abstract: Sub-Surface Oil Monitoring Cruise (GU1002, EK60). Objectives were to evaluate ability of acoustic echosounder measurements to detect and localize a sub-surface plume of oil or related hydrocarbons released from the Deepwater Horizon well-head using the Simrad EK60 echosounder, collect fluid samples to confirm acoustc scattering targets, collect temperature, dissolved oxygen, and fluorometry profiles in the vicinity of the plume, and assess abundance and distribution of zooplankton, phytoplankton, and larval fish.
purpose: Measure volume scattering strength profiles along transects near the Deepwater Horizon well-head using EK60 echosounder and evaluate ability to characterize vertical and horizontal distribution of sub-surface oil plume.

description: The Simrad EK60 Scientific Sounder system is a new generation fishery researchtool, based on experience from the EK500. The new electronic hardware is combined with up to date PC processing and Windows operation. The EK60 provides facilities for accurate echo sounding, data storage, data analysis and reporting results. The system communication is through Ethernet, which gives flexibility in the location of the EK60 system units and allows easy access to data from other instruments or stations on a vessel network. A post processing software, BI60, is also included in the EK60 system.
