The Last Interglacial (125 ka) was the most recent period in Earth’s history when global temperatures were approximately 1°C higher than pre-industrial levels, with polar regions experiencing a warming of 3–5°C. This warmer climate led to smaller ice sheets, sea and significant shifts atmospheric oceanic patterns, including changes temperature seasonality. Such likely influenced coastal dynamics, altering prevailing winds, wave regimes, ecosystems like...
North of Haiti, oblique convergence occurs between the Caribbean plate and Bahamas carbonate banks which belong to American plate. In this zone, motion is accommodated by: (1) EW-trending Hispaniola reverse Fault Zone (NHFZ), (2) a NE-trending transpressional domain across (3) two sinistral transform faults Septentrional Oriente (SOFZ) Enriquillo-Plantain Garden (EPGFZ)  located north south country, respectively. This study focuses on emerged sequences marine terraces Haiti...
Coastal landforms constitute a worldwide archive that intricately records past sea-level, morphotectonics and (bio-)morphogenesis. Although forward landscape evolution modelling has shown its potential in deciphering, independently, either tectonics, or morphogenesis, this strategy rests upon wealth of hypotheses regarding the other 2 aspects. We circumvent limitation by inverting coral reef terraces geometries using Monte-Carlo Markov Chain...
Understanding past sea-level variations is essential to constrain future patterns of rise in response warmer climate conditions.Due good preservation and the possibility use various geochemical methods date fossil index points, Last Interglacial (Marine Isotope Stage, MIS, 5e, 130-116 ka) often regarded as one best analogs for a climate.MIS 5e coastal stratigraphic sequences, such coral reefs, are characterized by abrupt shifts their geological facies, steps within reef topography or...
Abstract The history of sea level across the Quaternary is essential for assessing past and future climate. Global sea-level reconstructions are typically derived from oxygen isotope curves, but require calibration with geological constraints that scarce prior to last glacial cycle (>130 thousand years ago). Here we show coral reef terrace sequence at Huon Peninsula (Papua New Guinea) provides such up ∼420 ago, through a geometric analysis high-resolution topographic data. We derive...
Abstract The fossil record of Quaternary reef systems, as expressed in uplifted regions by sequences stacked terraces, has been extensively used either to understand their morphodynamics or unravel sea level variations. Yet, because these two aspects are intimately linked, analysis is often underdetermined the focuses on single sequences, along one‐dimensional profiles. Here, we take advantage lateral variations coral documenting morphological sequence Sumba Island. Near Tambolaka, northwest...

Abstract The southeastern tip of Cuba Island is limited to the south by N‐Caribbean boundary. By revisiting impressive sequences coastal terraces this region, we decipher Quaternary deformation pattern plate We present a detailed mapping uplifted over hundred kilometers coastline, and U/Th dating. At Punta de Maisí, shows (a) faster uplift close transform boundary (b) northward propagation folding produced convergence Bahamas platform toward Caribbean plate. Along southern coast sequence...
The morphology of coastal sequences provides fundamental observations to unravel past sea level (SL) variations. For that purpose, converting morphometric into a SL datum requires understanding their morphogenesis. long-lasting sequence coral reef terraces (CRTs) at Cape Laundi (Sumba Island, Indonesia) could serve as benchmark. Yet, it epitomizes pitfall challenges the ultimate goal: overall chronology its development remains poorly constrained. polycyclic nature terraces, involving marine...
Abstract Coastal boulder deposits (CBDs), named huracanolitos in Cuba, found along rocky shores, result from storms, tropical cyclones or tsunamis. Despite being important indicators for coastal hazard assessment, determining the mode of emplacement CBDs (storm/hurricane tsunami) is not easy. We present, first time English, data about shores Cuban Archipelago. More specifically, we focused on a CBD, that is, to our knowledge, largest one ever described Cuba Island. Located low‐lying coral...

To assess coastal hazard where Coastal boulder deposits (CBDs) are found, it is crucial to constrain the forces governing their emplacement: from either storms/tropical cyclones or tsunamis. Here we focus on CBDs island of Cuba and extreme climatic events responsible for formation. Four sites being studied identify produced during known hurricanes over last fifty years.The selected located a low-lying coral reef terrace Cuban shore, emplaced by hurricane 1935, Lili 1996 Matthew 2016.

Extreme marine events determine different landform imprints, such as out-of-size deposits like coastal boulders with several tons in weight. These extreme are usually connected to storms and tsunamis. Storms tsunamis characterized by a high-energy content, which is reflected wave flow height able move the boulders. Several have been detected Aruba, Bonaire, Curacao (ABC) islands, overlying terrace that surround seaward side of these islands. In this work, morpho-topographical surveys were...
The degree to which the Last Interglacial (Marine Isotope Stage 5e; ~125,000 Before Present) can serve as an analog for future sea-level rise caused by anthropogenic climate change is a matter of great importance. Refining knowledge factors such glacio-hydro-isostatic conditions and ice-sheet histories leading up since will help resolve this question, well-constrained, well-dated indicators relative sea level provide crucial data towards end. We conducted stratigraphic surveys on several...
Geological sea-level proxies, such as fossil intertidal or foreshore deposits, store fundamental information that allow reconstructing past changes in sea level, which may be used to evaluate the volume of ice sheets during warm periods. Studies on Last Interglacial (LIG; Marine Isotope Stage 5e, ~ 125 ka) proxies are particularly important, this highstand is a process analogue for current interglacial, including warming caused by human greenhouse gas emissions. In fact, LIG was...
During past Interglacial periods, global ocean volume increased as a result of the higher temperatures and melting ice sheets, consequently leading to rise in sea levels. However, on timescales ranging from years few decades, regional level variability deviates pattern, due combination vertical land movements (earth’s crust viscoelastic response glacial sheet melting, tectonics), thermohaline circulation, wind forcing water storage. Therefore, decoding sea-level during periods is...
