Assessing the influence of ocean alkalinity enhancement on a coastal phytoplankton community - manuscript data

The effect of ocean alkalinity enhancement on a coastal phytoplankton community was assessed via a microcosm experiment. The effect of alkalinity enhancement in two scenarios (i) when enclosed seawater was in equilibrium with atmospheric CO2 and (ii) when enclosed seawater was not in equilibrium with atmospheric CO2 were explored. Alkalinity was increased by ~497 umol/kg in these two treatments and plankton communities, carbonate chemistry, dissolved inorganic nutrients, particulate matter and chlorophyll a dynamics monitored over a 22 day period where a spring bloom occurred.

Statement
Sampling involved individually submersing nine open microcosms to a depth of 1 meter below sea level and then closing these microcosms, enclosing seawater and a naturally occurring phytoplankton community. Once the water was enclosed inside the microcosms, they were transported inside (IMAS) split into three groups; a control which received no alkalinity manipulation, “unequilibrated” group enriched with 500 µL of NaOH (Merck, Titripur) per litre, and “equilibrated” group enriched with 423 µL of 1 molar NaHCO3 solution per litre and 77 µL of NaOH (Merck, Titripur) per litre. following this microcosms were left to incubate for 22 days and a range of samples taken from each microcosm on varying timescales dependent on the sample. Samples/measurements taken included; pH, temperature, dissolved inorganic nutrients (nitrate+nitrite, phosphate, silicate), flow cytometry (1-3 ml from each microcosm), total particulate material (carbon, nitrogen and phosphate), chlorophyll a, total alkalinity and samples for the scanning electron microscope.
