Habitat Suitability for a Unique, Fully Marine American Manatee (Trichechus manatus) Population Primarily Depends on Presence of Submarine Freshwater Springs

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The American manatee (Trichechus manatus) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater.

A fiber optic Bragg grating seismic sensor

SPIE Proceedings, 2007
Here we present a fiber optic seismic waves sensor based on in-fiber Bragg gratings. Fiber Bragg Grating sensors have been demonstrated to have very high sensitivity to dynamical strain in the sub-micro-strain range and very extended dynamical response from static to very high frequency. The seismic sensing system is based on the integration of three

Laser interferometry based seismic sensor

SPIE Proceedings, 2003
Laser interferometry is one of the most sensitive and versatile techniques for small relative displacements measurement. For these reasons it is used or it is being introduced in many different fields of research. One of its possible applications is seismic activity monitoring, obtained by fixing the mirrors of an interferometer to the ground. In order
