Time series analysis for climate trend assessment

Problem addressed

Climate change is progressively altering marine and coastal conditions. Without high-quality historical data and rigorous trend analysis, it is impossible to anticipate risks, design resilient infrastructure, or plan the adaptation of ecosystems and sea-dependent sectors.

What we do and how we do it

• We compile and analyse long-term time series of oceanic and coastal variables.
• We assess trends in mean sea level, waves, sea surface temperature (SST), and shoreline position.
• We combine in situ observations, remote sensing, and climate reanalysis to increase robustness and reliability.
• We generate regional climate projections adapted to the local scale of the Bay of Biscay and other study areas.
• We deliver results in formats tailored to managers, planners, and strategic sectors.

Key benefits

• Robust knowledge of long-term changes in sea level, waves, and temperature.
• A solid scientific basis for climate change adaptation planning.
• Support for coastal and port management in addressing medium- and long-term risks.
• Practical tools to meet international commitments and European regulatory requirements.
• Strengthened positioning of AZTI as a reference in the analysis of regional climate impacts and trends.
