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.

Hydraulic Abrasion-Resistant Elastic Epoxy Resin Materials

Advances in Materials Science and Engineering, 2019
The abrasion of hydraulic concrete structures caused by the washing action of flowing water is a common problem and cannot be solved by simply increasing the strength of the concrete.

Sensitivity of the mussel Mytilus edulis to substrate‑borne vibration in relation to anthropogenically generated noise [PDF]

, 2015
© 2015 Inter-Research. Many anthropogenic activities in the oceans involve direct contact with the seabed (for example pile driving), creating radiating particle motion waves.

Study of Corellation between Coral Reef Cover and Abundance of Reef Fish in Poncan Gadang Island Sibolga City

Journal of Physics: Conference Series, 2020
Poncan Gadang Island used by people for marine tourism, underwater and fisheries activities. These activities make the island’s area as a ship transportation route and feared the condition of the coral reef ecosystem will be damaged.

Underwater Fish Detection with Weak Multi-Domain Supervision

, 2019
Given a sufficiently large training dataset, it is relatively easy to train a modern convolution neural network (CNN) as a required image classifier. However, for the task of fish classification and/or fish detection, if a CNN was trained to detect or ...

Real-time Model-based Image Color Correction for Underwater Robots

, 2020
Recently, a new underwater imaging formation model presented that the coefficients related to the direct and backscatter transmission signals are dependent on the type of water, camera specifications, water depth, and imaging range.
