A study of Ten coastal communities along the Cross River, Qua Iboe River and Jaja Creek (all in Akwa Ibom, Nigeria) was conducted to: Identify and Geo-reference affected navigable channels in Akwa Ibom State; create a map of affected navigable channels in the state; qualitatively and quantitatively characterize floating marine debris in affected channels; Delineate the affected channels; and create awareness among coastal communities on marine litter dangers. The data for average depth revealed that the water body in Essene had the highest depth (13m) while Ufak had the least (3m); average width was highest (850m) at Akpam Nfrugam and Enitan while the least width (250m) was recorded in Ikot Ibritan; and the average flow velocity was highest (1.1 m/s) at Akpam Nfrugam and Essene, least (0.4 m/s) at Edik Ipa and Akuakpa Urang. The result of the characterization of the suspended debris showed that the debris comprised of plastic, nylon, can, foil and "others". "Others" was made up of mainly nypa palm and unidentified objects. Nylon
