Dive into ocean exploration by exploring materials such as stories, ocean facts, and images and videos, organized by topic for learners of all ages and levels.

In the Field: 2026

NOAA Ocean Exploration works with partners to explore previously unknown areas of our ocean, making discoveries of scientific, economic, and cultural value and supporting innovations in exploration tools and capabilities. In 2026, we will lead and support expeditions and fieldwork in the Pacific Ocean, Caribbean Sea, and Lake Michigan.

Status: NOAA Ship Okeanos Explorer — In Port

NOAA Ship Okeanos Explorer arrived in Suva, Fiji, on September 17, marking the end of the 2026 American Samoa ROV + Mapping Exploration expedition. Our next expedition, 2026 American Samoa Mapping, begins on September 24. It will include mapping operations, focusing on waters around American Samoa before transiting to Hawai‘i, filling critical gaps in seafloor mapping data along the way.

Hoplostethus crassispinus – in the same genus as, and related to the orange roughy. Unlike the orange roughy which lives in schools, this fish lives a somewhat solitary existence. There is a general sense that these fish have a level of curiosity because they often retreat into holes when imaged, but then turn around to investigate the investigator. This one was spotted checking out remotely operated vehicle Deep Discoverer during the 2015 Hohonu Moana: Exploring Deep Waters off Hawaiʻi expedition.
