16 ST | July 2018 F or more than 15 years, Jupiter Research Foundation (JRF), based in Los Altos, California, has immersed itself in science and technology research and develop- ment with the primary objective of learning and creat- ing something new. Over the years, JRF has broadcast live whale song to the world, analyzed electrical sig- nals from single-cell organisms, developed an auton- omous ocean-going amateur radio and microscope and co-invented a high-tech, ocean-going, unmanned surface vehicle, the Wave Glider (WG) that has revolu- tionized how researchers monitor the world's oceans. This invention led to the formation of Liquid Robotics, a Sunnyvale, California, business that was acquired by The Boeing Co. of Seattle, Washington, in 2016. JRF has recently embarked on its most ambitious project yet: the Humpback Pacific Survey (HUMP- ACS). This mission combines two of JRF's passions: humpback whales and radio technology. Background A humpback whale's migration of 6,000 mi. is one of the longest of any mammal. It is well known that North Pacific humpback whales migrate from their northern, summer feeding grounds to nearshore, win- ter breeding grounds in Mexico, Hawaii, Japan and the Philippines. Some studies suggest there may be hump- back whales congregating in deeper waters between these nearshore grounds; however, scientists have not documented this. These studies include a photo-iden- tification record of a humpback whale that traveled between Mexico and Hawaii in one winter season and the study called "Structures of Population, Levels of Abundance, and Status of Humpback Whales" on mi- gratory destinations. Moreover, there are anecdotes of humpback whales near atolls far to the south and west of Hawaii. Previous song studies show there is mixing of humpbacks throughout the north Pacific, but it is not known when or how this occurs. While in their breeding grounds, humpbacks sing a song.
