Lo studio dei sedimenti costieri della Danimarca permette di definire le relazioni tra clima e tempeste passate. Lagune, fiordi e dune agiscono come archivi naturali: alternanze di livelli di sabbia grossolana e fini, testimoniano l'impatto di onde eccezionali. Le ricostruzioni mostrano che durante la Piccola Età Glaciale si sono succedute numerose tempeste, offrendo dati chiave per prevedere i futuri scenari di rischio costiero in risposta ai cambiamenti climatici in atto.

Danish spit systems, large sand bodies extending from the coast, serve as natural archives for reconstructing past variations in climate, sea level, and storminess. Research on the Skagen Odde spit system in northern Denmark (one of Europe's largest) and other localities has provided high-resolution records spanning the last 7,000-8,000 years.

The Lower Triassic Bunter Sandstone Fm in southern DK is a promising reservoir for geological CO₂, storage. The Volpriehausen Mb, composed of aeolian sandstones, shows excellent porosity (24.6%) and permeability (807 mD). The Rødby structure provides four-way dip closure for trapping. Experiments reveal low mineral reactivity with CO₂, mainly calcite dissolution. These characteristics make the formation a safe and efficient site for long-term carbon storage.
