We can still protect and preserve the remaining reefs, and NOAA is leading U.S. efforts to study and conserve these precious resources for future generations. How does NOAA’s fleet of satellites take part in this effort?
NOAA Satellites Monitor Sea Surface Temperature
Satellites provide a critical component of sea temperature monitoring. This data can help long and short-term marine ecosystem conservation efforts by alerting scientists and researchers to the potential for coral bleaching events.
NOAA’s satellites are able to quickly and efficiently capture ocean temperatures around the globe. Satellite remote sensing provides a near real-time global view of the oceans and monitor previously inaccessible remote reefs.
Satellites capture temperature data by detecting radiation microwave wavelengths of light emitting from the ocean. The variation in amplitude of these wavelengths is an accurate measure of ocean temperature. NOAA’s GOES-16 satellite uses its I-M imager and NOAA-20 will use its Visible Infrared Imaging Radiometer Suite (VIIRS) technology to capture this data. The data enables scientists and forecasters to monitor and predict weather patterns with greater accuracy and to study long-term climate trends. Check out this near real-time data available HERE.
The Coral Reef Watch effort uses a blend of NOAA’s geostationary and polar orbiting satellite data to analyze sea surface temperature. This provides a 100-fold improvement in spatial resolution over earlier products. The new blended sea surface temperature products also help to reduce missing data caused by cloud coverage over the oceans. This is particularly vital in areas such as the “Coral Triangle,” which consists of the tropical marine waters of Indonesia, Malaysia, Papua New Guinea, Philippines, Solomon Islands and Timor-Leste that have months of persistent cloud cover some years.
Coral Reef Watch is supported by NOAA’s Coral Reef Conservation Program. The program delivers sound scientific information and tools that decision-makers and communities need to effectively address the primary threats facing coral reef ecosystems.
What Can You Do To Help?
- Everyone can help protect coral reefs, here’s how!
- Don't buy corals or give them as presents.
- Conserve water. The less water you use, the less runoff and wastewater that will eventually find its way back into the ocean.
- Volunteer in local beach or reef cleanups. If you don't live near the coast, get involved in protecting your watershed.
- Become an informed consumer and learn how your daily choices like water use, recycling, seafood, vacation spots, fertilizer use, and driving times can positively (or negatively) impact the health of coral reefs.
Visitors to coral reef and coastal areas have an especially important role in protecting these vulnerable areas. Hiring a local guide to support the economy, picking up any trash, never touching or harassing wildlife in reef areas and avoiding dropping your boat anchor or chain nearby a coral reef - are all helpful.
Finally, stay informed and spread the word! Educate yourself about why healthy coral reefs are valuable to the people, fish, plants, and animals that depend on them.
