Lateglacial and Holocene chronology of climate‐driven postglacial landscape evo...
Garcia‐Oteyza, Julia; Oliva, Marc; Palacios, David; Fernández‐Fernández, Jose Maria; Schimmelpfennig, Irene; Fernandes, Marcelo; Giralt, SantiagoThe Greenland Ice Sheet is highly sensitive to climate change, leading to significant retreat along its edges. This rapid ice loss contributes to rising sea levels and impacts the Earth’s climate stability. Understanding the extent of recent glacier retreat is crucial in order to determine if it is unprecedented or within ranges of natural variability. Palaeoenvironmental studies aim to identify past glacial ph...
The timing of the deglaciation in the Atlantic Iberian mountains: Insights from...
Hernández, Armand; Sáez, Alberto; Santos, Ricardo N.; Rodrigues, Teresa; Martin‐Puertas, Celia; Gil‐Romera, Graciela; Abbott, Mark; Carballeira, RafaelUnderstanding the environmental response to the last glacial termination in regions located in transitional climate zones such as the Atlantic Iberian mountains is crucial to estimate potential changes in regions affected by current glacial melting. We present an 8.5 m-long, solid last deglaciation and Holocene chronostratigraphic record including detailed sediment analysis from Lake Peix˜ao, a pro-glacial lake...

Holocene glacial oscillations in the Tyroler Valley (NE Greenland)
Garcia‐Oteyza Ciria, Julia; Oliva, Marc; Palacios, David; Fernández-Fernández, Jose M.; Schimmelpfennig, Irene; Medialdea, Alicia; Fernandes, MarceloAlthough the spatiotemporal oscillations of the Greenland Ice Sheet (GrIS) during the last millennia have played a prominent role in global environmental changes, its glacial response to the natural variability still needs to be better constrained. Here, we focused on the reconstruction of the glacial behavior and deglaciation process along the Tyroler Valley (74° N, 22° E), within the Northeast Greenland Natio...

The deglaciation of Barton Peninsula (King George Island, South Shetland Island...
Oliva, Marc; Antoniades, Dermot; Serrano, Enrique; Giralt, Santiago; Liu, Emma J.; Granados, Ignacio; Pla-Rabes, Sergi; Toro, Manuel; Hong, Soon GyuBarton Peninsula is an ice-free area located in the southwest corner of King George Island (South Shetland Islands, Antarctica). Following the Last Glacial Maximum, several geomorphological features developed in newly exposed ice-free terrain and their distribution provide insights about past environmental evolution of the area. Three moraine systems are indicative of three main glacial phases within the long-t...
Detection of tephra layers in Antarctic sediment cores with hyperspectral imaging
Aymerich, Ismael F.; Oliva, Marc; Giralt, Santiago; Martín-Herrero, JulioTephrochronology uses recognizable volcanic ash layers (from airborne pyroclastic deposits, or tephras) in geological strata to set unique time references for paleoenvironmental events across wide geographic areas. This involves the detection of tephra layers which sometimes are not evident to the naked eye, including the so-called cryptotephras. Tests that are expensive, time-consuming, and/or destructive are ...

Oliva Franganillo, Marc; Antoniades, Dermot; Giralt, Santiago; Granados, Ignacio; Pla Rabes, Sergi; Toro, Manuel; Sanjurjo, JorgeEl proceso de deglaciación de las actuales áreas libres de hielo existentes en la zona de la Antártida marítima tiene notables repercusiones geomorfológicas y ecológicas. No obstante, la cronología del retroceso glaciar es aún poco conocida. Éste es el caso de las áreas deglaciadas existentes en las penínsulas Byers (isla Livingston) y Barton (isla King George). La datación de la base de los sedimentos recupera...
