Researchers at the Mubadala Arabian Center for Climate and Environmental Sciences (Mubadala ACCESS) at NYU Abu Dhabi have found that reef fish from the Arabian Gulf, the world’s hottest sea, exhibit a higher tolerance to temperature fluctuations compared to those from more thermally stable coral reefs. However, the Arabian Gulf hosts fewer fish species overall, indicating that only certain fishes can withstand rising global temperatures.

As climate change accelerates, finding effective solutions that deliver outsized impact becomes increasingly crucial. Now, new research from Chapman University shows that a tiny marine mollusk native to the U.S. West Coast may hold the key to more effective coastal restoration. 

Brendan Cottrell studies the application of remote sensing and drone technology in marine mammal conservation at the Applied Remote Sensing Laboratory at McGill University where he recently completed his MSc. After graduating with a BSc in applied physics from Simon Fraser University, Cottrell worked with the British Columbia Marine Mammal Response Network where he was involved in marine mammal rescue, necropsies, and research. His current research is examining the ability of drones and remote sensing techniques to characterize and catalogue the prevalence and severity of entanglement scarring on large whales such as humpbacks.

He is the first author of a new Frontiers in Marine Science article in which he and his co-authors investigated the practicality of using smartphones to create 3D scans of stranded marine life that can aid in postmortem examinations and help scientists and conservationists protect marine species.

The worldwide network of telecommunications cables lying on the bottom of the world's oceans offers unique potential for scientific use if the fibre-optic cables themselves are used as or equipped with sensors. Based on this, the GFZ Helmholtz Centre for Geosciences in Potsdam and the GEOMAR Helmholtz Centre for Ocean Research Kiel are now setting up the research infrastructure SAFAtor (SMART Cables And Fiber-optic Sensing Amphibious Demonstrator), that can be used to monitor the world's oceans. It will be included in the portfolio of the major Helmholtz infrastructures and funded by the Helmholtz Association with 30 million euros as a strategic development investment. Among other things, the plan is to equip initially one demonstrator cable with appropriate sensor technology before deploying it in the deep sea in order to obtain important real-time data on climate and geological hazards. So far, almost no data exists from the seafloor. SAFAtor aims to close this data gap in the oceans. GFZ scientist Prof. Dr Fabrice Cotton, head of GFZ Section “Seismic Hazard and Risk Dynamic” is the project lead (PI). Co-PIs are GFZ researchers Prof. Dr Charlotte Krawczyk, Director of GFZ-Department Geophysics, who will take over the lead after two and a half years as scheduled, and Prof. Dr Frederik Tilmann, Head of GFZ Section “Seismology”, as well as Prof. Laura Wallace, Head of GEOMAR Research Unit “Marine Geodynamics”. The SAFAtor project will run for five years and will start with a kick-off meeting at the GFZ on Potsdam's Telegrafenberg on 5-6 March 2025.

Ideal locations and scales for offshore wind installations depend on both physical conditions and social acceptability. Rudolph Santarromana and colleagues conducted a spatial multi-criteria analysis considering both techno-economics and a socio-environmental impacts, including a broad range of possible concerns, including visual, fishing, marine life, and vessel traffic impacts.

An exploratory expedition describes two deep-sea, low oxygen ecosystems in the Red Sea, including some surprising fish. 

Some of the world’s leading scientific infrastructures, institutions and experts relating to biodiversity information are uniting around a new 10-year roadmap to ‘liberate’ data presently trapped in research publications. The initiative aims to enable the creation of a ‘libroscope’ - a mechanism for unlocking and linking data from scientific literature to support understanding of biodiversity, as the microscope and telescope previously revolutionized science.

Researchers at the University of Gothenburg have discovered that what was previously thought to be a unique seaweed species of bladderwrack for the Baltic Sea is in fact a giant clone of common bladderwrack, perhaps the world's largest clone overall.  The discovery has implications for predicting the future of seaweed in a changing ocean.
