We just finished sampling along the “DBO line”. This is a line of stations located in the Chukchi Sea just to the south of Barrow, AK. An international group of scientists has been sampling across this line of stations when in the region with an oceanographic ship. The Healy has already sampled across the DBO line twice this year. Other ships and projects, including some of my work near Barrow, also have sampled the line. Together, by sharing the data, the scientific community gets an understanding of temporal changes in this sea through the summer and fall seasons. The November 22-23 sampling of the DBO line is the latest such sampling in any year and the only sampling to occur during early winter. We are eager to compare what we found with the data from the earlier sampling.

|Yesterday we had a “visit” from land, a helicopter from the North Slope Borough Search and Rescue in Barrow came to pick up a crewmember who needed to get off of the ship.|
