1 Monthly Report: June 2017 BARUCH INSTITUTE OF COASTAL ECOLOGY AND FOREST SCIENCE Highway 17 North PO Box 596 Georgetown, SC P (843) F (843) To: William Bailey, Mary Richards, and Nathan Dayan US Army Corps of Engineers - Savannah District 100 W. Oglethorpe Ave. Savannah, GA By: Jamie Duberstein USACE Savannah District: Please see the bulleted list below for the major actions and accomplishments associated with Cooperative Agreement Number W912HZ (Modification Number P00003) for the month of June Please let me know if you would like me to elaborate on the details of any items I ve listed below, or if there are any status updates you d like on unlisted topics. Thank you, Jamie June 2017 Report, p.1

2 Marsh Vegetation The June synoptic vegetation samples were collected on 24 & 25 June, Transport to cold storage in Georgetown (SC) was 25 June. Sorting and counting began the next day, and was finished within the week. Sorted samples were placed in drying ovens for desiccation, in preparation for biomass measurements. Water Data Data from all water sensors were downloaded on 13 and 14 June. An updated salinity table is provided (Table 1). There haven t been any data losses since January o See Table 2 for a complete list of salinity data losses thus far for FY17. All aboveground sensors (Aquatroll 100s), plus the belowground sensor at Swamp 2, were cleaned and calibrated immediately after data were downloaded. This completes the annual calibration for all sensors within the monitoring sites. A spot check of belowground salinity conditions were measured using a YSI Pro30 handheld salinity meter during the June sensor download. Salinity values were compared to those measured via Aquatrolls (Table 3). o There was notable difference (3 psu) between autonomous versus hand-held sensor at Back 4. We will note this and compare again in July; 0.2 PSU seems low at Back 4. The telemetry unit used for real-time data access was deployed on 08 June :00. It transmits data from the belowground sensor at the Back 3.5 monitoring area. o Raw data and graphical representation can be accessed online at hydrovu.com using username and password. o Data are still stored within the deployed Aquatroll sensor, and can be downloaded as usual. Forest monitoring Monthly measurements of baldcypress tree growth were last taken on 14 June at the swamp monitoring areas. Average basal area increase since last measurement: o Swamp 1: 1.9 cm 2 (25 May 14 June) o Swamp 2: 1.7 cm 2 (25 May - 14 June) o Swamp 3: 0.4 cm 2 (25 May - 14 June) June 2017 Report, p.2

3 Herpetofauna (MS student) study The 2017 field data were collected between 01 March and 14 June. The 2016 field season spanned 01 March thru 31 May. This was the second and final field season for this component. Data are entered and analyses are underway. They will ultimately be written up into thesis format. June 2017 Report, p.3

4 Table 1. Fiscal Year 2017 average, minimum, and maximum salinity (psu: practical salinity units) measured via sensors at above- and below-ground locations at (12) marsh monitoring areas and (3) tidal forest areas. Summaries are based on hourly measurements starting 01 October 2016 through 13 June 2017 for all monitoring areas unless noted by superscript; details of data losses are provided in Table 2. Measurements taken during dry well conditions were removed from calculations of summary statistics.

12 Table 2. Summary of FY17 salinity data losses from Aquatroll sensors deployed at SHEP monitoring areas between the dates of 01 October June Data loss periods and number of days may include periods within FY16. Minor data losses were incurred when data were downloaded near pre-programmed sensor measurements. Water level data losses may be beyond dates listed below. Data loss period Area Position Beginning End # Days Reason Middle 1 Aboveground 09/28/ :00 10/20/ : Circuit board failure Middle 4 Belowground 10/09/ :00 10/20/ : Circuit board failure Back 3 Belowground 11/06/ :00 11/06/ : Sensor fouling Back 3 Belowground 12/07/ :00 12/09/ : Sensor fouling Back 3 Belowground 12/15/ :00 12/17/ : Sensor fouling Back 3 Belowground 12/29/ :00 12/29/ : Sensor fouling Back 3 Belowground 01/17/ :00 01/27/ : Sensor fouling Table 3. Comparison of belowground salinity measurements taken June 2017 via autonomous sensors (In-Situ Aquatrolls) versus a "spot check" measured via handheld YSI salinity meter (units: parts per thousand = ppt). Reports typically provide summaries of hourly Aquatroll measurements of salinity as practical salinity units (psu) though measurements of total dissolved solids as parts per thousand (ppt) are also collected. Here we report both Aquatroll measurements to facilitate comparisons with handheld YSI measurements. Accuracy of the handheld YSI meter is 0.1 (ppt), while accuracy of the Aquatrolls is (psu, ppt); Aquatroll values were rounded to the nearest 0.1 to facilitate comparisons.
