The Marboré Symphony: a Science - Art Collaborative Project to increase Global Change Awareness based on a Deglaciation and Holocene Pyrenean high altitude lake sediment sequence

Earth scientists and musicians have collaborated to create music to illustrate the changes in a high altitude (2612 m a.s.l) Pyrenean lake since deglaciation and to increase awareness about global changes in mountains environments. Based on the sediment sequence from Marbore Lake (42°41′44.27″N, 0° 2′24.07″E) we have selected lithological, compositional and pollen data to represent the main climate, environmental and limnological changes in the lake and the region during the last 15000 years. To transform the geological data into music, notes were assigned to compositional range intervals and the tempos were degned using sediment accumulation rates. The electronic version of the Marbore Symphony was created by computer software based on the raw data. Different melodies and instruments were assigned at each data set as they inform about lake bioproductivity (organic carbon, Br/Ti) vegetation dynamics in the valleys (pollen), sediment iniux (Si/Ti) and anthropogenic impact (Pb/Ti). Based on the electronic v...
