Temperature: Degrees Celsius (C) can be converted to degrees Fahrenheit (F) by using the formula F = [1.8(C)] + 32. Degrees Fahrenheit can be converted to degrees Celsius by using the formula C = 0.556(F - 32).

Sea level: In this report, "sea level" refers to the National Geodetic Vertical Datum of 1929 (NGVD of 1929, formerly called "Sea-Level Datum of 1929"), which is derived from a general adjustment of the first-order leveling networks of the United States and Canada.

Note: English units are used throughout this report, except in instances where a measurement has no common English-unit equivalent.
