PI notes for Bacterial Production Rates

13 November 2008: Prepared for OCB data system by Steve Gegg, BCO DMO (WHOI)
from documentation contributed by data set PI.

Original data were contributed by PI as an Excel file (VERTIGO_BP_data_to_OCB.xls).

Contact: Benjamin Van Mooy (WHOI)

Sampling and Analytical Methodology

Bacterial produciton (BP) rates were determined using the thymidine (TdR) incorporation rate method
as described by Steinberg et al (2008, L&O 53: 1327-1338)

BP rates in this table were calculated assuming 2E18 cell (mole TdR)^-1 and 1.5E-14 g C (cell)^-1

Modifications to Original Data

date reformatted to YYYYMMDD
column headers edited to BCO-DMO convention

Cruise_ID added manually to both KM0414 and RR_K2 data

date, event, lon, lat from cruise logs merged with original data based on ev_code

KM0414/ALOHA ev_code generated from the following information in PI e-mail on 07/17/2008
what do the ALOHA numbers 2823-2801 and 8424-8401 refer to?
The first two digits, 28 and 84, refer to the CTD cast.
The second two numbers refer to the Niskin bottle #.

RR_K2/K2 ev_code generated from the following information in PI e-mail on 07/17/2008
and similarly for the K2 data?
what are the numbers in column A?
The number in column A are Phil Boyd's sequential numbers of the BP samples.
I'm pretty sure the "biocast 2 8/2/2005" is ctd 23; "8/4/2005" is ctd31; "ctd 63" is ctd 63; and "8/15/2005" is ctd 72.
The BP incubations take over a day to completely work, so I think Phil used the date the incubations were completed in the notes he provided me.
