The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Dissolved inorganic carbon, total alkalinity, dissolved oxygen, and pH monitored from benthic Free Ocean Carbon Enrichment (FOCE) -type study in Heron Island reef flat (NODC Accession 0113856) |
| Abstract: | Ocean acidification poses multiple challenges for coral reefs on molecular to ecological scales, yet previous experimental studies of the impact of projected CO2 concentrations have mostly been done in aquarium systems with corals removed from their natural ecosystem and placed under artificial light and seawater conditions. The Coral-Proto Free Ocean Carbon Enrichment System (CP-FOCE) uses a network of sensors to monitor conditions within each flume and maintain experimental pH as an offset from environmental pH using feedback control on the injection of low pH seawater. Carbonate chemistry conditions maintained in the -0.06 and -0.22 pH offset treatments were significantly different than environmental conditions. The results from this short-term experiment suggest that the CP-FOCE is an important new experimental system to study in situ impacts of ocean acidification on coral reef ecosystems. |

| Supplementary information: | The Free Ocean Carbon Enrichment (FOCE) is an in-situ experimental system where future predicted pH levels as an offset below what is measured in the environment can be produced. The -0.2 FOCE refers to the chamber in which a medium level offset (around -.15 pH units) was produced, and the -0.4 FOCE is the more extreme treatment where it was around a -0.3 pH offset below the environment. pH values in the data file use a pH scale of "Total pH Scale".
