Imagery from USGS CoastCam deployed at Madeira Beach, Florida

A digital video camera was installed at Madeira Beach, Florida (FL) and faced west along the beach. Every hour during daylight hours, daily from 2017 to 2022, the camera collected raw video and produced snapshots and time-averaged image products. The images included in this data release were collected from January 21, 2017, to December 31, 2017. The camera is part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. USGS researchers analyzed the imagery collected ...

Intrinsic and Extrinsic Calibration Data From USGS CoastCam deployed at Madeira Beach, Florida

A digital video camera was installed at Madeira Beach, Florida (FL) and faced west along the beach. Every hour during daylight hours, daily from 2017 to 2022, the camera collected raw video and produced snapshots and time-averaged image products. This data release includes the necessary intrinsic orientation (IO) and extrinsic orientation (EO) calibration data to utilize imagery to make quantitative measurements. The camera is part of a U.S. Geological Survey (USGS) research project to study the beach and ...

Time-series data on currents, waves, and turbidity off Santa Cruz, CA, 2014-2015

Time series data of water surface elevation, wave height, currents, and turbidity were acquired during the winters of 2014-2015 and 2015-2016 in support of a study on the morphological change of rippled scour depressions off Santa Cruz, CA. One set of instruments (SCW) was mounted at the end of Santa Cruz Municipal Wharf during both winters. Another set of instruments (M1T) was deployed offshore in Monterey Bay each winter; the two offshore winter locations were different, but each were about 0.5 km ...
