This study introduces an amphibious unmanned aerial vehicle (AUAV) with deep learning for efficient marine monitoring. The AUAV system achieves high accuracy in detecting underwater litter and segmenting sea cucumbers, offering a practical alternative for shallow-water ecological surveys.

Area Of Science

  • Marine Biology
  • Robotics
  • Artificial Intelligence

Background

  • Traditional marine monitoring methods are inefficient and costly.
  • Modern techniques like AUVs and P-SSS have limitations in cost, labor, and data quality.

Purpose Of The Study

  • To develop an efficient and practical shallow-water ecological monitoring system.
  • To integrate deep learning with an amphibious unmanned aerial vehicle (AUAV) for marine surveys.

Main Methods

  • An amphibious unmanned aerial vehicle (AUAV) equipped for aerial and underwater imaging with real-time GNSS.
  • Integration of YOLOv8 deep learning model for underwater litter detection and sea cucumber instance segmentation.
  • Quantitative analysis of sea cucumber size using instance segmentation results.

Main Results

  • YOLOv8 achieved a mean average precision (mAP) of 0.764 for underwater litter detection, a significant improvement over previous benchmarks.
  • YOLOv8 demonstrated high performance in sea cucumber object detection (mAP 0.792) and instance segmentation (mAP 0.798).
  • The framework enabled accurate pixel-level size estimation of sea cucumbers.

Conclusions

  • The AUAV-YOLOv8 framework provides a highly efficient and quantitative solution for shallow-water ecological monitoring.

Ecological Disturbance 02:26

21.1K

An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

Ecological disturbances can be caused by an event as small as the trampling of underbrush to an incident as wide-ranging as a...

Ecological Succession 02:17

21.6K

Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...

Ecological Niches 02:02

26.8K

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

Multiple species cannot occupy the exact same niche within their habitat. If the niches of two or more species overlap to a large extent, the competitive exclusion principle dictates that one species will outcompete the...

Vision 01:24

60.3K

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Light is absorbed by the rod and cone...

Water: A Bronsted-Lowry Acid and Base 02:30

The reaction between a Brønsted-Lowry acid and water is called acid ionization. For example, when hydrogen fluoride dissolves in water and ionizes, protons are transferred from hydrogen fluoride molecules to water molecules, yielding hydronium ions and fluoride ions:
 
Base ionization of a species occurs when it accepts protons from water molecules. In the example below, pyridine molecules, C5NH5, undergo base ionization when dissolved in water, yielding hydroxide and pyridinium ions:

Color Vision 01:24

1.5K

Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
