Dendrogram representing groups of monitoring activities based on three attributes of
data accessibility: monitoring guidance (i.e., whether a monitoring activity is
guided by a sampling protocol or monitoring design), machine readable (i.e., whether
data are readily available in a machine readable format), and reporting lag (i.e.,
time lag between data collection and data reporting). Numbers represent the number
of monitoring activities described by the combination of data attributes at that
Heat map showing concentrations of monitoring activities based on the Delta
regions and years for which data are represented. Increasingly darker cells indicate
a greater concentration of monitoring activities with data for that combination of
region and year.
Bar graph illustrating the level of involvement of different organizations
implementing, funding, or supporting the various monitoring activities
summarized in the monitoring inventory.
