Petty Officer 1st Class Michael Nicholas, a Navy diver with Mobile Diving and Salvage Unit 1 and volunteer for the Sanctuary Ocean Count project, measures the approximate size of a whale with a ruler while observing it in Kaneohe Bay at Pyramid Rock Beach, Feb. 22, 2014. The annual Sanctuary Ocean Count project, coordinated through the National Oceanic and Atmospheric Administration's Hawaiian Islands Humpback Whale National Marine Sanctuary, monitors the endangered humpback whale, which migrates to Hawaii between November and April. The counts occur during the last Saturday in January, February and March, which NOAA considers the season’s peak. On Oahu, there are more than 20 different sites designated for whale counting. Two sites are aboard MCB Hawaii: Atop the Coast Guard-owned tower at Pyramid Rock Beach and at Mokapu Point near Kaneohe Bay Range Training Facility, both restricted areas.
