The image features a collection of deep-sea creatures arranged against a black background. The arrangement includes various species of fish and small marine animals, each with distinctive features. In the upper left corner, there's a large fish with a round body and dark eyes, accompanied by a bright orange-red shrimp. To its right, another shrimp displays long, luminous blue appendages. Below, a slender, elongated fish with a slightly shiny body is positioned horizontally. The center of the image showcases a large shark-like creature with a streamlined body and prominent fins. On the right, a thin, vibrant blue fish extends vertically with noticeable fins. At the bottom left, a bulbous-headed fish is oriented towards the viewer, flanked by smaller shrimp, while a fish with a long, pointed snout swims nearby. On the bottom right is an elongated fish with reflective scales.

Accelerating Ocean Exploration Through Cloud-Native Processing of Active Ocean Sonar Data

A team of scientists has developed and added two new tools to their open-source data-processing package Echopype to make ocean sonar data easier to process and analyze using cloud computing.

Status: NOAA Ship Okeanos Explorer

In October, NOAA Ocean Exploration wrapped up operations on NOAA Ship Okeanos Explorer for the 2025 calendar year. We expect to resume operations in the Pacific in April 2026. Keep an eye out for more information!

Predation events always generate a lot of excitement among our scientists. This one observed during Dive 09 of the 2019 Southeastern U.S. Deep-sea Exploration was particularly interesting because it featured an unidentified Henricia sea star feeding on a Chondrocladia carnivorous sponge.

Predation events always generate a lot of excitement. This one observed during the 2019 Southeastern U.S. Deep-sea Exploration was particularly interesting because it featured an unidentified Henricia sea star feeding on a Chondrocladia carnivorous sponge. We had several interesting sponge sightings during this expedition, as described in this feature, “Not Your Average Sponges.”
