Today, a group of 6 students and 3 instructors went on the R.V. Barkley Star – 35 knots is a lot faster 9 knots and a bumpy but short ride took us to Effingham Inlet. The inlet is narrow, sometimes only a few hundred meters with very steep walls rising a few hundred meters on both sides. The streams mostly come down as waterfalls. Oceanographically, it is interesting because some of the deep basins have no oxygen in the bottom layer. Here Kathy shows a Winkler
water sample which has been treated to react all of the oxygen in the water into a purple chemical. As you can see the sample has no color – and thus no oxygen. And the water smells like the old dead worms at the bottom of my swimming pool in the Spring- another clear sign of no oxygen.
In the evening we gathered at the Rix center at the Bamfield Marine Center. The open airy space at the Rix is a good antidote to the sometimes dreary wetness of the coast.
