Research possibilities and resources
Background and research topic: The ocean stores the vast majority of heat in the climate system and distributes this heat, nutrients, carbon dioxide, and salts around the globe. Exchange occurs with the atmosphere at the surface and with surrounding waters along the pathways of major ocean currents. The Nordic Seas are a key transit region for the Atlantic Meridional Overturning Circulation, crucial for Earth’s climate with its poleward flowing warm, saline Atlantic Water that is progressively cooled and densified. The Norwegian Sea forms a large heat and salt reservoir with substantial air-sea interactions, intense atmospheric phenomena such as polar lows and cold air outbreaks, large wintertime heat losses, and intense mesoscale eddy activity. These processes, interactions, and feedbacks are particularly enhanced in frontal regions, which are also key to fisheries due to associated upwelling providing nutrients. Despite the significance of these processes, there are still shortcomings in our understanding of these crucial air-sea interactions and how they affect the upper ocean stratification, distribution of nutrients, and energy transfers in the ocean across scales.
The target region features several distinct fronts, the most prominent being the front between the Atlantic and Arctic waters between the Norwegian and Greenland seas over the Mohn Ridge and a persistent vortex in the Norwegian Sea. The prominence of these temperature gradients allows for idealized studies of air-sea interaction combining observations and models. Over the past decade, we have collected high-resolution oceanographic data using a combination of state-of-the-art measurements from ship and autonomous, robotic platforms, enabling detailed process studies in the ocean ranging from regional to small scales. In addition to ongoing collection of new data using ocean gliders, moorings, and ships, the novel satellite product from SWOT (Surface Water and Ocean Topography) will be available from late 2022, providing unprecedented wide-swath and high-resolution observation of the sea surface elevation variability.
The project aims to combine ocean glider observations with atmospheric data and idealized numerical models, addressing coupled atmosphere-ocean processes, the oceanic response, and feedback mechanisms. In particular, we will focus on (a) the impact of severe atmospheric events during winter on the mixed layer development in the Nordic Seas, (b) the energy transfer in the ocean from the mesoscale and submesoscale down to mixing scales at the baroclinic front along the Mohn Ridge and in a quasi-symmetric vortex in the Norwegian Sea under different forcing conditions, (c) subduction rates and meso/submesoscale dynamics and variability across the Mohn Ridge, and (d) on processes and feedbacks between the atmosphere and ocean.
Opportunities and infrastructure: (1) Field studies and data collection from research cruises, moorings, and ocean gliders including infrastructures NorGliders and NorEMSO; (2) possibility to be trained and participate in operations as a ocean glider pilot; (4) access to high-quality data from the Nordic Seas; (3) integration in a multi-disciplinary research group within the Bjerknes Centre for Climate Research.
Supervisors: Ilker Fer (PhD, 2001, EPF-Lausanne, Switzerland) is professor of physical oceanography at the Geophysical Institute, University of Bergen. He is the leader of the research infrastructure, “the Norwegian node for the European Multidisciplinary Seafloor and water column Observatory” (NorEMSO), and of the “Norwegian National Facility for Ocean Gliders (NorGliders)”. His research interests cover meso to small scale processes in physical oceanography with special attention to high-latitudes, ocean mixing and turbulence, and atmosphere-ocean-ice interaction. He is an observational oceanographer with field experience at sea and on ice, and has led more than 25 expeditions since 2000. Fer has expertise in collecting, processing and analysing data from conventional ship and moored instruments, as well as from various complex platforms including microstructure profilers, gliders, moored profilers, and eddy-covariance systems. He has extensive experience in leading projects, publication of research results as well as supervision of graduate students and post-doctoral researchers.
Thomas Spengler (PhD, 2008, ETH Zurich, Switzerland) is a professor in meteorology at the Geophysical Institute, University of Bergen. He is the leader of the dynamic meteorology group and director of the Norwegian research school on Changes in Coupled Earth System (CHESS). Spengler has worked extensively on air-sea interactions in the higher latitudes, focusing on extreme polar weather phenomena, such as polar lows and cold air outbreaks. He has a particular interest in air-sea interactions and their role on the couple climate system. Spengler has expertise in theoretical and numerical model simulations addressing air-sea interactions, where he focuses on detailed process understanding mapping sensitivities of the coupled system. He has significant experience in leading research projects as well as supervision of graduate students and postdocs, and has a respectable publication record.
International collaboration possibilities: Scripps Institution of Oceanography and University of Washington, USA; Mediterranean Institute of Oceanography, France; University of East Anglia, UK; Institute of Atmospheric Physics, Chinese Academy of Sciences, China.
Impact of research project: Understanding the physical processes and feedback mechanisms of the coupled atmosphere-ocean system has significant ramifications for our knowledge regarding implications for the oceanic ecosystem including its biosphere. Atmosphere-ocean interactions in this crucial region of the Nordic Seas have influences both globally, through the Atlantic Ocean overturning, and locally on weather, ocean circulation, ocean ecosystem and fisheries in the Nordic Seas. With the warm and salty Atlantic Water being subject to the greatest heat losses anywhere in the Nordic Seas, the Norwegian Sea is a key player in global climate. These heat exchanges and upwelling associated with ensuing changes in ocean circulation also matter to fisheries, because the advection of nutrient rich waters support the entire food chain, sustaining the productivity around Norway.
