Combining recent advances in remote sensing and aerial survey, a new system for airborne current measurement has been developed to bridge the gap between satellite- and vessel-based ocean current measurements. ROCIS, the Remote Ocean Current Imaging System, combines Fugro expertise in airborne survey and operational oceanography with state-of-the-art technology and oceanographic research from Areté and Associates.

ROCIS uses an innovative surface current measurement technique to significantly enhance understanding of current phenomena in coastal and offshore areas. Using high-resolution airborne photography, the system images surface waves and retrieves surface current data from the Doppler shift of successive surface wave images. Current data can be collected at altitudes between 3,000 and 10,000 feet (900 and 3,000 metres).

Over a wide operational area, near real-time synoptic surface current data are provided, while fine resolution is available for assessing smaller scale current features. The data can be used in combination with satellite, numerical model and in situ measurements, offering better understanding of offshore current features and enhancing operational planning. Information can also support the calibration and validation of predictive models.
