Elkhorn coral (Acropora palmata) in Tres Palmas Marine Reserve, Rincón, Puerto Rico. This coral can form reef crests and cause waves to break, providing significant protection to the coast.

A novel stereo CoastCam will be installed on at dune at Pea Island for the duration of the experiment.

The R/V Sallenger tows the SQUID-5 over Looe Key reef with a NOAA Sanctuary boat in the background patrolling the Looe Key area to warn recreational vessels of the ongoing research activity.

This beautiful red jellyfish in the genus Poralia may be an undescribed species. It was seen during the third transect of Dive 20 of the 2021 North Atlantic Stepping Stones expedition, at a depth of 700 meters (2,297 feet).

This large bubblegum coral (Paragorgia arborea) was observed during Dive 19 of the 2021 North Atlantic Stepping Stones expedition. Based on published radial growth rates for this species, this colony is approximately 100 years old!

Towards the end of Dive 19 of the 2021 North Atlantic Stepping Stones expedition, we continued to observe the scattered rock debris sitting on the lobate and pillow lava outcrops that we’d seen earlier, suggesting that the pinnacle of Retriever Seamount was perhaps a late-stage eruption site and that it remains largely susceptible to continued erosional modification

Remotely operated vehicle Deep Discoverer surveys a large boulder covered in bamboo corals during the 2021 North Atlantic Stepping Stones expedition. Bamboo corals were locally abundant on these large boulders and more spread out throughout different hard-bottom habitats.

During Dive 11 of the 2021 North Atlantic Stepping Stones expedition, we discovered what is defined by the Oslo/Paris Convention (OSPAR) as a multispecies coral garden (100 - 700 coral colonies per every 100 square meter).
