Online ServiceThe development of the Big Pond Dip invertebrate survey method The Big Pond Dip invertebrate survey is a simple biological quality calculated by adding together the scores for the individual animal groups ponds including landuse intensity in a 100 m zone around the pond the presence of road Read more
Chat OnlineLuckily there is a method that allows you to calculate apparent dip from true dip if the strike and bearing of the cross section line are known The apparent dip depends on the angle between cross section and strike As you saw above if this angle is 90 perpendicular then the dip you see is the true dip
