Trajectory of Cruise LGD2308 overlaid with the Swot KaRin images for June 19 (preliminary data). The ship followed the swaths between June 27 and 29. Prof. Jan, utilizing his ocean dynamic model, has predicted the presence of several oceanic eddies along this route. These eddies will be scanned using oceanic sensors installed on sea gliders deployed onboard the ship. (Credit NYCU)

In their Adopt a Crossover proposal, Professors Hwang, Chang, and Yu put forth a plan to measure sea surface heights using GNSS technology and level gauges within the coverage areas of Swot pass21 during the validation phase. The opportunity for these measurements arose when Cruise LGD2308 aboard the ship LEGEND was scheduled to sail from Kaohsiung port in Southern Taiwan to Palau between June 23 and July 3, 2023, passing through the swaths of pass21 around June 27, 2023. The principal investigator (PI) for Cruise LGD2308 is Prof. Jan, who also deployed multiple instruments to study oceanic eddies during the cruise.
