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:

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

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

The following are the calibration values:

Study area:
Mean: 1.15

The fundamental objectives of United States Global Ocean Ecosystems Dynamics (U.S. GLOBEC) Program are dependent upon the cooperation of scientists from several disciplines. Physicists, biologists, and chemists must make use of data collected during U.S. GLOBEC field programs to further our understanding of the interplay of physics, biology, and chemistry. Our objectives require quantitative analysis of interdisciplinary data sets and, therefore, data must be exchanged between researchers. To extract the full scientific value, data must be made available to the scientific community on a timely basis.

U.S. GLOBEC (GLOBal ocean ECosystems dynamics) is a research program organized by oceanographers and fisheries scientists to address the question of how global climate change may affect the abundance and production of animals in the sea.

The U.S. GLOBEC Program currently had major research efforts underway in the Georges Bank / Northwest Atlantic Region, and the Northeast Pacific (with components in the California Current and in the Coastal Gulf of Alaska). U.S. GLOBEC was a major contributor to International GLOBEC efforts in the Southern Ocean and Western Antarctic Peninsula (WAP).
