UNDER-ICE: Arctic ocean under melting ice

UNDER-ICE is an interdisciplinary project involving physical oceanography, ocean acoustics, sea ice research and studies of biological production (net community primary production) in Fram Strait and northwards towards the Gakkel Ridge.

The project will focus on observational and modelling studies of water masses, fluxes and physical-biological processes in ice-covered areas and the marginal ice zone (MIZ). Innovative observing systems based on ocean acoustics, hovercraft and gliders will be applied to collect ocean and sea ice data in a series of field experiments from 2013 to 2016. The new data will be combined with existing data, including satellite data and state-of-the art numerical models to study processes of importance for the Arctic climate system.

ACOBAR II: Analysis and publication of results from the Fram Strait tomographic experiment.

The aim of the ACOBAR II is to facilitate for continued collaboration between and Nansen Environmental and Remote Sensing Center (NERSC) and Scripps Institution of Oceanography (SIO). 

The aim of  ACOBAR II is to facilitate for continued collaboration between and Nansen Environmental and Remote Sensing Center (NERSC) and Scripps Institution of Oceanography (SIO). This will result in a significant transfer of knowledge within acoustic data analysis, and  acoustic inversions  and assimilation of acoustic measurments into ocean models from SIO to NERSC. The collaboration will be implemented through mutual visits at the two institutions of key personnel within acoustics, oceanography, and ocean modelling.

The research activities are mainly in the areas of remote sensing of sea ice and oceanographic processes including ocean acoustics.  Work includes ocean and sea ice field work with data collection and data analysis.  In sea ice research data from different types of satellite sensors are used for studies of sea ice classification, drift, thickness and processes such as leads, polynyas and ridges. Validation of sea ice remote sensing data uses data from in situ observations.

DAMOCLES: Developing Arctic Modelling and Observing Capabilities for Long-term Studies

DAMOCLES is an integrated ice-atmosphere-ocean monitoring and forecasting system designed for observing, understanding and quantifying climate changes in the Arctic.

DAMOCLES aims at reducing the uncertainties in our understanding of climate change in the Arctic and their impacts. The Arctic over the last 2-3 decades has warmed more than other regions of the world, and the sea-ice cover has decreased significantly in the same period. A first-order scientific and societal question is whether the Arctic perennial sea-ice will disappear in a few decades (or even faster, as predicted by some state-of-art climate models).
