Abstract:

This dataset includes CTD casts, GPS logs from drifter deployments, and accelerometer data from wave buoy deployments. These data were collected in the Gulf of Mexico near the Mississippi River delta during the SPLASH field campaign between April 19-27, 2017. The CTD was a YSI Castaway. CTD casts were performed near freshwater lenses to investigate the vertical and horizontal temperature and salinity structure associated with the lens. The drifters had three different lengths of drogues: 0 m, 2.5 m, and 5 m. They were equipped with a Bad Elf GPS unit or an iPhone GPS. Drifters with different lengths of drogues were deployed near freshwater lenses to observe the near surface currents. The wave buoy had a Yost accelerometer to determine wave period and height. Deployments were conducted near freshwater lenses to determine different wave structure on each side of the frontal interface.

Purpose:

These data were collected to study freshwater lens dynamics in the Mississippi River plume as a part of the CARTHE/SPLASH field campaign. They also aid in the study of the sea surface microlayer.
