In a research paper published online Saturday in the Journal of Geophysical Research Oceans, a publication of the American Geological Union (AGU), scientists reported the southern Baffin Bay off West Greenland has continued warming since wintertime ocean temperatures were last effectively measured there in the early 2000s.Temperatures in the study were collected by narwhals, medium-sized toothed Arctic whales, during NOAA-sponsored missions in 2006 and 2007.
