dc.description.abstract | Ocean acidification has critical impacts on marine ecosystems, but presents
knowledge gaps on the ecological impacts requiring large-scale monitoring of
physicochemical conditions to predict biological responses to ocean pH
projections. The threat is especially significant in coastal regions like
upwelling areas which are more sensitive and appear to respond more
rapidly to anthropogenic perturbations. These ecosystems, such as the
northwest coast of the Iberian Peninsula are characterized by complex
physical and biogeochemical interactions, supporting enormous biological
productivity and productive fisheries. The distribution of pH in upwelling
systems has high variability on short temporal and spatial scales preventing a
complete picture of acidification, which exhibit long-term pH rates markedly
different from the measured in open waters. This motivation to significantly
expand the coverage of pH monitoring in coastal areas has driven us to develop
an autonomous pH monitoring instrument (from now on SURCOM) based on
the Honeywell Durafet® pH electrode. A relevant feature is that SURCOM
transmits near real-time pH and temperature measurements every 10.5 min
through SIGFOX®, a low-power, low-bandwidth network for data transmission.
This very careful design allows us to achieve a very low power consumption for
the complete system resulting in 3 years of full autonomy with no other need
than external cleaning and calibration. In this paper we describe the setup and
the data set obtained by a SURCOM instrument over 240 days in a highly
productive and dynamic coastal ecosystem, the Rıá de Arousa embayment,
providing valuable information on the performance of these low-cost and
highly stable sensors, with potential for improving the pH variability description
in nearshore systems and for reinforcing the monitoring-modeling of
coastal acidification. | en_US |
