Analysis of Arctic ices by Remote Raman Spectroscopy

A portable remote Raman instrument for field analysis has been developed. This instrument has been tested in the Arctic conditions during AMASE (Arctic Mars Analog Svalbard Expedition) campaigns 2007, 2008 and 2009. Besides its capability for mineral detection the remote system proved to be a very useful tool for ice structural analysis of icebergs and ice-wall in glaciers. For the first time at our knowledge Arctic ice has been analyzed in situ in different conditions and at distances ranging from 10 to 120 m. The spectra obtained have enough quality to be used for quantitative spectral analysis.

► We developed a portable remote Raman instrument for field analysis.
► The instrument enables mineral identification and structural ice studies at distance.
► Arctic icebergs were analyzed up to 120 m distance.
► Spectra obtained enable detailed structural analysis of natural ices at these distances.
