The YSI 6025 Chlorophyll Probe uses technology similar to that used by fluorometers, but the YSI sensor is much smaller, making it compatible with the probe ports in YSI's 6-Series instruments, including the YSI 6600 & 6600 V2 as well as the YSI 6820, 6820 V2, 6920, & 6920 V2. The YSI 6600 V2 sonde allows simultaneous measurement of four optical probes (dissolved oxygen, turbidity, chlorophyll, blue-green algae, and/or rhodamine), along with other parameters. The YSI 6820 V2 and 6920 V2 allow measurement of two optical probes, along with many other parameters.
Chlorophyll in various forms is bound within the living cells of algae, phytoplankton, and other plant matter found in water. Chlorophyll is a key component in the process of photosynthesis, the critical process in which energy from sunlight is used to produce life-sustaining oxygen. The amount of chlorophyll in a water sample is used as a measure of suspended phytoplankton, the magnitude of which can significantly affect the overall quality of water.
Before the new YSI sensor made in situ measurement convenient, the common way to measure chlorophyll was to collect samples and use extractive analysis in a laboratory, or take large equipment to the field. Extractive analysis methods, though highly accurate, are time-consuming and require an experienced analyst. The YSI optical, fluorescence probe is quick and efficient to use, and enables spot sampling in remote areas as well as continuous or interval monitoring.

Zooplankton drifts through the ocean, often ignored by the public in favor of more charismatic marine organisms farther up the food chain.
A new crowdsourced project aims to change that, giving anyone a closer look at small and intricate zooplankton. PlanktonPortal.org features 900,000 high resolution images of zooplankton and tasks the public to identify them as part of data processing for a collaborative study, based out of the University of Miami Rosenstiel School of Marine and Atmospheric Science.
Researchers hope the project will tell them more about zooplankton behavior, grouping and interaction.Read More
Ohio State University’s Stone Laboratory will open a new lab this summer focused on algae and water quality, according to the Ohio Sea Grant magazine Twine Line .
The new laboratory will be in the Stone Lab Research Building on Lake Erie’s South Bass Island.
Many instruments and tests will be accessible at the lab to evaluate all functions of algal blooms from photosynthesis to nutrient consumption. The lab will enable scientists to test phytoplankton, water and sediment samples on the lake instead of sending them away. This should save researchers time and money in the long run.
Lab administrators hope to increase collaborations with other research organizations and government agencies through the creation of the new laboratory.Read More
Formed by a glacier, Jordan Pond is among Maine's clearest, most beautiful bodies of water. It's also a critical freshwater resource, and watchful eyes are protecting it.
EM spoke with Dr. Rachel Fowler, Friends of Acadia's aquatic scientist, about her work monitoring Jordan Pond. A postdoctoral research scientist at the University of Maine, she is a member of a partnership among the National Park Service, the University of Maine Climate Change Institute, and Friends of Acadia that began deploying the Jordan Pond buoy in 2013. Canon provided the initial support for the project.
Friends of Acadia is a nonprofit organization that supports different projects in the park.Read More
