They should be able to map the strewn field and propose a location for the impact and see if it under water or not.
Reguardless of whether it is underwater or on land, if a large crater is indeed associated with young dryas event, that crater would be the youngest, and thus the most prestine and least eroded, most conspicuous large crater we ever found, provided we know where to look.
If the propose point of impact is indeed under water, it would introduce more room for falsifiable predictions and bounding constraints. For example, impacts in deep ocean would tend to inhibit the formation of strewn fields, so if iproponent thinks it hit deep sea and still made an enormous strewn field, then the lower limit on its size would increase dramatically. Now we expect an object not hundred of meters across but kilometers across. We would also expect to see megatsunami deposites on all adjacent shores from impact of such a massive object.
