AL9801 acoustic backscatter relative decibels, Georges Bank, 1998 Dataset Description: <p>These relative decibel values are the result of processing the AL9801 Greene Bomber volume backscatter at 120KHz. They are relative decibel values derived from the backscatter data (in volts) and normalized according to the algorithms in the Matlab routine docurtainnf.m. The algorithm includes the following steps:</p>
<ol>
<li>Add 10 to each value</li>
<li>Multiply result by 10<sup>10</sup> to get values with units of m<sup>2</sup>/m<sup>3</sup> (called sv)</li>
<li>Take the log (called SV)</li>
</ol>
<p>These are energy backscattering values.</p>
<p>The values are presented as twenty groups of 20 numbers in each group. Each number is displayed as NNN, where there is an assumed decimal point at NN.N and all values should be negated. That is NNN, is really -NN.N.</p>

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 Georges Bank
<p>The U.S. GLOBEC <a href="http://globec.whoi.edu/globec-dir/about_georges_bank.html">Georges Bank</a> Program is a large multi- disciplinary multi-year oceanographic effort. The proximate goal is to understand the population dynamics of key species on the Bank - Cod, <a href="http://globec.whoi.edu/images/haddock103.07.gif">Haddock</a>, and two species of zooplankton (<a href="http://globec.whoi.edu/images/calanus-finmarchicus.html"><em>Calanus finmarchicus</em></a> and <a href="http://globec.whoi.edu/images/pseudocalanus.html"><em>Pseudocalanus</em></a>) - in terms of their coupling to the physical environment and in terms of their <a href="http://globec.whoi.edu/images/targetpp.gif">predators and prey</a>. The ultimate goal is to be able to predict changes in the distribution and abundance of these species as a result of changes in their physical and biotic environment as well as to anticipate how their populations might respond to climate change.</p>
<p>The effort is substantial, requiring broad-scale surveys of the entire Bank, and process studies which focus both on the links between the target species and their physical environment, and the determination of fundamental aspects of these species' life history (birth rates, growth rates, death rates, etc).</p>
<p>Equally important are the modelling efforts that are ongoing which seek to provide realistic predictions of the flow field and which utilize the life history information to produce an integrated view of the dynamics of the populations.</p>
<p>The U.S. GLOBEC Georges Bank <a href="http://globec.whoi.edu/globec-dir/EXCO.html">Executive Committee (EXCO)</a> provides program leadership and effective communication with the funding agencies.</p>

PI Supplied Instrument Name: Instrument Name: Greene Bomber Instrument Short Name:Greene Bomber Instrument Description: The Greene Bomber is a ENDECO V-fin towed body with overall dimensions of length: 139.7 cm; width at front: 66 cm; width at rear: 142.2 cm; height: 48.26 cm. It is constructed primarily of fiberglass. Since the early 1990's it has been towed just below the sea surface with acoustic and environmental sensors to provide continuous profiles of the water column acoustic backscattering and target strengths from zooplankton with a size range of ~ 1.5 mm to 100 mm, and sea surface environmental properties (temperature, salinity, and fluorescence). It was first used with a BioSonics dual-beam acoustic system operating at 420 kHz and 1 MHz or 120 and 420 kHz. The environmental sensing system (ESS) was the ESS used on MOCNESS. In 1997 the acoustics were changed to a HTI acousitic system with 120 and 420 kHz transducers. In 2010, two additional HTI transducers (43 and 200 kHz) were added. For additional detail see:
