Every year, several thousand, if not millions, of young seeds (Velella Velella) are washed away on the west coast of the United States. It’s not very strange considering that the jellyfish-like creatures are driven by the wind and can be easily stranded. However, scientists have rarely seen so much laundry as in recent years. This is the “point” error.
The English name (sailor jellyfish) bazantje betrays more than the Dutch name. The blue-violet jellyfish-like creatures are moved by the wind with a kind of tarpaulin and it is only a matter of time before they end badly for the hollow creatures. For example, after storms one sees tropical beaches full of dry seeds.
This happens every year in the regions they live in, but between 2015 and 2019 significantly more seeds were washed. This came according to a study whose results were recently published in the Official Gazette The series introduces the marine environment vakblad.
Researchers began working with data from COASST, a citizen science project that uses citizen scientists to monitor and count the number of seeds being washed away. This resulted in a dataset of 23,265 surveys spread over 293 different beaches in the United States.
Underwater heat wave
What turns out? Most of the seeds dry out during the spring. But what was particularly striking was the large number of cetaceans that washed ashore between 2015 and 2019. This may have something to do with “The Blob” or “De Klodder,” a huge mass of water that is too warm for the US West Coast.
This underwater heat wave might have played a role, but not in the way you might think. After all, the seeds thrive in warm water. As a result, more and more of these jellyfish-like creatures appeared: the more seeds, the more they were eventually washed ashore.
