Whale sharks, the world's largest fish, roam less than previously thought. This new study, published in the journal Marine Ecology Progress Series, used stable isotope analysis to demonstrate that whale sharks feeding at three disparate sites in the Western Indian Ocean and Arabian Gulf rarely swim more than a few hundred kilometres north or south from these areas according to researchers from the Marine Megafauna Foundation, University of Southampton, and Sharkwatch Arabia.
The Global Precipitation Measurement mission or GPM core observatory satellite provided very good coverage of hurricane John when it passed above the eye of the tropical cyclone on Aug. 8, 2018. GPM found heavy rainfall within the large hurricane.
Researchers with the State of Hawai'i Division of Aquatic Resources (DAR) and the Hawai'i Institute of Marine Biology (HIMB) at the University of Hawai'i at Mānoa found a management approach that combining manual removal and outplanting native urchin was effective at reducing invasive, reef smothering macroalgae by 85 percent on a coral reef off O'ahu, Hawai'i.
Tropical Storm Yagi was experiencing wind shear when NASA's Terra satellite passed over the Northwestern Pacific Ocean and analyzed the storm.
NASA-NOAA's Suomi NPP satellite caught up with Typhoon Shanahan and provided forecasters with a visible picture of the storm on Aug. 8. The satellite image revealed the storm still maintained an eye, although now cloud-filled.
Hurricane Hector maintained its major hurricane status on Aug. 8 as NASA's Aqua satellite passed overhead. Infrared data from NASA's Aqua satellite provided forecasters with cloud top temperatures in Hector so they could pinpoint the strongest part of the storm.
Fishing fleets operating outside of national waters contribute less than 3 percent to the world's seafood supply. This finding goes against the common assertion that high seas fisheries are important for food security.
NASA's Aqua satellite passed over the Central Atlantic Ocean and looked at cloud top temperatures in Debby, revealing the storm had transitioned from subtropical to tropical.
In August a team of scientists is sailing 200 miles to the northeastern Pacific Ocean with advanced robotics and other instruments on a month-long quest to investigate plankton and their impact on the carbon cycle.
Hundreds of thousands of sharks, sea birds and other marine species are accidentally killed each year after becoming snagged or entangled in longline fishing gear. Models developed by a Duke-led research team may help reduce the threat by giving regulatory agencies a new tool to predict the month-by-month movements of longline fleets on the high seas and determine where and when by-catch risks are greatest.
