Sargassum Now World’s Largest Harmful Algal Bloom Due to Nitrogen Details
Share This
Because of anthropogenic emissions of oxides of nitrogen (NOx), the NOx deposition rate is about five-fold greater than that of pre-industrial times largely due to energy production and biomass burning.
For centuries, pelagic Sargassum, floating brown seaweed, have grown in low nutrient waters of the North Atlantic Ocean, supported by natural nutrient sources like excretions from fishes and invertebrates, upwelling and nitrogen fixation. Using a unique historical baseline from the 1980s and comparing it to samples collected since 2010, researchers from Florida Atlantic University’s Harbor Branch Oceanographic Institute and collaborators have discovered dramatic changes in the chemistry and composition of Sargassum, transforming this vibrant living organism into a toxic “dead zone.”
Digitizing the dead: Cemetery project puts graves on the map

MONROE, La. (AP) It’s surprisingly easy to end up in an unmarked grave, even buried in a city cemetery.
David Holt, an associate professor of geography at the University of Southern Mississippi, pointed at an orange flag next to a pink plastic flower stuck in the ground on the afternoon of May 15 at Hasley Cemetery in West Monroe.
“You can see how easy to lose where that flower is,” he said. “It’s not like a metal marker, you could lose those too. They rust over time, or the lawnmower hits it once, off it goes. They’re trained not to do that, but they get older and older and older. That flower, it’s going to be an unmarked grave in a handful of years.”

A geography professor at The University of Southern Mississippi (USM) Gulf Park in Long Beach and six of his students are engaged in a project collecting information about a historic Louisiana city cemetery, using the latest technology featuring geographic information systems (GIS) and ground penetrating radar (GPR).
Dr. David Holt, along with undergraduates Candice Pellier and Angela Slawson, and graduate students Lloyd Dedeaux, Alyssa Crowell, David Duvall and Ian Stewart, traveled May 14-15 to West Monroe to conduct a remapping and coding of Hasley Cemetery, located
