REMARK: Update to newer name per the diatom taxonomic coordinator
IN 5 CHANGE SYSTEMS AS TARGET:
22 NAWQA 1997- to 2001-Start tax. system, diatoms (csat_id: 3615)
from: Navicula exigua var. signata (NADED 93152)
to: Navicula exigua var. signata (NADED 46541)
REMARK: Added during queue of WMIC data
In correctional change system(s) as TARGET: More...
46 White River Diatometer 2003-2004 (csat_id: 4088)
