Summary
Abstract: This data set consists of 5-Yr interval Flinders Reef Boron Isotope, pH,
Aragonite Saturation State, Carbon Isotope, Extension Rate and Calcification
Data for 1708 to 1988.

The oceans are becoming more acidic due to absorption of anthropogenic carbon
dioxide from the atmosphere. The impact of ocean acidification on marine
ecosystems is unclear, but it will likely depend on species adaptability and
the rate of change of seawater pH relative to its natural variability. To
constrain the natural variability in reef-water pH, we measured boron isotopic
compositions in a ~300-year-old massive Porites coral from the southwestern
Pacific. Large variations in pH are found over ~50-year cycles that covary
with the Interdecadal Pacific Oscillation of ocean-atmosphere anomalies,
suggesting that natural pH cycles can modulate the impact of ocean
acidification on coral reef ecosystems.

A 4.2 m long core of Porites sp. coral was analyzed from Flinders Reef, an
offshore reef on the Queensland Plateau (17.5S, 148.3E), in the Coral Sea, ~250
km from the north-east coast of Australia. The coral core was cut lengthwise
into 7-mm-thick slices and X-rayed to reveal annual density bands, which were
used to establish the coral chronology. Samples were milled in continuous
5-year intervals down the full length of the core along major coral growth axes
for the period 1990 to 1706 AD. More detailed information can be found in the
original reference and in the Supporting Online Material at

Individual boron isotope measurements for the Flinders Reef coral 5-yr interval
dataset and for a section analyzed at high resolution (every mm, corresponding
roughly to monthly resolution from April 1987 to April 1988) are available as
