I’ve always been suspicious of the rubber sheet explanation for gravity. It was tautological, explaining gravity through gravity. Just didn’t make a lot of sense. Now this explanation actually does:
Shock Waves on Tavurvur – Volcano Monday
The shock wave on the Tavurvur volcano in Papua New Guinea is really quite impressive!
A geologic mystery solved! – The sailing stones
When you write about geology you inevitably come across a couple mysteries that are just unsolved. In the Racetrack Playa in Death Valley they have many names for this phenomenon. Racing Rocks Sailing Stones Wandering Stone Moving Stones In the end they were just as puzzling. These rocks were moving without any apparent force moving […]
Miles vs Kilometer – Easy conversion with Fibonacci
Measurements are important. Even the little one’s want to know how much they grew in the past month. It’s a frame of reference. However, especially in geophysics we have not agreed on the same frame of reference. When you look at your data, you better make sure if it’s meters or feet or miles. It’s […]
The Showroom – Data for my thesis
I’m working on a field data set from the Mediterranean Sea. There are many intellectual reasons for working this data set. However, there are some motivate my inner child as well, let me explain. The Specs The data set was recorded by TGS and is of brilliant quality. Almost 8km (5mi) in offset over the […]
The end is near! – My Master Thesis
I just started the end of my journey in university. I registered my Master’s thesis. This feels like quite the step and I’m very proud I’ve come so far. Today I start the last chapter of my studies. In half a year's time I'll finish my Master's. Exciting times lie ahead. — Jesper Dramsch (@JesperDramsch) […]
Gain traction in the Geoscience community
The internet is a wonderful place. I am one of the lucky people who does not have to wait for weeks to get a hold of a paper I might need for my thesis. As a scientist this international network has become indispensible. Not just for retrieving papers, but also the review process and colaboration. […]
Cloud Chambers
At the moment I am working on my Master’s thesis. As this is taking up a lot of my resources, I fail at generating more content for this blog. Geophysics related writing goes into the thesis right now. However, I’ve written a short piece on visualizing radioaktive decay in a diffusion cloud chamber. It’s not […]
Quadcopters and Volcanoes = awesome!
Today’s volcano is featured by a quadcopter. Be sure to check out this amazing footage! from Tumblr
Do you know your seismic velocity?
In seismic data analysis a lot of work goes towards getting a good velocity model of the subsurface. We talk about the seismic velocity. However, this may lead to some serious misconceptions. One step in seismic processing is velocity analysis. We pick the velocity that adjusts our data for the best value. Usually this is […]
