Questions & Answers

| Ask a Question
I turned on the YSI 5100 meter which has a YSI 5905 probe attached. The reading came up all zeros. Turned off and on a few times, wiggled the cord and it corrected itself. What could be the cause?
It sounds like there is a short in the cable that is causing a communication issue between the probe and the meter. We can evaluate the probe at no cost to verify the failure. Click the Support link above for instructions on returning the probe for evaluation.
How is the probe powered?
The 5905 probe is powered by an attached DO meter. However, the stir paddle must be plugged into its power adaptor to operate, as it is not powered by the meter.
What meters is this BOD probe compatible with?
The 5905 BOD probe is compatible with four YSI dissolved oxygen meters: Models 52, 58, 5000 and 5100 . If used with benchtop models 5000 or 5100, the YSI 5011 adaptor is required.

National Ecological Observatory Network Installs New Buoys At Two Florida Lakes

A national water quality monitoring network has added two lakes to its coverage with the installation of new in-situ sensor buoys at each site. Last June, the National Ecological Observatory Network, working with the Ordway-Swisher Biological Station, fitted aquatic sensors to buoys at Suggs Lake and Barco Lake in Florida, providing useful hydrological and meteorological data through the network’s open access web portal. “These sensors will provide continuously streaming data about the physical, chemical and biological environments of these lakes,” said Charles Bohall, associate scientist with NEON. “The sensors are stationed at the surface of the lake most of the time, but every six hours will take a profile of the entire water column.

Scientists Accidentally Discover Darwin Finches’ DIY Insect Repellent

During a separate field study, University of Austria scientists made a surprising discovery, according to a recent New Scientist article . The research team discovered that Darwin finches living on the Galapagos Islands have found a natural way to protect themselves from life-threatening mosquitoes and parasitic flies that prey on their young. The scientists observed the finches rubbing their feathers with leaves from a guava tree. The researchers found that the guava leaves repelled mosquitoes, parasitic flies and stunted their larvae. Birds and other animals reportedly use plants to keep insect pests away, but this is the first time they have been observed doing so.

Manmade Global Warming Eclipses 1,800 Years Of Global Cooling

According to a University of Maryland press release , an examination of multiple studies covering the globe showed scientists that the reversal of a 1,800-year global cooling trend was caused by human activity that resulted in global warming. Researchers examined 57 studies of ocean surface temperature data covering a 200-year span over the entire globe. The cooling trend was believed to be largely the result of frequent volcanic activity which spurred a significant cooling trend. The trend also was due to the tendency of oceans to change temperature slowly, as opposed to land masses, which change temperature more quickly. Due to human influence, however, the globe is warming 20 times faster than it cooled for the 1,800 years previously, researchers discovered.
