Chapter
The Redes Natural Park is located in the southeastern sector of the Principality of Asturias (43° 13′ N, 4° 58′ W). Most of its territory (378 km²) falls within the headwaters of the Nalón River, one of the main rivers on the northern slopes of the Cantabrian Mountains. The glacial landforms, discovered toward the latter half of the 20th century, i...
Chapter
This chapter describes the characteristics of the glaciers at the surroundings of the Lake Sanabria (42° 7′ 22.08″ N and 6° 43′ 4.99″ W; 1005 m), the largest lake of glacial origin in the Iberian Peninsula, and its drainage basin, located on the eastern slope of the Trevinca Massif (northwest of the Iberian Peninsula). The surroundings of the Lake...
Article
Numerous cases of timing differences between glacier advances recorded in mountain environments have been documented over the last decade, usually suggesting potential age conflicts between the different dating techniques. The frequent use of a single technique to date numerically a given glacial sequence makes it difficult to address to what exten...

As major calcifiers in the open ocean, coccolithophores play a key role in the marine carbon cycle. Because they may be sensitive to changing CO2 and ocean acidification, there is significant interest in quantifying past and present variations in their cellular calcification by quantifying the thickness of the coccoliths or calcite plates that cove...
Article
Glacial erosion of hillslopes and stress changes induced by the transition from glacial to non‐glacial conditions exert a strong influence on slope instability and are considered among the scope of paraglacial geomorphology. Failure mechanisms and coupling between paraglacial rock‐slope failures (RSFs) and fluvial erosion are difficult to define. H...

Article
The geomorphological evolution of the Cobiheru Cave shows the influence of the non-carbonate coastal mountain ranges on coastal karst evolution, as well as the temporal distribution of the cold-adapted fauna sites in the Cantabrian Coast. Geomorphological observation and U/Th dating lead to the construction of an evolution model. The model comprise...
Article
Carbon isotopic fractionation during photosynthesis (εp) is used to reconstruct past CO2 and phyto-plankton growth rates, typically by measuring the δ13C of biomarkers produced by coccolithophorids. However, organic molecules bound within diatom frustules represent another phase for measurement of δ13C and offer the opportunity to obtain εpfor spec...

Full-text available
Marine algae are instrumental in carbon cycling and atmospheric carbon dioxide (CO2) regulation. One group, coccolithophores, uses carbon to photosynthesize and to calcify, covering their cells with chalk platelets (coccoliths). How ocean acidification influences coccolithophore calcification is strongly debated, and the effects of carbonate chemis...

Full-text available
New data about the geomorphology and paleoenvironmental evolution of the Cantabrian Coast for the MIS 6-4 interval is derived from the speleogenetical model of the Cobiḥeru Cave. This data includes: (1) the identification of 2 phases of cave sedimentary infill related to cold conditions and global sea-level lowstand at ca. 60–70 and 130–150 ka, (2)...
Article
Extreme precipitation events may cause flooding in the subsurface as well as surficial drainage networks, and these flood events may be preserved in the speleothem archive. We describe here a study of stalagmites from the Cueva Rosa, a system with a perennial cave stream in a lower active level and abundant speleothems in a fossil gallery 6e8 m abo...
Article
Extreme precipitation events have a disproportionate impact on landscape evolution and on human constructions, and the frequency and intensity of extreme events may vary with changes in mean climate in the past and in the future. We document the potential for cave sediment archives to record past changes in the frequency of flooding events by chara...
Article
Speleothem growth requires humid climates sufficiently warm to stimulate soil CO2 production by plants. We compile 283 U/Th dates on 21 stalagmites from six cave systems in the NW coast of Spain to evaluate if there are patterns in stalagmite growth that are evidence of climatic forcing. In the oldest stalagmites, from marine oxygen isotope stage (...
