Habitat Mapping Camera System The Sea Scallop Project

Commercial scallop fishermen, scientists and engineers working together

175 kHz AST synthetic aperture Side scan sonar Imagenix 600 kHz side scan Stereo optical imaging 30m 2m Kongsberg EM3002 300 kHz multibeam HabCam The HabCam is towed 2 m (6’) above the seafloor and takes 5 images per second, with a 1 m (3’) field of view

Fishermen have a wealth of at-sea experience and are essential to the success of cooperative research projects

Scallops are counted and measured along the track-line to provide biomass estimates

Sand and gravel Cobble Assess the composition of the seafloor

HabCam Lesson 1 - Activity 2 Objective: IDENTIFY SUBSTRATE ON THE SEAFLOOR Directions: Ask the students to again assess each of the 50 images and now determine what the seafloor is mostly comprised of. Students can double check their species tallies as they perform this activity. Use the sheet below as a guideline and circle which substrate type suits the images the best (just a sample of what the activity sheet would look like is provided): Sand Sand/Gravel Gravel Cobble Boulder Sand Sand/Gravel Gravel Cobble Boulder Image 1: Image 2: Sand Sand/Gravel Gravel Cobble Boulder Image 3:

HABCAM LESSON 2 Directions: Out of the 25 images provided which contain species behaviors in them, try to guess which behavior it is and color in the appropriate circle. Tally up the number of different behaviors observed and compare with the expert results. A sample of what the activity sheet would look like is provided below. ,[object Object],[object Object],[object Object],[object Object],Predation Interaction Camouflage Commensalism Image 1: Predation Interaction Camouflage Commensalism Image 2: Predation Interaction Camouflage Commensalism Image 3:
