Out to sea: ocean currents and patterns of asymmetric gene flow in an intertidal fish species

Frontiers in Genetics, 2023
Passive dispersal via wind or ocean currents can drive asymmetric gene flow, which influences patterns of genetic variation and the capacity of populations to evolve in response to environmental change. The mangrove rivulus fish (Kryptolebias marmoratus),

Particle System-Based Multi-Hierarchy Dynamic Visualization of Ocean Current Data

ISPRS International Journal of Geo-Information, 2021
In three-dimensional (3D) digital Earth environment, there are many problems when using the existing methods to express the ocean current, such as uneven distribution of seed points, density leap in scale change and messy visualization.
