During the last week I had hoped to read the marine biology paper I referenced early in the summer but with the start of the semester, COVID, etc.</div>

I did have one point to add and that is effort is not usually reported in Biodiversity database but it is computed for four pieces of information</div>

<div>Perhaps it is sufficient for the standard just to say the variables to necessary to compute effort are available.</div>
<div>Perhaps that could be checked by machine when data are deposited and a flag set.</div>

<div>Hope the meeting is productive.</div>
