June 22: Up and down

Today had its ups and downs… 98 ups and downs to be precise: The VMP samples the water column like a yo-yo: Up and down… When releasing it, it falls down with a constant velocity and measures salinity, turbulent mixing, and many other variables. Then, we recover it with a motorized deep-sea fishing reel. One cast takes about 3min which allows great spatial resolution. Check out our salinity transact below.

Salinity transact of the VMP. We travelled northward, left the
intrusion (yellow colored sections) , and captured the intrusion’s nose on
the way out. In the north you see colder and fresher shelf water. The
intrusion moves northward by “sneaking” into a density gap between two
different water layers.
