Harmful Algae Bloom Data

Cell Count Map Screenshot

Cyanobacteria

Water quality data was collected by the United States Army Corps of Engineers at numerous locations along the shore of Lake Ponchartrain, Louisiana during the month of September 2019. 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.

 

Florida

Florida's cell counts are reported by a network of monitoring entities. These entities include: Florida Fish and Wildlife Research Institute (FWRI), Mote Marine Laboratory (MML), Sarasota County Health Department (SCHD), and Collier County Pollution Control and Prevention Department (CCPCPD).

 

Texas

The Texas Parks and Wildlife Department (TPWD) is the lead agency involved in Texas marine harmful algal blooms. All of the cell counts within Texas boundaries are collected and reported by TPWD.

 

Mississippi

The Mississippi Department of Marine Resources (MDMR) collects phytoplankton samples for routine analysis of oyster growing waters open to harvest and responsive (emergency) samples. During routine sampling, staff collect 1 sample each month from open oyster growing areas within the MS Sound.  An in-house qualitative analysis is conducted and if a toxic bloom is present, a quantitative analysis will be conducted.  The cell count data from the quantitative analysis will be reported. Responsive sampling occurs when the MDMR receives a report of a bloom from a credible source. In addition, field technicians are trained to make observations while collecting fisheries samples throughout the week.

 

Alabama

Alabama has about 100 miles of coastline along the Gulf of Mexico and Mobile Bay. The Alabama Department of Public Health -Seafood Branch (ADPH) in collaboration with Alabama Department of Environmental Management (ADEM) collects and monitors for Harmful Algal Bloom (HAB) species under the regulation and guidance of the FDA. Toxic HAB species of concern in Alabama waters are: Karenia brevis, Dinophysis and Pseudo-nitzschia.

In-Situ Measurements
 

Weather Radar

The National Weather Service (NWS) creates a base reflectivity image from a network of Doppler radars. This image is updated hourly and can be used to monitor current precipitation.
 

Weather Observations

Compilation of weather stations from both marine and land.  These stations report observed conditions from the previous 3 hours. Marine stations may report additional oceanographic data such as wave height.  
 

 


Models
 

Aerosol Observation Forecast

The Aerosol Observation Forecast layer are images downloaded from the US Global Ocean Data Assimilation Experiment (USGODAE). The images are generated by the Naval Research Laboratory, Monteray, CA, from data representing the concentration of aerosols such as smoke or dust. A common source of these are wildfires, wind transport from the Saharan Desert, among other sources (more information).
 

NWS Air Temperature

The National Digital Forecast Database (NDFD) contains a seamless mosaic of the National Weather Service's (NWS) digital forecasts of air temperature. In collaboration with NWS National Centers for Environmental Prediction (NCEP) and NWS Weather Forecast Offices (WFO), the central NDFD server ingests 5-km, 2-dimensional grids of air temperature, and creates experimental forecast data mosaics for the coterminous United States (CONUS), Alaska, Hawaii, and Guam. These data are updated daily on the HABSOS page to get the 24, 48, and 72 hour forecasts for air temperatures.

Wind Speeds (Forecasts)

The NOAA National Weather Service's (NWS) Environmental Modeling Center (EMC) generates meteorological forecasts from the NAM computer model on a 6-hour cycle, daily. Each cycle provides forecasts from zero hours out to 84 hours and provides predictions for a number of different variables including wind speed and direction. This data set was created by extracting surface wind speed and direction values for a defined geographic region from the NAM-12 data made available by the EMC on an FTP server. These data are updated daily on the HABSOS page to retrieve the 0, 12, 24, 36, 48, and 72 hour forecasts.

U.S. River Streamflow

The USGS maintains a network of streamflow stations throughout the United States and its territories. This layer shows the current stage/status of each of the USGS stream gauges. 

 

Bathymetry

This layer provides bathymetric contours with increasing resolution in coastal areas. Sets of contours were generated at 100, 200, 1000, 2000, 3000, 4000, 5000, and 6000 meter depths.

 

Estuarine Reserves

The National Estuarine Research Reserve System (NERRS) seeks to preserve unique coastal habitats for long-term research, water-quality monitoring, education and coastal stewardship. The sites are managed through a partnership between NOAA and local state government.

The five Gulf Coast reserve sites are all excellent sources for up-to-date and long-term monitoring data.

 

Marine Sanctuaries

The National Marine Sanctuary System (NMSS) seeks to protect critical habitats, unique environments, and sites of historical significance. The Gulf Coast hosts two marine sanctuaries, the Florida Keys and the Flower Garden Banks.

 

Eastern Oyster Reefs

The Eastern Oyster feeds on single celled marine phytoplankton. During a harmful algal bloom, oysters can become toxic with the accumulated toxins of the harmful algae. These data display oyster reefs that have been mapped.
