Winter survey data from Lake Erie from Nov 2024 to Mar 2025 Dataset Description: Methods and Sampling: <p>The vessel came to a stop when the predetermined sampling station was reached, at a time decided on by the ship's command. The location and time of sampling were recorded, as well as the environmental conditions. The trained crew members of the vessel then used a YSI water quality sonde to collect data that were recorded. A Secchi disc with measurement indicators every 10 centimeters were then deployed, and recordings were taken on both the upcast and downcast. A Van Dorn water sampler was then used to collect water at a depth of 1 meter. Water samples were then transferred to 1-liter (L) polyethylene storage bottles or 2 L plastic storage bottles, and stored in a dark place at 4 degrees Celsius until picked up by personnel on the same day. The samples were then transported in dark coolers containing ice packs to Bowling Green State University (BGSU) or the University of Windsor (GLIER). Samples were also collected from Mitchell's Bay (a land-based sampling location) using the same methods and observational conventions.</p>
<p>Sub-samples for chlorophyll a were taken in the laboratory using 0.45 micrometer (um) nylon and 20 um polycarbonate membranes and a vacuum filtration system. The filter was placed in a screw cap polyethylene centrifuge tube and stored in a dark freezer until extraction. The samples were extracted using 90% acetone and kept at -20 degrees Celsius for 24 hours, and chlorophyll was measured using a TD-700 fluorometer (Welschmeyer, 1994).</p>
<p>Total and dissolved nutrient samples were held in acid-washed 250 milliliter (mL) polyethylene bottles and stored in a dark freezer at -20 degrees Celsius until they were ready to be analyzed. Dissolved nutrient sub-samples were taken by filtering the agitated sampled water through 0.22 um filters. The frozen samples were then shipped on ice to the National Center for Water Quality Research at Heidelberg University (Tiffin, OH). Microscopy was performed on raw water samples that were preserved with 5% Lugol's iodine solution. These samples were stored at room temperature in the dark until shipped and analyzed by Aquatic Taxonomy Specialists (Malinta, OH).</p>

Lake Erie Center for Fresh Waters and Human Health
<p><em>NSF Award Abstract:</em><br />
The Lake Erie Center for Fresh Waters and Human Health is a five-year, multi-institutional effort aimed at understanding the environmental factors and ongoing changes that influence the growth and toxicity of cyanobacterial harmful algal blooms (cHABs) in Lake Erie. The Center will support three research projects. Specifically these projects address the following aims: first, how environmental cues promote or constrain the proliferation of cHAB species in mixed populations; second, how environmental cues influence toxin production by cHAB species; third, how other member of the microbial assemblage influence cHAB growth and toxicity. The Center will provide a Community Engagement Core to lead outreach activities that will inform the general public on the effects of cHABs by efforts that include: (1) a community engaged scholarship training for scientists associated with the Center, (2) community-engaged scholarship training for practitioners or community members associated with the Center, and (3) a stakeholder needs assessment for Great Lakes and environmental health literacy to inform general outreach information needs. A citizen science engagement with charter boat captains will further develop a near real-time database on cHAB severity in Lake Erie, and the Facilities Core will provide metadata that not only serve the three stated research projects, but also yield a database available to all Great Lakes scientists. The outcomes are to involve community stakeholders and researchers in the Great Lakes on issues regarding human health, climate change and awareness of threats to our fresh water resources.</p>
<p>The Center is jointly supported by NSF and by the National Institute for Environmental Health Sciences (NIEHS).</p>
<p>This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.</p>

dataset
<p>The vessel came to a stop when the predetermined sampling station was reached, at a time decided on by the ship's command. The location and time of sampling were recorded, as well as the environmental conditions. The trained crew members of the vessel then used a YSI water quality sonde to collect data that were recorded. A Secchi disc with measurement indicators every 10 centimeters were then deployed, and recordings were taken on both the upcast and downcast. A Van Dorn water sampler was then used to collect water at a depth of 1 meter. Water samples were then transferred to 1-liter (L) polyethylene storage bottles or 2 L plastic storage bottles, and stored in a dark place at 4 degrees Celsius until picked up by personnel on the same day. The samples were then transported in dark coolers containing ice packs to Bowling Green State University (BGSU) or the University of Windsor (GLIER). Samples were also collected from Mitchell's Bay (a land-based sampling location) using the same methods and observational conventions.</p>
<p>Sub-samples for chlorophyll a were taken in the laboratory using 0.45 micrometer (um) nylon and 20 um polycarbonate membranes and a vacuum filtration system. The filter was placed in a screw cap polyethylene centrifuge tube and stored in a dark freezer until extraction. The samples were extracted using 90% acetone and kept at -20 degrees Celsius for 24 hours, and chlorophyll was measured using a TD-700 fluorometer (Welschmeyer, 1994).</p>
<p>Total and dissolved nutrient samples were held in acid-washed 250 milliliter (mL) polyethylene bottles and stored in a dark freezer at -20 degrees Celsius until they were ready to be analyzed. Dissolved nutrient sub-samples were taken by filtering the agitated sampled water through 0.22 um filters. The frozen samples were then shipped on ice to the National Center for Water Quality Research at Heidelberg University (Tiffin, OH). Microscopy was performed on raw water samples that were preserved with 5% Lugol's iodine solution. These samples were stored at room temperature in the dark until shipped and analyzed by Aquatic Taxonomy Specialists (Malinta, OH).</p>

<p>The meteorological data was taken directly from readings using vessel instruments, marine forecasts, and expert observations. The physico-chemical data was obtained using a YSI 600QS multiparameter sonde, and nutrient concentrations were analyzed at the National Center for Water Quality Research at Heidelberg University. Fluorometric classification of phytoplankton was measured using a FluoroProbe (bbe Moldaenke GmbH, Schwentinental, Germany), and plankton taxonomic classification and cell enumeration was conducted by Aquatic Taxonomy Specialists (Malinta, OH). The extractive chlorophyll was read using a TD-700 Fluorometer (Turner Designs Inc., San Jose, CA), the sample concentrations were then calculated with the equation below, and the averages for each site were calculated from the triplicate samples.</p>

This section documents curation actions performed by BCO-DMO and additional information relevant to understanding and reusing this dataset. It distinguishes changes made to the submitted (meta)data from unresolved issues and/or enhancements that improve future reuse and interoperability.
CURATION ACTIONS PERFORMED ON DATA
- Imported original file "winter_lake_erie_2025_metadata.csv" into the BCO-DMO data processing system.
- Treated "-" as a missing data value (missing data values are empty/blank in the final CSV file).
- Created new column ISO_DateTime_Local by combining date (format %m-%d-%Y) and time_edt (format %H:%M) columns into a datetime with output format %Y-%m-%dT%H:%M.
- Converted date column format from %m-%d-%Y to %Y-%m-%d, output as date type.
- Renamed columns to comply with BCO-DMO naming conventions.
- Saved the final file as "1006222_v1_winter_lake_erie_2024_to_2025.csv".
CURATION ACTIONS PERFORMED ON METADATA
- BCO-DMO's standard metadata entry and text formatting steps were performed.
ISSUES POTENTIALLY IMPACTING REUSE
- The time zone is listed as Eastern Daylight Time (EDT), but during the time span of the dataset, local time would have switched to Eastern Standard Time (EST). One might assume EDT was used throughout the dataset, but this has not been confirmed by the data submitter.

2 L Van Dorn water sampler
2 L Van Dorn water sampler
PI Supplied Instrument Name: 2 L Van Dorn water sampler PI Supplied Instrument Description:A Van Dorn water sampler was used to collect water at a depth of 1 meter. Instrument Name: Van Dorn water sampler Instrument Short Name: Instrument Description: A free-flushing water sample bottle comprising a cylinder (polycarbonate, acrylic or PVC) with a stopper at each end. The bottle is closed by means of a messenger from the surface releasing the tension on a latex band and thus pulling the two stoppers firmly into place. A thermometer can be mounted inside the bottle. One or more bottles can be lowered on a line to allow sampling at a single or multiple depth levels. Van Dorn samplers are suitable for for physical (temperature), chemical and biological sampling in shallow to very deep water. Bottles are typically lowered vertically through the water column although a horizontal version is available for sampling near the seabed or at thermoclines or chemoclines. Because of the lack of metal parts the bottles are suitable for trace metal sampling, although the blue polyurethane seal used in the Alpha version may leach mercury. The Beta version uses white ASA plastic seals that do not leach mercury but are less durable.
