Procrastination rules, and I am it's ruler. A big project:
Quote:
Several months ago, thousands of small earthquakes were detected at Axial Seamount, an active submarine volcano. This may mean that an eruption has occurred, but not necessarily. Your mission is to go to Axial Volcano and find out what happened there.
Fortunately, a seafloor monitoring instrument, called a “rumbleometer” was already at Axial Volcano during the earthquakes and will provide important clues. But another ship was just out at the site and was not able to recover the rumbleometer. They could communicate with it on the bottom, so they know it is still on the seafloor, but they could not make it release and return to the surface. Why didn’t it return? Is it stuck on the bottom somehow?
We really want to get the rumbleometer back because it likely recorded information on what the volcano was doing and will help us understand what happened during the earthquakes. We know where the rumbleometer is on the bottom, but you need to go out to Axial and find out why the rumbleometer did not come up. Then you need to recover it and look at the data it recorded to figure out what happened at Axial during the earthquakes. A research ship with a remotely operated vehicle are standing by ...
In order to solve the mystery of what happened to the rumbleometer during the recent earthquakes at Axial Volcano, you will conduct the following four activities:
1) Locate an earthquake epicenter - this will tell you where the action was and where to take the ship with ROPOS
2) Record observations during a ROPOS dive - you will look for clues on the seafloor in the area around the rumbleometer
3) Create before-and-after cross-sections of the seafloor - this mapping exercise will show if there have been any changes in seafloor depth since the previous survey was done before the earthquakes
4) Analyze data from the rumbleometer - pressure and temperature data recorded by the instrument will give important information about what happened
Segment 1:
Completed Project Overall
Graded on Professionalism & Neatness
Good (what I am looking for): including but not limited to folder, Cover sheet in front, Title page incl. Name, Class, Section, Date, Neatness, Business like print quality, Electronically prepared, ...
Bad (point deductions): Cut n’ paste, missing Name on any or all of the parts, sloppy appearance, stains, handwritten, missing segments, out of order, etc....
Segment 2:
Locating Earthquake using Triangulation
Graded on Triangulation Map & Hydrophone distance calculations
Good (what I am looking for): table & calculations in Excel, map showing hydrophone Locations, distance circles, epicenter location, epicenter coordinates, etc.,...
Bad (point deductions): Poor drawing; sloppy work; NO long.-lat. For epicenter, wrong location, missing circles, etc.....
Segment 3:
Ocean Floor Traverse
Graded on Correctness & Completeness
Good (what I am looking for): Excel Table addressing the following questions: Old or new lava? Lava collapsed or uncollapsed? Hydrothermal Vent present: Old or New? List of observed animal species ...
Note: Best to transcribe the table presented in the power point into Excel
Bad (point deductions): including but not limited to missing or sloppy / unprofessional work, not Excel, not enough detail, NOT observed, etc...
Segment 4:
Contour Profiling & Map
Create five (5) contour profiles using the Contour Profile Worksheets presented in this Power Point. Can be hand drawn if neat AND orderly. Mark & shade the POST-event profile in Red.
Post-event Map: Mark east and west boundaries of new lava flow in red on map roughly following the contour lines, to define boundary and extent of new lava flow
Graded on drawing neatness, correctness, completeness
Good (what I am looking for): including but not limited to clean cross section and map, ALL 5 sections present, NO errors, color coded differentiating between pre and post event, relying on data...
Bad (point deductions): including but not limited to missing or sloppy work, incomplete data or map, no color coding, illogical compilation, etc. etc....
Segment 5: Rumbleometer Data & Conclusion
After plotting data electronically, type a concluding paragraph explaining what happened to the Missing Rumbleometer drawing on ALL the activities.
Note: The questions presented throughout the exercises will help you to draw the proper conclusion in your write-up. It is NOT necessary to answer each question individually!
Graded on use of Excel, Quality, Neatness, Language
Good (what I am looking for): Excel data graphs, professional write-up, logical explanation using ALL the data, detailed, etc...
Bad (point deductions): including but not limited to missing or sloppy / unprofessional work, hand-drawn, poor grammar / composition, etc....

As well as 10 online quizzes, all of which are due by noon tomorrow, and none of which I have started. Huzzah.
