Tide Staff Appreciation Day: Thanks, tide staff, for helping us check the position of the water pressure-sensing equipment and ensure that our tide measurements are accurate.

After the tidal gauge was installed, we had to confirm that the orifice hadn’t shifted. To do this, we take manual readings of the tide using a staff that the crew set-up during installation of the tidal station. To take manual (staff) observations, you just measure and record the water level every 6 minutes. If the manual (staff) observations match the readings we are getting from the tidal gauge, then the orifice is likely in the correct spot... As you can see, accounting for the tides is a complex process with multiple checks and double checks in place. These checks may seem a bit much, but a lot of shifting and movement can occur in these areas. Plus, these checks are the best way to ensure our data is accurate." - Lauren WilmothRead the blog post
