Summary: The video displays the growth and spread of a Karenia Mikimotoi harmful algal bloom along a coastline from March to June 2025, showing changes in intensity over time.
This animation illustrates the dynamic changes in a Karenia Mikimotoi bloom, a type of harmful algal bloom (HAB), off an unidentified coastline from March 4, 2025, to June 2, 2025. Initially, a faint bloom is visible, gradually intensifying and expanding into a coastal bay area through April and early May, reaching peak intensity with widespread red areas. By late May and early June, the bloom begins to disperse and spread across a much larger oceanic region, with varying but generally lower intensity, though pockets of higher concentration persist.

1. time: 00:00 label: Initial bloom detection on Mar 4, 2025. Sparse, low-intensity blue areas appear off the coast. A legend for Karenia Mikimotoi Bloom Intensity is visible. 2. time: 00:01 label: Bloom on Mar 19, 2025. The bloom has expanded and intensified, particularly in a coastal bay, showing yellow and orange colors. 3. time: 00:02 label: Bloom on Apr 1, 2025. Further growth and intensification, with significant red areas in the bay. A label 'Harmful Algal Bloom' appears, pointing to the affected area. 4. time: 00:03 label: Bloom on Apr 11, 2025. The bloom continues to grow in size and intensity, with more widespread red and orange patches. 5. time: 00:04 label: Bloom on May 5, 2025. The bloom reaches its peak intensity and geographical spread, heavily concentrated in the bay and surrounding coastal waters with dominant red colors. 6. time: 00:05 label: Bloom on May 20, 2025. The bloom begins to dissipate in its core but spreads out widely into the ocean, covering a larger area with lower, bluer intensity, though red patches remain. 7. time: 00:06 label: Bloom on May 31, 2025. The bloom is highly dispersed across a vast oceanic region, showing varied intensities from blue to yellow. 8. time: 00:07 label: Bloom on Jun 2, 2025. Similar widespread dispersion as May 31, with a large footprint but less concentrated intensity in any single area.
