[Coral-List] scotch brite sediment traps

Good day.

I have stayed out of this thread for some time, but feel compelled to jump in here.

One of the ongoing problems in coral reef research is the individual re-inventing of wheels. This is nowhere so well demonstrated as in the efforts (mostly of biologists) to "measure" sediments on reefs. Virtually every paper introduces a "new" technique, which gives the authors a few seconds' worth of warm fuzzies and ensures the results can never be applied anywhere else. Virtually no one cites the seminal work of Gardner, in which various sediment trap designs were evaluated (and many discarded).

The LAST thing we need here is yet another method.

I direct interested listers to Storlazzi et al. 2011, Coral Reefs 30: 23-38, on the use and mis-use of sediment traps in coral reef research.
