Ship waves induce methane ebullition in the littoral zone of a large lake

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Methane (CH4) ebullition is a major emission pathway in lakes. However, ebullition remains difficult to assess, and data from large lakes are scarce. This study investigates ebullition in the littoral zone of a large lake, demonstrating that ship waves, even after traveling long distances, regularly trigger gas bubble releases from the ...

A Detailed Characterization of the Whistle Repertoire of Fraser's Dolphins (Lagenodelphis hosei) From the Lesser Antilles

open access: yesMarine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Fraser's dolphin (Lagenodelphis hosei) remains poorly studied due to its elusive behavior, rarity, and preference for deep offshore habitats. While dolphins use frequency‐modulated whistles for communication, detailed acoustic descriptions exist for only a few species.

Ship's Motion and Eddy Correlation Measurements of Surface Fluxes on the Small Research Ship NIES'94 in Lake Kasumigaura, Japan

open access: yesWater Resources Research, Volume 61, Issue 12, December 2025.
Abstract Lake surface fluxes provide important information about the lake's thermal environment. To capture their spatial variations, a ship serves as an excellent platform for applying the eddy correlation (EC) method. Although ship‐based EC measurements have been conducted over the ocean, this has not been the case over lake surfaces.

Spatial heterogeneity of dissolved oxygen and sediment fluxes revealed by autonomous robotic lakewater profiling

open access: yesLimnology and Oceanography, Volume 70, Issue 10, Page 2829-2843, October 2025.
Abstract Inland waters are under extreme anthropogenic pressure, while their ecosystem services, including water supply, food production, biodiversity, flood protection, and recreation, hinge on their health and condition. Therefore, water quality monitoring gains attention, and more resources are invested to increase spatial and temporal survey ...
