Background and summary
Editors and participants
Workshop report descriptions
Additional information
To help support the accuracy, quality and consistency of algal analysis, the USGS
NAWQA program supported one or two taxonomic workshops per year from 1999 to 2008.
Typically, one was focused on diatoms and one on non-diatoms (soft-algae). Participants
included persons analyzing NAWQA algae samples, outside taxonomic experts, and guests
involved with other algae monitoring programs (see lists below). The overall purposes
of the workshops were to develop common sets of names and concepts to be used
by all analysts, to discuss and resolve taxonomic issues within difficult algal
groups, and to review NAWQA algal data and general taxonomic issues. The workshops
focused on taxonomic issues related to NAWQA samples, and were primarily for the
benefit of NAWQA algal analysts. However, participants recognized that the information
in the reports contain much information of use and interest to other phycologists,
so they are made publically available. The reports have not been peer-reviewed other
than by workshop participants. All workshops except one were held at the Academy
of Natural Sciences.
The 17 reports completed as of January 2010 have a total of 1600 pages and contain
2486 figures on 281 plates. All reports are available as pdf files (see links above).
The descriptions below summarize the main subjects and contents of the reports.
Click on "[Introduction]" at the end of each description to see the first few pages
of each report that provide more detailed information, including names of authors
and participants. The index
to the reports is very useful for finding images and discussion of individual taxa.
It lists taxon name, report number and figures, plates, and page numbers with images.
All diatom workshop reports are indexed; soft-algae report indexing is ongoing.
Note that in some reports the figures are not formally organized as "plates."

NADED = North American Diatom Ecological Database. All ANSP Phycology Section algal
count data are stored in this database. Taxa names used in the database have a unique
identification number (NADED ID).
Explanation of "XXXX-start taxonomy. The NAWQA Cycle I design divided study units
(major watersheds) into three groups. Research on the three groups started at three
year intervals, one set in 1991, one in 1994, and one in 1997. Each group was commonly
referred to as a "start" (e.g., 1991-start). Sample collection began two years after
the initial start date (see below). This same pattern continued in Cycle II, though
NAWQA discontinued the "start" terminology. Algae taxonomy was typically kept constant
for analysis of all samples part of each "start". For example, "1997-start taxonomy"
refers to the set of algal names used for samples collected as part of the 1997-start
samples. Taxa names were updated every three years to correspond with the beginning
of each new start.
Cycle I
NAWQA 1991-start samples - collected 1993 - 1995
NAWQA 1994-start samples - collected 1996 - 1998
NAWQA 1997-start samples - collected 1999 - 2001
Cycle II
NAWQA 2001-start samples - collected 2002 - 2004
NAWQA 2004-start samples - collected 2005 - 2007
NAWQA 2007-start samples - collected 2008 - 2010
Several workshop reports include recommendations for changes that should be made
in past counts either to correct perceived misidentifications, or to update names
to to current synonyms. Few of these changes have been made in the NADED or NAWQA
databases, though they have been incorporated in files used for data analysis.
