About

The ISOLUME project addresses the impacts of changing marine lightscapes, particularly from coastal darkening and artificial light at night (ALAN). Led by the Leibniz Institute for Baltic Sea Research and involving partners from six European countries, the project investigates how marine lightscapes have changed over decades to centuries. Using historical data, remote sensing, and modeling, ISOLUME analyses changes in light intensity, location, timing, and spectra. It spans marine, estuarine, and freshwater systems, with case studies across Europe. Findings will support monitoring, management, and policy frameworks to mitigate the ecological effects of altered lightscapes.

Impacts

The main expected impacts are: 

  • A scientific knowledge base that quantifies changes in spectral quantity and quality of marine lightscapes on decadal timescales in European sea basins.
  • An assessment of drivers, sources and impacts of these changes at both large (~1000 km) and medium (~ 100 km) spatial scales.
  • A roadmap for implementing changes in marine lightscapes as an indicator in monitoring programmes.
  • A monitoring assessment framework for mitigating changes in marine lightscapes.
  • A policy framework for communicating changes in marine lightscapes and introducing spectral quality as a relevant observable for ocean health.
