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

Calm this morning, with mixed weather all day. Started out SE, backed to Westerly. Periods of torrential rain. DND blasting: 1200, 1205. Both big, loud single bangs.

Tour boats: 9

22 Canada Geese
Keeping my eye out for Sooty Shearwaters, no sign yet

Mammal Count from tower at 1130
9 elephant seals behind boat shed and on jetty 47 harbour seals (mostly Middle Rocks)
129 Stellar sea lions (mostly along the North shore of the main island)
200 California sea lions (mostly along the South shore in front of the student house)
Seems like this bad weather compelled a lot of the sea lions to leave. Maybe they’re just out in the water waiting for the swell and surge to ease up.

I spotted the Stellar sea lion with the line around his neck again today and got a few pictures.

-entered and sent water sampling data to IOS
-compiled month end report
-photographed branded sea lions
-fixed electric fence after storm damage
-tidied keepers house

I’m very grateful to have spent another wonderful summer out here at Race Rocks but today is my last day on the island. Tomorrow, Max will take over for a week and will be training the following person who will be here for the fall.

Collecting salinity and temperature measurements with the new YSI instrument off the jetty

Collecting salinity and temperature measurements with the new YSI instrument off the jetty

The DFO has sent out a new YSI instrument which means we can take salinity measurements now which will be posted that the end of the month with the temperature and density readings.

 

Weather has been very calm with low winds with the exception of yesterday when the wind picked up and we got some rain.
