The Salty Sea Part III: Are the Oceans Getting Saltier Over Time?

The Salty Sea Part II: A Young Earth Salt Chronometer?
In Part I of this series I looked briefly at some recent encounters in which the salty sea is being discussed as a chronometer of sorts for determining the age of the earth. But how is this salt chronometer actually claimed to work? An article from ICR entitled, The Ocean’s Salt Clock Shows a Young World and includes the following:
Diverse Geological Landscapes Found on Mars
Curiosity has beamed back some really remarkable images from Mars in the past couple of days. The site for its landing was chosen because it appeared from satellite images that there was layered rock and some diversity of chemical signatures at different elevations but the pictures taken from ground level reveal a more spectacular and...

The Salty Sea and the Age of the Earth, Part I – Confirmation Bias
According to young earth creationists, there isn't enough salt in the oceans if the earth is old. Recent references to this argument have spurred me to look a little closer at how it is being used today. What I find is that it appears to have only a purely rhetorical use as the actual data about the ocean'salinity suggests that the amount of salt in the sea is a useless tool for indicating the earth is old or young.
The Mars Curiosity Rover: A Geological History Detective
How could anyone not be curious about Mars Curiosity rover? NASA gambled by playing up the "7 minutes of terror" landing, using social media very adeptly to get a huge audience right in the middle of the Olympics. Failure of the rover to safely land surely would have been a crushing blow to the... Continue Reading →
Geological Context II: Neanderthals and the Italian Supervolcano
There are thousands of sites with either human remains or artifacts (stone tools usually) that are known across southern Europe and many are found in locations where they are found in layers stacked on top of each other like in caves or flood plain locations along rivers. But, the exact pattern of Neanderthal and modern human population migrations and changes is not my main interest.
The Frequently Overlooked Geological Context of Hominid Fossils
The human fossil record is probably one of these least understood yet frequently discussed topics in the Christian church. I have neither the expertise nor the desire to attempt to resolve the debate over whether particular fossils represent human ancestors or not. I understand that human origins is a sensitive topic, especially within the conservative evangelical church... Continue Reading →
Psalm 104 – Evidence of Post-Flood Plate Tectonics?
For some time I had been planning to write about the use of Psalm 104 in creationists circles as evidence for a physical description for tectonic events following a world-wide flood. Specifically, versus six through nine of Psalm 104 have been suggested to be not a reflection on creation, as is the traditional reading, but... Continue Reading →
Doggerland: The Ice Age, Sea Level Rise, and Human Migration
Update Feb 2014: I have rewritten this article with updated information here: Fishing For Fossils in the North Sea: The Lost World of Doggerland You may have seen reports of the discovery of the "British Atlantis" circulating the web. Those stories seem to have been sparked by a new display of recent research at... Continue Reading →
Fossil Field Trip: Fossil Reefs Under the Feet of the PCA GA
On my trip to Kentucky this week to attend the PCA GA I took some time to do some geological sightseeing. I hope I can convince you that it was a lot more exciting that it might sound:-) Below are some pictures I took at two locations. The first are from the Falls of... Continue Reading →
Reflections on the PCA GA and the Age of the Earth Seminar
The PCA (Presbyterian Church of America) General Assembly includes a number of seminars on a wide variety of topics each year. This year one talk received considerable attention prior to the meeting because of the subject matter and the presenter. I made the 6 hour drive to Louisville, KY to hear the talk as...

Adam and The Fall: A Thorny Young Earth Assumption
My WordPress tag reader led me to this video posted on Eric Hovind's "Creation Today" website. This site is what Dr Dino's website presence morphed into after the arrest and conviction of fringe creation scientists Kent Hovind. What caught my eye was that today's video highlighted evidence of creation from thorns. I have been thinking... Continue Reading →
Long Distance Dispersal via Catastrophic Events
When I give my lecture in class about animal distributions, questions often are raised about how did animals get to some remote islands or even islands that are not that far off from the mainland. Sometimes the answer is that during ice ages the oceans was up to hundreds of meters lower than it is... Continue Reading →
As The Asteroid Tumbles: Asteroids and the Age of the Solar System
There are millions of asteroids orbiting the solar system most of which are found in the asteroid belt between Mars and Jupiter. Studies of these asteroids, as part of an effort to assess the threats to earth, have allowed us to track and paths, sizes and rotational frequencies of over 1000 asteroids.
