fDOM Dataset Description: Methods and Sampling: <p><strong>fDOM fluorometry sampling:</strong><br />
fDOM concentrations at S2 and S8 were evaluated using Wetlabs FLCD shuttered fluorometers sampling at 15 minute intervals. The deployment scheme for the FLCD units was identical to that for the YSIs. The YSIs, fDOM (and chlorophyll) fluorometers were swapped out on the same schedules. At S2, the fluorometers were also mounted below the “moon pool” of the floating dock and were ~ 1m from the YSIs. At S8, they were collocated on the bottom frame with the other instruments.</p>

Tempo and mode of salt marsh exchange
<p><em>Description from NSF award abstract:</em><br />
Salt marshes are critical mediators of the flux of material between the terrestrial and marine realms. The balance of material import, export, and transformation affects both the marsh itself and the surrounding estuary. Previous efforts to understand the role of marshes have concentrated either on examining temporal changes (often at low resolution) of bulk exports, or compositional changes in exported material with little regard for its temporal variability. Researchers working at the Skidaway Institute of Oceanography contend that both the quantity and quality of materials exchanged between marsh and estuary in tidally-dominated systems along the southeastern US coast vary significantly in response to semidiurnal, diurnal, tidal, meteorological and seasonal forcing, and that this variability must be included when considering the total contributions of marshes to carbon cycling along the land-ocean boundary. This study will utilize a three-pronged strategy to assess both the quantity and quality of dissolved organic matter (DOM) and particulate organic matter (POM) exported from Groves Creek, a well-characterized meso-tidal salt marsh in coastal Georgia. In particular, by evaluating how marsh function responds to a full spectrum of present environmental conditions, this project will provide tangible insight into how carbon cycling in these critical regions will respond to anticipated changes in those conditions.</p>
<p>This project is related to the project "Marine priming effect - molecular mechanisms for the biomineralization of terrigenous dissolved organic matter in the ocean" found at <a href="https://www.bco-dmo.org/project/554157">https://www.bco-dmo.org/project/554157</a>.</p>

<p><strong>fDOM fluorometry sampling:</strong><br />
fDOM concentrations at S2 and S8 were evaluated using Wetlabs FLCD shuttered fluorometers sampling at 15 minute intervals. The deployment scheme for the FLCD units was identical to that for the YSIs. The YSIs, fDOM (and chlorophyll) fluorometers were swapped out on the same schedules. At S2, the fluorometers were also mounted below the “moon pool” of the floating dock and were ~ 1m from the YSIs. At S8, they were collocated on the bottom frame with the other instruments.</p>
Specified by the Principal Investigator(s)
<p>Raw fDOM fluorescence output (counts) have been manipulated three ways:</p>
<p>Counts were converted to fDOM ppb quinine sulfate equivalents (QSEs) using the manufacturer calibration data provided for each unit.</p>
<p>Data were corrected for quenching of fluorescence at higher temperatures. Lab experiments showed that fluorescence of a given source water declined linearly by ~20% between 20-40C. A pooled regression correction was applied to all units to compensate for the lowered fluorescence response at higher temperatures. All fluorescence data are normalized to fluorescence at 20C.</p>
<p>Fluorescence offsets (as QSEs) between units during successive deployments were corrected using a multi-step procedure</p>
<ul>
<li>Obvious bad data were excised from the records</li>
<li>Each individual deployment output was smoothed using a weighted 8 point local regression routine (Matlab ‘rloess’) to suppress spiky outliers.</li>
<li>Each fluorometer output was then adjusted up or down based on their mean intercalibration and deployment overlap offsets to bring them all in rough alignment.</li>
<li>The mean of the residual overlap gaps for each successive deployment was determined, and a Matlab pchip spline was applied to connect those points.</li>
<li>Each deployment record was made to conform to the spline curve fit so that the overlapping endpoints had a mean difference -&gt; 0 and possessed a smooth transition between successive deployments.</li>
<li>The concatenated data file was linearly interpolated onto a 10 minute time vector to facilitate intercomparison of records.</li>
<li>No attempt to date has been made to correct the fluorescence data for quenching due to turbidity in the water column.</li>
</ul>
<p><strong>BCO-DMO Processing notes:</strong><br />

- modified parameter names to conform with BCO-DMO naming conventions<br />
- added station, lat, lon, date, time, ISO_DateTIme columns<br />
