Noise levels and sources in the Stellwagen Bank National Marine Sanctuary and the St. Lawrence River Estuary [PDF]

, 2005
Although ambient (background) noise in the ocean is a topic that has been widely studied since pre-World War II, the effects of noise on marine organisms has only been a focus of concern for the last 25 years.

A Sandwich Coating Containing Micro-perforated Panel for Underwater Sound Absorption

IOP Conference Series: Materials Science and Engineering, 2019
Abstract This paper focuses on the underwater application of Micro-perforated panel (MPP) for broadband sound absorption. In this paper, MPP-rubber coating (MPPRC), a novel sandwich anechoic coating embedded with MPP in high-viscosity condition, is proposed.

Volume scattering function measured in the oceans and lakes (2009–2024)

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Volume scattering function (VSF) is a fundamental inherent optical property but has been scarcely measured in natural environments. To address this observational gap, we compiled a dataset of non‐water, particle VSFs (βp) measured in a variety of waters, covering inland, coastal, and open oceans. A total of 1013 βp with an overall ≤ 1° angular

Laboratory Characterization of Cryogenic Frost‐Point Hygrometers Using an Upper Air Simulator

Meteorological Applications, Volume 33, Issue 3, May/June 2026.
Cryogenic frost‐point hygrometers (CFHs) are widely used to accurately measure water vapor pressure in the upper atmosphere. The performance of CFHs has been thoroughly evaluated using an Upper Air Simulator (UAS), a controlled laboratory system designed to generate and regulate frost‐point levels across a range of temperatures.

Effect of Insect Damage on Seed Germination of Black Locust (Robinia pseudoacacia)

Plant Species Biology, Volume 41, Issue 3, May 2026.
As shown in the figure, the white‐circled black locust seeds absorbed water and swelled, whereas the red‐circled seeds remained unswollen. This observed cryptic seed heteromorphism in germination is likely attributable not only to the development of an impermeable seed coat during maturation but also to physical damage caused by insects. ABSTRACT Black

Mechanisms and design of composite sandwich structures for underwater sound absorption

Journal of Physics: Conference Series
Abstract This research focuses on enhancing the acoustic properties of underwater composite sandwich structures. Initially, a comparison is made between the acoustic performance of composite sandwich structures with traditional symmetric and asymmetric face sheets.

Heuristic algorithm-enhanced inverse design of deep-subwavelength hybrid metamaterials for ultra-broadband underwater sound absorption

Materials & Design
This study proposes a hybrid acoustic metamaterial (HAM) composed of four quasi-Helmholtz resonators (QHRs, with rubber liners and embedded necks) and one boundary-constrained viscoelastic material (BVM) arranged in parallel.
