Stone Lab is one of the leading groups in algal bloom research on Lake Erie and other lakes in Ohio.<\/p>\n<p>For more than 100 years, Stone Lab has conducted biology research and provided science education and outreach to the region. Over the years, thousands of individuals of varying ages have learned from the resources Stone Lab provides.<\/p>\n<p>Stone Lab\u2019s Research Coordinator and Senior Researcher, Justin Chaffin, learned of Stone Lab while an undergraduate student at Bowling Green State University Fireland Campus. During his research experience at Stone Lab, Chaffin learned a great deal about HABs and enjoyed the combination of fieldwork and lab analysis, choosing to remain there as a researcher after completing his studies.<\/p>\n<div id=\"attachment_38513\" style=\"width: 950px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-38513\" class=\"size-full wp-image-38513\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2024\/07\/Chaffin_KIMG1951_ForWeb.jpg\" alt=\"Chaffin\u2019s crew collecting water samples aboard the R\/V Erie Monitor\" width=\"940\" height=\"705\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_KIMG1951_ForWeb.jpg 940w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_KIMG1951_ForWeb-300x225.jpg 300w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_KIMG1951_ForWeb-600x450.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_KIMG1951_ForWeb-768x576.jpg 768w\" sizes=\"auto, (max-width: 940px) 100vw, 940px\" \/><p id=\"caption-attachment-38513\" class=\"wp-caption-text\"><span style=\"color: #808080;\">Chaffin\u2019s crew collecting water samples aboard the R\/V Erie Monitor.

Over the years, Chaffin has managed shorter-term studies and overseen the long-term real-time monitoring efforts occurring at the lake.<\/p>\n<p>One of the more recent projects that Stone Lab has assisted in is the creation of a <a href=\"https:\/\/www.fondriest.com\/news\/when-green-isnt-good-cyanobacterial-toxin-knowledge-and-toxicity-forecast-high-on-stone-labs-list-of-research-pursuits.htm\" target=\"_blank\" rel=\"noopener\">microcystin toxicity forecast<\/a> for Lake Erie. The NOAA-led initiative sought to identify what controls how fast <em>Microcystis<\/em> produces microcystin. The data will then be used to construct a model that forecasts microcystin concentrations.<\/p>\n<p>Chaffin explains, \u201cThe main thing we looked at is how cyanobacteria produce toxins. Why? When do they produce toxins? Where, and at what rate, are they producing toxins?\u201d He continues, \u201cThen we look at the why. What environmental factors are associated with that? Is it temperature? Is it light, phosphorus or nitrogen levels? Is it pH? What triggers cyanobacteria to produce toxins?\u201d<\/p>\n<p>The model will become a useful resource to water treatment operators, beach managers, and news media, who can report to the public toxicity and where to go on the beach to avoid blooms.<\/p>\n<div id=\"attachment_38515\" style=\"width: 950px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-38515\" class=\"wp-image-38515 size-full\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2024\/07\/Chaffin_Hans-and-BGSU-Justin-2023_ForWeb.jpg\" alt=\"Researchers from the University of North Carolina and Bowling Green State University at Stone Lab setting up an experiment.\" width=\"940\" height=\"529\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_Hans-and-BGSU-Justin-2023_ForWeb.jpg 940w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_Hans-and-BGSU-Justin-2023_ForWeb-300x169.jpg 300w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_Hans-and-BGSU-Justin-2023_ForWeb-600x338.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_Hans-and-BGSU-Justin-2023_ForWeb-768x432.jpg 768w\" sizes=\"auto, (max-width: 940px) 100vw, 940px\" \/><p id=\"caption-attachment-38515\" class=\"wp-caption-text\"><span style=\"color: #808080;\">Researchers from the University of North Carolina and Bowling Green State University at Stone Lab setting up an experiment.

In 2016-2019, an additional buoy was deployed in a separate part of the basin in order to gather more data on conditions in other areas of Lake Erie.<\/p>\n<p>In an ideal season, the real-time data allows researchers like Chaffin to view lake conditions <a href=\"https:\/\/www.fondriest.com\/news\/before-and-after-harmful-algal-blooms-long-term-monitoring-and-modeling-in-otsego-lake.htm\" target=\"_blank\" rel=\"noopener\">before, during, and after cyanobacterial blooms<\/a>. Being able to look over the collective data makes it easier to identify triggers of HABs.<\/p>\n<p>Stone Labs\u2019 monitoring program includes grab sampling to ensure the buoy\u2019s data accuracy and to bridge the gap in data during the off-season, when the buoy isn\u2019t deployed, due to lake conditions that could possibly damage the equipment.<\/p>\n<p>In 2024, Stone Lab will deploy the newer buoy, a <a href=\"https:\/\/www.nexsens.com\/products\/data-buoys\/cb-1250\" target=\"_blank\" rel=\"noopener\">NexSens CB-1250<\/a> equipped with a <a href=\"https:\/\/www.nexsens.com\/products\/sensors\/water-quality\/ysi-exo2-multi-parameter-water-quality-sonde\" target=\"_blank\" rel=\"noopener\">YSI EXO2<\/a> and <a href=\"https:\/\/www.nexsens.com\/products\/data-loggers\" target=\"_blank\" rel=\"noopener\">X2-CB data logger<\/a>. The sonde collects data on various parameters known to influence and be indicators of cyanobacterial blooms, such as total algae and cyanobacteria levels, water turbidity, temperature, pH, fDOM, dissolved oxygen, and specific conductivity. Data from the sonde is logged every 15 minutes and then transferred to the cloud, where it is viewable from <a href=\"https:\/\/www.nexsens.com\/products\/software\/web-datacenter\" target=\"_blank\" rel=\"noopener\">WQData LIVE<\/a>.<\/p>\n<p>Stone Lab also grows algae in laboratory-scale incubators, allowing for a controlled environment where the impact of various influences can be tested. Stone Lab also has a mesocosm facility with fifteen 600-gallon tanks that are used for a similar purpose but allow for much larger-scale testing.<\/p>\n<div id=\"attachment_38511\" style=\"width: 950px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-38511\" class=\"size-full wp-image-38511\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2024\/07\/Chaffin_Buoy-2024_ForWeb.jpg\" alt=\"Pictures of our buoy in the water after deployed from the R\/V Gibraltar III\" width=\"940\" height=\"549\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_Buoy-2024_ForWeb.jpg 940w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_Buoy-2024_ForWeb-300x175.jpg 300w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_Buoy-2024_ForWeb-600x350.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_Buoy-2024_ForWeb-768x449.jpg 768w\" sizes=\"auto, (max-width: 940px) 100vw, 940px\" \/><p id=\"caption-attachment-38511\" class=\"wp-caption-text\"><span style=\"color: #808080;\">Pictures of our buoy in the water after being deployed from the R\/V Gibraltar III.

Researching cyanobacteria behaviors is one step in ensuring that water bodies like Lake Erie are able to continue being used recreationally and for drinking water.<\/p>\n<p>Chaffin explains, \u201cWe\u2019re learning that these toxins can be volatilized and get in the air. So just standing on the beach can expose you to the toxins, but the main focus has been on producing safe drinking water. Ultimately, it comes down to people, and everyone needs access to clean water. Bottle water is expensive and wasteful. And most people like to play in the water. Whether it\u2019s swimming or boating, fishing, or you\u2019re strolling along the beach, everyone needs fresh water.\u201d<\/p>\n<div id=\"attachment_38509\" style=\"width: 950px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-38509\" class=\"size-full wp-image-38509\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2024\/07\/Chaffin_KIMG2313_ForWeb.jpg\" alt=\"Researchers in Stone Lab\u2019s mesocosm facility. \" width=\"940\" height=\"529\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_KIMG2313_ForWeb.jpg 940w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_KIMG2313_ForWeb-300x169.jpg 300w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_KIMG2313_ForWeb-600x338.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2024\/07\/Chaffin_KIMG2313_ForWeb-768x432.jpg 768w\" sizes=\"auto, (max-width: 940px) 100vw, 940px\" \/><p id=\"caption-attachment-38509\" class=\"wp-caption-text\"><span style=\"color: #808080;\">Researchers in Stone Lab\u2019s mesocosm facility.
