Bathymetry of the Coral Reefs of Weizhou Island Based on Multispectral Satellite Images

Remote Sensing, 2017
Shallow water depth measurements using multispectral images are crucial for marine surveying and mapping. At present, relevant studies either depend on the use of other auxiliary data (such as field water depths or water column data) or contain too many ...

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

Advanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Lunar and seasonal patterns of a longnose emperor spawning aggregation in Palau

Scientific Reports
Many species of reef fishes form spawning aggregations during predictable seasons and lunar phases, which are often targeted by fishers, leading to their depletion over time.

Variation in growth rates of branching corals along Australia’s Great Barrier Reef

Scientific Reports, 2017
Coral growth is an important component of reef health and resilience. However, few studies have investigated temporal and/or spatial variation in growth of branching corals, which are important contributors to the structure and function of reef habitats.

Using size-weight relationships to estimate biomass of heavily targeted aquarium corals by Australia’s coral harvest fisheries

Scientific Reports, 2023
Coral reefs are highly threatened environs subject to ongoing unprecedented degradation as a result of anthropogenic activities. Given the existential threat to coral reef ecosystems, extractive industries that make use of coral reef resources, are ...

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Ecology and Pathology of Novel Plaque-Like Growth Anomalies Affecting a Reef-Building Coral on the Great Barrier Reef

Frontiers in Marine Science, 2016
Here we identify ecological and structural characteristics of a novel plaque-like growth anomaly (GA) at outbreak levels in a population of the staghorn coral, Acropora muricata, on the Great Barrier Reef.

Private Capital to Improve Nature-Based Solutions for Coastal Protection: Time for a Boost

Oceans, 2022
Coastal protection, an important coral reef ecosystem service, is threatened by increasing coral mortality, exacerbated by global climate change. Nature-based solutions in the form of coral restoration, while not perfect, can assist in rebuilding reef ...
