Fig. 4: Time series of seasonal phytoplankton composition in NESAP waters.
From: Marine heatwaves modulate food webs and carbon transport processes
Phytoplankton groups were estimated using CHEMTAX analysis of pigment concentrations measured using HPLC. A Average concentrations of major phytoplankton groups from hydrographic stations along the Line P transect (P20-P26). B Average relative concentrations of major phytoplankton groups across P20-P26. Wi winter, Sp spring, Su summer. C Principal components analysis (PCA) ordination biplot of phytoplankton group abundance, with points color-coded by year and shapes by season. Directions and length of vectors indicate how each phytoplankton group contributes to the annual and interannual variation in phytoplankton community composition in this region. Note that MHW years (2015 and 2019) are indicated by shades of red.
