This article reviews key data and debates focused on relative sea-level changes since the Last Interglacial (approximately last 132,000 years) in Mediterranean Basin, their implications for past human populations. Geological geomorphological landscape studies are critical to archaeology. Coastal regions provide a wide range of resources populations that inhabit them. landscapes increasingly focus scholarly discussions from earliest exploitation littoral early hominin cognition, inundation permanently settled fishing villages eventually, formative centres urbanisation. In Mediterranean, these would become hubs maritime transportation gave rise roots modern seaborne trade. As such, this represents an original review both geo-scientific archaeological specifically relate resulting impacts physical cultural Palaeolithic until emergence Classical periods. Our highlights interdisciplinary links between coastal archaeology, geomorphology important explain environmental societies migration. We geological indicators sea level outline how features commonly used as proxies measuring levels, gradual catastrophic events. argue archaeologists should, part analyses, incorporate concepts, such indicative meaning. The interpretation meaning Roman fishtanks, example, plays role reconstructions late Holocene levels. identify avenues future work, which include consideration glacial isostatic adjustment (GIA) addition tectonics vertical movements coastlines, more research island colonisation, broadening materials entire not just resources, rescue sites under threat by change, expansion underwater explorations combination with submarine geomorphology. presents collaborative synthesis data, some have been collected analysed authors, MEDFLOOD (MEDiterranean change projection FLOODing) community, sites, concepts ongoing debates.

Abstract The evolution of past global ice sheets is highly uncertain. One example the missing problem during Last Glacial Maximum (LGM, 26 000-19 000 years before present) – an apparent 8-28 m discrepancy between far-field sea level indicators and modelled from sheet reconstructions. In absence reconstructions, researchers often use marine δ 18 O proxy records to infer volume prior LGM. We present a reconstruction for 80 years, called PaleoMIST 1.0, constructed independently records. Our compatible with LGM sea-level without requiring extra volume, thus solving problem. However, Marine Isotope Stage 3 (57 000-29 - pre-LGM period our does not match proxy-based indicating relationship may be more complex than assumed.

Determining the rates, mechanisms, and geographic variability of relative sea-level (RSL) change following Last Glacial Maximum (LGM) provides insight into sensitivity ice sheets to climate change, response solid Earth gravity field ice-mass redistribution, constrains statistical physical models used project future rise. To do so in a scientifically robust way requires standardized datasets that enable broad spatial comparisons minimize bias. As part larger goal develop unified, spatially-comprehensive post-LGM global RSL database, this special issue we provide synthesis regional data resulted from first ‘Geographic HOLocene SEA level (HOLSEA)’ meetings Mt Hood, Oregon (2016) St Lucia, South Africa (2017). The HOLSEA brought together researchers agree upon consistent protocol standardize, interpret, incorporate realistic uncertainties data.

Future sea-level rise generates hazards for coastal populations, economies, infrastructure, and ecosystems around the world. The projection of future relies on an accurate understanding mechanisms driving its complex spatio-temporal evolution, which must be founded history. We review current methodologies data sources used to reconstruct history change over geological (Pliocene, Last Interglacial, Holocene) instrumental (tide-gauge satellite alimetry) eras, tools project spatial temporal evolution sea level. summarize level near (through 2050), medium (2100), long (post-2100) terms. Using case studies from Singapore New Jersey, we illustrate ways in can constrain projections, how projections motivate development new research questions across relevant timescales.

Significance The seas are rising as the planet warms, and reconstructions of past sea level provide critical insight into sensitivity ice sheets to warmer temperatures. Past is reconstructed from geologic record by measuring elevations fossilized marine sediments coral reefs. However, these features also local uplift or subsidence due growth decay since time deposition. We compare observations paleo across Bahamian archipelago with a range Earth deformation models revise estimates last interglacial global mean level. Our results suggest that polar may be less sensitive high-latitude warming than previously thought.

Rates of relative sea-level rise during the final stage last deglaciation, early Holocene, are key to understanding future ice melt and change under a warming climate1. Data about these rates scarce2, this limits insight into contributions North American Antarctic sheets global Holocene. Here we present an Holocene curve based on 88 data points (13.7-6.2 thousand years ago (ka)) from Sea (Doggerland3,4). After removing pattern regional glacial isostatic adjustment caused by melting Eurasian Ice Sheet, residual signal highlights two phases accelerated rise. Meltwater sourced drove phases, peaking around 10.3 ka 8.3 with between 8 mm yr-1 9 yr-1. Our results also show that mean 11 3 amounted 37.7 m (2σ range, 29.3-42.2 m), reconciling mismatch existed estimates ice-sheet reconstructions previously limited data. With its broad spatiotemporal coverage, dataset provides critical constraints patterns late-stage deglaciation sheets, improving our Earth-system response climate change.

Abstract. Glacial isostatic adjustment (GIA) describes the response of solid Earth, gravitational field, and oceans to growth decay global ice sheets. A commonly studied component GIA is “postglacial rebound”, which specifically relates uplift land surface following melt. a relatively rapid process, triggering 100 m scale changes in sea level Earth deformation over just few tens thousands years. Indeed, first-order effects could already be quantified several hundred years ago without reliance on precise measurement techniques scientists have been developing unifying theory for observations 200 Progress towards this goal required number significant breakthroughs made, including recognition that sheets were once more extensive, shape time, gravity plays central role determining pattern sea-level change. This article historical development field provides an overview processes involved. Significant recent progress has made as concepts associated with begun incorporated into parallel fields research; these advances are discussed, along likely play addressing outstanding research questions within system modelling.

Estimating minimum ice volume during the last interglacial based on local sea-level indicators requires that these are corrected for processes alter sea level relative to global average. Although glacial isostatic adjustment is generally accounted for, scale dynamic changes in topography driven by convective mantle flow not considered. We use numerical models of quantify vertical deflections caused and compare predictions at passive margins a globally distributed set markers. The predicted as result significantly correlated with marker elevations (>95% probability) consistent construction preservation attributes across types. conclude signal present elevation records must be any effort determine peak mean within an accuracy several meters.
