Scientists chart seafloor of one of the largest marine protected areas on Earth

Falkor mapping control room

On April 11, scientists returned from a 36-day mapping expedition to Papahānaumokuākea Marine National Monument (PMNM) in the remote Northwestern Hawaiian Islands. The Monument is the largest protected area in the United States, encompassing an area greater than all its national parks combined, yet over half its seafloor has never been mapped in detail due to the limited availability of the advanced sonar systems required. ...

HURL enables discovery of dramatic long-term shift in Pacific Ocean ecosystem

Hawaiian gold coral

The Hawaii Undersea Research Laboratory (HURL) at the University of Hawai’i at Mānoa School of Ocean and Earth Science and Technology (SOEST) has enabled scientists to determine that a long-term shift in nitrogen content in the Pacific Ocean has occurred as a result of climate change.   Researchers from the Lawrence Livermore National Laboratory (LLNL) and the University of California – Santa Cruz analyzed ...

[VIDEO] Giant World War II aircraft-carrying submarine discovered off Oahu coast

Pisces V submarine at I-400 Gun Deck

A World War II-era Imperial Japanese Navy mega-submarine, the I-400, lost since 1946 when it was intentionally scuttled by U.S. forces after its capture, has been discovered in more than 2,300 feet of water off the southwest coast of O‘ahu.  The discovery resolves a decades-old Cold War mystery of just where the lost submarine lay, and recalls a different era ...

Submarine canyons a source of marine invertebrate diversity, abundance

submarine canyons

Submarine canyons play an important role in maintaining high levels of biodiversity of small invertebrates in the seafloor sediments of the main and northwestern Hawaiian Islands, according to research from the University of Hawai‘i at Mānoa. What’s more, scientists have used this data to draw new connections between the levels of faunal diversity and the heterogeneity of submarine canyon landscapes ... Read More »
