Even in calm weather, AUV teams are concerned about other users in the area. In this photo, taken on Wednesday, a Navy boat approaches a sailboat to inform it that it is in Navy-controlled area and must leave the area. In most places, AUV teams have to politely request that the boat leave the area, or wait for it to move on. Image courtesy of AUVfest 2008: Partnership Runs Deep, Navy/NOAA, OceanExplorer.noaa.gov.
