Optical Signatures of Climate Change Impacts on Phytoplankton

Explore the optical signatures of climate change impacts on phytoplankton through images showing differences in primary production, reflectance ratios, community changes, and trends in various oceanic regions. The data visualizations provide insights into the effects of climate change on phytoplankton communities and offer a glimpse into potential future scenarios.

1. THE OPTICAL SIGNATURES OF CLIMATE CHANGE IMPACTS ON PHYTOPLANKTON

2. 2000 Difference (2100-2000) 7 2 6 1 5 3 4 5 year averages

3. Amount of pre-industrial community still in any location in year 2100 (1=all community still there, 0=none of community there) New community can have invaded so does not imply decrease in biomass Fk is biomass of each phytoplankton type 5 year averages

4. 2000 Difference (2100-2000) 5 year averages

5. Difference (2100-2000) 5 year averages

6. THE OPTICAL SIGNATURES OF CLIMATE CHANGE IMPACTS ON PHYTOPLANKTON Difference in Primary Production (2100-2000) N Atlantic S Ocean 425/550 450/550 475/550 Difference in Ratio of Reflectance (R(425)/R(550) (2100-2000) N Atlantic S Ocean 5 year averages

7. Fraction of 2000 community remaining in 2100 N Atlantic S Ocean 425/550 450/550 475/550 Difference in Ratio of Reflectance (R(425)/R(550) (2100-2000) N Atlantic S Ocean 5 year averages

8. N Atlantic 425 475 500 550 600 425/550 450/550 475/550 TRANSIENT RUN: BUSINESS AS USUAL CONTROL: PRE-INDUSTRIAL monthly averages

9. S Ocean 425 475 500 550 600 425/550 450/550 475/550 TRANSIENT RUN: BUSINESS AS USUAL CONTROL: PRE-INDUSTRIAL monthly averages

10. Question: - Are there optical signatures of community changes? - How to determine trend statistically : especially for non-linear changes? - Which regions have trends even in the control run?
