Harmful Algal Bloom Reports for 405 lakes in New York State (USA), with antecedent weather conditions and trophic status for each lake.
Cyanobacterial harmful algal blooms (cyanoHABs) are often associated with warm water temperatures and low wind speeds, but quantifying thresholds in meteorological conditions is challenging. In an attempt to better quantify antecedent weather conditions associated with cyanoHABs, we assembled a dataset to include cyanoHAB reports from individual lakes, as well as air temperature and wind speed data on the day of, and 5 days preceding each cyanoHAB report. CyanoHAB reports were provided by the New York State Department of Environmental Conservation (NYSDEC) for 405 lakes for an 11 year period spanning 2012-2023. We used 4km gridded surface meteorological data to calculate antecedent weather conditions leading up to each report. The resulting dataset includes 4,208 cyanoHAB reports from lakes of varying trophic states in New York State (USA). We calculated anomalies in daily wind speed and air temperature for each report and the five days preceding it. The dataset is formatted as a wide table, with individual cyanoHAB reports listed by row. Each row provides report-specific data to include the date, site, trophic state of the lake, and the cyanoHAB report status. Each row contains weather data specific to the date and location of each report, with weather variables calculated from the closest grid point for each lake site. We provide 36 columns containing weather variables for each report to include air temperature and wind speed for the day of the HAB as well as the 5 days preceding it. We also provide a 24-year mean value for the day of the year (DoY), as well as the calculated difference between the day in question and the 24-year mean for the DoY.
oceandatafactory_algal_blooms_Sweden_20201018
<p>Dataset containing images of algal blooms in Swedish waters, mainly the Baltic Sea. The data is provided with a metadata description containing date, location and coordinates of each image. The images and metadata file are archived in a zip package. Images show various summer surface accumulations of so-called harmful algal blooms (HABs) or nuisance blooms. Typically, these blooms consists of Cyanobacteria in the order of Nostocales, including toxic Nodularia and non-toxic Aphanizomenon. The blooms seen in the images have however not been taxonomically annotated by microscopy analysis.</p>

As you traverse the scorching, arid desert, the sight of a blooming plant catches you off guard, a stunning symbol of defiance. Despite needing water, sunlight, nutrients, and battling a harsh environment, this plant flourishes, sacrificing many roots yet paving the way for future generations.<br><br>This resilience mirrors that of past and present immigrants, including some of our own ancestors. They faced daunting challenges to carve out better lives for their families. Today, new generations of immigrants<br>continue this relentless pursuit, driven by the hope of flourishing in new lands. They, too, will bloom!</p> <p>Corresponding artist: <a title="bpozos@gmail.com" href="mailto:bpozos@gmail.com">bpozos@gmail.com</a></p> <p> </p> <p> </p>

Fig. 5 in Insights on Short-term Blooms of Planktonic Ciliates, Provided by an Easily Recognised Genus: Cyrtostrombidium
Fig. 5. Autocorrelation function of the weekly abundance of Cyrtostrombidium at site C. Horizontal dashed lines indicate ~95% CI for significance of each autocorrelation value. The first autocorrelation is 1 by definition; it is the correlation of a sample with itself. Correlation for lags (weeks) 2, 3, and 4 falls beyond the 95% CI, indicating a persistence of 3 weeks for a peak in abundance.
