Fished conch shells in modern heaps noted in 2012 to 2018 that were largely reshaped by storm waves offshore Anegada, British Virgin Islands
This part of the data release catalogs 40 offshore conch heaps mapped on airphotos and satellite images. Conch shells harvested around Anegada since the start of European colonization, which began late in the 18th century C.E., have been discarded in piles south of the southeastern part of the island, in the Caribbean Sea. Storm waves have notched some of these heaps and have flattened others. The catalog is based on interpretation of airphotos taken 2002 and of satellite images, accessed on Google Earth, taken in 2011–2019. Some of the offshore heaps were observed by boat in 2012, 2015, 2017, and (or) 2018. Repeat visits provided evidence for beveling during the hurricane season of 2017.
