Mesophotic coral environment monitoring and habitat surveys at the Main Hawaiian Island Chain (SE1006, EK60)

The goals of the cruise were to collect a variety of data to assess the status of mesophotic corals in waters between the islands of Maui, Kahoolawe, Lanai, and Molokai. Camera surveys of corals and fish were conducted by a live feed video camera attached to a Towed Optical Assessment Device (TOAD). Three mooring, consisting of temperature and current meters, were recovered. Three pairs of Tidbit temperature loggers were deployed. CTD casts were conducted and light profiles taken at predetermined stations at midday. Mixed-gas dive operations were conducted to assess coral communities and the presence of fish, aided with cameras. Sand and gravel samples were taken for amphipod analysis. Biological backscatter were recorded using an EK60 echosounder system operating at 38, 70, & 120 kHz along predetermined transects.

Search Data
Distribution Formats
  • Kongsberg/Simrad instrument files (.raw or .wcd)(Version:1)
    • File Specification: Kongsberg/Simrad .raw files are generated by ME70, EK60 or ES60 instruments. They contain power and optionally angular position data with each beam/frequency identified by an independent channel. See the Simrad interface specification manual for further information. The .wcd files are generated by Kongsberg EM302 or EM122 instruments. See Kongsberg documentation for more information.
