Plastic Debris Wreaks Havoc in the Pacific Ocean

As he crossed the Pacific Ocean, what Charles Moore discovered in 1997 (and shortly thereafter was named the Great Pacific Garbage Patch), exists within the confines of the North Pacific subtropical gyre. There are five major ocean gyres around the globe that have existed and evolved with the shifting of the tectonic plates since the beginning of time. Formed by global wind patterns and the forces created by the Earth’s rotation, ocean gyres have a tendency to collect debris – which up until modern times has consisted of natural material.

Gulf of Mexico ‘dead zone’ is the largest ever measured | National Oceanic and Atmospheric Administration

June outlook foretold New Jersey-sized area of low oxygen

Kyle Taylor's curator insight, October 17, 2017 4:55 PM
This article explores a grim discovery made in the Gulf of Mexico, the Gulf was previously known to have a large dead zone but, scientists have now discovered it is much larger than anticipated. A dead zone is an area in a body of water with very little to no oxygen, the amount of oxygen available in dead zones is insufficient for any aquatic organisms to live. The estimated size of this dead zone appears to be the size of New Jersey and is by no means natural. Land runoff and pollution has made its way down the Mississippi rivers and into the gulf which has now generated a massive body of water that is essentially lifeless. This case study is an example of poor water quality management and a lack of awareness, in order to fix this problem it will require immense amount of time and money which is something the United States is likely unwilling to accommodate with. Immediate action will be required by states responsible for this disaster to reduce their annual pollution in an attempt to lessen the damage that has already been done.

Top 6 Reasons to Upgrade Your Model 55 DO Meter to a Pro20i

Top 6 Reasons to Upgrade Your Model 55 DO Meter to a Pro20i | Water quality | Scoop.it
YSI offers many instruments that measure dissolved oxygen (DO), but there are two dissolved oxygen instruments that are ideal replacements for the Model 55 – the YSI Pro20i and the YSI Pro20. These instruments measure DO with an electrochemical sensor, just like the Model 55. The only difference between the Pro20i and Pro20 is the cable, as the Pro20i features an integral (i.e. built-in) cable like the Model 55. This integral cable keeps the cost low and makes the Pro20i the direct replacement for the 55.

Drilling into the Abyss | Understanding Sea Level Rise

A rapid increase in sea level is a real threat if the larger ice shelves in the Antarctic disintegrate due to heat transportation from ocean currents.

Following a disintegration of the ice shelves, the inland ice could move freely into the ocean causing an accelerated rise in sea level. Are the ice shelves heading for a quick disintegration? Or, are they actually growing, gaining and becoming more stable? The answers lie below the 700 meter thick ice cover of the Filchner-Ronne Ice Shelf.

Iceland Stream Warming Study Provides a Preview of Climate Change

Because of its unique geology and hydrology, the Hengill region in Iceland provides a remarkable view of the past in the newly hewn volcanic landscape with fresh, shallow soils. It also offers a peek at the future, as scientists warmed streams and enriched them with nutrients to study the effects that global climate change could have on rivers around the world.

Combating CAFOs | Concentrated Animal Feeding Operations and Water Quality

Concentrated animal feeding operations (CAFOs) are colossal facilities where thousands of animals are raised for consumption. In the United States, North Carolina is one of the top players when it comes to production of swine and poultry by using these types of operations. But, with that high ranking comes high risks for North Carolinians.

What Does an EPA Approved Method Really Mean?

We’ve all heard that test methods used for compliance reporting in drinking water and wastewater plants should (must!) be approved by the EPA, but what does that actually mean?
To keep it simple, municipalities and other entities must comply with their permit under the Clean Water Act (CWA) and the Safe Drinking Water Act (SDWA) before water leaves their facility. These major acts were passed in order to protect the health of humans and our nation’s water supply.

Life After Deepwater Horizon | Remediation Efforts on the Gulf of Mexico

Great organizations like The Water Institute of the Gulf and Dauphin Island Sea Lab are putting in real work to help ensure the health of the extremely important Gulf of Mexico Coast ecosystem. See how the two organizations, along with Xylem, are helping put the pieces back together.

On Tuesday, April 20, 2010 the largest oil spill in history occurred when a sudden explosion and subsequent fire occurred on the Deepwater Horizon Platform, located 50 miles southeast of Venice, Louisiana. Lisa Landry, Gulf Coast Applications Specialist for Xylem, was on the ground the weekend after the explosion, serving as an oiled wildlife transporter.

Water Flow Data Helps Steer Florida Spring's Recovery

Silver Springs—a network of two dozen or more springs in central Florida—bubble up through central Florida’s Karst formations, limestone beds that have been carved by acidic groundwater and rain into baroque networks of caves, channels, domes and tunnels. Channels in the matrix flow with underground rivers and provide quick conduits between surface water and shallow groundwater. As domes collapse and sinkholes form, ancient paths are rerouted beneath the surface. That makes flow studies incredibly complex, and makes the once-pristine Silver Springs and Silver River system highly sensitive to pollution.

Kyle Taylor's curator insight, October 17, 2017 4:49 PM
This article explores the case of the Florida springs which consists of a network of over two dozen streams and is made up of a very complex stream and river system. Due to the complexity of these streams and river systems it made flow studies very complex and difficult to administer however, Mitch Wainwright a Florida native has compiled data charts and other data sets to assist hydrographers direct the flow of the springs in order to improve water quality. The water quality of these springs has depreciated over time and she took it upon herself to help improve the quality of this river using a variety of GIS tools and in-situ research. This is another example of how water quality management can be tackled by everyday citizens who are interested in improving the water quality of their local water bodies.

Waterkeepers at the Third Pole | Protecting the Himalayas

Waterkeepers at the Third Pole | Protecting the Himalayas | Water quality | Scoop.it
The melting of snow in the Arctic and Antarctic due to global climate change is reported frequently, but the melting of the Himalayas’ glaciers has gone largely unreported, even though far more people are affected. The glaciers of the Himalayas are, in fact, the "Third Pole.” They feed the giant rivers of Asia that support half of the world’s population.

Kyle Taylor's curator insight, October 17, 2017 4:35 PM
This article addresses the unreported melting of glaciers in the Himalayas, what is considered by many as "the third pole". The water supply feeds into the rivers of Asia and support almost half the worlds population. The melting of these glaciers is currently resulting in increased water levels and is threatening many small communities located throughout the Himalayas. To protect these small communities it will be a colossal challenge because it is all a result of climate change and until something can be done about that, there will likely be very little progress made in terms of slowing down the melting of glaciers. This website details more of the parameters around the quality of water found within different sections of the Himalayas and is a relevant case study to the topic at hand.
