C03: Atmospheric composition and ocean colour feedback to Arctic amplification

PIs: Astrid Bracher, Andreas Richter (former PIs: John P. Burrows, Anne-Marlene Blechschmidt)

The Arctic ocean contains phytoplankton and serves as a source of organic and inorganic trace gases, which all directly and indirectly impact radiation in the atmosphere.  The biogeochemical processes driving the production and the exchange of these species between ocean and atmosphere, in turn, depend on temperature, radiation, and  sea ice cover. Therefore, these exchange processes are affected by and can contribute to Arctic amplification.

This project studies two types of ocean-atmosphere  feedbacks: the interaction of (i) ocean surface biogeochemistry (BGC) with radiation, and (ii) of halogen release from the ocean to the atmosphere via the cryosphere and  the resulting tropospheric ozone depletion. Main results from the first two phases of (AC)³ are: According to the merged data set of more than two decades of satellite  observations, BrO abundances during Arctic spring have increased by 15% per decade. The observed BrO-patterns are strongly driven by meteorological parameters  (temperature, wind speed, first-year sea ice) as are local ozone depletion events in Ny-Ålesund. The spatial distribution of high BrO amounts has been successfully  predicted using a neural network fed by meteorological data, but, this method did not reproduce the observed trend. Twenty years of satellite data, confirmed by in-situ  observations, show that particularly in the Fram Strait, phytoplankton stocks have increased and now incorporate more smaller groups, which are impacting surface  albedo. Numerical simulations using coupled ocean-ice-BGC modeling incorporating radiation feedbacks from biology to physics, have been performed. They show that higher summertime phytoplankton biomass (chlorophyll concentrations, Chl) and related enhanced colored dissolved organic matter (CDOM) lead to higher surface  temperatures and consequently more sea ice melt. This shortens the sea ice season by up to one month. Further local increases of Chl and CDOM are expected due to  reduced sea ice cover and increased permafrost thawing, which will amplify the observed Arctic surface warming.

In phase III, we plan to extend the time series of the  above-named key parameters established in the previous project phases of (AC)³. These mainly consist of satellite (OLCI, GOME-2, TROPOMI) but also of in-situ and  ground-based remote sensing observations, which will be used to monitor the rapid changes in ocean and atmosphere. Further, these data will be used to initialize and  validate dedicated modeling of surface water BGC with FESOM2-REcoM2 and Arctic boundary layer ozone chemistry with WRF-Chem or, alternatively, GEOS-Chem.  These models will provide all relevant parameters needed for assessing radiative feedbacks, and these will be evaluated based on their final simulations, focusing on their  relevance for Arctic amplification.

Hypothesis:

Changes in atmospheric bromine concentrations and optically active ocean components have relevant feedbacks with Arctic amplification on different spatial and temporal scales through radiative forcing and oxidative capacity.

Studies will focus on the following central questions:

  • What is the evolution of the key quantities observed (phytoplankton, CDOM, ocean radiation, BrO) over the last years, which were characterized by rapid Arctic  warming?
  • How does the changing ocean surface BGC impact atmospheric radiative forcing via indirect effects (aerosol pre-cursor emissions and carbon export) combined with its direct feedback to ocean radiation?
  • How do changing tropospheric bromine concentrations impact oxidative capacity (O3 concentrations) and thereby radiative forcing?

This project contributes to the topic of Arctic amplification by evaluating the contribution of ocean surface BGC and halogen release to atmospheric radiative forcing in a changing Arctic (SQ1 and SQ3).

Achievements phase I

In C03 first consistent, long-term, and multi-sensor data sets of phytoplankton groups (PG) and BrO over the Arctic were obtained. The time series revealed changes over the last ten years towards smaller sized and increased growth of PG, but reduced carbon export in the Fram Strait (Engel et al., 2019). Furthermore, a close link between a bromine explosion event and polar cyclone development was discovered (Blechschmidt et al., 2016). A first observational evidence of a large IO plume emitted from a volcanic eruption in Alaska was revealed (Schönhardt et al., 2017). A new retrieval algorithm of BrO (Seo et al., 2019) has been developed for the new TROPOMI onboard the S5P satellite. In addition, the first 24 years date record of tropospheric BrO over the Arctic was created and first analyses undertaken.
