1. Overview

This dataset contains raw data from field campaigns conducted in McKay Bay and Philippe Park (Tampa Bay, FL, USA), for the purpose of measuring changes in hydrodynamics across three shoreline types: (1) mangrove-vegetated, (2) non-vegetated with seawall, and (3) mangrove-vegetated with seawall. The measured absolute pressure and velocity time series files are provided for both project sites, as well as the recorded vegetation surveys. The absolute pressure was measured using Van Essen pressure transducers at 15-min intervals and the velocities were measured using Nortek Acoustic Doppler Current Profilers once every 2-min over a duration of 16 days at both "onshore" and "offshore" transect points. The transects were approximately 30 meters across shore. Files with "PT" in the name refer to measurements taken by Van Essen pressure transducers, while files with "ADCP" in the name refer to measurements taken by Nortek ECO Acoustic Doppler Current Profilers.

1. Description of transect surveys

This resource includes measurements recorded for two vegetation transect surveys (one for each study site). The associated files are: Philippe_Transect_Survey.xlsx McKay_Bay_Transect_Survey

For each survey, the circumference of mangrove roots and stems were taken at 10cm and 30cm above the ground (measured in cm) within a 1-m wide swath of a transect line spanning from the offshore transect point to the onshore transect point. Each sheet is for a different shoreline type (mangrove, hybrid, or seawall). These are the direct field measurements transferred from paper to spreadsheet. The height (m) of each new tree is noted as well as the species (RM = red mangrove, BM = black mangrove, WM = white mangrove). In the "Notes" row, the tree that the measurement refers to is noted (all circumferences with measurement "A" are from roots that are connected to the same tree). Each meter along the transect is also noted in the "Notes".
