cismas라고 해양 탐사를 하는 모임같은 곳에 대한 이야기인데요.
another project has discovered a large quantity of early 14th century french pottery in the tresco channel
-a narrow stretch of water between the islands of tresco and brhyer.
work is ongoing to analyse the site and what it has yielded, with the number of fragments found and the narrow time period and origin.

여기서 what it has yielded 를 어떻게 해석하나요?퓨ㅠㅠㅠ
