| Humpback whale distribution. The blue dots show where humpback whales were sighted near Kauai, Hawaii during January - April 2001. The inner and outer lines around Kauai show where the water is 100 fathoms (600 feet or 183 meters) and 1000 fathoms (6000 feet or 1830 meters) deep, respectively. The humpback whales were often sighted in nearshore water, less than 100 fathoms deep. The red dot north of Kauai shows where the ATOC/NPAL source is located.
