   analysis of marine particulate and colloidal material for transition
   metals.  IN:  Marine Particles: Analysis and Characterization,

   Notes:
 
   1.  Particulate Mn and Al concentrations are in nmoles/liter.
   2.  Samples were collected by pressure filtration under nitrogen directly from
   the rosette bottles through 144 mm 0.4 micron Nuclepore filters held in
   Teflon filter sandwiches.
   3.  "leach" and "refrac" designate "acetic-acid leachable" and "refractory"
   (microwave digestion with HCl/HNO3/HF) fractions, respectively.
   4.  Stations N2-N9 were sampled from the TM rosette.  Stations S2-S13 were
   sampled using University of Washington bottles on the "Monster rosette"
   (See event log).  TM rosette samples were processed on deck. UW bottles
   were taken into lab and processed in a positive-pressure 2x4 lumber and
   sheet plastic clean enclosure equipped with a HEPA-filtered clean air
   supply.
