Kogia Records in Brazilian Equatorial and Southwestern Atlantic Oceans

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The pygmy (Kogia breviceps) and dwarf (Kogia sima) sperm whales are cryptic cetaceans characterized by inconspicuous surfacing behavior, small group sizes, and deep‐diving habits, making visual detection particularly challenging. Here, we present the first broad‐scale passive acoustic monitoring (PAM) assessment of Kogia spp.

The Development of SONAR as a Tool in Marine Biological Research in the Twentieth Century

open access: yesInternational Journal of Oceanography, Volume 2013, Issue 1, 2013., 2013
The development of acoustic methods for measuring depths and ranges in the ocean environment began in the second decade of the twentieth century. The two world wars and the “Cold War” produced three eras of rapid technological development in the field of acoustic oceanography. By the mid‐1920s, researchers had identified echoes from fish, Gadus morhua,

Optimization of passive acoustic bird surveys: a global assessment of BirdNET settings

open access: yesIbis, Volume 168, Issue 2, Page 785-798, April 2026.
BirdNET is a popular machine learning tool for automated recognition of bird sounds. However, evidence on how to optimize its settings for accurate bird monitoring remains limited. Here, we evaluate how BirdNET settings influence model performance in identifying bird vocalizations and characterizing bird communities, using 4224 1‐min recordings from 67
