AMS 5/8" Threaded Multi-Stage Sludge Sampler
- Valved core tip fills the sampler without losing the sample upon retrieval
- Flap cap allows excess air and water to escape through the top of the sampler
- Up to 4 optional 12" sections can be added to the sampler

|Drop ships from manufacturer|
During deployment , the flap cap opens and allows excess air and water to escape through the top of the sampler eliminating pressure buildup. The sediment enters and fills the liner. When the sampler is lifted the flap closes and creates suction to assist the soil core catcher in retaining the sample. Up to 4 optional 12" sections can be added.
- (1) Multi-stage flap check cap
- (1) Multi-stage sludge core tip
- (1) 12" multi-stage SCS base
- (1) 2" x 12" plastic liner
- (2) Plastic end caps
- (1) 2" soil core catcher
- (1) Universal slip wrench

A team of researchers led by scientists from the University of South Carolina Dornsife traveled to the Peruvian jungle to understand how sediment and plant matter travel down the Andes Mountains and into the Amazon River system, according a first-person account from Sarah Feakins, assistant professor of earth sciences at USC Dornsife.
The team focused on a tributary to the Amazon River, the Kosnipata River. They started at the headwaters, traveling up treacherous gravel mountain roads. They ended in the Amazonian floodplain, where Feakins said the river was orange from colloids in the soil.
The team spent most of their time collecting and filtering water to obtain sediment samples. Feakins described the work as collecting by day and filtering by night.Read More
A new report authored by researchers from the University of Nebraska-Lincoln suggests that the use of inorganic nitrogen and phosphorus for fertilization improves crop yields, but can have negative impacts on soil quality, the American Society of Agronomy has reported .
A study of crop lands in western Kansas has shown that inorganic fertilization increases organic carbon stocks while damaging soil’s structural quality.
Researchers collected soil samples from experimental fields fertilized with various amounts of inorganic fertilizers to determine how different nutrient levels might impact soil quality. The results showed that applying nitrogen and phosphorus at high rates can expedite soil erosion and cause other structural issues.Read More
River management is inherently complex, demanding mastery of constantly dynamic conditions even when the climate is stable. As the climate changes, however, river management will become even more difficult and unpredictable—and old models and techniques are likely to fail more often.
Now, researchers from around the world are calling for attention and change to how we manage and model the rivers of the world. Dr. Jonathan Tonkin , a Rutherford Discovery Fellow at New Zealand's University of Canterbury , spoke to EM about why he is arguing that current tools for river management are no longer enough as even historical baseline river ecosystem conditions themselves are changing.
