Improving remotely sensed data of the coastal zone using participatory science

Satellite remote sensing can provide accurate environmental data in the coastal zone with high spatial coverage and good temporal resolution, providing adequate in situ observations are available for calibration, validation and algorithm development. The coastal zone is among the most temporally and spatially variable regions on our planet. It is shallow, energetic and dynamic, making it difficult to sample in situ using conventional methods. Consequently, there is a sparsity of in situ data required for the validation of satellite imagery and for the development of algorithms that convert satellite signals into environmental data. New and cost-effective sampling solutions are thus needed. Here, we highlight the potential to improve in situ sampling of the coastal zone by tapping into recreation and participatory science. We draw attention to the vast number of participants that engage in recreational activities at the coastal zone, and show that, based on current technological developments, there is much potential for using recreational citizens to improve in situ sampling efforts in the coastal zone. We highlight examples of projects that have combined data collected through participatory science to test, evaluate and improve remotely sensed environmental data in the coastal zone.
