Kona Integrated Ecosystem Assessment Survey (SE1401, EK60)

This cruise accomplished the following objectives: Oceanographic data were collected from a total of 6 CTD casts and continuous TSG measurements along a predefined grid off the west coast of Hawaii to assess the influence of physical dynamics on the region's biological productivity. CTD-mounted fluorometer measurements were carried out by two fluorometers. Biological backscatter was monitored using the EK60 echosounder system, both during trawl operations and along 7 acoustic transects (including at least one daytime and one nighttime transit of each transect). One nighttime oblique mid-water trawl was conducted prior to the net being damaged beyond repair by contact with the seafloor. Four casts of a DIDSON imaging sonar were conducted to collect high resolution information on the density of high sonic scattering layers. An ROV was deployed 5 times to investigate acoustic scattering layers and adjacent layers. Deep handline jigging was accomplished during day and night to investigate scattering layer macrofauna. Data on cetacean distribution, school size, and school composition were collected via daytime visual surveys on 9 days of transects coupled with several days of small boat survey effort. Two HARP units were deployed for passive autonomous detection of cetaceans and several sonabuoys were also deployed during daytime operations for cetacean detection and identification.

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.

Purpose The scientific objectives of this cruise are to collect information to describe the physical, chemical, and oceanographic environment as well as observe cetacean activity along the west coast of Hawaii as support for the monitoring component of the NOAA Kona Region IEA. The proposed survey grid will allow comparison of oceanographic features between the Kohala shelf region to the north and the deeper offshore regiono to the south as well as near shore and offshore.
