Summary of Data Collection Campaign & Setup
- This dataset contains data collected during mangrove-mudflat campaign in Guyana, as part of Uwe Best's PhD Thesis project. 
- It is being made public both to act as supplementary data for publications and the PhD thesis of Uwe Best and in order for other researchers to use this data in their own work.
- There were a total of six deployments, each with varying durations, and spanned the period from November 22nd, 2019 to January 11th, 2020. 
- Eight frames were installed along the main transect,consisting of scaffolding pipes and connectors. 

All locations are described below: 
- MB 1: relative dense forest in the back of the mangrove 23 m away from the edge of the toe of the concrete dyke (sea wall).
- MB 2: approximately 100 m from the toe of the seawall within the mangrove.
- MB 3: approximately 200 m from the toe of the seawall within the mangrove fringe.
- MB 4: the seaward edge of the mangrove fringe.
- MB 5, 6, 7, 8: the mudflat in front of the mangrove, 1620 m seaward.

Software Needed
The processing of this data requires the use of MATLAB and Microsoft Excel.

***Short Decription of Data***

1. Wave Data: 

- This includes both the raw and processed data acquired by the six (6) pressure transducers (PTs) and the two (2) Acoustic Doppler Velocimeters (ADVs).
- The sampling frequency of the pressure transducers was set to 5 Hz to collectwater levels and allow for the extraction of both infragravity waves, and wind-generated waves via a MATLAB script. 

- The processed folders contains the water level data as well as the wave parameters (surface elevation spectrum Es1, zeroth-order moment m0, significant wave height Hm0, 
high frequency wave heights Hm0_hi1, low frequency wave heights Hm0_lo1, mean wave period Tm0, water depth h1, pressure p1, time t, Variance var, Infragravity wave height IG, 
Swell wave heights SW, Variance Spectrum, Frequency, Energy Spectrum).

- The raw data folder contains the files exported from the pressure tranducers.
- README file contains additional detail on the structure of the data.

2. Soil Properties:
- Soil samples are collected at all measurement locations, from the top layer (<2cm) of the soil. In addition to conducting a particle size analysis, the organic matter content is analysed.
- Along the transect, measurements for the sediment properties will be taken regarding the dry and bulk density, grain size, water content and Atterberg limits. 
- These values will filter into the parameters for the numerical model using Flexible Mesh and SWAN.
- README file contains additional detail on the structure of the data.

3. Mangrove Data
-For the mangroves, 10 m x 10 m quadrants were established along the eleven transects in the mangrove and were spaced at 30 m. The diameter was measured at stipulated heights: 0.1m , 0.5m, 1m , 1.5m, 2m 
and at breast height, 1.3m. The overall height of the tree was also recorded. For the seedlings, a 1m x 1m quadrant was used at three random locations to count the number of seedlings and pneumatophores, 
and determine their height and diameter. Salinity and temperature readings were taken at three (3) randomly spaced points within the quadrant.

 - README file contains additional detail on the structure of the data.

I. File Name: VEG_Data.xlsx

- Vegetation properties (density,tree height, root diameter and density, diameters [0.1m , 0.5m, 1m, 1.3m, 1.5m, 2m], salinity, temperature and number of seedlings) for both Black and White mangroves. Black mangroves are
the Avicennia germinans, while the White mangroves are the Laguncularia racemosa. Vegetation properties are expressed per 100 m2 along quadrants established along eleven transects.

- File are in .xlsx format. 

4. Concentration Data
- Suspended sediment concentrations were collected using the optical backscatter sensor which were validated using field water samples. Standard turbidity data in NTU values may then be calibrated to suspended sediment 
concentration (mg/l) using suspended sediment concentration data determined from the filtration of water samples. 

- For this campaign, two OBSs were used, T9012 and T9011. Both were tested and calibrated prior to use by Nortek. However, during the calibration process, T9011 malfunctioned. As such the T9012 was used to test both 
sediment samples (within the mangrove & on the mudflat), after which the relation dictated by the calibration certificate (for the respective instrument) were be applied.

- (Deployment 1 (D1), Deployment 2 (D2),Deployment 3 (D3),Deployment 4 (D4), Deployment 5 (D5)); Instrument locations are aligned with the descriptions in the data paper. Files are in .mat format. 

III. Main_Calibration_files
- The suspended sediment concentration (SSC) can be calculated with the Volts, an analog output from the ADVs. This is a two-step process whereby the ADV and OBS are connected  and setup to the frame in the laboratory. 
- With this, the counts are recorded for each addition of sediment added to the calibration vessel and this is converted to NTU values. 
- The second part of the process entails the determination of the concentration (g/l) using the filtration procedure.

I. Field_2020_data

Summary, 2020;  File Format: .xyz
- Coverage includes within the mangroves and on the mudflat. Within the mangroves, a combination of traditional surveying techniques were used with the automatic level and theodolite. Within the mangroves, 
limited satellite coverage prevented the use of the DGPS. A permanent bench mark (PBM) was established at the base of the earthen embankment. This PBM was then used to establish the eleven transects along 
the field area (1000 m x 3500 m). 

- Along the mudflat, the depths were attained using an echo sounder.  boat itself. These measurements were taken over four days to complete ten (10) transects. Due to the shallow water depths expected between 
1- 5 m, the single beam echo sounder gives quite accurate results and offers significant cost saving over the multi-beam versions.

- Surveyed depths were relative to Guyana Datum (GD) but these were converted relative to mean sea level (MSL). GD is 13.76 m below Chart Datum (CD), Ref: Guyana Tide Tables, 2004. MSL is 1.8 m above CD and 
15.56 m above GD in Georgetown.

II. GEBCO_data

Summary Historic Bed Levels;  File Format: .xyz

2004
- In November/December 2003 lines were surveyed with a spacing of 2 km (in offshore blocks). In May/June 2004 the intermediate lines were surveyed. The measured depths were corrected using measured water levels at Georgetown.

The General Bathymetric Chart of the Oceans (GEBCO) Gridded Bathymetric Datasets, 2004, 2008,2019

- The bed level measurements were supplemented by the global bathymetric charts. A timeline was then developed which spanned the mudbank cycle along the Guyana coastline, approximately 20- 30 years.
