ABy Thomas Wolcott, North Carolina State University; Donna Wolcott, North Carolina State University; John L. Largier, University of California, Davis, and Steven G. Morgan, University of California, Davis. Many people who love the oceans never realize that a single drop of seawater is teeming with plankton, which means “drifters” in Greek. These organisms, which typically

As climate change alters the oceans, what will happen to Dungeness crabs?

By Paul McElhany, National Oceanic and Atmospheric Administration. Many travelers visit the Pacific Northwest to eat the region’s famous seafood – particularly Dungeness crabs, which are popular in crab cakes or wrestled straight out of the shell. Locals also love catching and eating the feisty creatures. One of my favorite ways to spend an afternoon

There are bright spots among the world’s coral reefs – the challenge is to learn from them

By Joshua Cinner, James Cook University. Despite substantial conservation efforts, human impacts are harming coral reefs all over the world. That in turn affects the millions of people who depend on reefs for their livelihoods. It’s a gloomy picture, but there are some bright spots. In a study that appears on the cover of this

Solving ‘Darwin’s Paradox’: why coral island hotspots exist in an oceanic desert

Andrew Frederick Johnson, University of California, San Diego It was Charles Darwin, almost 200 years ago, who first asked how it could be that coral reefs could flourish in relatively barren parts of the Pacific Ocean. This conundrum subsequently became known as Darwin’s Paradox. A study published this week in Nature Communications helps answer just

Far more microplastics floating in oceans than thought

Kara Lavender Law, Sea Education Association and Erik van Sebille, Imperial College London Plastic pollution in the ocean frequently appears as seabird guts filled with cigarette lighters and bottle caps, marine mammals entangled in fishing gear and drifting plastic bags mimicking a gelatinous meal. Last year, a study estimated that around eight million metric tons

Oceanic Researchers Find Deep Hydrothermal Vents Made of Something Completely Different

Normally, deep ocean hydrothermal vents are made of sulphide minerals, but in strange twist, oceanic researchers from the University of Southampton have found vents in the Caribbean that are unlike anything that has been discovered before. These vents are made of talc. Researchers analyzed samples from active vents in the Von Damm Vent Field (VDVF), a
