The YSI 6425AF Chlorophyll Probe expands YSI's suite of sensors for multi-parameter, water quality monitoring applications. The new probe is designed to estimate phytoplankton concentrations by detecting the fluorescence from chlorophyll in situ. The data can be useful in predicting detrimental algae blooms and, indirectly, in determining nutrient loading in environmental applications. The probe features a mechanical self-wiping capability for long-term monitoring.

TheYSI 6425AF 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.

Plankton Portal enlists public to classify thousands of zooplankton images

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.

Algae monitoring begins for Indiana lakes

Indiana Department of Environmental Management officials are starting their statewide algae inspections, according to an article from Indiana Public Media. During the next two weeks, state officials plan to measure algae concentrations in 13 state parks. Indiana environmental officials collect water samples in each lake in the park. They test the samples for blue-green algae.  If they find concentrations of algae greater than 100 million cells per liter, the lake will be closed to recreation for a minimum of two weeks.

Sewage an Unseen and Ignored Threat to Coral Reefs and Human Health

It’s an open, dirty secret that the ocean is used as the ultimate sewage solution. Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up. “This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.
