PML Study Explores Marine Protection Opportunities Amidst Deep Sea Mining

Protected areas have been set up to shield deep-sea life from the impacts of seabed mining in the Pacific Ocean. However, new research led by scientists at Plymouth Marine Laboratory (PML) and published in Nature Ecology & Evolution, highlights an opportunity to make these protections even more effective. The study suggests that adding a small number of strategically located protected areas could help transform existing reserves into a more connected network, enabling tiny drifting larvae that have been cast adrift after disturbance to recolonize more successfully.The research team focused on the

Marine Mammal Classifier App Wins Canadian Edition of Ocean Hackathon 10

of the South Island Prosperity Partnership (SIPP), Greater Victoria's economic development alliance. Regional editions were simultaneously convened in twelve cities and nine countries around the world. Produced by Campus Mondial de la Mer, the international competition brings together marine science and digital innovation in a format designed to inspire and engage emerging ocean entrepreneurs. Participants gain access to vast marine databases and receive guidance from experienced mentors and industry professionals while developing their projects. They then pitch their prototypes to a panel

During the expedition, two gliders provided continuous physical and biological data, including temperature, currents, dissolved oxygen, microstructure turbulence, and zooplankton presence. This process helped scientists select data-collection stations in near-real time. © Alex Ingle / Schmidt Ocean Institute

Comprehensive Study Measures How Salt Finger Mixing Feeds Marine Life

; said Selden, an assistant professor at Rutgers University. “We will assess plankton growth, diversity, and grazing rates against physical measurements of salt finger mixing to determine how the process feeds surface ecosystems. These findings will clarify how fine-scale ocean mixing drives both marine food webs and potential carbon export to the deep sea.” The ocean absorbs approximately 30% of all human-created carbon emissions. Much of the absorbed carbon dioxide is captured by phytoplankton during photosynthesis and converted into organic carbon. When these phytoplankton are consumed

ASL Acoustic Profiler Reveals Vertical Migration of Midge Larvae in Lake Malawi

ASL has highlighted their involvement in a field and laboratory study that recently appeared in the July 23, 2026 edition of the journal Science. This study, led by Dr. Philip Matthews of the University of British Columbia in collaboration with researchers from the Department of Fisheries in Malawi, the Scottish Oceans Institute, the University of St Andrews UK and Cupar Analytics UK, revealed how the aquatic larvae of the midge fly Chaoborus edulis have exhibited remarkable crush-resistant air sacs that allow them to undertake daily vertical migrations to extraordinary depths in Lake Malawi, East

A Graneledone octopus, a suspected new species, moves across the seafloor during a deep-sea ocean expedition off the coast of Trinidad and Tobago. This species was first observed during an expedition Dr. Diva Amon (SpeSeas) participated in 2014, but was not confirmed or collected until this mission. Researchers made dozens of other discoveries on the trip, including at least 20 suspected new species, three of which may be new genera. © ROV SuBastian / Schmidt Ocean Institute

Caribbean-Led Expedition Explores Deep Sea Offshore Trinidad and Tobago

Marine scientists from Trinidad and Tobago recently conducted the first locally led and most comprehensive deep-sea survey of the islands’ surrounding ocean during an expedition aboard Schmidt Ocean Institute’s R/V Falkor (too). During the month-long expedition in July, the team located over 25 active cold seeps, discovered 20 suspected new species, and mapped approximately 13% of the country’s marine territory.The potential new species include an octopus first discovered during a 2014 expedition, in which the expedition’s Chief Scientist, Dr. Diva Amon, participated.

Gulf Hypoxic Zone Found to Be Smaller Than Expected

,” are areas with little to no oxygen in the water, which can negatively impact fish, shellfish, corals and aquatic plants by making critical habitat unavailable to bottom species. The annual hypoxic zone survey was led by scientists at Louisiana State University and the Louisiana Universities Marine Consortium (LUMCON). The survey cruise was conducted aboard the LUMCON research vessel Pelican from July 24-30. Data from the survey is available online for the public. The measured hypoxic zone is smaller than anticipated this year due to Tropical Storm Bertha passing through the northern Gulf
