Don't Panic Geocast

This week we discuss how geoscience can enrich anyone’s life. Join the discussion and then learn about how much cosmic dust falls on us every day! John was on The Orbital Mechanics Episode 24 talking about SMAP. Why Learn Geology Your World Rocked (Slate) Spatial thinking/reasoning Thinking in 3D is hard… 4D is harder 3D Mouse Resources We need resources for our modern lifestyle Earth is continuously changing (as pointed out in the article), so preserving it as is should NOT be the goal, but preserving a habitable planet. Place based knowledge Connects you directly to the land. Everyone has a “place” and by further exploring it through geology it can create a deeper connection. Time “Any good intro geology course is actually a course in time” Geologic time…it’s really big! Pale Blue Dot Photo Puts things in perspective. Carl Sagan’s Pale Blue Dot commentary does a great job of showing spatial and temporal smallness. It doesn’t make you feel small though, it makes you feel free. Chokes me up every t

Join us to talk about the Earth’s magnetic field. It protects us and has complication on more levels than you think. It produces the aurora and helps us date rocks and structures!

This week we thought we would go through our every day carry (EDC) essentials for braving the academic jungle. As most of us go back to the academic year, it’s important to fine tune what we carry to do our job anywhere.

Classes are back in session, and we’re back to normal episodes. Join us to talk about Brunton pocket transits, argue about strike and dip, and discuss the zombie apocalypse. AAPG abstracts are due September 24! Windows 10 isn’t supporting external USB microphones right now. What? Checkout Angie’s beautiful photos. Part 1 Part 2 What is a Brunton? A compass, but a really expensive one with lots of features Generally referring to the conventional pocket transit About the size of a deck of cards, but worth $500 It’s a very accurate compass/clinometer combination that we use to take strike and dip measurements amongst others Can also sight bearings to objections or angle from horizontal by using the sights and mirror Can set the magnetic declination. Just don’t forget! Strike and Dip Two numbers that define the orientation of a plane in 3-dimensional space using an agreed upon handedness convention Dip direction is the direction water would run if poured on the rock, angle is how steep that rock is inclined

Intro The Orbital Mechanics highlighted how little we know about planetary formation, so let’s talk about Pluto and what we’ve learned from the New Horizons Mission. Pluto Basics Officially a dwarf planet in the Kuiper belt About 0.18 the radius of Earth Mass 0.178 of the moon’s Very low density Gravity 0.63 g Neptune and Pluto were both predicted to exist from orbital perturbations of Uranus Percival Lowell (founder of Lowell observatory) started the hunt for pluto in 1906. Tombaugh found Pluto using a blink comparison technique Moons of Pluto Orbit is chaotic, we can predict forwards and backwards for several million years, but over the Lyapunov time we have no idea.

This week we get ready for conference abstract deadlines and talk about how we prepare abstracts. Everyone is finally back in town, but not for long! Pluto show next week! Abstract deadlines: AGU 8/5, GSA 8/11 GSA, new topical abstracts (search visually by emoji!) How we prepare to write abstracts Choosing the topical material. When do you stop reporting on research?* Think about what session to submit to Mind maps Outlines Stream of conscience writing Abstract Madlibs Don’t do this steps hours before it is due. Leave days to mull it over How preliminary is your data? Is it ready for an abstract? Writing the abstract Check the conference guidelines… then check them again. Open an editor. John uses plain text editors initially. Send it around for others to look at Decide on authorship early Tools for collaborating (a whole other show) Google docs Word/dropbox Evernote (although everyone involved needs premium) Email… if you do this, please don’t admit it Other Notes AGU offering free conference regist
