  • a At all depths, values for Ti were <0.005 mg liter−1, values for Se were <0.010 mg liter−1, and values for Hg and Ag were <0.05 mg liter−1. ND, no data.

  • b Dissolved O2 readings below 0.5 mg liter−1 are considered to be below detection, but absolute instrument readings are reported.

  • c Cond, conductivity.
