The NOAA Ship Okeanos Explorer has kicked off its 2017 field season so far with amazing dives in the waters off American Samoa, a US territory in the southern Pacific Ocean. In February 2017, the expedition team explored the Vailulu’u Seamount, an underwater volcano located east of the Samoan Island of Ta’u. This offered scientists a rare and exciting opportunity to observe the geological and ecological characteristics of an active underwater volcano.

Completed on July 10th, leg three of the NOAA Ship Okeanos Explorer‘s EX1605 expedition was chock-full of discoveries. The Okeanos‘s remotely operated vehicles (ROVs) conducted 22 dives, exploring many recently-mapped sites in the Mariana Trench Marine National Monument (MTMNM). They ventured where no ROVs have dove before.
Ship-based sonar mapping, along with ROV imaging and rock sampling, revealed new hydrothermal vent sites, deep-water coral reefs, the first petit-spot volcano found in US waters, and a new mud volcano in the MTMNM.
Amid the geological findings, biologists cataloged many new species. The pictures and videos below highlight some of the newly-discovered inner-space aliens (strange alien-looking creatures) from leg three of the Okeanos Explorer‘s EX1605 expedition.
This cusk eel, found at Unnamed Forearc on June 28th, 2016, was among the first new species discovered during this leg of the expedition.
This ghost-like fish, dubbed “Casper” by land-based scientists, is a species in the fish family Aphonoidae. Until June 30th, 2016, when the ROVs came across Casper, no fish in this family have ever been seen alive.
After a long geology-based dive, the ROVs came upon this undescribed species of Pachycara, commonly called eelpout.
The scientists wished they had enough time to collect this new species of hard sponge that they discovered on July 6, 2016.
But, they were able to collect this new species of stalked glass sponge!
For more ocean exploration and discoveries be sure to check out the Nautilus Live website for updates from the E/V Nautilus! Situated of the California coast, the Nautilus is currently (pun intended) mapping and conducting dives off the Channel Islands.
The Okeanos won’t be diving again until June 27th, 2016. Until then, check out dive highlights on our YouTube channel, and the NOAA Ocean Explorer YouTube channel! For more details about individual dives from the NOAA Ship Okeanos Explorer visit the NOAA Okeanos Explorer website.

In the Marianas, the west-moving Pacific plate is forced beneath the Philippine plate as they collide, a process known as subduction. As a result, the region is characterized by many geological features including fault lines, earthquakes, volcanoes, cold seeps, hydrothermal vents, and mud volcanoes.

About 12.5 miles off the coast of Farallon de Pajaros, within the Mariana Trench Marine National Monument, lies the Ahyi Seamount, an active underwater volcano. This site remained unexplored until June 22nd, 2016, when the NOAA Ship Okeanos Explorer launched its remotely operated vehicles (ROVs) to investigate the volcano. Continue reading To Boldly Go… Ahyi Seamount
If you’ve worked at the Inner Space Center for as long as Alex and I have, it’s rare to see something you’ve never seen before during a live dive. The E/V Nautilus is currently studying volcanic activity in the area surrounding the Galapagos Islands, but they stumbled upon a field of what they believe to be shark eggs. As soon as they appeared onscreen, I called the ISC Video Crew into Mission Control to take a look. Continue reading This is what a shark egg looks like?
Recently, I joined up with local up-and-coming researcher, Brennan Phillips, on an expedition to the remote waters of the Solomon Islands. At the bottom of this post, you’ll find great article on the work. A huge thank you goes to local legend Todd McLeish for writing the piece.

It’s been a little over a week since the Nautilus has been searching the depths for the next big discovery. Not to downplay anything here – I mean, they have been at sea since early June you know. So far this summer they have been exploring the “Unknown America.” Continue reading E/V Nautilus, Back in the Game
