The instrument was deployed on NOAA’s research vesselRon Brown in collaboration with scientists from NOAA’sEarth System Research Laboratory. Ozone flux data wereobtained for a total of 7 weeks in 2006, covering more than1000 miles of ocean surface in the Gulf of Mexico and offthe coast of Chile. The new data will improve understandingof the basic physical processes at work and how theyrelate to feedbacks between atmospheric ozone and climatechange. The team is also developing a representation ofthose processes that can be incorporated into global climatemodels. This research is a collaboration between four institutesand supported by the U.S. National ScienceFoundation.DISCOVERY OF ANCIENT HUMANREMAINS SPARKS PARTNERSHIP,DOCUMENTARY. James Dixon helpeddiscover 10,300-year-old human remains insoutheast Alaska in 1996 that have providednew insights into the lives of ancient peopleand helped cement a partnership betweenlocal tribes and scientists. Dixon was a lead researcher whostudied the bones, the earliest human skeletal remains everfound in Alaska or Canada. In the project’s early days,Dixon recognized the significance of the cooperationbetween the Tlingit and Haida tribes, scientists, and governmentofficials. The successful partnership and the knowledgegained from the ancient bones and artifacts found inthe cave are explored in a new 30-minute documentarytitled “Kuwóot yas.éin—His Spirit Is Looking Out from theCave.” The documentary was released on video this summerby the Sealaska Heritage Institute in Juneau, Alaska, incollaboration with the Tongass National Forest, DenverMuseum of Nature and Science, and the National ParkService. It was funded in part by the National ScienceFoundation’s Office of Polar Programs.NO PERVASIVE HOLOCENE ICE-RAFTED DEBRIS (IRD) SIGNAL INTHE NORTHERN NORTHATLANTIC? John Andrews, AnneJennings, and colleagues have assembledmarine core records of ice-rafted debris(IRD) off north Iceland, East Greenland, andLabrador that are at odds with an earlier and oft-cited studyshowing a pervasive ~1.5 thousand year periodicity of IRDdelivery during the Holocene (last ~11,400 years). Andrewset al. used quantitative X-ray diffraction on the
