Museum’s 150-Year-Old Plankton Have Thicker Shells Than Their Modern Counterparts

By Theresa Machemer/Smithsonianmag.com

The H.M.S. Challenger spent just over three years in the late 1800s circumnavigating the globe and studying ocean life. Today, thousands of the specimens collected during the Challenger expedition reside at London’s Natural History Museum.

In a new study published in Scientific Reports, researchers at the museum compared plankton collected on the Challenger expedition to modern specimens. They found that on average, today’s plankton has thinner shells than those from 150 years ago—likely as a result of climate change.

The Challenger was a small warship before it was a research vessel. Fifteen of its 17 guns were removed before the mission to make more space on the ship, which was then decked out with rooms for photography, dissections, laboratories and a small library. The Challenger set off in December 1872 with thousands of bottles and boxes for holding specimens and 181 miles of rope to measure the ocean’s depth.

Throughout the journey, the crew would dredge the bottom of the ocean with a weighted net. The net brought up fish, mud and at least one shark. The six scientists aboard the ship documented everything they found, big and small.

  1. The article mention “…They found that on average, today’s plankton have thinner shells than those from 150 years ago—likely as a result of climate change..” Here I had to stop reading that farce from the infiltrated Smithsonian institute. As Carl Sagan used to say: Extraordinary claim requires extraordinary evidences” What is the evidence of the Smithsonian to make such a claim. What scientific methods, involving observation, testing and then formulating hypothesis have they adopted to prove this claim! None, what they did here is simple FRAUD. They have reached their conclusions and then make it up without even bothering with the SCIENTIFIC METHOD! A disgrace! Pure and simple. First they have to prove that global warming – before it was changed to the natural cycle of “climate change” is happening, which they don’t and then connect the effect on the plankton to the global warming which simply is not there. So, the globalists are trying hard. Not even the pictures of flooded land, the natural cycle of ice calving or the white bears swimming for hours (by the way pictures taken during the normal summer thawing of ice shelf) and others will do, they have to try harder in order to get to their aim: the new form of Indulgences called CARBON TAX.

    Carbonic acid is extremely weak acid and outside of laboratory test tubes has a half-life of 26 milliseconds. The oceans are at maximum saturation from over hundred thousand miles of volcanic rift zones to CO2 and there is NO net absorption from the atmosphere. Ocean acidification is another climaclownology FRAUD.

    • Thanks @Joseph Olson. Well said! IT is a FRAUD, based on HOAX and I cannot call their paper s”scientific”, from the globalist UN IPCC, the Smithsonian…. I do not care what credentials these crackpots have, all I am certain is that they had been bought off to sell a big globalist lie. The reasonable people who are entreched to true scientific methods have been vilified and their careers destroyed just for contradicting a non scientific “consensus” . A DISGRACE! I am not going to be impressed by marine or coral reef “endangered” pictures taken in one area just to create fear porn on people akin to the “be worried, be very worried” propaganda. Obviously, the natural cycle makes things to change and it is natural. Things come and go. If these people were objective, they should show real time pictures of both area damaged and thriving areas as one could spot healthy marine area to get an accurate picture of what really happen. But no, all they want is CARBON TAX!
