Will the Rickly DH-48 Integrated Sediment Sampler allow us to measure the rate at which sediment is flowing into our lake from its main tributary?
The Rickly DH-48 depth-integrated sediment sampler is designed to take continuous suspended-sediment samples. When used alone, this sampler will only measure a concentration, and not a flow rate. It is lowered from the water's surface to the bottom and raised again at a constant rate of speed to collect a depth-integrated suspended-sediment sample. The sediment-to-fluid volume can be measured to determine concentration. If it is used with a flow meter, or a velocity and depth sensor, sediment flow can be calculated.
A deep water reef off the coast of a small island in the Dutch Caribbean will be explored at depths yet to be seen by scientists, according to a press release from the Netherlands’ Wageningen University . The researchers will be mapping biodiversity and collecting samples from reefs off the coast of Bonaire. They plan to travel as deep as 300 meters to observe the biodiverse and mostly unexplored reefs. A submersible from Bonaire’s Curacao Public Aquarium will take researchers down to do their observations. The sub's sediment core sampler will help the team analyze sediment in the reefs. Biological samples will be analyzed and their DNA will be coded in a molecular lab in the Netherelands’ Naturalis Biodiversity Center.Read More
An understanding of climate change’s effects on the environment has become commonplace and grows every day, but one researcher from Florida State University is looking to answer a new question: What are climate change’s effects on people’s health? In one of the first studies of its kind, Chris Uejio, an assistant professor at FSU, and a team of researchers studied how climate change can affect the roughly 20 million Americans (according to the Environmental Protection Agency) who consume untreated drinking water on a daily basis. Because climate forecasts are predicting higher rainfall rates over the next few decades, coming down in intense storms, Uejio said those flashes could cause flare-ups in waterborne illnesses.Read More
We put together this infographic on data buoys for our Spring 2017 edition of the Environmental Monitor ( PDF available online ). Organizations across the globe use data buoy systems to observe and monitor atmospheric and oceanographic conditions in remote locations. Measurements range from air pressure, humidity, wind speed and direction to wave height, water temperature, dissolved oxygen and other water quality parameters. With the help of national and international networks, reliable and comprehensive data sets are made available for research and public safety.Read More
