Seasonal Variation in Shell Calcification of Planktonic Foraminifera in the NE Atlantic Reveals Species-Specific Response to Temperature, Productivity, and Optimum Growth Conditions
Fig 11
Interaction plot of the calcification intensity in Globigerinoides ruber (white) and Globigerinoides elongatus sampled from March 2002 until April 2003 with sediment trap L1/K276.
While both species generally show a positive correlation of area density with sea surface temperature (SST) and a negative correlation with surface water productivity, the variable offset between the lines shows that both species differ in base calcification intensity and react differently to changes in the environment (compare Table 4).
