Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Finished preliminary design of risk reduction test for the release mechanism
In the process of buying and machining parts for the risk reduction test
Accomplishments from Previous Week
Researched the burn wire release mechanism, and it was deemed to be too expensive for the project (though they are still being investigated)
Designed risk reduction test of a mechanical release mechanism
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Assemble and complete risk reduction test in dry conditions
Perform risk reduction test in underwater conditions if time permits
Assemble Power Point slides for risk reduction presentation
Update project webpage

Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Verify with sponsor the level of priority given to a commanded release of the buoy on the sampler as opposed to a cheaper timed release of the buoy
Met in person with sponsor on March 11th, and the sponsor stated that lower costs (~$100 per unit) was a higher priority than a commanded release but a commanded release would be preferred if it was within the budgetary constraints

Risks and Areas of Concern
In the risk reduction design there are areas of concern associated with:
jamming of the mechanical release mechanism due to misalignment of shafts and dowel pins
bio-fouling in the ocean with may interfere with the mechanical release
expense of alternative design solutions such as the burn wire system and the acoustic commanded release system
Resources or Information Required but not Available
