    • Satellite Tagged Net Locations NWHI 2018 - 2021

    Metadata Updated: March 16, 2024

    This pilot study follows the movements of 6 derelict fishing nets over time to study how far derelict nets can travel within an atoll, and how long they remain stationary. Six floating derelict fishing nets were located and tagged with satellite buoys in Pearl and Hermes Atoll in the Northwestern Hawaiian Islands during a marine debris removal mission in 2018. Locations of the 6 nets were transmitted every four hours from 09-30-2018 until the buoys broke free or stopped transmitting due to technical reasons. Last known stationary locations were surveyed on a return mission in September of 2021, and 4 of the 6 nets were relocated.

    Lineage Data were downloaded using ELB 3010 Manager software. Locations were imported into csv file, symbols in coordinates were replaced in excel, then the files were loaded into the software program R. In R, date and time were separated and formatted to have consistent formats, and coordinates were converted to decimal degrees. Several points of bogus transmissions were removed, and all files were combined into one (raw data is one file for each buoy for each month).
