2. Abstract: Conductivity, temperature and pressure were measured continuously at Georgia
Coastal Ecosystems LTER sampling location GCE3_Hydro (Sapelo Sound north of Sapelo Island,
Georgia) from 01-Jan-2016 through 31-Dec-2016. Observations were logged at 30 minute
intervals by moored Sea-Bird Electronics MicroCAT 37-SM data loggers and downloaded
approximately semi-monthly. Salinity, depth and sigma-t (density anomaly) were calculated
from the measured parameters using standard UNESCO algorithms. This data set was collected
as part of the GCE-LTER Project continuous salinity, temperature and water level
monitoring program.

4. Objectives: The research proposed for GCE-III is designed to address how variations in
salinity and inundation, driven by climate change and anthropogenic factors, affect biotic
and ecosystem responses at different spatial and temporal scales, and to predict the
consequences of these changes for habitat provisioning and carbon (C) sequestration across
the coastal landscape.
5. Abstract: The Georgia Coastal Ecosystems (GCE) LTER is located along three adjacent sounds
on the Atlantic coast and includes both intertidal marshes and estuaries. Long-term
drivers of climate change, sea level rise and human alterations of the landscape will
cause transitions in dominant habitat types (state changes) within the GCE domain by
changing the amounts and patterns of water delivery across the landscape. These changes in
water delivery can be conceptualized as presses and pulses in river inflow, local runoff,
groundwater input, and tidal inundation, which will in turn manifest themselves as changes
in salinity and inundation patterns in the domain. The research proposed for GCE-III is
designed to address how variations in salinity and inundation, driven by climate change
and anthropogenic factors, affect biotic and ecosystem responses at different spatial and
temporal scales, and to predict the consequences of these changes for habitat provisioning
and carbon (C) sequestration across the coastal landscape. The goals are to: 1) Track
long-term changes in climate and human actions in the watershed and adjacent uplands, and
evaluate the effects of these drivers on domain boundary conditions. 2) Describe temporal
and spatial variability in physical, chemical, geological and biological, and to evaluate
how they are affected by variations in river inflow and other boundary conditions. 3)
Characterize the responses of three dominant habitats in the domain to pulses and presses
in salinity and inundation. 4) Describe patterns of habitat provisioning and C
sequestration and export in the GCE domain, and to evaluate how these might be affected by
changes in salinity and inundation. These efforts will be synthesized into a synoptic
understanding of both biotic and ecosystem responses to variations in salinity and
inundation driven by climate change and human activities, which will be used to assess
thresholds between habitats and the potential for state changes in the domain.

monitored using an autonomous data-logging sensor package (sonde) that was moored to a
piling and submerged 1-1.5m below mean low water.
b. Permanent Plots: none
c. Data Collection Duration and Frequency: The MicroCAT was programmed to autonomously
measure and log conductivity, temperature and pressure at a sampling rate of 30 minutes
(based on its internal chronometer). Upon retrieval the data was downloaded from the
instrument via RS-232 serial communications and processed using custom Matlab(r)
procedures to calculate depth (i.e. from pressure and latitude), salinity and sigma-t
(i.e. from conductivity and temperature), and date and time components from sample time
stamps.
Beginning of Observations: Jan 01, 2016
End of Observations: Dec 31, 2016
3. Research Methods
a. Field and Laboratory Methods:
Method 1: Deployment -- The MicroCAT was mounted inside a protective PVC pipe enclosure
and attached to a wooden piling (~12 inch diameter) that was driven firmly into the
substrate. The enclosure was constructed from a 10-foot length of 6-inch (internal
diameter) PVC pipe that was perforated all over by drilling 1.5-inch holes (at
approximately 4-inch spacing); this permits proper water circulation within the
enclosure. The bottom of the PVC pipe was submerged about 5 feet below the water
surface at low tide and bolted (vertically) to the piling. The MicroCAT was deployed
by lowering it into the enclosure on a 0.375-inch stainless steel cable, and bolting
the cable to the piling, so that the bottom of the data logger was ~3 inches above
the bottom of the PVC pipe. A weighted surveyor's tape was then used to measure the
distance from the substrate to the pressure sensor on the MicroCAT for calculation
of total water column depth from pressure readings. The mooring was inspected every
1-3 weeks, and any visible fouling of the enclosure or MicroCAT was removed with a
brush or scaper.
Method 2: Retrieval and Calibration -- At the end of each measurement period
(approximately 2 months), the MicroCAT was unshackled from the cable and returned to
the laboratory. The stored data was uploaded to a computer using a RS-232 serial
cable and Sea-Bird Electronics SEATERM software. The MicroCAT was then cleaned to
remove encrusting material and calibrated with a reference instrument at 4 to 5
salinity levels, generally ranging from 30 to 5 PSU.
Method 3: Data Processing -- Data were processed after each retrieval using custom
programs in the GCE Data Toolbox for MATLAB (parse_37sm and imp_gcesonde). Depth was
calculated from recorded pressure and latitude values, and salinity and sigma-t were
calculated from recorded conductivity and temperature values using standard UNESCO
algorithms (reference: Unesco. 1983. Algorithms for computation of fundamental
properties of seawater, 1983. Unesco Technical Papers in Marine Science No. 44, 53
pp.). Data were then plotted and visually inspected for evidence of biofouling of
the conductivity sensor (i.e. prolonged periods of damped tidal oscillation in
conductivity signal with no corresponding changes in temperature signal and no wind
or rainfall events recorded at nearby monitoring stations, or periods of damped
oscillation immediately followed by normal oscillation after instrument maintenance
or replacement). Conductivity values recorded during periods of suspected biofouling
were flagged as I (invalid) if visible fouling was noted in maintenance logs, and Q
(questionable) if no visible fouling was noted.
Method 4: Daily Aggregation -- The finalized 30-minute resolution data set was filtered
to remove any remaining invalid values (i.e. assigned qualifier flags of 'I' =
invalid value or 'X' = excise row), then padded with empty rows to produce a
monotonic time series data set with even time steps. The data records were then
aggregated (grouped) by Year, Month, Day, Site, Longitude and Latitude, and relevant
summary statistics were calculated for each measured variable in each group and
added as data columns. Quality control rules were defined for each calculated column
to flag statistics based on days with more than 35% missing values as invalid, and
more than 10% missing values or 35% flagged values as questionable. Columns listing
the number and percentage of missing and flagged values in the original data set for
each day were also added as data columns for reference by quality control rules.
Following aggregation, summary statistics flagged as invalid were removed from the
daily-aggregated data set and converted to missing (NaN).
