Where necessary, assumptions of linearity, normality, homoscedasticity,
independence and randomness will be assessed prior to proceeding with analyses to
ensure that statistical test are being used appropriately.
Phase 2
Data analysis in Phase 2 will consist of two parts. The first set of analyses will be
to compare annual predictions of 14 C based primary production made by the ELZ model
with those collected in the field. The comparison will provide and indication of the
model’s validity and utility as well as provide a means to annually refine the model’s
predictive power with new data. The analysis and modelling exercise will employ the
same analytical tools as used in Phase 1 of the monitor.
Primary productivity estimates based on 14 C inoculation will be analysed for
trends with the accrual information. This analysis will lead to the development of a
calibration curve that will best predict primary production from the AFDW accrual data.
The littoral estimates of primary production (accrual based) will then be combined with
pelagic values to estimate overall productivity of each reservoir as per Wetzel (2001).
The data collected during this phase of the monitor will provide the first indication of how
the tests of H06 and H07 will likely turn out.
The other component of the analysis will be to annually track the ratio of littoral to
pelagic primary productivity in each reservoir, and hence test hypotheses H06 and H07 in
a repeated measure framework. The test will be carried out each year of the monitor so
as to track the likelihood of change over time.
As in Phase 1, assumptions of linearity, normality, homoscedasticity,
independence and randomness will be assessed prior to proceeding with analyses to
ensure that statistical test are being used appropriately.
2.3.5 Reporting
At the end of each year of the first phase of the monitor, a data summary will be
prepared that document the year’s findings. At the conclusion of the Phase 1, two
reports will be prepared, the first of which summarises the data collected to date. The
second report will present and discuss the results of all hypothesis tests, as well as
present conceptual and numerical models of littoral primary productivity. Both reports
will be submitted to the Management Committee for review before being finalised for
general release.
During Phase 2 of the monitor, annual data reports will be prepared that
summarise the year’s findings, including a discussion of the year’s data relative those
collected in previous years and the likelihood of an increasing or decreasing trend.
Unlike Phase 1, the Management Committee will review all annual reports before being
finalised for general release.
At the conclusion of the monitor, a comprehensive report will be prepared from
the Phase 1 reports and all of the annual data reports that:
