Nitrous Oxide in the South Pacific: Impacts on Our Oceans

The dynamic chemistry of our oceans is continually influenced by various greenhouse gases, with nitrous oxide (N₂O) being a significant contributor. As a potent greenhouse gas, N₂O not only contributes to climate change but also impacts oceanic nitrogen cycling. This blog explores emerging research on the impacts of nitrous oxide in ocean regions such as […]

The Octopus Bloom of 2025: Unpacking the Surge of Octopuses in UK Waters

In an unexpected twist in marine ecology, 2025 has been declared the ‘Year of the Octopus’ by wildlife organizations across the UK. This statement follows an unprecedented surge in octopus populations off the coasts of Cornwall and Devon. Why 2025 Stands Out The Wildlife Trusts have reported a massive 1500% increase in octopus numbers compared […]

Killer Whales Are Hunting Juvenile Sharks

Two years. Same place. Same outcome. Juvenile great white sharks, about the size of a classroom table, were attacked and killed by killer whales in the Gulf of California. Until recently, scientists believed these interactions were almost unheard of. But new evidence suggests something is changing beneath the surface. And if you work in shark […]

Hidden Ecosystems of the Ordovician

Every fossil story begins with loss. Sediment buries life, time hardens it, and chance decides what survives. For the Ordovician Period—roughly 485 to 444 million years ago—that loss has long been severe. While the Cambrian Explosion left us famous sites like the Burgess Shale, its Ordovician successors seemed strangely quiet. Paleontologists saw only fragments of […]

How AI Could Sharpen Sea Ice Forecasts

Every summer, satellites watch the Arctic Ocean turn from white to blue a little faster. Between 1979 and 2020, the region lost roughly 13% of its summer ice each decade—a shift so dramatic that scientists warn of ice-free Arctic summers by 2050. Forecasting exactly how and when that happens, though, has always been tricky. A […]

A Hidden Network Awakens Beneath Antarctic Seas

Bubbles are rising from the seafloor of Antarctica—and they aren’t just any bubbles. They’re plumes of methane, a greenhouse gas with eighty times the warming power of carbon dioxide over twenty years. Scientists thought such “seeps” were rare in the frozen south. But in a series of startling dives and shipboard surveys, researchers have discovered […]

3 Lessons from Indonesia’s Seagrass Carbon Story

Did you know Indonesia’s underwater seagrass meadows can store more carbon than tropical rainforests? A new study from Pari Island shows how dredging and restoration are reshaping the nation’s “blue carbon” future. 1. Healthy seagrass = carbon gold Persistent seagrass meadows around Pari Island hold up to 234 metric tons of carbon per hectare, far […]

Coral Bleaching Crisis: Implications and Urgent Action Needed

The marine ecosystems along the Western Australian coast are in peril as they experience the worst coral bleaching on record. This alarmingly severe event, driven by an intense and prolonged marine heatwave, has set unprecedented benchmarks in the enduring struggle against climate change and its impact on oceanic biodiversity. Coral Reefs Under Siege The latest […]
