The record of ice-sheet demise since the last glacial maximum (LGM) provides an opportunity to test the relative importance of instability mechanisms, including relative sea-level (RSL) change, controlling ice-sheet retreat. Here we examine the recor... Read More about Investigating the roles of relative sea-level change and glacio-isostatic adjustment on the retreat of a marine based ice stream in NW Scotland.

Local and Regional Constraints on Relative Sea-Level Changes in Southern Isle of Skye, Scotland, since the Last Glacial Maximum (2021)
Journal Article

New relative sea-level (RSL) data constrain the timing and magnitude of RSL changes in the southern Isle of Skye following the Last Glacial Maximum (LGM). We identify a marine limit at ~23 m OD, indicating RSL ~20 m above present c. 15.1 ka. Isolatio...

Assessing the use of mangrove pollen as a quantitative sea‐level indicator on Mahé, Seychelles (2021)
Journal Article
Sefton, J., & Woodroffe, S. (2021). Assessing the use of mangrove pollen as a quantitative sea‐level indicator on Mahé, Seychelles. Journal of Quaternary Science, 36(2), 311-323. https://doi.org/10.1002/jqs.3272

We investigated the potential of mangrove pollen from Mahé, Seychelles, to improve existing metre‐scale Late Holocene sediment‐based sea‐level reconstructions. Mangrove species at two mangrove sites are broadly zoned according to elevation within the...

Mid- to late Pliocene (3.3–2.6 Ma) global sea-level fluctuations recorded on a continental shelf transect, Whanganui Basin, New Zealand (2018)
Journal Article
Grant, G., Sefton, J., Patterson, M., Naish, T., Dunbar, G., Hayward, B., …Turner, G. (2018). Mid- to late Pliocene (3.3–2.6 Ma) global sea-level fluctuations recorded on a continental shelf transect, Whanganui Basin, New Zealand. Quaternary Science Reviews, 201, 241-260. https://doi.org/10.1016/j.quascirev.2018.09.044

We present a ∼900 m-thick, mid- (3.3–3.0 Ma) to late Pliocene (3.0–2.6 Ma), shallow-marine, cyclical sedimentary succession from Whanganui Basin, New Zealand that identifies paleobathymetric changes, during a warmer-than-present interval of Earth his...
