Equipment & Systems:

Seafloor Investigations has worked with vendors to get customized systems tailored to the acquisition of high resolution deep ocean survey data (EdgeTech 2205B), bottom samples (BoxCore) and in-field biologic & geologic processing of bottom samples (Coldlab).

  • EdgeTech 2205B Sonar
  • ColdLab Van
  • BoxCorer

Near-Bottom High Resolution Bathymetry & Sidescan Surveys

Seafloor Investigations has a dual-frequency sidescan, interferometric bathymetry customized Edgetech 2205 sonar that has been optimized for near-bottom AUV survey work rated to 6000 meter water depth. The system simultaneously acquires co-registered dual frequency sidescan and bathymetry data at 10 cm to 20 cm resolution.

 

General sonar specs can be found on edgetechs website. For exact specifications, frequencies and depth rating contact Greg Kurras; email Greg Kurras.

The Cold Van is a standard ISO 20ft refrigeration container that has been modified to meet safety requirements for human occupied portable lab space container.  It is design with an internal unistrut system to allow a reconfigurable lab space, has standard 120VAC / 20amp 60Hz power outlets throughout the van, lighting, adjustable height wood work benches and a 420 gallon cold water pump system providing cold seawater for scientific use. The van readily holds 1C internal and chills tropical surface seawater (mid 20’s C) to 3-4C within a few hours.  It has a “Carrier Thinline T-318” refrigeration unit capable of holding -29C internal with external temperatures of 38C and requiring standard 3 phase, 460 volts AC, 60 cycle, 60 amp power. The van comes with an instruction manual for each system, spares for cold water system, external hoses and hardware for adding equipment or benches to and internal unistrut system. The entire van weight ~9000 lbs.
