Current Sanctuary Conditions
Wind, Waves, and Water Temperatures
You can get an idea of current sanctuary conditions by looking at real-time data from the Sofar Spotter buoy installed at East Flower Garden Bank in June 2023. This buoy collects wave height and wind speed data, as well as temperatures from the surface and at reef cap depth, providing important information for both staff and visitors to assess current offshore conditions.
Installation of this buoy was supported by the National Marine Sanctuary Foundation and Dr. Xinping Hu from Texas A&M University - Corpus Christi.
Chlorophyll-a, Sea Surface Temperature, Suspended Sediment, Algal Bloom Index, and More
Additional remote sensing data for the northwestern Gulf of Mexico is available via satellites and data buoys outside the sanctuary. This has been compiled into a handy dashboard where users can focus in on individual banks within the sanctuary, as well as identified zones between the sanctuary and the Texas and Louisiana coastlines.
In addition to current conditions, this dashboard shows time-series data from the previous two years.
Texas Automated Buoy System
The Texas Automated Buoy System (TABS) funded two buoys in the vicinity of the Flower Garden Banks, TABS Buoy N and TABS Buoy V, until 2017 and 2019 respectively. Historic data from those buoys is still available on the TABS website. The Sofar Spotter buoy, installed in 2023, fills the data void left by the loss of the TABS buoys.
There are still three functioning TABS buoys closer inshore, buoys B, F, and R, that may be of some help to visitors heading out to the sanctuary.
