This deep-sea anglerfish is Chaunacops coloratus, related to one of the new species recently found in Chile on Schmidt Ocean Institute’s #SEPacificSeamounts expedition. In 2012 MBARI researchers were the first to publish observations of these rare fish in their natural, deep-sea habitat. In addition to documenting these fish walking on the seafloor and fishing with their built-in lures, the researchers discovered that the fish change color from blue to red as they get older.
C. coloratus was first described from a single specimen collected off the coast of Panama during an expedition in 1891. However, for over 100 years, marine researchers collected deep-sea fish using trawl nets and dredges, so this anglerfish was never seen alive. That changed in 2002, when researchers from MBARI, Moss Landing Marine Laboratories, and the Monterey Bay National Marine Sanctuary used the remotely operated vehicle (ROV) Tiburon to explore Davidson Seamount—an extinct volcano off the coast of Central California.
As a result of MBARI’s ROV observations, researchers also learned that C. coloratus can live as deep as 3,300 meters (11,000 feet) below the ocean’s surface. Given the great depths these fish inhabit, it is no surprise that they had never before been seen alive. It is a testament to the usefulness of ROVs, which have provided marine scientists with a new window into the deep sea. MBARI has pioneered the use of ROVs to study animals, discover new species, document previously unknown behaviors, and collect individuals in their native habitat.
A friend just notified me that it is the annual Day of the Seafarer so here's a free comic about crossing the Pacific on an oceanographic research vessel to celebrate! (This voyage was also the source of the most popular thing I've ever put on Tumblr.)

50-prozentige Chance, dass 2023 das wärmste Jahr seit Beginn der Aufzeichnungen wird: NOAA
Klimaexperten der US-Regierung haben am Montag darauf hingewiesen, dass es eine Wahrscheinlichkeit von fast 50 Prozent gibt, dass 2023 das wärmste Jahr aller Zeiten wird. Sie warnen zudem davor, dass es im nächsten Jahr noch heißer werden könnte. Sarah Kapnick, Chefwissenschaftlerin der National Oceanic and Atmospheric Administration (NOAA), erklärte, dass 2023 bisher das drittwärmste Jahr seit…
