156A Week 10

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • We have finalized what we will be doing for our risk reduction and will finish our risk reduction during this week. Our upcoming schedule is:

    • Wed 3/9: Purchase parts, telescoping rod and cord dispenser fabrication

    • Sat 3/12: Test dispensing mechanisms in water

Accomplishments from Previous Week

• • Met with Chuck at Torrey Pines State Reserve

    • Attempted to find some algae locations and get Chuck to fill out budget form

    • Result of meeting: algae locations were hard to find, Chuck will talk to Dr. T about the budget

  • Met with Tom Chalfant

    • Recommended how much force to uproot the algae using a spring scale or electronic scale

    • Electronic scale gives better force estimate

  • Contacted Scripps Researchers

    • Sierra Donaldson: Benthic samplers

    • Samantha Clemen: Algae researcher

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Meet with Tom/Ian with Lab Needs form (Joseph)

  • Make telescoping rod (All)

  • Find cord dispenser (All)

  • Set-up meeting with Scripps researchers to learn more about types of samplers and algae (Bridget)

  • Outline presentation slides (David)

  • Research materials to get information about corrosion properties (ie. against salty waters) (Tanima)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments

• • Chuck

  • said we can potentially find more macroalgae in lagoons along the 101, north of UCSD if we wanted to see and feel what we are dealing with

    • We will probably visit one of these lagoons next week to find out more about algae’s physical properties

  • Reiterated project objectives: easy to use and simple design

  • He explained different types of sediment samplers: Van Veen, Ponar

    • We looked up videos to see how each sampler works and get ideas for our sampler

Instructor Comments from Last Meeting and Actions Taken to Address these Comments

• • Make sure Chuck understands the budget form

    • We gave the budget forms to Chuck on Monday

      • he said that that we should tell him what we want (ideally buy everything at once) and he will contact the SPAWAR financial contact

      • He will also contact Dr. on Tuesday to sort everything else about the form out

  • Figure out exactly what to do for risk reduction

  • Camera visibility depends on time of day, amount of pollution, etc.

Risks and Areas of Concern for Risk Reduction

• • Properly releasing the sampler

  • Properly placing the sampler

  • Ease of use

  • Sampler lifespan

Resources or Information Required but not Available

• • Methods to build telescoping device

    • Type of material (ie. PVC pipes)

  • Borrow cord dispenser from on-campus lab/engineering group or buy cord dispenser from hardware store

Schedule

• • Describe upcoming milestones

  • Update Gantt chart.

Budget (list amount spent and amount remaining)

• • $0 spent, $2600 remaining

Progress on Report and Webpage

• • None made, Webpage is not available yet
