Very short lived bromine compounds in the ocean and their transport pathways into the stratosphere (TransBrom)

Duration: 2009 - 2011

  • Principal Investigator PD Dr. Kirstin Krüger (RD1: ocean circulation and climate dynamics, marine meteorology) 
  • Dr. Birgit Quack (RD2: marine biogeochemistry, chemical oceanography)

Leibniz-project in the competitive procedure ("SAW-Verfahren") within the frame of the Pact for Research and Innovation 2009

Proposal in the frame of the 5th line of funding "women in scientific leading positions"


With a new transport model and hot-spot measurements in the Western tropical Pacific we want to investigate the real contribution of marine emissions of very short lived bromine compounds on stratospheric bromine. Additional bromine content of +5 ppt in the stratosphere can account for the observed but until yet unexplained stratospheric ozone loss in mid-latitudes. The questions where does it come from, how fast and in which quantities this bromine reaches the stratosphere are so far not answered and will be addressed within this national scientific community Leibniz (WGL) proposal ”TransBrom”.
