Guidelines for Field Notebooks and Reports Geology 439 - Applied Magnetics One key technique separates a useful field or laboratory notebook from trash. Always record sufficient information so that somebody else can go through your notebook/report and replicate your data acquisition, experimental design, etc. Experimental and observational data than cannot be reproduced are meaningless. Accomplishing such is more difficult than you might think because when you are recording the notes and observations they are fresh in your mind. At one time or another everybody has the experience of going back to a notebook or description of some procedure that they did in the past and discovering that they no longer have a clue as to how to proceed. When it comes to recording notes, sketches, details, and description think overkill. Important Components of a Field Notebook
Project Report Most of the projects we do in this class involve experimental design, acquisition of data, downloading data, and processing those data. A cogent description of each step is an integral part of your report. Keep track of your data and back it up!. For example, for a final spreadsheet of magnetic determinations I want to see the date, time, & raw meter readings. Your working spreadsheet you print from can have several more columns so that each column is a simple, one-step, calculation - my experience is that a large number of simple calculations results in fewer and easier to catch errors than a spreadsheet that calculates everything in one column; columns and parentheses are cheap. Use the proper number of significant figures in your data and calculations and include an estimate of uncertainty. For magnetics, instrument uncertainty is +/- 1 nT for the Gem magnetometer and +/- .01 nT for the Cesium magnetometer. In detailed surveys you may need to make multiple observations at each site.
Example Outline - not restrictive or limiting Introduction/Problem Describe the goal of your study and its location. In a thesis or professional paper this section would also include results from previous researchers and a development on the importance of the project. Basically, as a writer, it is in this section that you need to catch and keep the interest of the reader. Write directly and clearly, avoid passive prose - that manual of style you bought for your English composition class might need to be dusted off. Experimental design For a field study this section should include an index map showing where you collected data, what equipment you used, references (e.g. standard textbook) to standard techniques if that is what you employed. Include a comment on why this experimental design is the appropriate one for the objective. Results This is where you include the printout of pertinent columns from your spreadsheet or copies of the printouts form the Smartseis. Other workers need to see enough of your calculations and intermediate results to verify your work. Describe the steps, programs used, additional data, etc, that were important in the development of your results. Interpretation/Conclusion Now, having caught the reader's attention in the introduction and having held it through the intervening sections, you get to interpret your results. If the experiment was successful say so. Develop your ideas and conclusions as much as you can within the reasonable constraints of your experiment; speculate a little. Generally this is where readers look for your contribution and ideas on the topic. If the experiment was unsuccessful explain what went wrong and how subsequent workers might improve on your approach. On Writing:
