When it comes to what people think about sharks, ‘Jaws’ has a lot to answer for. So while older generations shudder at the sound of the infamous two-note tuba alternation, what do younger generations think of sharks?
A new, integrated system will enable ocean science, exploration, and restoration efforts from a wider range of vessels, paving the way for more successful and efficient operations
Researchers have discovered a new way to help liquid flow in only one direction, but without using the flaps that engines and our circulatory system rely upon to prevent fluid backup.
Coral reefs will continue to experience severe heat stress as rising temperatures cause the oceans to become unbearably hot – but a new study shows that altering their feeding habits could allow local populations to avoid total extinction.
Predatory snails drill holes in the shells of their prey. Using these boreholes, a research team led by palaeontologist Martin Zuschin from the University of Vienna was able to create a time series of predator-prey relationships in the northern Adriatic over the past millennia. This showed that human influences led to a collapse in predator-prey relationships from the 1950s onwards.
New ocean projects across Gulf of Mexico states are getting under way this month thanks to federal funding support through the Inflation Reduction Act, which is supporting the equitable service delivery and modernization of the U.S. Integrated Ocean Observing System (IOOS) Regional Associations, including the Gulf of Mexico Coastal Ocean Observing System (GCOOS).
Using blushing coral star and genomic DNA analyses, researchers have uncovered vital links between coral populations at varying depths. They identified four distinct genetic lineages, finding strong connectivity between shallow and mesophotic populations. Importantly, mesophotic reefs emerged as crucial reproductive sources, particularly in the Lower and Upper Keys. Corals from these deeper zones hold significant potential to replenish and restore the declining shallow reefs in the Florida Keys National Marine Sanctuary.
Scientists have discovered the cuisine preferences of two resident killer whale populations: the Alaska residents and the endangered southern residents. The two populations show broad preference for salmon, particularly Chinook, chum and coho. But they differ in when they switch to hunting and eating different salmon species, as well as the other fish species they pursue to supplement their diets.
Researchers used dual-nozzle 3D printing technology to construct plant-based yellow croaker tissue analogs by soy protein isolate–xanthan gum-starch complex (as simulated muscle ink) and nanostarch-carrageenan emulsion gel (as simulated fat ink). Successfully, indicators of testing demonstrated that 3D-printed plant-based yellow croaker flesh with a composite structure had a good simulation quality.
New study challenges previous assertions of Gulf Stream slowdown
Florida State University researchers at the Coastal and Marine Laboratory and the School of Communication are working to educate the public and help clean up Wakulla Springs, thanks to funding from the Florida Legislature.
Van Gogh’s brushstrokes in “The Starry Night” create an illusion of sky movement so convincing it led researchers to wonder how closely it aligns with the physics of real skies. Marine sciences and fluid dynamics specialists analyzed the painting to uncover what they call the hidden turbulence in the artwork.
A research team has developed an innovative and sustainable method to extract collagen from sardine bones using water extracts from banana peels, a common agricultural waste in Malaysia.
A series of seemingly small processes helps carry carbon dioxide from the ocean’s surface to the deep sea, where it can be stored away for decades.
Increased capabilities in the human-occupied submersible Alvin open a window on a rarely seen behavior
Scientists report that underwater noise pollution — from both large and small vessels — forces northern and southern resident orcas to expend more time and energy hunting for fish. The din also lowers the overall success of their hunting efforts. Noise from ships likely has an outsized impact on southern resident orca pods, which spend more time in areas with high ship traffic.
The Paul G. Allen Frontiers Group has selected UC San Diego’s Scripps Institution of Oceanography to receive a four-year, $10 million grant funded by the Paul G. Allen Family Foundation to establish the Allen Discovery Center for Neurobiology in Changing Environments. The center will take a multidisciplinary approach to investigating how climate change may impact the nervous systems and behavior of marine animals.
New research led by FAMU-FSU College of Engineering Assistant Professor Ebrahim Ahmadisharaf examined how drought and water volume in the Lower Apalachicola River watershed affect nitrogen and phosphorous, crucial nutrients for a healthy aquatic ecosystem.
SEQUIM, Wash.—Officials gathered at the Sequim campus of the Department of Energy’s Pacific Northwest National Laboratory today to dedicate DOE’s first hybrid-electric research vessel, RV Resilience.The event marks the start of a new era of marine energy research at PNNL-Sequim, part of DOE’s Office of Science national laboratory system and Resilience’s new home port.
A report on more than 40 years of research on Wisconsin lakes is highlighting some of the lessons scientists have learned about aquatic invasive species, including that far more ecosystems are playing host to non-native species than previously thought. However, the researchers note, those species aren’t necessarily detrimental to their new habitat and, in some cases, the negative “impacts of invasive species control may be greater than the impacts of the invasive species” themselves.
