Coral reefs are among the world's most diverse ecosystems and contribute substantially to ocean productivity and the carbon budget. Disturbances are shifting reefs to altered community states, yet ho...

Small-scale topographic roughness can increase dissipation in seamount wakes by up to tenfold and enhance mixing by a factor of three This effect is most pronounced for seamounts typical of the S...

A collection of honored images from this year’s competition celebrating “photography beneath the surface of the ocean, lakes, rivers and even swimming pools”

The 2nd Ocean Carbon from Space workshop will support progress towards an integrated approach for characterising the ocean carbon cycle using satellite observations and will advance our understanding ...

Nature Microbiology - Environmental micro-compartment genomics provides efficient and high-throughput single-particle DNA sequencing that captures overlooked members of microbial communities.

Most comparative studies assessing reef health focus on living hard coral cover as the key metric. In Indonesia, in situ monitoring of coral cover has been ongoing for over five decades. However, as m...

Fatty acid profiling and stable isotope analysis reveals selective nutrient incorporation in a common mixotrophic reef-building coral. This selective uptake underscores the potential for underestimati...

This study examines the interannual variability in nutrients and phytoplankton in the western North Pacific (WNP) using the eddy-resolving ocean simulation coupled with a biological model. We focus on...

Marine dissolved organic matter (DOM) represents one of Earth's most complex exometabolomes, playing a central role in marine carbon cycling and long-term sequestration. Despite its biogeochemica...

Oxygen is vital for marine life. Despite global ocean deoxygenation, coastal oxygen dynamics are poorly understood. We synthesise the biological and mechanical processes that shape the coastal oxyscap...

The winners of Nature’s 2025 photo competition braved crashing waves and misty mountains to capture their science.

Anthropogenic climate change has precipitated an increase in marine heatwaves (MHWs) that have significant and multifaceted impacts on marine ecosyste…

In 2023–2024, widespread marine heatwaves associated with record ocean temperatures impacted ocean processes, marine species, ecosystems and coastal communities, with economic consequences. Despite warnings, interventions were limited. Proactive strategies are needed for inevitable future events.

Coral reefs are among our planet’s most complex and biodiverse ecosystems and play vital roles in social-ecological systems, but they are also…

The open ocean twilight zone holds most of the global fish biomass but is poorly understood owing to difficulties of measuring subsurface ecosystem processes at scale. We demonstrate that a wide-rangi...

Reliable and standardized ocean temperature monitoring is crucial for advancing our understanding of coral survival and guiding restoration efforts.

We speak to Wally Rich and colleagues about their recent PLOS Climate publication, “Widespread inconsistency in logger deployment methods in coral reef…
