Multibeam / Laser Data Acquisition

Multibeam-Laser Data Together

Boat Uses Multibeam And Laser

Seafloor Mapping Using Multibeam Sonar

Instead of sending a single beam of sound down to the seafloor, multibeam sends many individual beams to the seafloor at an angle perpendicular to the direction of survey boat.
With multibeam sonar you are seeing an image that is related to depth. Side scan is an image alone. No depths related to the image. Only depth you know is the Nadir depth.

Seafloor Mapping Using Side Scan Sonar

Side Scan Sonar images of the seafloor quality depends on resolution and how close you get the sonar to the seafloor.

Detailed Structure Using Side Scan Sonar

The line indicates the range from the Sonar to the seafloor, with towed systems.
It’s critical to watch that the sonar doesn’t hit the seafloor.

Autonomous Vehicles and Sensors

Many sensors can be installed on the boats to collect data

  • Water quality (Ph, Turbidity, Chlorophyll)
  • Depths (Single beam, Multibeam)
  • Seafloor Images (Artificial reefs, Side Scan)
  • Algae Detection and Mapping
  • Shell fish reproduction (clams, oysters)
  • Camera Images for identification

Algae Detection and Identification Realtime Sensor

  • Algae detection and mapping
  • Shell fish reproduction (clams, oysters)

Continuous Particle Imaging and Classification System (CPICS) is an imaging sensor that produces unprecedented results for in-situ aquatic microscopy of seawater, freshwater and laboratory samples.

Using darkfield illumination, the CPICS-1000-e captures high-resolution color images, showing features as small as 10um and as large as several cm.

Color information is key to high-accuracy classification while also providing important physiological information such as pigmentation due to grazing on phytoplankton.

Because of its open-flow approach to water sampling, the delicate structures of plankton and particles remain intact as to predator-prey interactions.
