This region is xknown to be nutrient-poor but supports predator fishes that are central to the economic and food security of the surrounding communities. This conceptual figure shows predator and prey abundance inside and outside of eddies within the North Pacific Subtropical Gyre. “The idea that these eddies contain more food means they’re serving as mobile hotspots in the ocean desert that predators encounter, target and stay in to feed,” said Arostegui. This discovery suggests a fundamental relationship between predator foraging opportunities and the underlying physics of the ocean. The research team was able to investigate predator catch patterns with respect to the eddies, concluding that eddies influence open ocean ecosystems from the bottom to the top of the food chain. warm-blooded).Īlthough there is a growing body of research showing that diverse predators associate with eddies, this is the first study to focus on the subtropical gyre - which is the largest ecosystem on Earth. The research team assessed an ecologically diverse community of predators varying in latitudes, ocean depths, and physiologies (cold vs. It focused on more than 20 years of commercial fishery and satellite data collected from the North Pacific Subtropical Gyre - a vast region that is nutrient-poor but supports predator fishes that are central to the economic and food security of Pacific Islands nations and communities. The study included collaborators from the National Oceanic and Atmospheric Administration’s (NOAA) Pacific Islands Fisheries Science Center. “Increased predator abundance in these eddies is probably driven by predator selection for habitats hosting better feeding opportunities.” Martin Arostegui, WHOI postdoctoral scholar and paper lead-author. “We discovered that anticyclonic eddies - rotating clockwise in the Northern Hemisphere - were associated with increased pelagic predator catch compared with eddies rotating counter-clockwise and regions outside eddies,” said Dr. The findings were published today in Nature. As these anticyclonic eddies move throughout the open ocean, the study suggests that the predators are also moving with them, foraging on the high deep-ocean biomass contained within. Woods Hole, MA – A new study led by scientists at Woods Hole Oceanographic Institution (WHOI) and University of Washington Applied Physics Laboratory (UW APL) finds that marine predators, such as tunas, billfishes and sharks, aggregate in anticyclonic, clockwise-rotating ocean eddies (mobile, coherent bodies of water). We are a concerted threat to legacy media organizations, and proudly so.Woods Hole Oceanographic Institution study suggests relationship between predator foraging and the ocean’s “internal weather” in the North Pacific Subtropical Gyre SanDiegoVille reports fairly on the top entertainment happenings and small businesses doing it right, while not shying away from hard topics and questions you won’t read in local publications where editorial direction is ultimately steered by the sales department. We pound the pavement for our exclusive coverage instead of waiting for permission to break news from the fancy public relations firms that regularly spoon-feed mainstream media sources their story ideas, influencing journalists’ opinions with freebies and fanfare. We are a different kind of news site with no desire to conform to antiquated ideas of how many believe journalism should be. SanDiegoVille was created in 2010 to report about all the fun & delicious happenings taking place around America's Finest City and we quickly earned a reputation for being a news source for and by those that shun archaic journalistic practices in pursuit of reporting the real story.
