North and South Again
On reaching the Falkland Islands we went into Berkeley Sound just north of Stanley to calibrate the echo sounders. We had been prevented from doing this in the South Shetlands by the ice. The weather couldn't have been more different, as we were treated to a sunny and still summer day. This not only allowed us to complete the calibration, but make a flying start to the demobilisation and maintenance.
The echo sounders in the ship's hull and those installed in Autosub are of the same make and type, but need to be cross checked with standard targets, hence the need for calibration. The standard targets are metal spheres that are suspended in the beam of each transducer; readings can be compared to ensure each transducer is reading the same strength of signal.
However, while doing this work the ship was surrounded by lobster krill swarms. These are a different species of animals compared to the krill we were fishing for and studying with TUBA, mentioned in last weeks diary entry. In the pictures below you can make out the pink line of one swarm alongside the ship and of course having biologists onboard some just had to be caught, the right-hand picture shows one of these chaps. The biologists and most people enjoyed seeing the krill alongside, although we cannot vouch for the engineers who spent an "interesting" evening evicting our little friends from their sea-water intakes. The only way that one filter was cleared was to lift the strainer out with a chain block, such was the quantity of their catch.
The week has ended with us off to the Antarctic Peninsula to start a survey of which we shall give more details in the future. The weather on the other hand is just the same with us being rocked gently to sleep in our bunks - not... The picture at the top is as it is now, happy sailing again.
Welcome Onboard to Year Six.
During our call to Stanley we were able to welcome onboard most of the members of Year Six from the Falklands Islands Primary School and four teachers. During their visit they were hopefully given an impression into the workings of the ship and some of the science we had just completed.
All appeared to enjoy their visit and looked forward to appearing on the web so we hope we have everyone pictured below enjoying pop and crisps afterwards in the Officers/Scientist lounge.
Students from Year Six of the Falklands Islands Primary School.
Time In Stanley
Due to the flying start that a day in Berkeley Sound gave us, the demobilisation was almost complete by the time we docked in Stanley. Leaving the evenings free to enjoy the summer sunshine. Pictured below are some of our activities, ranging from the gentle to the more energetic.
