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.

Increased snow growing Himalayan glaciers in spite of warming temperatures

Scientists say Asia’s glaciers are growing instead of shrinking as a result of increased snow, according to a report from Live Science . The glaciers in the Karakoram region of the Himalayas have remained uniform in spite of climbing temperatures and melting glaciers elsewhere. To determine the cause of the glaciers’ resilience, the research team paired current temperatures and precipitation data with climate models for three regions within the Himalayas. They found that Karakoram’s location ensures that it receives large amounts of snow during the winter. The researchers speculate that the snow will help keep the glaciers stable until 2100. But if temperatures continue to rise, glaciers may begin to melt.

Updated global ocean floor map depicts structures in greater detail

A new map from Scripps Institute of Oceanography researchers depicts the global ocean floor in unprecedented detail, according to a report from Scientific American . The map’s resolution is approximately 5 kilometers, making objects 5 kilometers and larger visible. To create the map, researchers used data from Cryosat-2 and Jason-1 satellites to measure sea surface height, determine the floor’s layout and pick up landscape features. However, the satellites can’t measure the sea floor directly because the water’s interference. Although the new map is more detailed than previous works, maps of Mars or the moon have higher resolutions.

Federal lab seeks larger ocean acidification monitoring buoy network

The world’s oceans are becoming increasingly acidic, threatening not only countless marine organisms but also the livelihoods of millions of people in the fishing industry. Over 36,000 commercial fishing vessels operate out of the U.S. alone, many of which trawl the Pacific for salmon, herring and shellfish. The Pacific Marine Environmental Laboratory, a research branch of the National Oceanic and Atmospheric Administration, is hoping to expand their network of long-term monitoring buoys to better meet the challenges posed by ocean acidification. “While the ocean is always a challenging place for a buoy, the recession has been a recent challenge for the science community as well,” said Adrienne Sutton, a lead scientist in PMEL’s carbon group.
