Product Description

K-Pg Boundary Denmark "Dr. Strangelove" Material
After the Chicxulub impact event, about 66 million years ago, it is known that there was a huge drop in the biological activity in the oceans because the sun was largely blocked out thereby reducing photosynthesis in ocean-living algae. Without sun, the algae and the majority of other life would have died off. Without algae (which are at the base of the oceanic food chain) other life forms in the ocean would die off or become extremely rare.

The more widely accepted reconstructions of what happened indicate that this oceanic die-off did indeed occur, and that it took up to three million years for the ecosystems of the open ocean to more fully recover from this impact. (Near-shore ecosystems have been thought to recover much more quickly.) The relatively lifeless post-impact open ocean has acquired a geological term and is now primarily referred to as the “Strangelove Ocean,” in reference to the character in the apocalyptic movie “Dr. Strangelove.”

The "Strangelove Ocean," was first suggested by Dr. Kenneth Hsu, a Swiss scientist, geologist, paleoclimatologist, and oceanographer. Dr. Hsu first presented, in a 1985 paper, information about a catastrophic "Strangelove Ocean" where the carbon cycle had shut down for many thousands of years. The phrase was so vivid that it stuck. There have been scientific papers that debate how long the ocean systems were "dead" and in what proportion. The “Strangelove Ocean” is still used as a technical term in scientific works because it provides a useful model of physical processes in the ocean that continue in the absence of life.

Immediately after the Chicxulub impact, certain areas of the ocean were devoid of oxygen and hostile to most algae, but close to the continent, microbial life was inhibited for a much shorter time than the open oceans. Studies have estimated that the global ocean ecosystem did not return to its former pre-impact status until 1 to 3 million years following the impact.

This specimen is "Dr. Strangelove Material" gathered from the post K-Pg boundary ocean shore, located on private land marking the K-Pg Boundary, in Denmark.
