information
Multiple Harmful Algae Bloom (HAB) (K. brevis) data sets were obtained for this data layer, including Harmful Algal BloomS Observing System data (HABSOS) from NCEI (1953-2018) and the NOAA HAB Operational Forecast System Dataset (2007-2018). Data includes samples from Texas Parks and Wildlife Department (TPWD) the Louisiana Department of Health and Hospitals, Florida Fish and Wildlife Conservation Commission, Florida Fish and Wildlife Research Institute (FWRI), and the HAB Monitoring Database. Data were combined and reviewed for erroneous entries. Duplicate data from the resulting database were deleted, leaving a total of 155,307 observations. For the purpose of this K. brevis layer, only data from 2000-2018 were used due to sampling biases. An 8 square kilometer hexagonal grid was created covering the Gulf of Mexico and eastern Florida. Each year between 2000-2018 was evaluated separately. If a grid cell contained an observation that registered a value of over 100,000 cells/L (the lethal toxicity level for finfish), the grid cell received a value of '1‘. All other grid cells received a value of '0’ to represent observations below the lethal level of concern to fish. After all years were evaluated, the values for each year were totaled to obtain a resulting frequency value for that grid cell, representing the number of years that grid cell had values greater than or equal to 100,000 cells/L for the years 2000-2018.

dataset
Accuracy
The attributes in this dataset are believed to be accurate.
Horizontal Positional Accuracy
Maximum scale of intended use is 1:80,000.
Completeness Report
Spatial and attribute properties are believed to be complete, although attribute information has been simplified. Geometric thresholds from original data are preserved. No tests have been completed for exhaustiveness.
Conceptual Consistency
These data are believed to be logically consistent. Geometry is topologically clean.
(1) Downloaded HABSOS data from National Centers for Environmental Information (NCEI) and imported the CSV to a shapefile in ArcGIS.
(2) Merged these data with data provided by Karen Kavanaugh (Karen.Kavanaugh@noaa.gov) of NOAA CO-OPS (including Louisiana Dept of Health and Hospitals and Texas Parks & Wildlife Department) and data provided by the Florida Fish and Wildlife Commission (FWRI). Data were requested from FWRI by emailing HABdata@MyFWC.com.
(3) Data were QA/QC'ed and attributes were re-worked to fit with all of the data provided. For example, the data were re-categorized so the HABs categories ('Category' attribute) all matched the HABSOS categorization scheme. Additionally, all absent or not present data observations were categorized as 'Not Present'.
(4) Some errors were found in provided data sets, and follow-up conversations were conducted with data contacts through all data sources. For the HABSOS dataset, we contacted NCEI and were put in touch with the data point-of-contact for the dataset (NCEI Accession 0120767). The errors found in the HABSOS dataset were fixed and the corrected and updated data are now archived with NCEI.
(5) Additional attributes were added for ease of data analysis. For example, the 'Presence' binary attribute was added in order to easily indicate presence or absence of K. brevis.
(6) Data duplicates were removed by using ArcGIS tools to identify and delete duplicates based on the following attributes: Sample Date, Sample Depth, Cell Count, Latitude, and Longitude.
(7) The data were clipped to 1/4 mile inland due to confidence of the data and the lack of relevance to freshwater systems.
(8) Clipped out only years 2000-2018 for data analysis (“HABS_2000_2018” data layer) after looking at sampling distribution from 1954 to 2018. Sampling was irregularly conducted until about 2000, so for the sake of analysis we used the 2000 to 2018 temporal period as more regular sampling was occurring. The final point data set was complete.
(9) Lastly, an 8 square kilometer hexagonal grid was created covering the Gulf of Mexico and eastern Florida. Each year between 2000-2018 was evaluated separately, and if a grid cell contained an observation that registered a value of over 100,000 cells/L (the lethal toxicity level for finfish) then that grid cell obtained a value of '1‘. All other grid cells received a value of '0’ to represent observations below the lethal level of concern to fish. After all years were evaluated, the values for each year were totaled to obtain a resulting frequency value for that grid cell, representing the number of years that grid cell had values ≥100,000 cells/L for the years 2000-2018. This layer indicates the frequency of K. brevis blooms in each 8 square kilometer area over time.
