Whether we aim to disentangle anthropogenic driven trends from natural variability or we want to assess and improve our ocean model’s capabilities to correctly display changes in time, all require high-quality observational data from multiple fixed time-series data. Until now access to these data was difficult, time-consuming, and often required solving multiple data challenges before these data were fit for the purpose. Following the successful examples set by well-known ocean synthesis products, the idea for SPOTS – the Synthesis Product for Ocean Time-Series – was born from this need to address these challenges.
