The beach near the apartment in St Croix- looking one way...

Thanks to Wikipedia I have compiled some relevant aspect about the source of the seaweed....
The Sargasso Sea is a region in the middle of the North Atlantic Ocean, surrounded by ocean currents. It is bounded on the west by the Gulf Stream; on the north, by the North Atlantic Current; on the east, by the Canary Current; and on the south, by the North Atlantic Equatorial Current. This system of currents forms the North Atlantic Subtropical Gyre. All the currents deposit the marine plants and garbage they carry into this sea.
The Sargasso Sea is 700 statute miles wide and 2,000 statute miles long (1,100 km wide and 3,200 km long). It stretches from roughly 70 degrees west to 40 degrees west, and from 25 degrees north to 35 degrees north. Bermuda is near the western fringes of the sea. The Sargasso Sea is the only "sea" without shores. The ocean water in the Sargasso Sea is distinctive for its deep blue color and exceptional clarity, with underwater visibility of up to 200 feet (61 m).

...looking the other way

 The Sargasso Sea is home to seaweed of the genus Sargassum, which floats en masse on the surface there. The sargassum is not a threat to shipping, and historic incidents of sailing ships being trapped there are due to the often calm winds of the horse latitudes.

A huge chunk of the Sargasso seaweed was torn off during the hurricane...

 Owing to surface currents, the Sargasso accumulates a high concentration of non-biodegradable plastic waste. The huge North Atlantic Garbage Patch is similar to another ocean phenomenon, the Great Pacific Garbage Patch.

It was in evidence on all flights to and from St Croix

From above I think it made for pretty pictures!
