Manganese nodules as breeding ground for deep-sea octopods

Manganese nodules on the seabed are an important breeding ground for deep-sea octopods in some regions of the Pacific Ocean. As reported by a German-American team of scientists in the journal Current Biology, the octopods deposit their eggs onto sponges that only grow locally on manganese nodules. The researchers observed the previously unknown octopod species during diving expeditions in the …

HURL completes banner year of dives on a tight budget

The deep sea is a dark, cold, remote place—yet many Earth processes, and likely the origin of life itself, occur uniquely there. Few have been able to study its wonders in person. The Hawaiʻi Undersea Research Laboratory(HURL) based at the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology (SOEST) maintains two of the last manned …

Scientists drill deep to gain insights into East African climate history

Researchers from all over the world gathered in November at a beautiful but unassuming volcanic lake in East Africa with the hope of uncovering its hidden record of the climate history so intimately involved in the development of our species. In collaboration with the International Continental Scientific Drilling Programme (ICDP), an international team of Earth scientists, including postdoctoral researcher Christian …

Explaining mysterious source of greenhouse gas methane in the ocean

For decades, marine chemists have faced an elusive paradox. The surface waters of the world’s oceans are supersaturated with the greenhouse gas methane, yet most species of microbes that can generate the gas can’t survive in oxygen-rich surface waters. So where exactly does all the methane come from? This longstanding riddle, known as the “marine methane paradox,” may have finally …

UH researchers link quality of coastal groundwater with reef degradation on Maui

Land-use practices on tropical oceanic islands can have large impacts on reef ecosystems, even in the absence of rivers and streams. Land-based pollutants, such as fertilizers and chemicals in wastewater, infiltrate into the groundwaters beneath land and eventually exit into nearshore ecosystems as submarine groundwater discharge (SGD)—seeping into the coastal zone beneath the ocean’s surface. In a study published recently …

New model reveals adaptations of world’s most abundant ocean microbe

Researchers from David Karl’s laboratory at the University of Hawaiʻi at Mānoa and from Professor Jens Nielsen’s laboratory at Chalmers University of Technology in Göteborg, Sweden, developed a computer model which takes into account hundreds of genes, chemical reactions and compounds required for the survival of Prochlorococcus, the most abundant photosynthetic microbe on the planet. They found that Prochlorococcus has made …

A new study concludes warm climate is more sensitive to changes in CO2

It is well-established in the scientific community that increases in atmospheric CO2 levels result in global warming, but the magnitude of the effect may vary depending on average global temperature. A new study, published this week in Science Advances and led by Tobias Friedrich from the International Pacific Research Center (IPRC) at the University of Hawaiʻi at Mānoa, concludes that warm climates are more sensitive to changes in CO2 levels than cold …
