#SampleSpotlight! Pictured is a fragmented lava suspended in lithified sediment. When exposed to UV light, the sediment phosphoresces, glowing green for several seconds. This brief "glow in the dark" effect tells us that the sediment is made out of calcite and/or a phosphate mineral.

The #RepublicoftheMarshallIslands is an island nation in the Central Pacific region of #Micronesia consisting of 29 low-lying atolls and five main islands surrounded by 2.13 million km2 of mostly unexplored seafloor. Stay tuned as we explore the #deepsea of this special place.

Another #IronBottomSound #shipwreck we explored during the NA173 expedition, originally discovered by Dr. Robert Ballard in 1992, was the #USSPreston. The 104-meter Mahan-class destroyer was lost in the Third Battle of #SavoIsland on November 14, 1942.

As we explore #IronBottomSound, we're using @unhresearch.bsky.social's #USVDriX to create a high-resolution map of the entire basin and identify potential exploration sites. #DriX has an EM712 #multibeamsonar and topside sensors to support piloting from both shoreside and onboard #EVNautilus.
