Overview
The YSI 6025 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.

Compact
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 the measurement of two optical probes, along with many other parameters.

Simplified Sampling
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. The YSI 6025 Chlorophyll Probe enables spot sampling in remote areas as well as continuous or interval monitoring.

Questions & Answers
How can I ensure that I'm getting the most stable readings during an unattended study?
During unattended studies, the stability can be improved by increasing sampling frequency. To change the frequency settings, Go to Advanced Menus-->data filter-->frequency-->time constants and change the time constant to 30 seconds.
Should I use the wiper during calibration?
Yes, the wiper should be run at least once during calibration. The calibration reading should not be accepted until at least 30 seconds after a wipe.

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.

Stone Laboratory to open new algae focused water quality lab

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.

CastAway Doubts about Conductivity, Depth and Temperature Monitoring

The Sontek CastAway-CTD is a castable device that measures conductivity, temperature and depth. The instrument has been used in the field for over a decade by oceanographers, limnologists, divers, fishers and educators. There have been few changes since the first iteration in 2010, showing that the instrument is durable and accurate without requiring new models.   The CastAway is the first conductivity, temperature and depth (CTD) instrument of its kind. While other CTDs are large and cumbersome to deploy, with cages and isolated sensors, the CastAway is a small, lightweight and easy-to-use instrument. Typical CTDs utilize pumps to ensure water flows over the sensors during deployment.
