Calcium carbonate alters the functional response of coastal sediments to eutrophication-induced acidification

Sediment sampling and flux measurement : Cores were used to collect sediments for analysis of sediment characteristics and macrofauna abundance and richness. Benthic incubation chambers were used to measure solute fluxes across the sediment-seawater interface. Credit We at TERN acknowledge the Tradi...

Description
Summary:Sediment sampling and flux measurement : Cores were used to collect sediments for analysis of sediment characteristics and macrofauna abundance and richness. Benthic incubation chambers were used to measure solute fluxes across the sediment-seawater interface. Credit We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging. Purpose A side-effect of eutrophication is the localised acidification of estuarine sediments, as the microbial respiration of excess quantities of organic matter results in increases in dissolved carbon dioxide. Such acidification can alter benthic ecosystem functions, therefore calcium carbonate was added to sediments to see whether the effects of eutrophication-induced acidification on function could be reduced via the buffering of pH by calcium carbonate dissolution. Progress Code: completed Maintenance and Update Frequency: notPlanned The data set contains information on: sediment characteristics, univariate indices of the macrofauna community and ecosystem functions (net primary production, sediment oxygen consumption and nutrient cycling).
