Job Titles:
  • Researcher
  • Researcher / Ocean and Sea Ice Remote Sensing Group
Artem Moiseev is a physical oceanographer. He obtained his PhD in ocean remote sensing from the University in Bergen (Norway) in 2021, while employed at the Nansen Center, working with satellite data to improve how to detect ocean surface currents from space. Moiseev studies upper ocean dynamics, ocean-atmosphere, and wave-current interactions using synergy of satellite and in-situ observations and models. His main interest is in developing new solutions for observing ocean wind, waves, and surface currents from satellite Synthetic Aperture Radars. His main expertise is with Doppler shift observations from Sentinel-1 where he has been developing retrieval algorithms for retrieving ocean surface currents, signal calibration, and product validation.

Fabio Mangini

Job Titles:
  • Researcher
  • Researcher / Ocean and Sea Ice Remote Sensing Group
Fabio Mangini is an oceanographer and obtained his PhD from the University of Bergen in 2022, while employed at the Nansen Center. In his PhD, he mostly used observations to analyze the atmospheric and oceanic contributions to sea-level change in northern Europe. Manginis research interests lie within sea-level variations. Changes in sea level can happen on short and long timescales and they have different impacts on society. Mangini wants to quantify the contribution of both winds and open ocean to sea-level variations over the northern European continental shelf from monthly up to decadal timescales. In his work he uses both in-situ and remote-sensing observations to provide more robust conclusions and help identify the weaknesses and strengths of each individual observing system used today. This will make our knowledge on sea-level variations more complete, allowing for improved mitigation measures.

  • Researcher / Acoustic and Oceanography Group
Florian Geyer is a physical oceanographer. He obtained his PhD at the University of Bergen in 2010, while employed at the Nansen Center, working on measurements and models of ocean bottom currents. Geyer's main interests are data analysis and combining underwater acoustic and physical oceanography. He is very experienced in Arctic fieldwork, as he has been participating in multiple research cruises to Svalbard, Fram Strait, and the central Arctic. He also has experience in the data processing of acoustic data and data assimilation of acoustic thermometry data using the 4DVar-method.

Guillaume Boutin

Job Titles:
  • Researcher
  • Researcher / Sea Ice Modelling Group
Guillaume Boutin is a physical oceanographer. He obtained his PhD at the University of Western Brittany in Brest (France) in 2018. Boutin studies sea-ice in interaction with the ocean, most often in the marginal ice zone in the transition between drift ice and the open sea. During his PhD, he worked on modelling interactions between waves and sea ice. His favourite questions are: What happens when the ice is broken into small floes (usually by waves)? How important are small-scale sea-ice dynamics (for example small cracks in the sea ice) for the interaction between the ocean, sea ice, and atmosphere? He is optimistic that he will be able to provide answers to these questions in the near future! At the Nansen Center, he is now part of the development team for the sea ice model neXtSIM (next-generation sea ice model). To investigate how sea ice interacts with the ocean in the most realistic way possible, he has connected neXtSIM with an ocean model and a wave model (NEMO and WAVEWATCH III).

Hanne Sagen

Job Titles:
  • Project Leader

Helene R. Langehaug

Job Titles:

Igor Esau

Job Titles:
  • Senior Researcher
  • Senior Researcher / Climate Dynamics and Prediction Group
Igor Esau is a climatologist and meteorologist with a research focus on atmospheric physics and turbulence modelling. He obtained his PhD at the Uppsala University (Sweden) in 2003. Esau is working with theories, models, and data analysis related to turbulence in the planetary boundary layer - the lowermost kilometre of the atmosphere and the upper hundred meters of the ocean. Turbulence is defined as irregular motion of air and the most challenging weather conditions are found in storms (strong winds) and stills (weak winds and low air quality days). The societal calls for renewable energy, sustainable communities and climate actions have promoted the planetary boundary layer research to the top of the scientific agenda. Esau's work contributes to developing smart and sustainable cities through state-of-the-art detailed atmospheric modelling based on various observations. His overarching research question addresses the role of turbulence and the earth's surface in local climate processes. He uses physical models to understand how society interacts with nature and weather nature-inspired solutions can improve quality of our environment. This research is complemented by the search for a sustainable local climate service model. He is currently working on urban climate research and development of the models for small but vigorous - turbulent - air motions.

Laurent Bertino

Job Titles:
  • Member of the Remaining Board
  • Project Leader
  • Employee 's Elected Representative
  • Research Leader, Senior Researcher / Data Assimilation Group
  • Research Leader, Senior Researcher / Laurent
Bertino is an applied mathematician with 20 years of experience in data assimilation and ocean modelling and various other models. He obtained his PhD in geostatistics from the Ecole des Mines de Paris, France in 2001, and is now leading the Data Assimilation Group at the Nansen Center. Bertino develops and improves ways to replicate and predict what happens in the ocean, with a special focus on the Arctic. His present interests lie in the interplay of data assimilation and machine learning as well as the monitoring and prediction of sea ice and icebergs. He uses his expertise in sequential data assimilation methods like the Ensemble Kalman Filter. Numerical model simulations are hypothetical outcomes of the dynamics of a system, but do not usually match reality. Data assimilation techniques keep these simulations on track by including a regular flow of data from satellites and in-situ sensors. For example, data assimilation is able to correct the position of the ice edge and the location of ocean eddies. This allows to initialise skilful numerical predictions. One example of his work is the development and operation of the TOPAZ sea-ice and ocean forecasting system - including ocean primary production - from its first demonstration in January 2003 to its inclusion in the European services providing operational oceanography data: the Copernicus Marine Service. Bertino has led several projects applying ensemble data assimilation methods in collaboration with other disciplines, for example to soil moisture, snow depletion and volcanic ash transport. He has also led two European projects dedicated to sea-ice forecasting and the interaction of waves and sea ice. He has also managed industry-driven modelling studies in the South China Sea, in the Gulf of Mexico, and in the Barents and Kara Seas. The purposes of these studies were for example to evaluate the consequences of hurricanes or to evaluate design criteria of offshore assets.

Richard Davy

Job Titles:
  • Project Leader
  • Senior Researcher
  • Senior Researcher / Climate Dynamics and Prediction Group
Richard Davy is a climatologist. He obtained his PhD in Physics from York University (Canada) in 2009 focusing on the atmospheric boundary layer and water cycle of Mars through his work on the NASA Phoenix mission. He created models and used observations from the Phoenix lander to demonstrate that it snows on Mars. Davy has extensive knowledge on climate processes related to boundary layer meteorology and the interactions between ocean, sea ice, and atmosphere. The boundary layer is the lowermost level of the atmosphere that extends from the ground up to a few kilometers in the air. Since this is the part of the atmosphere we all live and breathe every day it is crucial to understand the process that control the conditions in the boundary layer. His work has demonstrated how boundary layer processes determine the strength of climate warming and variability as well as air pollution.
