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
Thinking of hitting the ice with a SondeCAM underwater fishing camera? Due to its rugged design, you won't have to worry about it handling the harsh elements. However there are a few simple tricks to get the most out of a FishSens SondeCAM while ice fishing. You won't have to do anything to modify the SondeCAM itself, but you are going to have to bring a few extra things. Most importantly we are going to need a power source. Unless you are hauling your gear with a truck, you'll want something more portable than the battery you used in the boat. Pick up an inexpensive and maintenance-free 12-volt, 9-amp battery. It is going to provide plenty of power, but will be much lighter and take up less space.Read More
We've all felt the frustration of weeding through a school of dinks to catch a "keeper." Often the small fish outnumber the bigger ones and they are typically more aggressive. Sometimes there's no choice but to deal with it, as is often the case with open water fishing. However a frozen lake involves a vertical presentation and a stable platform, it's a perfect situation to pick and choose which fish you want. Once you locate a school and get set up it's time to start sizing them up with a FishSens SondeCAM underwater fishing camera. It can be mind-blowing just how big some of these schools of fish are and also how outnumbered fish of a desirable size can be.Read More
