November Seawater Data

Posted on by

This month is the first month with the new seawater sampling method. After several months of trying out the YSI digital salinity and temperature meter our contact at IOS told us to just use that instrument. Once a month we are to collect a sample using the old method with the thermometers and hydrometer in order to track any drift on the digital meter and to be able to calibrate the data.

helicopter and new seawater sample methods

Posted on by

Cloudy with light wind in the morning. Calm seas. Rain. Moderate NE winds in the afternoon. Low East swell.

The helicopter landed  around 1000 hrs
It came in from the East. Circled Greater Race once. Then on it’s second trip around it nosed in from the South-East and landed on the helicopter landing pad at 1007.
As best as I can tell there were 3 people inside it.
They stayed for less than 5 minutes. The guy in the back at the sliding door took pictures of the lighthouse. In the photograph you can see he’s only using his cell phone.
The number on the side was 437.

Our seawater sample methods have changed as of tomorrow. Our contact at IOS informed me that we will now only be using the digital YSI salinity and temperature meter. And once a month we are supposed to collect a sample using the old method for quality control and to monitor any measurement drift on the digital meter
