Sedimentary and hydrodynamic measurements in the Ayeyarwady River Delta from 2017-01-01 to 2019-10-31 (NCEI Accession 0216705)

This dataset consists of in-situ hydrodynamic, meteorological, and geological measurements from the Pathein, Bogale, and Yangon distributaries of the Ayeyarwady River, Myanmar in 2017-2019. None of the data to be archived has been altered since collection. The data falls into four categories:

Fixed Instrumentation: Instruments that were installed in a single location for the entire sampling period. The variables measured include water turbidity, water temperature, water salinity, water pressure, air temperature, air pressure, wind speed and direction, Photosynthetically available radiation, humidity, and rainfall collected at 10 minute intervals semi-continuously in 2017-2019. All of the data is available as both csv and raw instrument files.

Surveying Data: Data collected during boat-based surveys periodically throughout the study period. The variables measured include water turbidity, temperature, salinity, pressure, and velocity. Data was collected during daylight hours transiting either along a river or across a single transect of a river.

Samples processed in the laboratory: Data produced by laboratory analysis of physical samples collected periodically during boat-based surveys. The variables measured are sediment grain size and suspended-sediment concentration.

GPS and Logbooks: Field notes and GPS points created during the study period which support the above data.
