ARCTIC BLUES, an exhibition

, ,

Returning from missions in Antarctica, biologists from Brest were asking themselves the question: how to tell their emotions about the beauty of the poles and the certainty of the disaster, in a context of scientific research?

In 2013, they propose to involve artists from all walks of life in their polar expeditions. For seven years, artists and scientists have shared missions in Arctic and sub-Arctic environments. This heterogeneous group has therefore lived in the same field between research, hesitation, failure and discovery.

The exhibition ARCTIC BLUES reflects the richness of this dialogue. Photography, video, installation, writing, sound creation, music and scientific frescoes respond to each other or collide to create a singular object: something like an attempt to blend art and science where both are revealed, with new, complementary and unpredictable colours. The exhibition highlights the shared doubts and the richness of the experiences lived during the round trips between the Brest harbour and the poles. The passer-by will discover a small part of the Ocean as well as one of the facets of the current oceanography developed in Brest over the past fifty years. ARCTIC BLUES testifies that at the tip of Brittany, improbable encounters and assertive curiosities allow the emergence of new ideas and perspectives.
This exhibition tour restores to the public seven years of research and residencies between artists and scientists within the associated BeBEST International Laboratory, a collaboration between the LEMAR laboratory (CNRS/Ifremer/ IRD/UBO) and ISMER in collaboration with the Muséum National d’Histoire naturelle.

Acoustic ecology


Passive and active acoustics each contribute to the development of an acoustic ecology through different but non intrusive and non destructive methodologies. At the scale of aquatic ecosystems, active acoustics (sounder, sonar) allows the description of the “biotic landscape”, at high spatial and temporal resolutions, providing the distribution and density of nekton, micronekton and zooplankton present between the surface and the sea bed; fronts such as the thermocline or oxycline, can also be detected. Trophic relationships or physical/biological interactions can thus be highlighted. However, clarifying these remains a complex subject. Furthermore, for the intermediate trophic levels, biomass estimates, which are essential for many research projects (trophic environment of predators, hot spots to be preserved, contribution of nycthemeral migrations to carbon flows, improvement of biogeochemical or ecosystem models), require the recognition of organisms (gelatinous, crustaceans, mesopelagic fish), which remains a real challenge. Passive acoustics listens to and studies sounds from anthropophony (boats, threshing, fishing, etc.), from geophony (rain, waves, etc.) and from biophony. In invertebrates, passive acoustics is used in a wide range of applications, including the detection and identification of cryptic or endangered species, the estimation of population density, the location of individuals, and the monitoring of activity rhythms and the reproduction period. In the near future, passive acoustics should be able to offer new tools for assessing the health of marine ecosystems by combining biology, ecology, signal processing and artificial intelligence.
