I was mainly going off this. David Johns, head of the Continuous Plankton Recorder Survey, describes it as "a literal drop in the ocean." Johns would know—the Continuous Plankton Recorder Survey has been running since 1958 and has accumulated more than 265,000 samples. The Continuous Plankton Survey has indeed cataloged a loss of plankton over the years—but nothing close to the 90 percent loss claimed by Dryden. "We have noticed long-term changes—northerly movements of plankton species as surface water warms, changes in seasonality in some taxa, invasives, etc.," Johns told Ars by email

Well johns’ framing is poor. Or at least the blogger’s presentation of it is. The drop in the ocean comment is wrong. That’s not how stats works. You may want to argue that your samples have superior collection methods, but don’t attack the size. What’s worse, as far as I can tell the actual preprint doesn’t make the 90% claim. It’s referring to the risk of loss from ocean acidification in the next 20 years. As far as I can tell it’s just bad science naive bloggers and journalists all around plus armchair experts criticizing each other. If anyone is going to talk about skepticism and scientific literacy, step one should be ignoring pop summaries in the news. https://deliverypdf.ssrn.com/delivery.php?ID=327083003119119021018031110024026107026015032006043044006100065007099118090003116065017028043099109098119077067082103110094121024055038007038115100123112112064098095010081020002014091000070125111100115118093000030119093014026074126004081025022113102123&EXT=pdf&INDEX=TRUE https://deliverypdf.ssrn.com/delivery.php?ID=327083003119119...
