ziff discusses the trend of declining ice coverage across the Great Lakes via The Washington Post here:
Great Lakes start 2024 with smallest amount of ice in at least 50 years
