Underwater acoustic slant range measurements related to weather and sea state [PDF]

, 2018
Underwater range measurements are key factor in underwater acoustic positioning, used in Long Base-Line (LBL) or Ultra Short Base-Line (USBL) computing techniques. These measurements are commonly carried out through acoustic communications between modems

Hearing in the Juvenile Green Sea Turtle (Chelonia mydas): A Comparison of Underwater and Aerial Hearing Using Auditory Evoked Potentials

, 2016
Sea turtles spend much of their life in aquatic environments, but critical portions of their life cycle, such as nesting and hatching, occur in terrestrial environments, suggesting that it may be important for them to detect sounds in both air and water.

Identification of Risks in the Course of Managing the Deep Sea Archeological Projects Using Marine Robotics [PDF]

, 2016
An analysis is conducted of the basic risks that occur when managing the projects of deep-sea archeological research. It is proposed to consider possible risks of such projects in the form of a general set of risks that contains subsets of the identified

Review of Underwater

Open Rivers Rethinking Water Place & Community, 2022
Underwater is surprising. Lois Hendrickson and Emily Beck, the exhibit’s curators, planned the exhibit after a visitor asked if the Wangensteen Historical Library of Biology and Medicine’s expansive collection included any materials related to algae.

Soft-Switching Proximate Time Optimal Heading Control for Underactuated Autonomous Underwater Vehicle

IEEE Access, 2019
In this paper, a soft-switching proximate time-optimal control (PTOC) is proposed based on the model-compensation extended state observer (ESO) and Takagi-Sugeno fuzzy switching, for the fast set-heading tracking of underactuated autonomous underwater ...

Underwater Acoustic Micromodem for Underwater Internet of Things

Wireless Communications and Mobile Computing, 2022
Underwater acoustic communication (UAC) networks are becoming a hot spot for research due to the growing demand for ocean development. Previous acoustic modems were mainly designed for the field of ocean engineering construction and scientific investigation, and consequently, with the characteristics of large size and high-power consumption, a low-cost,

Time Reversal Acoustic Communication Using Filtered Multitone Modulation

Sensors, 2015
The multipath spread in underwater acoustic channels is severe and, therefore, when the symbol rate of the time reversal (TR) acoustic communication using single-carrier (SC) modulation is high, the large intersymbol interference (ISI) span caused by ...
