“…Britain is reasonably well understood (Bradley et al, 2011;Smith et al, 2012). The RSL fall in north 115 west Scotland is in contrast to other late Holocene RSL records in the North Atlantic from coastlines 116 that are isostatically subsiding.…”

“…Later isobase models (e.g. Smith et al ., ) have become more statistical in nature and applied trend‐surface analyses to shorelines that are essentially time‐transgressive. The maps of ongoing relative sea‐ (or land‐) level changes by Shennan and Horton () and Shennan et al .…”

In this paper we identify four 'revolutions' that in our view have shaped the study of sea-level changes in recent decades. (i) The search for 'eustasy'. One of the most hotly debated issues in the 1960s is still relevant as models of glacial isostatic adjustment (GIA) require input of the amount of meltwater transferred to the world's oceans following the demise of the large Pleistocene ice sheets. (ii) Resolution of sea-level archives. All sea-level archives have limitations in their resolving power but are we willing to define these? From studies of saltmarsh deposits and corals it is highly likely that climate-driven metre-scale sea-level fluctuations have not occurred during the middle and late Holocene. (iii) Rapid sea-level changes. Improved coring technology has resulted in the suggestion of meltwater pulses during the last deglaciation. Low-frequency high-magnitude events have been documented along seismically active shorelines and provide information on seismic hazards and storm impacts. (iv) Merging of empirical sea-level investigations and models. Much sea-level research in the past two decades has embraced the integration of models and field-derived data, providing testable hypotheses and insights into processes. We conclude with some reminders about the 'inconvenient truths' that keep the sea-level scientist honest.

“…On the one hand, geological evidence from palaeoshorelines and undisturbed isolation basins has been used to reconstruct long-term Holocene RSL change [5,6]. This information derived from sea-level index points has been employed to inform empirical isobase models of the uplift in Scotland using trend surface analyses [7,8], as well as to calibrate theoretical GIA models that rely on Earth mantle rheology and ice-sheet history [2,[9][10][11][12]. The latter approach faces a common modelling problem, namely a trade-off between Earth mantle parameters that leads to non-uniqueness of the solutions [13,14].…”

Understanding the effects of glacial isostatic adjustment (GIA) is essential for the assessment of past and future sea-level trends. This study examines the applicability of Small Baseline InSAR to measure GIA-induced vertical land movement in Northern Britain. Different SAR sensors are utilized to cover a time frame of about 20 years. The aim is to establish the spatial distribution of GIA along the coast and uplift centre of Scotland in greater detail compared to results from conventional geodetic techniques, which are interpolated from point measurements. A range of possible error sources within the InSAR processing chain, that lead to orbital and atmospheric artefacts, require to be addressed in order to allow the extraction of any GIA deformation signal. Continuous GPS (CGPS) station coordinates thus need to be integrated with the InSAR data.
