4.2.3. Investigations on Seasonal pCO2 Gradients
Our further investigations on thermal and non-thermal control on the
gradients of p CO2 in the BUS however, revealed
that the fluctuations in p CO2 are primarily
controlled by biological effects. This pattern is consistently observed
across all sampled regions and remains consistent irrespective of
seasonal variations. The estimated contributions of temperature and
biological activity in the BUS are presented in Table 1. The ratios of
Δp CO2Temp. /
Δp CO2Bio. are always well below 1, varying
from 0.09 to 0.36, typical of coastal ecosystems that are strongly
controlled by biological productivity (e.g. Cotovicz et al., 2015).

and biological control (T - B) and the ratio of T/B for the coastal and
