Structural Variation in Whistle Patterns of Two Coastal Dolphin Species Co‐Occurring in the Southern Israeli Mediterranean Sea

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Two coastal dolphin species, the common bottlenose dolphin (Tursiops truncatus—Tt) and the short‐beaked common dolphin (Delphinus delphis—Dd), co‐occur along the southern Israeli Mediterranean coast, where the critically endangered Dd population faces ecological pressures, potentially including competitive exclusion by that of the Tt ...

A Cooperative Transmission Protocol based on Synchronization-free for Underwater Acoustic Networks

open access: yes, 2017
Underwater acoustic sensor network uses sound waves to be transmitted, resulting in underwater network with high propagation delay characteristics. Therefore, this paper designed for underwater network environment routing protocols, thereby reducing the ...

Description, Detection, and Classification of Hawaiian Monk Seal Vocalizations Through Deep‐Learning Methods: Biological and Conservation Applications

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The Hawaiian monk seal is a phocid Carnivore endemic to the Hawaiian Archipelago. This species was thought to be silent under water until the recent discovery that mature males produce at least six distinct calls year round, typically in bouts of two or more, with sound production linked to reproductive status.

Open Ocean Biogeochemical Impacts of Extreme Terrestrial Precipitation

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Extreme events reshape ocean ecosystems with significant implications for nutrient and carbon cycling. Here, we demonstrate that flooding on land can be a significant driver of biogeochemical variability in the open ocean, even in relatively dry climates.

Intrinsically Stretchable Piezoelectric Nanocomposites for Artificial Ultrasonic Sensory Synapse

open access: yesAdvanced Materials, Volume 38, Issue 52, 16 September 2026.
Applying ultrasonic stimulations to a soft‐stretchable underwater piezoelectric sensor based on the soft‐stretchable nanocomposite from the thermal cross‐linking between the ─C─F group of P(VDF‐TrFE) and the ─NH2 group of (PEG‐diamine) with incorporating amine‐terminated BTO@APTES nanofillers on the soft PDMS substrates generated high piezoelectric ...

Chemically Programmable Underwater Sound‐Absorbing Metamaterial via MXene Self‐Assembly

open access: yesAdvanced Science, Volume 13, Issue 51, 14 September 2026.
MXene self‐assembly creates a chemically programmable underwater metamaterial with quasi‐periodic layers and a chemical‐physical multi‐level constraint system. A crosslinker as a ‘chemical scissor’ precisely edits microscopic interactions, exciting deep‐subwavelength strong local resonances that induce near‐zero/negative effective bulk modulus (Keff ...
