Infragravity energy fluxes at inner and outer swales of Shoal E

Variability of infragravity motions (between 1 and 50 mHz, or 20 and 1000 s) over cape-related shoals is not well understood. To compare the variation in bulk infragravity energy fluxes due to the presence of a shoal, observations of water velocity and near-bottom pressure were obtained from upward looking acoustic Doppler current profilers (ADCPs) at inner and outer swales of Shoal E, offshore Cape Canaveral, Florida Atlantic coast. Experiments were conducted during Fall 2013, Spring 2014 and Fall 2014. Pressure and velocity data were recorded in bursts of 1200, 2048, 2400, or 3600 data at 2 Hz. Pressure was measured ca. 1 m above the bed, whereas velocities were obtained at one depth, between 3 and 7 m above the bed. This collection also includes wave statistics (significant wave height, peak period, and peak direction), and infragravity energy fluxes.

Datasets in the Collection

These data relate to infragravity energy fluxes variability between landward and seaward swales of a cape-related shoal. Observations of water velocity and near-bottom pressure were obtained from upward looking acoustic Doppler current profilers (ADCPs) at inner and outer swales of Shoal E, offshore Cape Canaveral, Florida Atlantic coast. Measurements were conducted during Fall 2013, Spring 2014 and Fall 2014. Mean water depths during all deployments at eastern and western swales were ~13 and ~14 m, respectivley. Pressure and velocity data were recorded in bursts of 1200, 2048, 2400, or 3600 data at 2 Hz. Pressure was measured ca. 1 m above the bed, whereas velocities were obtained at one depth, between 3 and 7 m above the bed. This collection also includes wave statistics (significant wave height, peak period, and peak direction), and infragravity energy fluxes.
