Mesophotic coral environment monitoring and habitat surveys at the Main Hawaiian Island Chain (SE0807, EK60)

The goals of the cruise were to collect a variety of data to assess the status of mesophotic corals in the Auau Channel, off the west coast of Maui. Camera surveys of corals and fish were conducted by a live feed video camera attached to a Towed Optical Assessment Device (TOAD). Two instrument arrays were deployed to monitor environmental variables (temperature, salinity, currents) for a period of one year. In addition, two smaller arrays were deployed to monitor temperature and occurrences of transient large fish that have been tagged previously. CTD casts were conducted at predetermined stations off a small boat, and light measurement profiles were taken at midday over a period of 4 days. Biological backscatter were recorded using an EK60 echosounder system operating at 38, 70, & 120 kHz along predetermined transects.

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.
