This weekend the NOAA Ship Okeanos Explorer visited Shostakovich Seamount, and began its “Water Column Wonderland” week. Check out some of the unique creatures that live beneath the sea with imagery captured by remotely operated vehicle (ROV) Deep Discoverer! Continue reading Weekend Discoveries
The NOAA Ship Okeanos Explorer had an amazing dive March 9, 2017 on Pao Pao Seamount, an underwater mountain in the Tokelau Seamount Chain in the South Pacific. Continue reading The Scintillating Sea Life of Pao Pao Seamount
The NOAA Ship Okeanos Explorer has been having an amazing cruise leg with lots of new discoveries. Last night the scientists made another amazing discovery. The scientists observed an aphyonid fish, roughly 10 cm long. This is the first time that this creature has ever been seen alive!
Scientists were thrilled to see such an amazing fish! This eel-like fish has been found around 2,000-6,000 meters. The aphynoid fish had transparent skin and reduced eyes. They are known for their unusual reproductive habits.
Be sure to follow the NOAA Ship Okeanos Explorer for more amazing discoveries!
The EX1605L1 leg of NOAA Ship Okeanos Explorer‘s trip to the Marianas was captivating, to say the least! From new species of jellyfish, to hydrothermal vent chimneys, this exploration leg was jam-packed with discoveries.
Okeanos started this cruise leg near Guam, then moved towards the Marianas Trench Marine National Monument (MTMNM) and the Commonwealth of the Northern Mariana Islands (CNMI). The Marianas Trench is known as the deepest part of the ocean, at almost 11,000 meters deep! The intention behind this cruise leg was to gather baseline knowledge of the biodiversity and geology of the area. The NOAA team onboard used their remotely operated vehicle (ROV) Deep Discoverer, “D2” to explore the area.
As always, the Inner Space Center at URI published those streams in real-time to YouTube and scientists worldwide. Some dives attracted as many as 2,500 simultaneous viewers.
The biology encountered in the Marianas was phenomenal! The cruise leg started off with a six-gill shark sighting at Santa Rosa Reef.
We discovered a wide variety of creatures inhabiting the area:
One of the most enthralling discoveries was a new species of jellyfish! This hydromedusa was found at Enigma Seamount at roughly 3,700 meters:
The Okeanos Explorer also made some great geological discoveries. They explored a newly-discovered hydrothermal vent site boasting one of the highest temperatures recorded in the Marianas region: 339 degrees Celsius. (Most of the deep sea is a chilly 2 degrees Celsius.) The 30-meter chimney base was releasing black “smoke” made up of iron and anhydrite precipitate.
There were also young lava flows that had created glassy pillow mounds. The area was so new that no animals had yet colonized the area.
That’s a wrap for Leg 1! Come back for more deepwater exploration on June 17th!
