Summary: | <p>Marine Isotope Stage 5 deposits have been reported on many tropical Pacific
islands. This paper presents a database compiled through the review of MIS
5e (last interglacial – LIG) coral reef records from islands belonging to
French Polynesia (Anaa, Niau, Makatea, Moruroa, Takapoto, Bora Bora), the
Hawaiian Islands (Oahu, Lanai, Midway Atoll), Tuvalu, Kiribati (Christmas
Island, Tarawa), the Cook Islands (Mangaia, Atiu, Mitiaro, Mauke, Pukapuka,
Rakahanga, Rarotonga), Tonga, Samoa, the Federal States of Micronesia, the
Mariana Islands, the Marshall Islands (Enewetak, Bikini), New Caledonia,
Papua New Guinea, the Solomon Islands, Vanuatu, Fiji and Niue. Studies
reporting other sea-level indicators dated to other Pleistocene
interglacials and Holocene sea-level indicators were not inserted in the
database but are included in this data description paper for completeness.
Overall, about 300 studies concerning Pleistocene and Holocene sea-level
indicators have been reviewed, and finally 163 age data points and 94
relative sea-level (RSL) data points from 38 studies on the MIS 5e have been
inserted in the database. An additional 155 age data points have been reviewed;
i.e. the tropical Pacific islands database contains 318 age data points.
The main sea-level indicators include emerged coral reef terraces, but also
reef units recovered in drill cores from a few islands, thus reflecting the
diversity of tectonic settings and sampling approaches. Future research
should be directed towards better constrained RSL reconstructions, including
more precise chronological data, more accurate elevation measurements and a better refinement of the palaeo-water-depth significance of
coralgal assemblages. The database for tropical Pacific islands is available
