Data in support of Supplement to 'Regionally disparate ecological responses to microplastic slowing of faecal pellets yields coherent carbon cycle response'
AI summary Read the abstract
This is a data repository record containing model code and output files supporting a published study on how microplastics slow the sinking of zooplankton fecal pellets, which affects how carbon moves from ocean surface waters to the deep sea. The associated study found that even when ecological responses varied by region, the overall effect on the ocean carbon cycle was consistent.

This is a data repository record containing model code supporting a study on how microplastics slow the sinking speed of zooplankton fecal pellets in the ocean, affecting carbon export to the deep sea. The study's ocean circulation model simulated how this slowing effect varies by marine region.

Regionally disparate ecological responses to microplastic slowing of faecal pellets yields coherent carbon cycle response
AI summary Read the abstract
This study modeled how microplastics slow the sinking of zooplankton fecal pellets and found that, despite regional variation in the ecological response, the net effect on the ocean carbon pump is a coherent reduction in carbon export to the deep ocean across different ocean regions.
Microplastics disrupt Antarctic krill faecal carbon export_updated
AI summary Read the abstract
This entry is the code and raw dataset accompanying a scientific paper on how microplastics affect Antarctic krill's ability to produce dense, sinking fecal pellets that carry carbon to the deep ocean. The underlying research found that microplastic ingestion causes krill to produce smaller, more fragile pellets that sink more slowly, potentially reducing the Southern Ocean's biological carbon pump. It is the data repository record rather than the published paper itself.
Modeling the Vertical Transport of Copepod Fecal Particles under Nano/Microplastic Exposure
AI summary Read the abstract
Researchers studied how nano- and microplastics affect the fecal pellets produced by tiny marine copepods, which play a crucial role in transporting carbon from the ocean surface to deeper waters. They found that plastic particles reduced both the size and production rate of fecal pellets, and a fluid dynamics model showed this would slow their sinking speed and reduce vertical carbon transport. The study suggests that widespread microplastic pollution could interfere with the ocean's ability to sequester carbon.
