Planet’s ocean-plastics problem detailed in 60-year data set
Researchers find evidence of rising plastic pollution in an accidental source: log books for planktonmonitoring instruments. Matthew Warren
Scientists have uncovered the first strong evidence that the amount of plastic polluting the oceans has risen vastly in recent decades — by analysing 60 years of log books for plankton-tracking vessels.
Data recorded by instruments known as continuous plankton recorders (CPRs) — which ships have collectively towed millions of kilometres across the Atlantic Ocean — show that the trackers have become entangled in large plastic objects, such as bags and fishing lines, roughly three times more often since 2000 than in preceding decades.
This is the first time that researchers have demonstrated the rise in ocean plastics using a single, longterm data set, says Erik van Sebille, an oceanographer at Utrecht University in the Netherlands. “I’m excited that this has been finally done,” he says. The analysis was published on 16 April in Nature Communications.
Although the findings are unsurprising, long-term data on ocean plastics had been scant: previous studies looked mainly at the ingestion of plastic by sea creatures over shorter timescales, the researchers say.
Fishing for data
CPRs are torpedo-like devices that have been used since 1931 to survey plankton populations, by filtering the organisms from the water using bands of silk. Today, volunteer ships such as ferries and container ships tow a fleet of CPRs around the world’s oceans.
(…)Each time a ship tows a CPR, the crew fills in a log book and notes any problems with the device. So Ostle and her colleagues looked through all tow logs from the North Atlantic between 1957 and 2016, to determine whether plastic entanglements have become more common.
Evidence analysis
(…)Van Sebille says that because the study focused on large plastic items, it doesn’t reveal much about the quantity of microplastics — fragments fewer than 5 millimetres long — in the oceans. These tiny contaminants come from sources such as disposable plastic packaging, rather than from fishing gear.
Nevertheless, he adds, the study demonstrates that fisheries play a major part in plastic pollution, and will provide useful baseline data for tracking whether policy changes affect the levels of plastic in the oceans. “As fisheries become more professional, especially in the North Sea, hopefully we might see a decrease,” he says.

Brazil corruption scandals: All you need to know
For the past three years, Brazil has been gripped by a scandal which started with a state-owned oil company and grew to encapsulate people at the very top of business - and even presidents.
On the face of it, it is a straightforward corruption scandal - albeit one involving millions of dollars in kickbacks and more than 80 politicians and members of the business elite.
But as the tentacles of the investigation dubbed Operation Car Wash fanned out, other scandals emerged.
It has led to some of those who have found themselves accused claiming they are the victims of political plots, designed to bar them from office.
What is Operation Car Wash?
Operation Car Wash began in March 2014 as an investigation into allegations that Brazil's biggest construction firms overcharged state-oil company Petrobras for building contracts.
Investigators accused directors at the firm - named the world's most ethical oil and gas company in 2008 - of skimming the extra money off the top as a bribe for awarding the contract.
Which is bad enough - but then the Workers' Party found itself dragged into the corruption scandal amid allegations of having funneled some of these funds to pay off politicians and buy their votes and help with political campaigns.
Among those accused in the scandal were dozens of politicians, and Luiz Inacio Lula da Silva - the country's extremely popular former president, known affectionately as "Lula".
