Kona Integrated Ecosystem Assessment Survey (SE1304, EK60)
This cruise accomplished the following objectives: Oceanographic data were collected
from a total of 21 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. Chlorophyll was measured for ten discrete samples per CTD using
a bench top Turner 10-AU fluorometer. Water samples were preserved for post-cruise
flow cytometry to determine phytoplankton size structure. Biological backscatter
was monitored using the EK60 echosounder system, both during trawl operations and
along 71 acoustic transects at 38, 70, and 120 kHz frequencies. Twenty two nighttime
oblique mid-water trawls were conducted targeting the shallow sound scattering layer.
Visual surveys for a total of 70 hours were conducted to collect data on cetaceans.
A Seaglider was successfully deployed to collect temperature, salinity, and fluorometry
data.

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. |
