Salinity at the Dock
Two sensors at about 1m depth take measurements every second at the deep well at the WHOI dock in Woods Hole Village. The measurements are processed and archived remotely and posted every hour, on the hour. These are self-cleaning sensors that prevent biological fouling from degrading the salinity measurement. However, transient biota can cause a salinity spike (usually low) and we have made some attempt to filter these out in the data displayed here.
Contact Ray Schmitt at WHOI ext. 2426 with any questions or to request data.
The two CT sensor with self-scrubbing heads. The heads (lower end) rotate to scrub the sensors and enclose them in an antifouling environment when not sampling.
