HABSOS (Harmful Algal BloomS Observing System) is a data collection and distribution system for harmful algal bloom (HAB) information in the Gulf of Mexico. The goal of HABSOS is to provide environmental managers, scientists, and the public with a data driven resource for HAB events. Cell counts and environmental information are combined into a single product and distributed using the HABSOS Mapping System. HABSOS strives to provide the most accurate picture of harmful algal bloom location and quantity by using the latest sample data available. This dataset contains data from Texas, Louisiana, Mississippi, Alabama, and Florida, as well as data along the Florida Shelf in the Gulf of Mexico and along the eastern coast of Florida in the North Atlantic Ocean.
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 190,341 records.
2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
The table below shows only published versions of the resource that are publicly accessible.

The Harmful Algal BloomS Observing System (HABSOS) began as a pilot project in 2001 to focus on recent Karenia brevis blooms in the Gulf of Mexico. This project identified a need for a harmful algal bloom observing network. Many individuals from Gulf of Mexico state agencies and universities, US Environmental Protection Agency, and NOAA National Coastal Data Development Center (NCDDC) participated in this project. This product developed a strong partnership between Gulf of Mexico partners and NOAA National Centers for Environmental Information (formerly NCDDC). HABSOS evolved into a database of HAB observations and associated environmental observations submitted by the partners who collect these data. These data are updated annually and made publicly available in the NCEI archive and via the interactive map viewer. NCEI’s HABSOS provides a research quality HAB dataset and HAB observations in near-real time.

marine, harvest by OBIS HAB abundance condition levels in the measurement or fact extension are determined based on the number of cells/L and have associated possible effects as documented here: https://myfwc.com/research/redtide/statewide/. Specifically "Not Present" means 1000 cells or less and no effects anticipated. "Very Low" means cells 1001 - 10,000 and lead to possible respiratory irritation; shellfish harvesting closures when cell abundance equals or exceeds 5000 cells/L. "Low" means cells 10,001 - 100,000 and lead to respiratory irritation; shellfish closures; possible fish kills; probable detection of chlorophyll by satellites at upper range of cell abundance. "Medium" means cells 100,001 - 1,000,000 and lead to respiratory irritation; shellfish harvesting closures; probably fish kills; detection of surface chlorophyll by satellites. "High" means > 1,000,000 cells/L and all of the effects listed for the "Medium" level plus water discoloration.
