Leave space for me to insert the dates. Each author's name is footnoted beginning with the numeral 2, and his or her affiliation, address, and e-mail is given. The affiliation should comprise the department, institution (usually university or company), city, and state (or nation).

Section Headings
The primary section headings should be centered and all caps, secondary headings should be mixed case and centered and ternary heading should be mixed case, centered and in italics (or underlined). For example:

INTRODUCTION
Purpose
Summary
ACKNOWLEDGEMENTS
REFERENCES
APPENDIX

Text
Do not number sections of text.

When you refer to an illustration, capitalize and spell out the word "Figure" if not in parenthesis, as in:

Figure 3 shows that the distribution of permeability is skewed, unlike porosity.

Abbreviate if in parenthesis:

The distribution of permeability is skewed (Fig. 3), unlike porosity.

Notice that you save several words if you avoid "shows that" and rephrase:

Unlike porosity, permeability is skewed (Fig. 3).

Give your results succinctly. You do not need to tell the reader to see a figure, as in:

Unlike porosity, permeability is skewed (see Fig. 3).

The reader knows to look when you refer to the figure in the text.

The word "Table" should be capitalized, and not abbreviated even in parentheses. The word "Equation"should be capitalized and spelled out in the text, as in "It follows from Equation (3) that" but capitalized and abbreviated in parenthesis, as in "It follows [Eq. (3)] that ..." If you use any other word to refer to an equation, such as "expression" or "relationship", do not capitalize.

Acknowledgements should follow text, and precede the list of references. Appendices follow references, and should be headed "APPENDIX A" etc. if more than one.

Figures

If you have multiple parts to a figure, then label them with capital A,B,C etc. Refer to them in the text as Figure 4A, or (Fig. 4A). In captions, follow this example:

Figure 4. Variograms for A, permeability, and B, porosity.

Do not embed figures (or tables for that matter) in the text of your manuscript. Print one figure per page, and list captions on a separate page of the manuscript. DO NOT put captions on figures; write your name and figure number on the back, lightly.

References

In text, captions, and table headings, list all authors if three or fewer, and just the first author followed by "and others" for more, e.g.:

( Jones, Hamilton, and Johnson, 1986; Emanuel and others, 1989)

or

Emanuel and others (1989) showed that ..., whereas Jones, Hamilton, and Johnson (1986) found that...

When giving a quote or referring to a specific fact or formula in a book or from an article of more than 8 pages, the citation should include the page number, e.g. (Chayes, 1956, p. 55), (Cherry, 1994, p. 102), or (Matheron, 1975, p. 229). Page numbers should not be given in the text when referring to the work as a whole.

As with figures, you do not need to direct the reader to "see" a citation to the literature.Be sure your references are accurate and formatted correctly.

Style
The desired length of a contribution (5000 words) equals 15 to 20 double-spaced pages with reasonable margins. Word processors can count the number of words. Be brief and to the point. An author can drop a surprising number of words to liven up a paper without losing meaning or clarity.

Words I like to cross out include: "the," and "in order to." Hence, "In order to perform the principal components analysis of dataset A, it is necessary to ..." becomes "Principal components analysis of dataset A requires ...."

Avoid statistical jargon such as ergodic in the abstract and introduction.
