This article illustrates the floral-dip method of Agrobacterium tumefaciens -mediated transformation of Arabidopsis thaliana. By introducing a cell-cycle regulated promoter-reporter, pTSO2::β-glucuronidase (GUS), into Arabidopsis, we illustrates how one detects GUS reporter expression in transgenic seedlings.

Agrobacterium-mediated transformation using a floral-dip method can be successfully employed to create stable transgenic lines of the extremophyte model Schrenkiella parvula. We present a protocol modified from that for Arabidopsis thaliana, considering different growth habits and physiological characteristics of the extremophyte.

Determining Spatial Orientation of Rock Layers with the Brunton Compass

Source: Laboratory of Alan Lester - University of Colorado Boulder Most rock units exhibit some form of planar surfaces or linear features. Examples include bedding-, fault-, fracture-, and joint-surfaces, and various forms of foliation and mineral alignment. The spatial orientation of these features form the critical raw data used to constrain models addressing the origin and subsequent deformation of rock units. Although now over 100 years since its invention and introduction, the Brunton...

Making a Geologic Cross Section

Source: Laboratory of Alan Lester - University of Colorado Boulder Geologic maps were first made and utilized in Europe, in the mid-to-late 18th century. Ever since, they have been an important part of geological investigations all around the world that strive to understand rock distributions on the surface of the earth, in the subsurface, and their modification through time. A modern geologic map is a data-rich representation of rocks and rock-structures in a two-dimensional plan view. The...
FAQs
Together, the two measurements convert a planar feature’s orientation into information that can be interpreted across a landscape or subsurface. Strike provides the horizontal reference, while dip indicates the direction and steepness of descent. That combination helps show whether layers, faults, fractures, or foliation may guide water movement or influence the behavior of slopes and excavated ground.
Dip direction identifies the side toward which a plane descends, not merely how steep it is. In environmental investigations, that directional relationship helps connect geological orientation with groundwater movement, contaminant transport, and slope behavior. A dip angle without its direction would provide incomplete spatial information for interpreting how subsurface pathways or discontinuities interact with terrain.
Strike and dip are complementary rather than interchangeable measurements. Two planes can share a similar strike yet differ in dip angle or dip direction, producing different three-dimensional orientations. Recording all relevant parts of the measurement therefore distinguishes geological surfaces that may have different effects on water movement, slope stability, excavation conditions, or hazard evaluation.
Field collection centers on observing the planar geological feature and using a geological compass with a clinometer. The compass supplies the directional measurement associated with strike, while the clinometer supplies the angle associated with the plane’s steepest descent. These observations create an orientation record that can support geological mapping and later environmental interpretation.
Strike and dip data show the orientation of layers, faults, fractures, or other discontinuities that may influence subsurface water movement. By relating these orientations to the surrounding geological setting, investigators can assess how water may move through or along planar features. This information supports groundwater-flow assessment and helps interpret subsurface conditions relevant to environmental studies.
The orientation of rock layers and discontinuities can affect how slopes and excavated ground behave. Strike identifies the horizontal alignment of a plane, while dip indicates its descending direction and steepness, allowing investigators to evaluate its relationship with terrain or excavation surfaces. These measurements therefore contribute to slope-stability analysis, excavation assessment, and geological hazard evaluation.
