OSUR

The research topics of the laboratories belonging to the OSU-R are :

• Atmosphere : Monitoring of atmospheric composition (reactive trace and greenhouse gases, aerosols, stratospheric ozone layer), analysis of climate patterns and effects; Study of atmospheric processes (atmospheric water cycle, stratosphere-troposphere interactions, largescale movements of atmospheric pollutants, etc.) and analysis of how
  they are appear in digital forecast models; Studies of tropical cyclones (intensification processes and trajectories).
• Lithosphere : Hydrology of catchments in volcanic ranges ; Seismology (volcanology applications, detection of cyclonic and southern ocean waves) ;Internal geophysics of volcanic ranges (landslide, erosion, magma transfer applications, etc.).
• Biosphere : forestry ecology Classification ecophysiology and climate monitoring Invasive exotic species.
• Tropical marine ecology : Tropical migratory marine megafauna ;Regional reef biodiversity monitoring of habitats in the Indian Ocean area and modification due to climate change.
• Coasts : Monitoring of coastlines ;study of erosion processes back reef lagoon coastlines.

Key research projects
In multidisciplinary topics :

• ERUPTION COLUMNS : STRAP PROJECT / (Trans-disciplinary synergy to
  face risks from eruption columns, ANR project 2015-2018),
• CYCLONIC RISKS : RENOVRISK-TRANSFER PROJECT / Integrated and
  innovative research into the natural risks associated with tropical cyclones.
  Cyclonic hazards in the “Maïdo mountains – Coast – Lagoon” workshop
  zone. Subject to the ERDF call for proposals 2015-2019.
• OCEAN-ATMOSPHERE : PROJECT TO STUDY THE PHYSICAL PROCESSES
  OF OCEAN-ATMOSPHERE INTERACTIONS IN THE SOUTH-WESTERN INDIAN
  OCEAN (SOOI) /using models and observations. Project by the OMNCG
  Research Federation (Observations of Natural Environments and Global
  Changes) of the OSU-R.
• VOLCANOLOGY AND MARINE BIODIVERSITY : CLEM PROJECT /
  Consequences of lava flows on the marine environment : focus on the 2007
  lava flow. Project managed by the OMNCG Federation of the OSU-R.
• BIOSPHERE-ATMOSPHERE : FARCE PROJECT / Forest AeRosols Clouds
  intEractions at Reunion Island. Project managed by the OMNCG Federation
  of the OSU-R.

Technical support centre and state-of-the-art equipment

• Maïdo Atmospheric Observatory. Instruments : lidars (vertical profiles for temperature, wind, water vapour and ozone) radiometers and spectrometers (partial and total atmosphericreactive trace gas columns and greenhouse gas columns) onsite analysers of atmospheric air mass (optical and chemical properties of aerosols, reactive gases and greenhouse gases) detectors of atmospheric electric activity GPS station cameras for cloud cover.
• ERORUN hydrological station in the Rivière des Pluies drainage
  basin. Three stations to measure hydrological flow and 3 weather stations.
• Saint-Gilles marine reef station. Monitoring geophysical and biological parameters in the lagoon.
• Mare-Longue forestry station in Saint-Philippe. Observation facility for forestry ecology, classification, ecophysiology and climate parameters.

The OSU-R is a partner of the European H2020 ENVRIplus project
(Environmental Research Infrastructures Providing Shared Solutions for Sciences and Society). The OSU-R observation stations are open to international access for multi-disciplinary research to be carried out with other European teams with an interest in the University of Reunion Island research facilities.
