Far-field islands in the mid-Pacific provide important data to constrain ice-equivalent sea-level changes and glacial isostatic adjustment models. I standardised published data from five island groups in the mid-Pacific following the HOLSEA database protocol: the Cook Islands, Fiji, Tuamotu (French Polynesia), Gilbert Islands (Kiribati) and Christmas (Kiritimati) Island.
Holocene relative sea-level changes from coral microatolls in Singapore
Coral microatolls have concentric rings that track changes in relative sea level over time. I produced a high-resolution record of Late Holocene relatives sea-level changes from fossil coral microatolls at Sentosa, Singapore. Work is ongoing to model the drivers of relative sea-level change within the region.

Paleo relative sea level and carbon storage of mangrove peat in Belize
In unique locations around the world, thick sequences of mangrove peat have accumulated over the Holocene, preserving a continuous record of post-glacial relative sea-level rise. I produced a high-resolution chronology and sediment accumulation history for mangrove peat in Belize. Work is ongoing to quantify the amount of irrecoverable carbon that exists beneath the mangroves of Belize. We also produced a continuous record of Holocene relatives sea-level changes from the mangrove peat sequence.
