PI notes and methodology:

Sediment trap arrays
--------------------
1. Organic geochemistry sediment trap arrays were deployed on the WHOI-OSU sediment trap
   moorings at 3 of the 5 mooring sites, 1, 3, and 4.  See Honjo et al 1999  Monsoon-controlled
   export fluxes to the interior of the Arabian Sea.  Deep-Sea Research Part II:
   Topical Studies in Oceanography.  46, 1859-1902.
2. Arrays deployed during the winter monsoon consisted of 2 NM-IRSC traps, 1 WM-IRS trap, and
   1 NVC trap.
3. Arrays deployed during the summer monsoon consisted of 1 NM-IRSC traps, 1 WM-IRSC trap,
   1 NM-IRS trap, and 1 NVC trap.
4. Non-carousel traps (IRS and NVC traps) collected material from the time of deployment until
   the time of retrieval.
5. Closing date and time of each cup is the opening date and time of each succeeding cup.
6. The IRS valved sediment trap design is described in Peterson et al.  1993.  Field evaluation
   of a valved sediment trap.  Limnology and Oceanography, 38, 1741-1761.
7. Photographs of the IRS traps and actual ASPS deployments are available at
     http://boto.ocean.washington.edu/aog/traps/irs_traps.html

Sample treatment
----------------
Samples were treated similarly to those described in Hernes et al 2000 (submitted DSR)
with the exception that only HgCl2 was used to poison the samples.  All sample splits were
made using a McClean WSD-10 wet sample splitter.

CHN analyses were done according to the method of Hedges and Stern, 1984. Carbon and Nitrogen
determinations of carbonate containing solids.  Limnology and Oceanography, 29, 657-663.
