Remote sensing helps scientists monitor coral reefs.  Various parameters can be measured including temperature, turbidity, chorophyll a, wave height and ocean currents.  By monitoring these levels over time, predictions can be made on threats to reef areas like coral stress and coral bleaching.  

NOAA CORAL REEF WATCH

NOAA has several virtual products that help predict levels of stress and coral bleaching.

EXPERIMENTAL PRODUCTS

Coral Bleaching Thermal Stress 90%
  • The area in Belize is under a Watch for the period Jun - Sep 2016.  
  • This product is updated every 2 weeks







Bleaching Alert Levels
  • Available for each virtual site. 
  • There is one in southern Belize at Glover's Atoll and one in Chinchorro Atoll, in southern Mexico.
  • In previous years biologists have noticed differences in bleaching levels between northern and southern Belize so both sites are monitored.

NASA Worldview

NASA Worldview is a product that provides a recent image of the Earth. Useful for monitoring turbidity along coastlines, or cloudcover.

Imagery from Oct 5, 2014 confirms area of turbidity along the Belize Barrier Reef between St George's Caye and Goff's Caye.

MODIS - Moderate Resolution Imaging Spectroradiometer

Satellites measure the color of the ocean to determine the amount of chlorophyll present. The ocean color is often blue, but the satellite can detect very small changes in the ocean color as a result of the chlorophyll in phytoplankton. Yellow and red colors represent higher chlorophyll, and dark blue colors represent lower chlorophyll measurements.   Satellite measurements need to be compared to field measurements to calibrate the satellite measurements.*

The product is also available in Google Earth.
The University of South Florida compiles MODIS (Moderate Resolution Imaging Spectroradiometer) products for Belize.  These satellite images can be compared to ground truthed data and personal observations, and to the imagery available in NASA Worldview above. The maps are not 100% accurate but do provide information on a large scale.

In Google Earth you can zoom in and observe the extent of distribution of chorophyl a.
