Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Sponsor Stated that a Jon boat might be used instead of kayak 4/17

  • Sponsor Stated that testing will most likely occur with teams of two people 4/17

  • Sponsor Preferred Slide Hammer in place in Vibration Device 4/17

    • Team has decided to omit Vibration Device at the current time

  • Sponsor Stated that when foot is removed after taking a sample the sediment would sometimes slide out due to lack of sealing 4/24

    • Team is brainstorming solutions such as method of draining seawater from sample tube to decrease weight of sample before sealing

  • Sponsor has identified location for testing of sampler device - Liberty Station NTC Park, the north end has a boat launch with sufficient sediment 4/24

  • Suggested Go-Pro with 360 Degree instead of multiple cameras 4/17

    • 2nd camera was already bought

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • Mentioned Stainless Steel in lieu of Aluminum 4/26

    • Getting Stainless Steel with thinner walls might be a better alternative due to the latter being easier to weld

  • Mentioned Adding Gussets to the slider to support it 4/26

  • Mentioned that the pole attachment could be two cylinders that fit into one another 4/26

  • Mentioned having L brackets for legs to cut through the algae and also to reduce the size of the plate that attaches the legs together 4/26

  • Mentioned to move the slider closer to the sampler if possible to reduce moment on frame 4/26
