You are taught early in science that oxygen on Earth comes from sunlight. Plants, algae, and cyanobacteria use light to split water and release oxygen, shaping the atmosphere and making complex life ...

A groundbreaking discovery reveals oxygen production in the ocean's depths, challenging our understanding of Earth's ...

In the last 50 years, oxygen-deficient zones in the open ocean have increased. Scientists have attributed this development to rising global temperatures: Less oxygen dissolves in warmer water, and the ...

The effects of the steadily increasing amount of plastic in the ocean are complex and not yet fully understood. Scientists at GEOMAR Helmholtz Centre for Ocean Research Kiel have now shown for the ...

A new study published in the journal Nature Geoscience found evidence of oxygen production near polymetallic nodules located deep in the ocean. Called dark oxygen, this oxygen is being produced ...

Extensive sea ice covered the world's oceans during the last ice age, which prevented oxygen from penetrating into the deep ocean waters, complicating the relationship between oxygen and carbon.

Oxygen has been historically linked to sunlight. But a new study has suggested that oxygen may also be produced without any sunlight at all. Scientists at the University of Southern Denmark recently ...

Chinese scientists have recently developed a novel method for measuring dissolved oxygen (DO) levels in the ocean and a new dataset for monitoring dissolved oxygen concentration (DOC) of global oceans ...

Oxygen is vital for life on Earth, and is mainly produced by plants, algae and cyanobacteria via photosynthesis. A few microbes are known to make oxygen without sunlight, but so far they have only ...

The effects of the steadily increasing amount of plastic in the ocean are complex and not yet fully understood. Scientists have now shown for the first time that the uptake of microplastics by ...
