6-2CoralReefWatch (1)-1.docx - MVS Oceanography 6.2 - Coral Overfishing depletes the number of fish that eat algae and keep the reefs ecosystem in balance. Here we synthesize field observations of coral bleaching at 3351 sites in 81 countries from 1998 to 2017 and use a suite of environmental covariates and temperature metrics to analyze bleaching patterns. Although the tropics may be potentially more stable through climate changes than elsewhere, several modeling studies have nevertheless predicted high species loss near the Equator with increasing temperatures22,23. %PDF-1.4 % Maldives coral reefs under stress from climate change: research - IUCN NOAA_OI_SST_V2 data was provided by the NOAA/OAR/ESRL PSD, Boulder, Colorado, USA, from their Web site at https://www.esrl.noaa.gov/psd/. 3. Corals and Climate | Center for Science Education 4. The results that coral bleaching was less common in the equatorial regions, with high coral diversity19, agree with paleoecological studies that show greatest stability and lowest extinction in the tropics through rapid climate change20. Hoegh-Guldberg, O. Climate Change - National Oceanic and Atmospheric Administration Depth is the depth in meters. The world currently is experiencing the longest global coral bleaching event ever recorded, with the Great Barrier Reef and U.S. reefs among those suffering. 515). Article For example, in biology, the CXLS acts like an ultrafast camera to see proteins and other building blocks of biology dynamically at work, analogous to how the very first X-rays yielded new views of our bodies. If so, inshore corals and algae should bleach less often than offshore corals and algae.
