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

• • Goal: improve protocol statewide (time-based) (5/18)

    • Takes too long to sample large estuaries

  • Previous sampler is limited to arms length (5/18)

  • *Kayak is essential* (5/18)

    • Either (2) kayaks or (1) 2-person kayak

  • Trigger mechanism (5/18)

    • Try to avoid something spring loaded

    • Options include: rope, Lokklathc, barrel release (I hook)

  • Updates (5/18):

    • Splitting into two pieces

      • One goes into water and the other one stays on land

      • We need ~4in +  sediment

  • Ocean Instruments (5/18)

    • Talk to manufacturer

    • Contact information from kara

  • Other (5/18)

    • Longer rod

    • Spring constant kx

  • We can modify one sampler

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

• • Replacement for Wire Hook (5/17)

    • Lokklatch

    • Is it easy to mount?Safer?

    • 3D drawing would be helpful

  • Consider triggering both latches at the same time (5/17)

  • No optimization needed on "cutting" edge since the cylinder is beveled (5/17)

  • Camera (5/17)

    • Mounting, illumination issues

  • Presentation is graded based on (5/17):

    • Content

    • Easiness to be understood

    • Oral Communication

      • No "uhhh", "ummm"

    • Metric Units (english units in parantheses)

    • Annotated figures

    • Bullets-not sentences

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • N/A

Risks and Areas of Concern

• • Team discovered at the last sponsor meeting that this was Kara's project and that it has to be optimized for kayak use

    • Team can no longer assume that frame could be used on land/jon boat

    • Team might have to redesign some components(Downscale) for kayak use which might take more time

Resources or Information Required but not Available

• • Manufacturer Contact Information

Schedule

• • Improving Prototype for the next two weeks with addition of some key mechanisms

    • Foot Trigger Mechanism

    • Replace Foot Hook

    • Pole Attachment and 0.1 meter hard stop
