Dataset for Manuscript: "Flow Structure and Mixing Near a Small River Plume Front: Winyah Bay, SC, USA"

Data set associated with the manuscript:

"Papageorgiou, C., Voulgaris, G., Yankovsky, A., and Fribance, D.B.: Flow structure and mixing near a small river plume front: Winyah Bay, SC, USA, EGUspere [preprint], https://doi.org/10.5194/egusphere-2025-189, 2025" submitted to EGU's Ocean Science.

All files are in MATLAB (*.mat) format. Times are in UTC presented as  a serial date number corresponding to the whole and fractional number of days from a fixed, preset date (January 0, 0000) in the proleptic ISO calendar (MATLAB datenum format). Each file includes a parameter called readme that provides information about the variables contained in the file.

For more information on the data packaged in the attached zip file (EGU_OS_data.zip) see the manuscript; a brief description of the content of each file is presented in the table below.
