Abstract

This dataset includes nutrient and metal data along with CTD data collected on R/V Knorr cruise KN192-05, "CoFeMUG", from November to December 2007.

Cite Dataset

Analysis of nutrients, cobalt (total and labile), dissolved iron, and dissolved manganese of water samples drawn from Trace Metal Rosette (TMR) bottle casts. CTD dataset is combined from both sensors. Missing CTD was due to lack of sensor package on the trace metal rosette (Stations 1, 25, 27, and some repeat Station 13 casts) or technical issues (battery failure, Station 9). Selected CTD depths (usually the deepest) were not included when O2 sensor values were anomalous (i.e. negative values).

This dataset is related to the BCO-DMO Dataset Nutrients and Metals (https://www.bco-dmo.org/dataset/3233); however, this dataset also includes the CTD data.
