This submission contains two current-speed datasets collected in January 2024 in the Humboldt Bay channel near the Hog Island Oyster Farm in northern California. One current speed dataset was collected near the Hog Island Oyster Farm pier in the Humboldt Bay channel and the other dataset was collected in the middle of the channel. A Nortek Eco Acoustic Wave and Current profiler (ADCP) was used, which measures horizontal water velocity throughout the lower half of the water column. Additionally, the ADCP only measures currents up to about 1.6 m/s depending on the tilt of the device. Above that the current speeds are labeled as "nan". The data will be useful for turbine or current energy converter companies who may want to install devices in the Humboldt Bay channel. Two current speed collection sites: 1. Pier Site - at the Hog Island Oyster Farm pier (40.793941, -124.192461). 2. Channel Site - mid-channel in Humboldt Bay (40.793676, -124.191227).
