By DEC 1st 2016 the five year INTAROS project was launched with Horizon 2020 funding from the European Commission. The overall objective of INTAROS is to develop an integrated Arctic Observation System (iAOS) by extending, improving and unifying existing systems in the different regions of the Arctic. INTAROS will have a strong multidisciplinary focus, with tools for integration of data from atmosphere, ocean, cryosphere and terrestrial sciences, provided by institutions in Europe, North America and Asia. Satellite earth observation data plays an increasingly important role in such observing systems, because the amount of EO data for observing the global climate and environment grows year by year. In situ observing systems are much more limited due to logistical constraints and cost limitations. The sparseness of in situ data is therefore the largest gap in the overall observing system. INTAROS will assess strengths and weaknesses of existing observing systems and contribute with innovative solutions to fill some of the critical gaps in the in situ observing network. INTAROS will combine many scientific disciplines of which both seismology and geodesy are included. The seismological component of INTAROS includes e.g. a reviewed catalogue of the earthquakes activity in the Arctic, to find the areas that are poorly observed and to perform a yearlong deployment of broadband OBS'es in the Arctic using ROV technology, to show how to fill the earthquake/seismic monitoring gap in the Arctic Ocean. The geodetic component of INTAROS includes e.g. that sea level information from tide gauges and from satellite altimetry (also Sentinel-3) will be combined to obtain sea level anomalies and associated geostrophic ocean currents and provide new estimations of ice sheet mass balance and changes using GNSS/GPS data and development of new methods to improve these estimations. We will give an overall presentation of INTAROS and outline the seismological and geodetic contributions.
