Description

Underway Chloro and Phaeo Pigments,
Hull Intake Sampling

Methods:
Surface chlorophyll samples were collected from the ship's flow-through seawater system, which has seawater intakes between 5 and 7 meter depths on both ships. About one liter of seawater was vacuum filtered onto GF/F filters and passively extracted in 7 ml of 90% acetone at -20deg C in the dark for at least 24 hours. Chlorophyll fluorescence was then measured on a Turner Design Digital 10-AU-05 fluorometer calibrated prior to the cruise.

Calibration Values

Southern Ocean GLOBEC II - Nathaniel B. Palmer 01-04

Notes:
Performed serial dilution calibration at start of cruise using Sigma Chemicals chl_a standard.

The following are the calibration values:

	Fd		tau
H	0.109	H	1.970
M	0.111	M	1.950
L	0.109	L	1.928

Southern Ocean GLOBEC III - Laurence M. Gould 02-03

Notes:
