In this paper we introduce, for the first time, a portable on-board Surface Enhanced Raman Spectroscopy (SERS) Sensor System on an Artic sea-trial, applying a 671 nm microsystem laser diode. During a three-week cruise on the James Clark Ross (JCR) research vessel in August 2011, the measurements of Arctic water column and sediments were taken around 78 N and 10 E. Raman and SERS spectra of Arctic surface and sediment water are presented as well as the results of short-time and long-time substrate stability tests. Spiking experiments with PAHs (anthracene, fluorenthene and pyrene) in different concentrations were also carried out.
