Plankton Modelling Revolution Urgently Needed to Safeguard Future Climate Predictions

Marine researchers from the University of Exeter and Plymouth Marine Laboratory emphasize that outdated plankton models threaten our ability to predict and address global climate change impacts. Plankton, vital microscopic organisms, are crucial for carbon cycling, marine productivity, and Earth's climate stability. However, current models oversimplify their diversity, using decades-old concepts. The study insists on a radical update of these models, incorporating modern biology and collaboration between researchers and

Study Discovers That “Marine Snow” Keeps the Ocean Alive

Oceanographers have long recognized sunlight, currents, and tides as key drivers of sea life—but new research reveals a humble yet crucial contributor: “marine snow.” These tiny, drifting particles of organic debris serve as hotspots for specialized bacteria that perform nitrogen fixation, converting inert N₂ gas into biologically usable forms and sustaining life in the water column.

Planet’s Darkening Oceans Threaten Marine Life

Great swathes of the world’s oceans have become significantly darker over the past two decades, shrinking the critical photic zone where the majority of marine life thrives, a new study warns. Researchers used satellite data and advanced modelling to reveal that between 2003 and 2022 more than one-fifth of the global ocean has lost enough light penetration to push its photic zone shallower by at least 50 metres in some regions.

Rising Temperatures and Ocean Acidification Threaten Marine Life, New Study Warns

A recent study conducted by marine biologists at Stanford University has raised alarming concerns about the combined impact of rising ocean temperatures and increasing acidification on marine ecosystems. The study, published in Nature Climate Change, warns that the rapid changes in ocean chemistry could lead to significant disruptions in the food chain, affecting marine life from the smallest plankton to the largest predators.
