This website makes available shipboard CTD data as temperature and salinity profiles, temperature and salinity diagrams and contours from nearshore stations obtained over twenty four cruises spanning November 1991 through January 2014 and yielding 2265 CTD casts. The profiles also show our picks of the critical depths using the methods presented in Martinson and Iannuzzi, 1998. The depths shown, with their symbols in parenthesis, are: ice growth onset (x), seasonal mixed layer (Δ), base of the seasonal pycnocline (∇), winter mixed layer (o), base of the permanent pycnocline, last ice growth (x).
