Overview To create your Field Data Interpretation Reports and the Geophysical Portfolio we will created in LaTeXt use=ing Overleaf, an online LaTeX editor, and the bibliography and references manager Zotero. Reference and bibliography managers are great; they allow you to store references in a uniform format that can then be rendered in the style of whatever journal you like, from the Journal of Geology to the Slovenian Journal of Mineralogy and far beyond 😉. :::success Sign up for a free Overleaf account using an email address (it can be but does not need to be be your Cal Poly email, and you can always change the email associated with your account anytime you like.)

Types of Earthquake Waves Earthquakes generate two types of waves: P-waves and S-waves. P-waves P-waves are called compressional waves Have the fastest velocity, so they arrive first to a seismometer. P-waves travel at about 5.8 km/s in the mid-continental crust (i.e. as about 20 km depth). P-waves has smaller amplitude than S-waves, and shake the surface of the earth (e.g. your house) primarily in the vertical direction P-waves deform the material they travel through parallel to the direction the wave is moving - see GIF below:

Iteration of Complex-valued Functions The mathematical field of dynamics is even more broad than only complex dynamics but that's about all I can say about that. History of Complex Dynamics There are several books and articles on the history of complex dynamics: Book: Early Days in Complex Dynamics: A history of complex dynamics in one variable during 1906–1942 Book: A History of Complex Dynamics From Schröder to Fatou and Julia A Century of Complex Dynamics. I don't know if this article was published elsewhere or not, but this pdf is freely available.

GEOL 301/303 F23/W24 Introduction This topic follows the material on seismic tomography because we use the seismic tomography image of a mantle plume beneath the west Antarctic Seroussi et al., 2017 to think about delivery of thermal energy to base of the lithosphere. However to keep it simple, we will think of the heat energy as being delivered to the base of the Antarctic crust. Below is the tomography figure from Seroussi, 2017: image The A-A' cross section, with the red spot on figure panel (b), is where observations of metling processes have been made.

Geophysical data collection using a large variety of methods. Their name is a little misleading in that they work in many other areas besides hydrological applications. Quantec Geoscience. Specializing in the magnetotelluric (MT) method. The MT method collects resistivity data, but has an advantage of being able to collect very deep data (several kilometers, and even much more). The tradeoff is of course lower resolution.

Here is a link to the Geophysical Portfolio guidelines. All the relevant data sets will shortly be linked to below by "chapter": Data CH 1 - Chorro Creek Remember that the "Reference Profile" is define as: 28 electrodes @ 2m with E1 at 35.339390 , -120.768990 and a heading from E1 to E28 of 340 degrees. Chorro Creek Exploratory Boreholes Report by Cleath-Harris Geologists. This is very exciting to have 😃 1D VES data and field notes.

Fall 2022 1. Chorro Creek Dog Leg Reference Profile Geophysical Surveys The Chorro Creek Dog Leg Reference Profile (CCDL-RP) is defined as an electrical resistivty profile: 28 electrodes at 2-meter spacing (54 meters total) Electrode 1 (E1) at coordinate (35.339390,-120.768990) From E1 to E28 follow a strike of $340^{\circ}$ Array style is variable. Other geophysical surveys (even non-electrical) that are not this exact length can then be referenced to this.
