Fig. 4: Intra- and interannual variability in giant kelp canopy biomass (in Gg of wet weight) and physiological state estimated from Landsat imagery across the central and southern California region.

From: Senescence-driven solubilization of biomass is the main source of kelp-derived dissolved organic carbon to the coastal ocean

a Monthly estimates of giant kelp canopy biomass between 2001–2023 derived from Landsat 7, 8, and 9 multispectral sensors. Note: 1 Gg = 1000 metric tons. b Percentage of total monthly biomass in a that is senescent (>50 days old). In both panels, interannual variability is shown by the point and line color. A continuous version of this figure is available in the supplemental section (Supplemental fig. 7) in order to see the data by individual years more clearly.
