U.S. GLOBal ocean ECosystems dynamics
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).

U.S. GLOBEC Southern Ocean
<p>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.</p>

<p>Oxygen analysis: Prior to each series of analysis the titrator was standardized with a solution of KIO3 (standard solution concentrations are listed in the calculation workbook). Standards were titrated until agreement reached +/- 2 <em>u</em>L. A reagent blank determination was conducted at the start of the cruise and used throughout. Titrations performed on the Langford Amperometric system were logged during operation and the titration data stored.</p>
<p>Nutrient determinations were conducted on an Alpkem Flow Solutions segmented flow autoanalyzer. Operation and standardization of the system is described in detail in the Flow Solutions manual under the file "Alpkem manuals". Linearity checks were conducted at the beginning of the cruise for each of the ions and conducted at the start and completion of each sample sequence. Efficiency checks on the Nitrate reduction column (OTRC, Alpkem) were run after introduction of the column into the analytical stream. Analysis integrity was also checked by sampling surface and bottom water bottles in duplicate. This process was repeated on most casts.</p>
<p>Significant difficulty was experienced with the SBE oxygen sensor on the CTD instrument package. Agreement between the titration determinations of oxygen and logged values through the CTD instrument package was extremely variable and suggested several sources of error. Under the directory containing bottle data, two jpeg format files contain comparisons of the SBE output and other parameters taken by the CTD package and the Winkler determinations. In property:property comparisons with other parameters collected by the package (i.e. Temperature, Salinity) variability was obvious and difficult to explain. Investigation into this variability suggested dependence on the rate of decent as well as strong dependence on the extreme cold temperatures and ice problems. During the cruise a second sensor was installed as a secondary. This sensor reported higher concentrations but similar trends. An intercomparison with the CTD package operated on the NBP was carried out on September 1 (Event 201/LMG24402.001). Comparison of the data files showed significantly higher concentrations reported by the NBP system agreeing with the Winkler titration values.</p>

Conductivity, Temperature, Depth
Conductivity, Temperature, Depth
PI Supplied Instrument Name: Conductivity, Temperature, Depth PI Supplied Instrument Description:Seabird, model not identified Instrument Name: CTD - profiler Instrument Short Name: Instrument Description: The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column. It permits scientists to observe the physical properties in real-time via a conducting cable, which is typically connected to a CTD to a deck unit and computer on a ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast.
This term applies to profiling CTDs. For fixed CTDs, see https://www.bco-dmo.org/instrument/869934. Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/130/
