CRIMEA CRIMEA: Contribution of high-intensity gas seeps in the Black Sea
to methane emission to the atmosphere
The CRIMEA project focuses on the transfer of methane from the
seafloor through the water column and into the atmosphere from
submarine high-intensity methane seeps and outbursts in the
Black Sea. The aim is to evaluate their possible contribution to
changes in atmospheric composition, and their possible impact on
climate processes. The project is innovative as it focuses on high-
intensity seeps that vigorously eject methane into the water
column or immediately into the atmosphere. Such seeps are more
likely to have a pronounced effect on atmosphere and climate than
the "normal" steady seeps where the larger part of the methane is
dissolved and oxidized, consumed by bacteria or fixed in seafloor
carbonate crusts.
GEOMAR is a leading specialist in the scientific study of hydrates,
seeps and seep-associated processes. It is involved in several
WPs. It participates in the seismic surveys, in close co-operation
with RCMG, and is responsible for the multi-beam survey.
GEOMAR is the convener of WP3. It executes the flare-imaging
survey for mapping gas jets and plumes. It deploys a newly
developed Fluid-Flow-Observatory for measuring the flux of
escaping gases and performs in-situ analyses of escaping gases.
It also plays an important role in WP5, where it deploys a novel
methane equilibrator to analyze methane content and flux in the
surface waters and the air, and it is involved in the isotopic
analyses.
