Waters West of Europe Drive Ocean Overturning

across the entire North Atlantic over the 21-month study period.These findings can help scientists better predict what changes might occur to the MOC and what the climate impacts of those changes will be, said Susan Lozier, the Ronie-Rochele Garcia-Johnson Professor of Earth and Ocean Sciences at Duke University’s Nicholas School of the Environment and adjunct scientist at the Woods Hole Oceanographic Institution (WHOI).“To aid predictions of climate in the years and decades ahead, we need to know where this deep overturning is currently taking place and what is causing it to vary,&rdquo

scientist, government official, and director for several corporate and non-profit organizationsEarning undergraduate and post graduate degrees in botany helped form Dr. Earle’s belief that understanding vegetation was the first step in understanding any ecosystem. Dr. Earle’s 1966 Duke University dissertation, “Phaeophyta of Eastern Gulf of Mexico,” shed new light on the region’s aquatic plant life, and when combined with her other Gulf research, the body of work stands today as the definitive study of the region’s abundant and rich aquatic plant life.Dr. Earle

; Before joining NOAA Fisheries in 2002, Pentony worked for five years as a policy analyst for the New England Fishery Management Council, primarily on issues related to habitat, marine protected areas, and the deep-sea red crab fishery.   He has a Bachelor of Science in Engineering from Duke University in North Carolina, and a Master’s of Environmental Management from the Nicholas School of the Environment at Duke University. Between college and graduate school, Pentony served for six years as an officer in the U.S. Air Force as an engineering project manager on a variety of military

The study also found the price of small shrimp went down and the price of large shrimp increased, which led to short-term economic ripples in the Gulf brown shrimp fishery.    A team of scientists led by Louisiana State University and the Louisiana Universities Marine Consortium

Duke Receives Funding for New Research Vessel

 Duke University said it has received $11 million for the construction and operation of a new state-of-the-art vessel that will expand teaching and research capabilities at its marine lab.   The gift to the Nicholas School of the Environment from the Grainger Family Descendants Fund, a donor-advised fund at The Chicago Community Trust, provides $5 million to build the new 68-foot oceangoing research vessel and an additional $6 million to support operating costs.   The ship will have wet labs and dry labs, oceanographic equipment, a galley and sleeping quarters. It will be an oceangoin

The resulting low oxygen levels are insufficient to support most marine life and habitats in near-bottom waters, threatening the Gulf’s fisheries.   The Gulf dead zone may also slow shrimp growth, leading to fewer large shrimp, according to a NOAA-funded study led by Duke University. This could mean higher costs of large shrimp at the marketplace and an economic ripple effect on the Gulf shrimp fisheries.   “The Gulf’s summer hypoxic zone continues to put important habitats and valuable fisheries under intense stress,” said Rob Magnien, director

Scientists think that American eels spawn somewhere in the southwest corner of the Sargasso Sea, which is surrounded by circulating ocean currents. The eels migrate as tiny larvae to fresh waters along the coast, where they spend their adult lives. Where the adults spawn and how the larvae migrate to the coast both remain mysteries.

Perhaps some overlooked biological features were key factors that allowed larvae to reach the coast?    The team enlisted a fourth member, physical oceanographer Suzan Lozier of Duke University, and created a computer model that incorporated a range of biological and oceanographic data to simulate the larvae’s travel patterns.    “We used these models that essentially have the ocean currents in them,” Llopiz said. “We released the virtual larvae
