An isopleth is a line drawn on a map through all points of equal value of some measurable quantity. In many meteorologic, oceanographic, or geologic studies some physical or chemical property is examined that varies from place to place on a map. Isopleths showing the quantity of the property being studied can be drawn on the map to highlight regional trends of high or low abundance of that property. This particular picture shows hydrogen ion concentration as pH from measurements made at the field laboratories in 2003.Friday, August 8, 2008
