INTAROS: H2020: Integrated Arctic Observation System

INTAROS is a research and innovation action under the H2020-BG-09 call in 2016 and will run from 2016 to 2021.

INTAROS develops an integrated Arctic Observation System (iAOS) by extending, improving and unifying existing systems in the different regions of the Arctic. INTAROS has a 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 (EO) 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.

NextGEOSS: Next Generation GEOSS for Innovation Business

The NextGEOSS project will implement a federated access for Earth Observation data, including user friendly tools for data mining, discovery, access and exploitation.

The NextGEOSS project will implement a federated data hub for access and exploitation of Earth Observation data, including user-friendly tools for data mining, discovery, access and exploitation. This data hub will be supported by a strong commitment to the engagement of Earth Observation and related communities, with the view of supporting the creation of innovative and business oriented applications. NextGEOSS engages main providers of Earth Observation data, including Copernicus Collaborative Ground Segments and Core Services.

EU invites the Nansen Center to negotiations on two prestigious Arctic projects

Two large projects proposals to the Horizon 2020 Blue Growth - Demonstrating an ocean of opportunities call, respectively coordinated by and with major participation from Nansen Center, have today been invited to negotiations with the European Commission. Prof. Stein Sandven coordinates the Integrated Arctic Observing system (INTAROS) project. Prof. Yongqi Gao is a key partner in the Blue-Action: Arctic Impact on Weather and Climate project coordinated by the Danish Meteorological Institute and Max-Planck Institute for Meteorology.

The soundscape in the Marginal Ice Zone

Youtube movie - UNDER-ICE acousticsThe soundscape in the Marginal Ice Zone (MIZ) is comprised of seismic airgun noise, ship cavitation noise, and natural background noise due to different geophysical processes in the MIZ. Cavitation noise from the research ice-breaker dominated the sound scape at times.

ONR-Acoustics: Under-ice Acoustic propagation

The impact of sea ice on acoustic propagation is one of the least understood in Arctic propagation, because it is a combined effect of reflection (ice thickness and material properties) and scattering from a highly variable and rough surface. 

The work in this project includes analysis of acoustic and oceanographic data collected in several field experiments as part of the WIFAR, ACOBAR, and UNDER-ICE projects (funded by EU and the Norwegian Research Council). Acoustic observations are analyzed and we use acoustic models (OASES and RAM) to understand the results.

Acoustic and Oceanography

Scientific Group Name: 
Acoustic and Oceanography
Take a leading role in the development, implementation and scientific use of a Pan Arctic Ocean Observing System

Carry out fundamental acoustic research for applications within sea ice research, oceanography, environmental monitoring, underwater communication and geo-positioning.

Carry our fundamental oceanographic research for improved estimates of the heat, mass, and freshwater fluxes and storage in the sparsely sampled Arctic region by combining direct measurements with numerical models. Acoustic remote sensing provides one of the few ways to observe the abyssal ocean.

Ocean Flagship: Ocean Flagship

The Ocean Flagship is established bringing together main partners involved in the long-term ocean observations around Svalbard. The project will initiate a new Svalbard Science Forum (SSF) flagship program.

The main goal of the proposed SSF Ocean Flagship is to increase scientific cooperation between all countries and institutions actively involved in the marine research in the Svalbard area. At present the individual elements of the ocean observing system in Fram Strait and the European Arctic are mostly project-related and therefore relatively dispersed and independent. Moreover, the information flow between different players in ocean observations is rather limited.
