9-23 April 2018 – Nearly 2 m of sand accreted over our pressure sensor buried in the mouth of Los Peñasquitos Lagoon, making it 3 m beneath ground level. After recovering the sensor in the surfzone and attempting to recover the lagoon mouth sensor, we had to resort to heavy machinery. Since the lagoon mouth was in the process of closing, recovery was a priority before the lagoon filled with water and the recovery became impossible. After a couple long days in the field, the pressure sensor was successfully recovered!
Thanks to Erik Jepsen/UC San Diego Publications for some amazing photographs taken on the first day (before the heavy machinery!). And of course thanks to the amazing field crew – could not have done it without the immense efforts of Brian, Kent, Greg, Lucian, Rob, and Bill!
