Monthly composite satellite images of sea surface temperature and chlorophyll.
How to use this page to learn about algal blooms
- Move your mouse cursor over the map on the left to see a zoomed in view of the sea surface temperatures (SST).
- Use the color scale on the right of the SST map to find the SST (°C) for the area in the 'zoom box' (red = high, blue = low).
- Move your mouse to the map on the right side to see a zoomed in view of the chlorophyll (indicating algae that may be causing HABs).
- Use the color scale on the right side of the Chlorophyll map to find the Chlorophyll surface concentration (mg/m^3) calculated from Chlorophyll fluorescence values.
- Compare the same area on both maps to see if there is any connection between SST (high or low) and chlorophyll.
- Click top links to view maps at different time-scales.
- The '8-day composite with Surface Currents' top link shows a map of 8-day averaged SST with HF Radar surface current
vectors from the last 25 hrs overlayed on top to show potential relationships between currents and SST or algae.
