As part of the ANERIS project, two Underwater Vision Profilers (UVP6) have been operational at key EMSO observatories, continuously monitoring marine particles and plankton populations. Their current deployment includes:

  • EMSO-OBSEA Site: Operational for 238 days at a depth of 17 meters.
  • EMSO-Smartbay Site: Operational for 81 days.

Biofouling Prevention and Maintenance

The UVP6 sensors are equipped with advanced UV-C light systems to combat biofouling on critical components, such as camera portholes and light units. This innovative measure has proven effective, supported by regular monthly cleaning by the OBSEA team to maintain optimal performance.

Data Insights: Particles and Plankton Monitoring

  • Particle Abundance: Data on small (60-128 µm) and large particles (2.05-4.1 mm) have been collected since February 2024, providing valuable insights into the dynamics of these marine ecosystems.
  • Image Analysis: High-quality images of plankton and fish are being stored and processed using EcoPart and EcoTaxa web applications. These datasets will support ongoing analyses in the coming months and years.
