In both sampling sites the water column was stratified with a thermocline
between 20 and 40 m in which the temperature dropped
from26 °C to 14 °C (Fig. 2). Surface chlorophyll-a values ranged from
0.06 to 0.15 mg m−3 in Sóller and from 0.03 to 0.10 mg m−3 in
Cabrera, the deep chlorophyll maximum (DCM) was at 50–70 m
depth with values between 0.20 and 0.50 mg m−3 in Sóller, and in Cabrera the DCM was between 60 and 80 m with values between 0.21
and 0.27 mg m−3.
