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.

THE OPTICAL SIGNATURES OF CLIMATE CHANGE IMPACTS ON PHYTOPLANKTON
2000 Difference (2100-2000) 7 2 6 1 5 3 4 5 year averages
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
2000 Difference (2100-2000) 5 year averages
Difference (2100-2000) 5 year averages

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?
