Field Activity 2024-004-FA

Identifier	2024-004-FA
Alternate names	Marsh Island New Bedford 2024 - CED/AIM/EG
Purpose	Monitor the hydrodynamics and sediment supply to a newly engineered system. Buzzards Bay Coalition and their partners have just completed Phase I of this project to create an engineered salt marsh on a former fill area. Sediment supply is a key factor in salt marsh sustainability with rising sea-level, this site provides a unique opportunity to study the establishment of the engineered system under the natural forcing of the tides and water flow.
Location	Marsh Island site New Bedford Harbor, Acushnet River, Fairhaven, MA..
Info derived	Time-series data of water level, currents, flow/discharge, waves, turbidity, and other water-quality parameters (temperature, salinity, chlorophyll, dissolved oxygen, pH, fDOM, blue-green algae). Supplemental water samples will be collected and analyzed for total suspended-sediment concentration and loss-on-ignition. Grain-size distribution will be determined from sediment samples collected the marsh creek bed. Aerial mapping will provide full elevation coverage and multispectral orthoimage data. Biochem time-series sensor data are groundwater well CTD measurements.
Comments	This will be an ongoing study and would like it to be an event type field activity. Multiple Information specialists due to group overlap. Entries for this field activity are based on entries from Field Activity 2023-025-FA.
Projects	Estuarine Processes, Hazards, and Ecosystems ?mid-Atlantic Biochemical Processes & Budget Aerial Imaging & Mapping (AIM)
Platform	on foot survey conducted on foot
Itinerary	Start Fairhaven, MA 2024-01-23 End Fairhaven, MA 2024-12-31 Days in the field 10 Activity events Hide Start date End date Description 2024-01-23 2024-01-23 Bo and Olivia turned around the Dwave, Exo, and IQ 2024-04-09 2024-04-09 S. Brosnahan and S. Ackerman visited site with UAS equipment and flew the M600 YellowScan Mapper+ (lidar and RGB camera) attached. Mavic and Anafi might be flown too. AeroPoints were deployed as ground control. 2024-04-22 2024-04-22 Jen O'Keefe-Suttles, Emily Tacke, Jin-Si Over, and Robert Bales visited the site. Wells were sampled and checked, the Exo and IQ under the bridge were serviced and replaced. Base station occupied the new PK nail on the bridge and the RTK equipment was used to take a transect across the channel and on the equipment. 2024-05-21 2024-05-21 Bo and Olivia connected IQ to new battery, downloaded data, changed "Record Multicell Data" setting to 1, and restarted data collection. 2024-05-22 2024-05-22 Swap well loggers, download barometer, surface water collection. Emily Tacke and Dakota Sievers 2024-06-20 2024-06-20 Tidal creek tidal sampling. Meagan Eagle Amari Johnson 2024-06-24 2024-06-24 Bo and Olivia turned around the Dwave, Exo, and IQ. 2024-06-25 2024-06-25 Tidal creek tidal sampling. Emily Tacke, Amari Johnson 2024-07-02 2024-07-02 Bo, Jen C, Seth, Amari (student), and Ezra (volunteer) did two sUAS flights with the Skydio X10 for a MIR aerial imagery data collect for photogrammetry. A GPS ground survey with the SP80 was also done. 2024-07-12 2024-07-12 Water sampling from bridge over the timeseries instruments on same interval as Exo. Water samples will be filtered for SSC and used to convert Exo turbidity (NTU) to SSC (mg/l). Personnel: Bo and Olivia 2024-07-19 2024-07-19 Tidal creek tidal sampling for geochemical constituents. Meagan Eagle Amari Johnson 2024-08-21 2024-08-21 S. Ackerman, J. Cramer, J. Over, M. Bartlett visited site with UAS equipment and flew the M600 with YellowScan Mapper+ (lidar and RGB camera) and the Altum (multispectral camera) attached. Also flew the new Skydio x10 (RGB and thermal camera). Mavic and Anafi might be flown too. AeroPoints were deployed as ground control. This fieldwork day was coordinated with researchers from the Buzzards Bay Coalition who are in the field this week doing vegetation and elevation surveys. 2024-09-17 2024-09-17 Bales and De Meo working at site under pedestrian bridge. Switching out dWave and Exo, downloading data from IQ and re-deploying. Collecting RTK data on new instruments and across the channel for IQ flow calculations. 2024-09-30 2024-09-30 Tidal creek tidal sampling. RTK wells. Retrieved well CTDs and barometer. Emily Tacke, Rachel Einecker 2024-10-15 2024-10-15 Change batteries and power setting on deployed IQplus. This should allow for longer deployments (up to 6mos). Steve Suttles and Bo Bales.
