What this story says
- The Great Pacific Garbage Patch has become significantly bluer and greener over the past two decades, according to satellite data.
- Scientists from the University of Bergen suggest microplastic pollution may be responsible for the observed color change.
- Simulations indicated that microplastics increase the likelihood of the water appearing cyan, a color detected by satellites.
- Researchers acknowledge that direct measurements within the Garbage Patch are necessary to confirm plastics as the sole cause.

The water in the Great Pacific Garbage Patch has become noticeably bluer and greener over the last 20 years, as indicated by satellite data analyzed between 2002 and 2022. Scientists from the University of Bergen in Norway conducted a study, published in the journal Communications Earth & Environment, suggesting that microplastic pollution may be altering the ocean's color. The researchers analyzed satellite imagery and ran simulations to understand the phenomenon.
Disagreement on certainty of cause
While the study's findings point to microplastics as a likely cause for the color shift, researchers acknowledge that further direct measurements are needed to definitively prove plastics are the sole reason. The simulations showed that microplastics increase the probability of the water changing to a cyan color, a hue detected by satellites. However, the scientists noted that other factors, such as phytoplankton, could also influence ocean color. Direct measurements in the Garbage Patch are described as a tricky and expensive next step to verify the findings.
What the coverage left out
None of the left-rated digests or full reports mentioned the specific journal where the study was published. The right-rated digest did not mention the journal or the specific researchers involved in the study.

- Both left-rated reports highlighted the study's suggestion that microplastics are changing the ocean's color. Scientific American stated that the "ocean's blue and green hues near the infamous zone of debris have gotten brighter over the past 20 years, satellite data show." It also quoted a study author saying, "We’re still one step away from proving definitively that microplastics are causing the shift in color that that we’re seeing." NBC News reported that "Microplastics appear to be changing the color of the ocean around the Great Pacific Garbage Patch, new research reveals, a shift satellites can see from space."

- Centre-rated reports focused on the observed color change and the potential link to microplastics. Multiple digests, including those from KIFI, KRDO, KVIA, KEYT, KESQ, KMIZ, and Science Alert, stated that the Great Pacific Garbage Patch has become significantly bluer and greener over two decades, with scientists discovering increasing plastic pollution as a possible reason. KIFI's full report noted that the color of the ocean reflects what is in it, from phytoplankton to marine debris, and that a "gap" existed in research on how microplastics affect ocean color. Science Alert described the garbage patch as a "growing behemoth of humanity's creation."

- The single right-rated report, a digest from WPSD Local 6, stated that the Great Pacific Garbage Patch may now have so much plastic that it is changing the color of the ocean. It reported that a wide patch of water between Hawaii and California has been changing color over the past two decades, becoming significantly bluer and greener.
Questions about this coverage
- How did the left and right cover Microplastics May Be Changing Great Pacific Garbage Patch Color?
- Of the 11 outlets on this story carrying a published leaning rating, 27% are rated left, 64% are rated centre, 9% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it. The sections above set out what each side emphasised, in its own terms.
- Is Microplastics May Be Changing Great Pacific Garbage Patch Color left or right?
- Too few of the outlets on this story carry a published leaning rating to say. 11 of them do, and this site does not characterise a field under 12: at that size one newsroom filing moves the share by ten points. The percentages above are the count as it stands.
- Is the coverage of Microplastics May Be Changing Great Pacific Garbage Patch Color biased?
- Microplastics May Be Changing Great Pacific Garbage Patch Color is one event reported by 11 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
- Which outlets covered Microplastics May Be Changing Great Pacific Garbage Patch Color?
- 11 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
- What has happened to the Great Pacific Garbage Patch's color?
- Satellite data analyzed between 2002 and 2022 shows that the Great Pacific Garbage Patch has become significantly bluer and greener over the past two decades. This change in hue has been detected from space.
- What is the suspected cause of the color change?
- Scientists from the University of Bergen suggest that microplastic pollution may be responsible for altering the ocean's color. Their simulations indicated that microplastics increase the likelihood of the water appearing cyan, a color observed in satellite data.
- Is it definitively proven that plastics are changing the ocean's color?
- No, researchers acknowledge that further direct measurements within the Garbage Patch are needed to definitively prove that plastics are the sole cause of the color change. While simulations support the hypothesis, other factors could also be involved.
