This section is based on measurements made during October of 2003 in Halifax Harbour by students in the Introduction to Physical Oceanography class at Dalhousie University, taught by Dan Kelley; supervision at sea was provided by teaching assistant Natacha Bernier, at the time a PhD student at Dalhousie. Note the alteration of two station locations, to correct typographical errors that were made at sea, perhaps by someone who was distracted by the boat motion.

stn15 <- ctd.decimate(ctd.trim(read.ctd("BED0315.CNV")),p=p)
stn15$latitude <- stn15$latitude + 1
stn15 <- processing.log.append(stn15, "DEK add 1 to latitude, correcting a typo")
section <- make.section(stn08, stn09, stn10, stn01, stn11, stn12, stn13, stn15)
The stations cover a 14 km region running from station 308, near the Sackville River, seaward to station 315, at the entrance to the general Harbour, offshore of the lovely Point Pleasant Park.
