Questions & Answers

| Ask a Question
My DO% samples read low and then high to low, is this a bad reading?
The initial power up can make the first two DO% readings read low. These readings can be disregarded.
My sonde is reading a negative value for turbidity, did I calibrate incorrectly?
A sonde (even if cleaned properly) can contaminate to almost 1.0 NTU. Typically the average contaminant level ranges from 0.2 to 0.8 NTU. With this knowledge, you can enter this offset (0.5 NTU) using the sonde's One-Point Calibration feature. This calibration is only done after a two- or three- point calibration is completed. To do a One-Point Calibration after a two- or three- point calibration: Place the sonde in a container of zero standard or filtered DI water. Use of the supplied calibration/storage cup is recommended; however, any generic glass or plastic container can be used as long as the probe guard is installed. Enter the Turbidity offset as 0.5 NTU, operate the wiper and inspect for air bubbles. Wait at least 60 seconds after the last wiper to accept the calibration point.

Researchers Track Glacial Meltwater On Its Surprising Journey

While the scientific community has formed its consensus on how ice sheets are shrinking in and around Greenland, some researchers are tracking what happens to the meltwater as it drains into the ocean each summer. Their study, published in Nature Geoscience by an interdisciplinary team of biologists, oceanographers and hydrologists, used computer models to simulate the meltwater to see where currents take it and what effect it could have on the ocean. Renato Castelao, one of the researchers and an associate professor of marine science for the University of Georgia, said one of the biggest discoveries of the study was the surprising final destinations of the ice sheets as they melt into the ocean each summer.

Ice Fishing With A SondeCAM Underwater Fishing Camera

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.

Size Them Up With A SondeCAM Underwater Fishing Camera

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.
