| Zusammenfassung |
| Free-ocean CO2 enrichment (FOCE) systems are designed to assess the
impact of ocean acidification on biological communities in situ for extended
periods of time (weeks to months). They overcome some of the drawbacks of
laboratory experiments and field observations by enabling (1) precise
control of CO2 enrichment by monitoring pH as an offset of ambient
pH, (2) consideration of indirect effects such as those mediated through
interspecific relationships and food webs, and (3) relatively long
experiments with intact communities. Bringing perturbation experiments from
the laboratory to the field is, however, extremely challenging. The main goal
of this paper is to provide guidelines on the general design, engineering,
and sensor options required to conduct FOCE experiments. Another goal is to
introduce xFOCE, a community-led initiative to promote awareness, provide
resources for in situ perturbation experiments, and build a user
community. Present and existing FOCE systems are briefly described and
examples of data collected presented. Future developments are also addressed
as it is anticipated that the next generation of FOCE systems will include,
in addition to pH, options for oxygen and/or temperature control. FOCE
systems should become an important experimental approach for projecting the
future response of marine ecosystems to environmental change. |
