This collection contains inputs to, and outputs from the NOAA Harmful Algal Bloom (HAB) Experimental Forecast for Lake Erie in the form of bulletin documents and processed satellite imagery in GeoTIFF format, beginning on 2008-09-04 and continuing to 2016-11-01. The HAB Experimental Bulletin was operated by the National Centers for Coastal Ocean Science to develop and produce experimental forecast bulletins for cyanobacteria blooms (blue-green algae) in Lake Erie. The bulletins contain an analysis of the location of cyanobacteria blooms, forecasts of transport, mixing, scum formation and bloom decline based on the analysis of information from data providers. The bulletins are emailed to subscribers twice weekly during an active bloom. Each year, NCEI creates a new accession containing the data collected during the previous 12 months. The experimental bulletin was started in 2008 and became operational in 2017.

This collection contains inputs to, and outputs from the experimental status NOAA Harmful Algal Bloom Operational Forecast System (HAB-OFS) for the Gulf of Mexico in the form of documents, processed satellite imagery in HDF4 format, image files, and Geographic Information System (GIS) files, beginning on 2000-09-21, ending on 2003-12-22. The HAB-OFS is operated by the Center for Operational Oceanographic Products and Services to produce forecast bulletins for harmful algal blooms (HABs) of Karenia brevis (red tide) in the Gulf of Mexico. The bulletins contain an analysis of ocean color satellite imagery, field observations, models, public health reports and buoy data and forecasts of potential HAB transport, intensification and associated respiratory irritation based on the analysis of information from data providers. The bulletins are issued twice weekly during an active HAB and once weekly during a non-HAB period to a list of subscribers.

This collection contains outputs from the NOAA Harmful Algal Bloom Operational Forecast System (HAB-OFS) for the Florida and Texas regions. The Operational HAB-OFS output began in 2004, updated in 2022, and is still in production. The current forecast products include beach-level respiratory irritation forecasts based on the analysis of information from data providers, 8-day composite satellite imagery showing bloom extent, field observations, and a bloom intensification forecast in the form of GeoTIFF and comma-separated files. The forecast products are updated throughout the day as source data becomes available and accessible via the Florida and Texas HAB forecast web pages. The previous version (2004-2021) of the forecast contained an analysis of ocean color satellite imagery, field observations, models, public health reports and buoy data and forecasts of potential HAB transport, intensification and associated respiratory irritation based on the analysis of information from data providers. Prior to 2004, the HAB-OFS output for the Florida and Texas regions were considered to be experimental. This program was operated experimentally from 2000 to 2003. These data are also available at the NCEI archive.

Water quality data was collected by the United States Army Corp of Engineers at numerous locations along the shore of Lake Ponchartrain, Louisiana during the month of September 2019. The samples were collected repeatedly at 8 locations around the lake. The parameters collected include chlorophyll a (uncorrected), chlorophyll b, chlorophyll c1 + c2, phycocyanin, microcystin, water temperature, dissolved oxygen, dissolved oxygen percent saturation, pH, salinity, and specific conductance. These data were used to monitor the water quality of commonly used beaches and swimming areas. These data are in spreadsheet form.

Blooms of nuisance and toxic cyanobacteria, referred to as cyanobacteria harmful algal blooms (cHABs), occur seasonally in Saginaw Bay, Lake Huron, and pose a threat to human health, affect the quality of life, and significantly degrade the ecosystem. NOAA Great Lakes Environmental Research Laboratory and the Cooperative Institute for Great Lakes Research (CIGLR), University of Michigan, started regular water quality monitoring of Saginaw Bay, Lake Huron in 2012. Since that time the monitoring effort has expanded to incorporate additional parameters and sample locations. Physical, chemical, and biological water quality data were collected during repeated sampling trips to a set of stations before, during, and after HAB events (from May - October). Data for these discrete sampling events include: Secchi disk depth, Conductivity, Temperature and Depth (CTD), CTD specific conductivity, CTD beam attenuation, CTD beam transmission, CTD dissolved oxygen, CTD photosynthetically active radiation, turbidity, particulate microcystin, dissolved microcystin, extracted phycocyanin, extracted chlorophyll-a, total phosphorus, total dissolved phosphorus, soluble reactive phosphorus, ammonia, nitrate + nitrite, urea, particulate organic carbon, particulate organic nitrogen, dissolved organic carbon, chromophoric dissolved organic material absorbance at 400 nm, total suspended solids, and volatile suspended solids. The bulk water quality parameters were analyzed via established techniques and procedures for routine water quality monitoring and analysis (APHA 1992, 1998, 2017). This research was funded by the Great Lakes Restoration Initiative (GLRI) to support the projects “Decision Support Tools to Link Predictions to HABs and Source Water Protection”, Synthesis Observation and Response (SOAR), and Real-time Environmental Coastal Observation Network (ReCON).
