Goals:
[edit]
Ahead of time:
- assign short research topics to complete and bring to lab:
- location of all hot spots, including continental and MOR
- data on depth to magma chamber along MOR
- data on observations of macrofaunal species assemblages: MAR, East Pacific, west Pacific (island arcs), Loihi seamount
- reading: from chapter 17, p.421-423
[edit]
During lab:
- map spreading rates at mid-ocean ridges in Geomapapp
- identify and label hot spots at Iceland, Azores, Hawaii
- earthquakes along mid-ocean ridges - location and depth - spreading vs subduction
- can we plot it in Geomapapp?
- as a class, compile the datasets - where are locations of fastest spreading? does that correlate to greatest numbers of earthquakes? is there a pattern of depth to magma chamber? does hot spot location correlate to any of these? does the pattern of macrofauna biogeography correlate to any of these?
- compare to Yellowstone National Park (calderas vs earthquake activity vs hot spring locations)
- aside: what causes the hydrothermal activity in Hot Springs, Arkansas?
- before end of lab: accumulate plots, data tables, maps, etc. for use in making the class wiki for this project.
[edit]
After lab:
- write up results to contribute to class wiki for this project
- each person or group of people (should you decide) will contribute at least one table/figure/map and a short bit (a paragraph or 2, including figure caption) of explanatory text to the wiki. (Don't forget to put your name (or group of names) as the author(s) below your piece.
- You should probably check a couple times after you finish your part to see if anyone has accidentally removed part of your work (we're all new to this) or that one person's explanation doesn't say the exact opposite of your own. Should there be discrepencies in content, feel free to contact one another to resolve the issue - or as in Wikipedia, type in a comment on the page for someone to revisit.
- I will monitor progress during that week and a half and will be available for help if needed.
- This will also work as a tutorial to help you in making your term project wiki.
- Due by 8:00AM Friday Oct. 17.
- each person or group of people (should you decide) will contribute at least one table/figure/map and a short bit (a paragraph or 2, including figure caption) of explanatory text to the wiki. (Don't forget to put your name (or group of names) as the author(s) below your piece.
