Exploring and understanding the ocean is an important field of scientific study. Acquiring
accurate and high-resolution temperature and depth profiles of the oceans over relatively short
periods of time is an important basis for understanding ocean currents and other associated physical
parameters. Traditional measuring instruments based on piezoelectric ceramics have a low spatial
resolution and are not inherently waterproof. Meanwhile, sensing systems based on fiber Bragg
grating (FBG) have the advantage of facilitating continuous measurements and allow multi-sensor
distributed measurements. Therefore, in this paper, an all-fiber seawater temperature and
depth-sensing array is used to obtain seawater temperature and depth profiles. In addition, by
studying the encapsulation structure of the FBG sensors, this paper also solves the problem of the
measurement error present in traditional FBG sensors when measuring seawater temperature.
