Marine Data i Arktis: Marine data i Arktis: Fra kartlegging til kunnskap

Dette prosjektet skal lage en dynamisk oversikt over relevante observasjons-systemer, datasamlinger og dataforvaltningssystemerfor Arktiske hav-områder og dermed øke nytteverdien av innsamlede data.

 Det er stort behov for bedre informasjon om tilstand og endringer i havmiljøet i Arktis. Klimaendringene som pågår i Arktis er betydelige og vil få langtvirkende konsekvenser for livet i havet og bærekraftig næringsutvikling i Arktis. Det produseres mye data fra polarbane satellitter, men disse er begrenset til overflaten av hav, land og is. Direkte målinger (in situ) av havmiljøet i Arktiske havområder helt er nødvendig for å estimere tilstand og endringer i havmiljøet.

NFR-INTAROS: INTEGRATED ARCTIC OBSERVATION SYSTEM (INTAROS)

 Hovedmål er å støtte opp om EU-prosjektet INTAROS for  å utvikle et integrert multidisiplinært arktisk observasjonssystem ved å utvide, forbedre og sammenkoble eksisterende systemer i ulike deler av Arktis.

 Prosjektet skal styrke deltagelsen fra norske forskningsinstitusjoner, forvaltingsorganer og industri i INTAROS prosjektet som skal gå i fem år fra 2017. Fokus er å bygge nettverk med norske aktører som har viktige roller i utvikling og drift av arktiske obervasjonssystemer. Nettverket skal bygges gjennom planlegging og gjennomføring av workshop'er, møter og dialoger med de norske miljøene.

INTAROS: 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 will 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 (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.

Polar Acoustics and Oceanography

Scientific Group Name: 
Polar Acoustics 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.
