#MarinePlastics, pieces both big and small, are an ongoing ocean conservation issue. There are #OceanOptimism solutions though, and we discuss those as well in our overview. https://ocean.si.edu/conservation/pollution/marine-plastics">https://ocean.si.edu/conservat...
#ClimateChange drives #SeaLevelRise. This overview covers the complexities like why some areas of the ocean will see more or less and the reasons behind the rise. https://ocean.si.edu/through-time/ancient-seas/sea-level-rise">https://ocean.si.edu/through-t...
The #GulfOilSpill occurred 10 years ago this month. We look at the impacts on the ecosystem, and research that has happened since in this overview. https://ocean.si.edu/conservation/pollution/gulf-oil-spill">https://ocean.si.edu/conservat...
With their roots submerged in water, mangrove trees thrive in hot, muddy, salty conditions that would quickly kill most plants. More about how they survive in this overview. https://ocean.si.edu/ocean-life/plants-algae/mangroves">https://ocean.si.edu/ocean-lif...
Hurricane season officially starts June 1 in the Atlantic.
