Dataset Description

Southern Ocean GLOBEC Five Minute ADCP Data

 

Quality

The following datasets have been processed and represent fairly accurate results. However, these datasets may undergo additional editing. The user is therefore cautioned that the files listed here for download may not be the final datasets.

If you would like to be notified when updated versions are available, email Susan Howard and you will be put on a list. Otherwise, please check back for updates. Notes on the quality of each data set are included in the downloads.

Format

The datasets have been created using MATLAB. They are converted to ASCII before serving using the JGOFS data management system. The files are also available for download in their original, zipped form. Each *.zip file contains a *.mat file and a readme.txt file. See the URL below for access to the original Matlab files.

 

Single Ping Data

Single ping data from all cruises have been archived, but are not yet available for distribution by ESR.

For additional documentation of the ADCP data collected during Southern Ocean Globec and for access to the original Matlab files, see http://www.esr.org/globec_index.html and http://www.esr.org/globec/adcp_data.html .

Acquisition Description

In 2001, the RVIB NB Palmer and RVIB LM Gould were upgraded to collect a full suite of data needed for full single-ping editing (i.e. processing single pings to ocean velocities). LMG0103, LMG0104, and LMG0106 were collected before the new system was implemented. The single ping data from these cruises can only be used as an aid for looking at amplitude (backscatter). NBP0103, NBP0104, NBP0202, NBP0204, LMG0201A, LMG0203, LMG0205, and LMG0302 datasets contain the complete set of data needed for processing the single ping data.

Instruments

Dataset-specific Instrument Name
Acoustic Doppler Current Profiler
Generic Instrument Name
Acoustic Doppler Current Profiler
Dataset-specific Description
Acoustic Doppler Current Profiler, encompasses an array of band widths and frequencies
Generic Instrument Description
The ADCP measures water currents with sound, using a principle of sound waves called the Doppler effect. A sound wave has a higher frequency, or pitch, when it moves to you than when it moves away. You hear the Doppler effect in action when a car speeds past with a characteristic building of sound that fades when the car passes. The ADCP works by transmitting "pings" of sound at a constant frequency into the water. (The pings are so highly pitched that humans and even dolphins can't hear them.) As the sound waves travel, they ricochet off particles suspended in the moving water, and reflect back to the instrument. Due to the Doppler effect, sound waves bounced back from a particle moving away from the profiler have a slightly lowered frequency when they return. Particles moving toward the instrument send back higher frequency waves. The difference in frequency between the waves the profiler sends out and the waves it receives is called the Doppler shift. The instrument uses this shift to calculate how fast the particle and the water around it are moving. Sound waves that hit particles far from the profiler take longer to come back than waves that strike close by. By measuring the time it takes for the waves to bounce back and the Doppler shift, the profiler can measure current speed at many different depths with each series of pings.

Project Information

U.S. GLOBEC Southern Ocean (SOGLOBEC)


Coverage: Southern Ocean


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.

Program Information

U.S. GLOBal ocean ECosystems dynamics (U.S. GLOBEC)


Coverage: Global


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).
