Teledyne Marine supplied a wide array of sensors and technology to empower Nekton’s manned submersible, ROVs, and surface vessel to collect critical data pivotal to this  mission.Equipment supplied by Teledyne Marine included:• RESON SeaBat T50-P Extended Range multibeam echosounder

July: Earth's Hottest Month Ever Recorded

degrees F above the 20th-century average of 56.9 degrees, tying with 2017 as the second-hottest year to date on record.It was the hottest year to date for parts of North and South America, Asia, Australia, New Zealand,  the southern half of Africa, portions of the western Pacific Ocean, western Indian Ocean and the Atlantic Ocean.Also, according to NOAA:-- Record-low sea ice: Average Arctic sea ice set a record low for July, 19.8% below average – surpassing the previous historic low of July 2012.-- Average Antarctic sea-ice coverage was 4.3% below the 1981-2010 average, making it the smallest

. Nekton Foundation was set up to help change our knowledge and understanding of the world’s oceans and to speed up the protection and governance of this last great wilderness, the deep ocean. Their First Descent initiative involved a series of expeditions, using two manned submersibles, in the Indian Ocean to help explore and conserve one of our least protected spaces.A Saab Seaeye Sabertooth using BlueComm free space optical modem for wireless communications.Photo: SonardyneIn this mission, they set up a depressor (a cabled receiver from a surface vessel) with a BlueComm 200 UV on one submersible

, and the Keeling Islands, west of Indonesia. From 2003 through 2013, their known range expanded to a few more locations in the eastern Indo-Pacific region. After the release of Dr. Cerchio’s video, the number of documented sightings increased dramatically across the world including the western Indian Ocean, eastern Atlantic off of Africa, western south Atlantic, northwestern Pacific and Oceania. The only major tropical or warm temperate oceanic basins not reporting sightings have been the eastern and central Pacific.These unevenly colored whales have filtering baleen instead of teeth and come from

from an underwater submersible.Underwater technology company Sonardyne International said the international news agency Associated Press (AP) used its BlueComm wireless through-water optical modem technology to broadcast live from a two-person submersible operating in waters off the Seychelles, in the Indian Ocean. AP said that the broadcast via YouTube was “the first multi-camera live signal in full broadcast quality from manned submersibles using optical video transmission techniques, in which the pictures transmit through the waves using the electromagnetic spectrum.”The broadcast is part

, and heat content.The most famous example of this work might have been a Munk-led experiment to see whether acoustics could be used as a way to estimate ocean temperatures on a global scale and thus, the effects of global warming. In 1991, at a remote location near Heard Island in the southern Indian Ocean, Munk’s team transmitted low-frequency underwater acoustic signals. The location had been chosen because the sound waves could travel on direct paths to listening stations in both the Pacific and Atlantic oceans. The premise was validated as stations from Bermuda to New Zealand to the United
