Nature shows its teeth
Today is Labour Day, and morning conditions were characterized as slightly overcast at 4 degrees Celcius and winds at 15 knots from the south. Forecast conditions predicted increasing winds and waves, along with a chance of showers this afternoon, and as usual, morning operations were underway quickly. We remained in transit just west of Erebus Bay in Victoria Strait, a location where we will continue to comb for signs of Terror until next week.
CHS's Tim Janzen and Rudy Cutillo made their way by helicopter to the GPS receiver on Racon Island to recover the data being logged at that site and replenish the batteries. As data was being retrieved it was noted that the local Arctic hares had recently enjoyed chewing on the cables. Fortunately the equipment remained fully functional, but steps were taken to provide additional protection for the cables so that the logger could be left on site to continue gathering information.
On ship, the CCG crew prepared for deployment of the Investigator, Gannet and Kinglett. The Laurier methodically followed course with the multibeam actively engaged. All of the seabed information being collected is feeding nicely into the CHS baseline information needed to expand the marine corridors in these waters, and the hydrographers are making great use of each opportunity to gather new data wherever possible.
As expected, waves grew in height throughout the day tossing the launches about while they surveyed. It's tricky for the coxswains to hold their survey lines in these conditions, but the ability to see their results in real-time on the onboard screens helps to make instant adjustments to their steering. By 6:00 pm, all launches were heading in for the evening. The advantage of Laurier's size is that her surveying continued unimpeded until morning.
