Investigation of the influence of modified sediment on pH using rapid pH assessment methods
Ocean acidification is changing the chemistry of the ocean and has the potential to result in large-scale ecosystem changes. Observations of dissolved shells and low survivorship rates of juvenile bivalves are a concern for the aquaculture industry. This research conducted in Baynes Sound, assessed...
