| Survey Equipment | Survey Info | Data Type(s) | Data Collected |
|---|---|---|---|
| pistoncore | --- | Geology | Grain size and charcoal abundance in sediment samples (Sediment samples were collected from Los Padres reservoir using a CME-45 barge-mounted drill rig, to characterize sedimentary properties in the reservoir deposits following the Soberanes Fire of 2016 and high river flows in winter 2017.) Lead, Radium, Cesium, and Thorium isotope activity in sediment samples (Sedimentary properties in the reservoir deposits following the Soberanes Fire of 2016 and high river flows in winter 2017.) |

Orthomosaic imagery (This portion of the data release presents a high-resolution orthomosaic image of the exposed Los Padres Reservoir delta where the Carmel River enters the reservoir.) Aerial imagery from the UAS survey (This portion of the data release presents the raw aerial imagery collected during the unoccupied aerial system (UAS) survey of the Los Padres Reservoir delta, Carmel River valley, CA, 2017-11-01.) Digital surface model (DSM) and digital elevation model (DEM) (This portion of the data release presents a digital surface model (DSM) and digital elevation model (DEM) of the exposed Los Padres Reservoir delta where the Carmel River enters the reservoir. The DSM represents the elevation of the highest object within the bounds of a cell. The DEM represent the elevation of the ground surface where it was visible to the acquisition system.) Topographic point cloud (This portion of the data release presents a topographic point cloud of the exposed Los Padres Reservoir delta where the Carmel River enters the reservoir. The point cloud was derived from structure-from-motion (SfM) processing of aerial imagery collected with an unoccupied aerial system (UAS) on 2017-11-01.) |
