attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv,.esriCsv,.geoJson,.odvTxt
attribute NC_GLOBAL acquisition_description String Sampling and sample processing followed Salk et al., (2018).

Briefly, at each sampling location, water column physical and chemical
parameters (pH, conductivity, temperature, dissolved oxygen) were measured
using a YSI 600QS sonde (YSI Inc., Yellow Springs, OH, USA). Water samples
were collected by Van Dorn bottle at 1m depth for the analysis of NO3, NH4,
phosphate, TKN, TP, chl a concentrations, total microcystins and cell
identification/biovolume enumeration. Samples for dissolved nutrient analysis
were filtered immediately upon collection (0.2 um), kept on ice, and frozen
upon return to the lab. Unfiltered sample water was collected for TKN and TP
analysis and also frozen. Total and dissolved (<0.2 um) nutrient
concentrations were determined following analysis of samples at the Ohio State
University Stone Laboratory (Gibralter Island, OH, USA). Samples for chl a
analysis were concentrated on GFC filters whereas raw water samples for
microcystins were frozen in new polycarbonate bottles with subsequent analysis
of both parameters by Ohio EPA.

attribute NC_GLOBAL instruments_1_dataset_instrument_nid String 814600
attribute NC_GLOBAL instruments_1_description String 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.

attribute NC_GLOBAL projects_0_acronym String Great Lakes Center
attribute NC_GLOBAL projects_0_description String NSF Award Abstract:
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.
The Center is jointly supported by NSF and by the National Institute for Environmental Health Sciences (NIEHS).
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.
