Description: 
Type of cast: BBG = using a benthic boundary gradient sampler with 50 mL syringes on OC2107A. Note that instead of depth, this variable now refers to height above seafloor in centimeters; CTD = using a traditional 10 or 14 L bottle mounted on a rosette; TMC= using a trace metal clean 5 L bottle mounted on a trace metal clean rosette following Geotraces protocols; TMC dFe only = Trace metal cast and only dissolved Fe was measured (i.e. not Fe(II))); these are the stations where dFe was measured the first time but Fe(II) wasn't, so we resampled and got the Fe(II).
